The precise structures of both the Information Commons and Knowledge Network of Disease remain to be determined and would be informed by pilot studies, as discussed in Chapter 4. Given the inclusion of multiple parameters ranging from genomic to environmentally modulated disease factors, the Information Commons would likely have a multi-layered structure with each layer containing the information for one disease parameter, such as “signs and symptoms”, genetic mutations, epigenetic patterns, metabolic characteristics, or other risk factors (including social, behavioral, and environmental influences). The Information Commons should register all measurements with respect to individuals so that the multitude of influences on pathophysiological states can be viewed at scales that span all the way from the molecular to the social level. Only in this way could, for example, individual environmental exposures be matched to individual changes in molecular profiles. These data would need to be stored in an escrowed, encrypted depository that allows graded release of data depending on the questions asked, the access level of the individual making the inquiry, and other parameters that would undoubtedly emerge in the course of pilot studies. The Committee realizes that this is a radical approach and intense public education and outreach about the value of the Information Commons to the progress of medicine would be essential to harness informed volunteerism, the support of disease-specific advocacy groups, and the engagement of other stakeholders. The Committee regards careful handling of policies to ensure privacy as the central issue in its entire vision of the Information Commons, the Knowledge Network of Disease, and the New Taxonomy. The Knowledge Network of Disease, created by integrating data in the Information Commons with fundamental biological knowledge, drawn from the biomedical literature and existing community databases such as Genbank, would be the centerpiece of the informational resources underlying the New Taxonomy. In order to extract relationship information between multiple parameters—for example, the transciptome and the exposome—the multiple data layers must be inter-connected (see Figure 3-1: Building a Biomedical Knowledge Network for Basic Discovery and Medicine. Ideally, each information layer would be connected to every other layer: thus, “signs and symptoms” would be linked to mutations, mutations to metabolic defects, exposome to the epigenome, and so forth. The links could be one-to-one but most commonly would be many-to-one, and one-to-many (e. Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 45 layers could be characterized through a variety of representations that attempt to extract meaning from the Information Commons. Meanwhile, different types of lymphomas, defined by transcriptome analysis, may have distinct metabolomic profiles. The similarities of multiple diseases could be discerned either from relationships among the networks of individual parameters (e. A highly interconnected Knowledge Network would link multiple individual networks of parameters in a flexible way. A user could chose to interrogate only a small part of the network by limiting his or her analysis to a single information layer, or even a small portion of this layer; alternatively, a user could interrogate the complex interrelationship of multiple parameters. High flexibility ensures easy cross-comparison and cross-correlation of any desired dataset, making it a versatile tool for a wide spectrum of applications ranging from basic research to clinical studies and healthy system administration. Widely accessible The Knowledge Network would need to be accessible and usable by a wide range of stakeholders from basic scientists to clinicians, health- care workers and the public. Furthermore, the available information would need to be mineable in ways that are custom-tailored to the needs of different users, possibly by implementation of purpose-specific user interfaces. While the Committee agreed upon the generalities listed above and illustrated in Figure 3-1, about the Information Commons and Knowledge Network —and their relationship to a New Taxonomy— specifics of implementation such as the detailed design of the Information Commons, the information technology platforms used to create it, questions about where key infrastructure should be physically housed, who would oversee it, and how the Information Commons would be financed, were considered beyond the scope of the Committee’s charge in a framework study. Nonetheless, dramatic developments in the fields of medical information technology—and other developments discussed in Chapter 2—give the Committee confidence that the creation and implementation of this ambitious and novel infrastructure is a feasible goal. The Proposed Knowledge Network Would Fundamentally Differ from Current Biomedical Information Systems Immense progress has been made during the past 25 years in organizing our knowledge of basic biology, health, and disease, even as many components of this knowledge base have grown super-exponentially. Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 46 The key difference is that the information commons, which would underlie the other databases, would be “individual-centric. An independent researcher, who was not involved in the study that contributed these entries, has no way of knowing that they are from the same individual. As a consequence, relationships between multiple parameters that determine disease status in a given individual are impossible to extract. This information was not collected in a way that allows the individual to be the central organizing principle, and no amount of redesign of the inter-connections between different entries in the current system could achieve the goals the Committee has outlined. The Committee would like to emphasize the novelty and power of an Information Commons that is “individual-centric. For example, given the coordinates of a large number of, say, backyard barbecue grills, one can suddenly overlay a vast amount of socio-economic, ethnic, climatological, and other data on what—at the start of the investigation—appeared a peculiar, anecdotal inquiry. Despite significant challenges to constructing an individual-centric Information Commons, the Committee concluded that this is a realistic undertaking and would be essential to the success of the Knowledge-Network/ New Taxonomy initiative. The Committee is of the opinion that “precision medicine,” designed to provide the best accessible care for each individual, is not achievable without a massive reorientation of the information systems on which researchers and health-care providers depend: these systems, like the medicine they aspire to support, must be individualized. Generalizations must be built up from information on large numbers of individuals. Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 47 is lost when molecular profiles, data on other aspects of an individual’s circumstances, and health histories are abstracted away from the individual at the very beginning of investigations into the determinants of health and disease. A Knowledge Network of Disease Would Continuously Evolve Although knowledge of disease, and particularly molecular mechanisms of pathogenesis, is still limited, the pace of progress has never been greater. New insights into the biology of disease are emerging rapidly from a wealth of molecular approaches, as well as from new insights into the importance of environmental factors. However, the system for updating current disease taxonomies, at intervals of many years does not permit the rapid incorporation of new information, thereby contributing to the delayed introduction of advances that have the potential, over time, to guide mainstream practice. The individual-centric nature of an Information Commons is an important means of ensuring that the data underlying the Knowledge Network, and its derived taxonomy, would be constantly updated. Such a dynamic system would not only accept new inputs for established disease parameters, it would also accommodate new types of information generated by newly developed technologies, to identify, acquire, measure, and analyze new biological features of disease. The New Taxonomy Would Require Continuous Validation Bad information is worse than no information. A key feature of a clinically useful taxonomy is the requirement for a validation system. The logic of the classification scheme, and especially its utility for practical applications, needs to be carefully and continuously tested. This is particularly important when patients and clinicians use the New Taxonomy to inform clinical decisions. The New Taxonomy should be routinely tested to provide all stakeholders with data indicating the extent to which decisions guided by it can be made with confidence. Clearly, some patients and clinicians will be more comfortable than others with making decisions that are based on clinical intuition rather than proven evidence. However, a physician should be able to interrogate the Knowledge Network that underlies the New Taxonomy to learn whether others have had to make a similar decision, and, if so, what the consequences were. For example, if a drug has been introduced to target a particular driver mutation in a cancer, a physician needs to know whether or not rigorous clinical testing has determined that the drug is safe and effective. Is the drug effective only in some patients who can be identified in some way, such as by analyzing variants of genes that affect cell growth or drug metabolism? Similarly, if a laboratory test is considered to be a candidate predictor for the later development of disease, has that hypothesis been rigorously validated? Whether a given test is used to identify predictors of disease or the existence of disease, the test result must be interpreted in the context of knowledge about the “normal range” of results. This requirement is not a trivial consideration, especially for tests based on integration of vast amounts of data, such as the genome, transcriptome, and metabolome of the patient. Even with a conventional sequencing test, it is often difficult to ascertain with certainty whether a sequence change is disease-causing or insignificant. Some initial results from whole-human-genome-sequencing data indicate the scale of this problem: most individuals have dozens to hundreds of sequence variants that are readily recognizable, on biochemical grounds, as potentially pathogenic: examples include variants that cause premature-protein truncation or loss of normal stop codons (Ge et al. Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 48 obscure. Defining and continuously refining our understanding of the normal “reference range” for such tests would require being able to access and effectively analyze biological and other relevant clinical data derived from large and ethnically diverse populations. Ultimately, the Knowledge Network that underlies the New Taxonomy will make it possible to develop decision-support tools that synthesize information and alert health-care providers to all validated insights that emerge from the Knowledge Network and that are relevant to clinical decisions under consideration. The organizational and financial costs of systematically replacing these systems would be substantial. Such issues must be addressed but, given the magnitude of the tasks associated with launching the creation of the Information Commons and the Knowledge Network of Disease, and seeing it through its formative stages, their consideration can safely be postponed for many years. The Proposed Informational Infrastructure Would Have Global Health Impact A Knowledge Network of Disease should ultimately provide global benefits. Inevitably, the Knowledge Network initially would be devised primarily through data acquired, placed in the Information Commons, and analyzed by researchers and medical institutions in developed countries. However, a comprehensive and fully developed Knowledge Network of Disease must include the many diseases, including infectious diseases and disorders linked to geographically limited environmental exposures that are endemic in low- and middle-income settings throughout the world.

Each category may be further subdivided into uses for individual diets and for group diets (Figure 13-1). Included in this chapter are specific applications to the nutrients discussed in this report. There is no method to adjust intakes to account for under- reporting by individuals and much work is needed to develop an acceptable method. Furthermore, large day-to-day variations in intake, which are exhibited by almost all individuals, mean that it often takes a prohibitively large number of days of intake measurement to approximate usual intake (Basiotis et al. As a result, caution is indicated when interpreting nutrient assessments based on self-reported dietary data covering only a few days of intake. Data on nutrient intakes should be interpreted in com- bination with information on typical food usage patterns to determine if the recorded intakes are representative of that individual’s usual intake. Finally, because there is considerable variation in intakes both within and between individuals, as well as variation associated with the require- ment estimate, other factors must be evaluated in conjunction with the diet. The nutritional status of an individual can be definitively deter- mined only by a combination of dietary, anthropometric, physiological and biochemical data. Thus from dietary data alone, it is only possible to estimate the likelihood of nutrient adequacy or inadequacy. Furthermore, only rarely are precise and representative data on the usual intake of an individual available, adding additional uncertainty to the evaluation of an individual’s dietary adequacy. This approach is quantitative and should be used only when the data listed above are available. However, in the more common situation where the estimate of usual intake is not based on actual 24-hour recalls or records, but on dietary history or food frequency questionnaires, a qualitative interpretation of intakes can be used. For example, many practitioners use the diet history method to construct a likely usual day’s intake, but the error structure associated with this method is unknown. While the error associated with food frequency questionnaires has been evaluated (Carroll et al. Thus, a practitioner should be cautious when using this method to approximate usual intakes. Such considerations are not applicable in the case of energy intake, which should match energy expenditure in individuals maintaining desirable body weight (see later section, “Planning Nutrient Intakes of Individuals,” and Chapter 5). Infants who consume formulas with a nutrient profile similar to human milk (after adjustment for differences in bioavailability) are also assumed to consume adequate levels of nutrients. When an infant formula contains nutrient levels that are lower than those found in human milk, the likelihood of nutrient adequacy for infants who consume this formula cannot be determined because data on infants fed lower concentrations of nutrients are not avail- able. However, the intake at which a given individual will develop adverse effects as a result of taking large amounts of one or more nutrients is not known with certainty. Care must be taken to ensure the quality of the information upon which assessments are made so that they are not underestimates or overestimates of total nutrient intake. Estimates of total nutrient intake, including amounts from supplements, should be obtained. It is also important to use appropriate food composition tables with accu- rate nutrient values for the foods as consumed. First, the intake distribution must be adjusted to remove the effect of day-to-day variation of individual intake. The statistical adjustments are based on assumptions about the day-to-day variation derived from repeat measurements of a representative subset of the group under study (Nusser et al. When this adjustment is performed and observed intakes are thus more representative of the usual diet, the intake distribu- tion narrows, giving a more precise estimate of the proportion of the group with usual intakes below requirements (Figure 13-2). A statistical approach is then used to combine the information on nutrient intakes with the information on nutrient requirements in order to determine the apparent percent prevalence of nutrient inadequacy in the group. The Probability Approach Using the probability approach requires knowledge of both the distri- bution of requirements and the distribution of usual intakes for the popu- lation of interest. This method assumes that the intake and requirement distributions are independent, an assump- tion that is not valid for the energy requirements addressed in this report because energy intakes are highly correlated to energy expenditure. The cut-point method further assumes that the variability of intakes among individuals within the group under study is at least as large as the variability of their requirements. This is thought to be true for all of the macronutrients discussed in this report. Dietary intake data are available from the 1994–1996 Continuing Survey of Food Intakes by Individuals. Esti- mated intakes are based on respondents’ intakes, which were adjusted to remove within-person variability using the Iowa State University method (Appendix Table E-2). Examination of the distribution of usual carbohydrate intake reveals that intakes at the 1st and 5th percentiles are 87 and 118 g/day, respectively. Thus, fewer than 5 percent of women in this age group appear to have inadequate carbohydrate intakes. Currently, a method for adjusting intakes to compensate for underreporting by indi- viduals is not available, and much work is needed to develop an acceptable method.

Federal Medicare regulations forbid hospitals from offering physicians anything of value (including software and services) if it would influence their patterns of hospital utilization order 500 mg antabuse fast delivery. These statutes were intended to pre- vent hospitals from order genuine antabuse, in effect buy antabuse no prescription, bribing physicians to bring their pa- tients in buy antabuse online now. If compatible clinical software made it easier for physicians 86 Digital Medicine with a choice to use the facility that provided them the software, it might trigger fraud and abuse investigations. Tax laws provide another barrier to the sharing of clinical soft- ware between hospitals and physicians. The Internal Revenue Code and state laws forbid not-for-profit hospitals (recall that 85 percent of all community hospitals are not-for-profit) from giving physicians (or anyone else) anything of value. Competitive advantage for specific providers could be eliminated by regulation that requires clinical information systems developed by different vendors to interoper- ate (that is, to use common record formats, coding conventions, messaging standards, etc. This would mean that, once installed, physicians could use their clinical software in conjunction with any of the available local hospitals or retrieve information about their patients from any of them. The fact that software and services could be provided on a dial- in basis without significant capital expenditures by hospitals on the physicians’ behalf could help change some of the equation as well. The most expensive part of a physician office’s digital conversion is transferring all of its existing patient records to digital form so they can be used by the information system. If these costs can be surmounted and physicians can obtain password-protected access to computerized patient records and clinical decision support from their offices, it would be a major boost to overall computerization. Hospitals and Physicians Digitizing Patient Records Together Ideally, hospitals and physicians should move together to digitize patient records. Technical opportunities exist for hospitals to create Physicians 87 virtual private networks that segregate the physician’s clinical records from those of the hospital (as well as the rest of the Internet), protect the physician’s business autonomy and privacy, and still provide the transparency of information flow that is needed for optimal patient care. Physicians have to be willing to wade into the battle over how digital medicine is organized and be assured that their concerns about autonomy and privacy are recognized. When you sum the potential impact of various information tech- nologies across the physician’s world, the aggregate impact is im- pressive. Speed the flow of new knowledge to physicians and store it efficiently so physicians don’t have to rely on their memories 2. Guide and assist in patient care itself, wherever the physician or patient may be at the moment 3. Free physicians from paper records and bills, reducing their prac- tice expenses 4. Facilitate collaboration between physicians both in consultation and in learning As with hospitals, this progress will not come easily, quickly, or cheaply. Moreover, not all physicians will be able to realize all of these benefits at the same time. Physicians practicing in larger groups and clinic settings will find these tools become available to them sooner simply because their organizations have the financial resources and personnel to make them happen and the capability 88 Digital Medicine of experimenting with these tools before adopting them wholesale. Physicians in private practice will have to overcome mistrust of their hospitals and each other and work with their colleagues to build data systems they can use from the office or from home. However, what ails physicians stretches far beyond the curable logistical difficulties of medical practice itself. At the root of medicine’s midlife crisis is the nagging feeling on physicians’ part that patients and society no longer trust them. Consumers are sending physicians a message: be more available to us when we need your help, do not patronize us, and give us the information we need to help us manage our own health. The physicians who hear these messages develop new relationships with consumers and may find their practices acquire more meaning. Physicians who grasp this capability effectively will also find that they can grow their practices and, by making more efficient use of their own time, still devote more time to the patients who need the personal contact. Information technology can extend the power of the physician’s mind, a most valuable and fragile tool, and can help strengthen the doctor-patient relationship. As this relationship is improved, it may help lay the groundwork for a newer, more confident medicine. Although they may not believe it, physicians retain extraordinary power in our health system. All too often, they have used that power to retard needed changes in health policy and management. With information technology, however, physicians have a marvelous op- portunity to lead the transformation. Because they remain strategic actors, not only in health systems, but also in the lives of patients, physicians hold the key to “birthing” the digital transformation of the health system. For further, in-depth readings on the benefits of digitization on physicians, I recommend Digital Doctors by Marshall de Graffenried Ruffin, Jr. Trails Other English Speaking Countries in Use of Electronic Medical Records and Electronic Prescribing. Measured against this end point, the contem- porary health system in the United States has become increasingly user-unfriendly. The institutions of medical practice—hospitals, health plans, and physician organizations—have grown so large and become so intimidating that many of them dwarf those who give and receive care. As mechanisms for transmitting knowledge, healthcare organizations have become riddled with bureaucracy and institutional processes that impede the free flow of communication between patients and caregivers. Moreover, as discussed in Chapter 1, healthcare institutions have become prisons of vital medical knowledge. The knowledge and wisdom that all the actors in healthcare seek from medical institu- tions is imprisoned in paper, in indecipherable notes and images, in journals and professional reports that are often written in a private language few can understand, and in the overtaxed memories of caregivers. New knowledge is flooding into the health system at an accelerating pace, but ensuring that this vital new knowledge actually reaches the practitioners and consumers who need it is an urgent piece of unfinished business. The health system is there to serve them, and through their taxes and forgone salaries, they pay most of its bills. Managing consumer expectations for compassionate and responsive advice and care is the central challenge facing our health system. How we describe people in our health system is important and has significant consequences for how we think about them. In describing the role users play in the health system, traditional vocabulary and medical culture constrain us. The word “patient” increasingly fails to describe accurately the role of the user. Healthcare professionals generally view with disdain the use of the term “consumer” or “customer” to describe the health system’s “users” because they feel it commercializes the care relationship and demeans them as professionals. Physicians in particular resist com- mercial terminology, at least in part because they are uncomfortable with the economic implications of their professional power. However, the traditional term that describes the health system’s user as a “patient” (throughout this chapter, the term “patient” should be read with the current discussion in mind) is troublesome for several reasons. The more profoundly ill or disabled the patient is, the more likely that the decision maker is the family or a key family member. Many forms of care, such as ambulatory surgery or cooperative care in rehabilitation, explicitly recognize the role of the family member as a participant in the care team. In the case of chronic care, a very significant majority of the care is actually rendered by a family member, not “official” health professionals. At any given time, only a small fraction of the population, perhaps as few as 5 percent, are actually using the health system. When feeling well, they are not patients, and yet they play a role in the health system that the traditional vocabulary does not recog- nize. In the emerging genetic age, one may not have been officially diagnosed as “ill,” yet one carries a complex and highly individual pattern of genetic risk. This person may not be a patient in the traditional sense, but is engaged, to some degree consciously, in managing that risk nonetheless. Thus, although a person is not receiving care as a patient, he or she may be acquiring information about emerging health risks or medical problems that have not yet resulted in seeking care, arguing with the health insurer over paying a medical bill, participating in an online discussion of a medical issue, and so forth. When that step is taken, then, is that person a patient, or even a consumer, or merely a person living life? Odin Ander- son, famously referred to the role of the patient in the traditional health system as that of the “breathing brick. It is particularly in- accurate in describing the baby boom women who are, as discussed below, the “power users” in the present health system.

Alex Comfort devoted a whole book to the sordid history of the war on self-abuse discount antabuse 250 mg with amex, in which the medical pro- 143 fession was finally forced to retreat buy generic antabuse 500mg online. In the age of gallantry purchase cheapest antabuse and antabuse, atonement and retribution were not part of the moral code antabuse 250mg overnight delivery. Syphilis was not only a sin of the flesh, it was a vice, a sign of moral degeneration, a stigma of disgrace. The medical profession willingly accepted the role of controllers of social deviance, acting as state agents in combatting vice. At the same time they also took upon themselves the role of guar- dians of morality. In 1860, the famous London surgeon, Samuel Solly, President of the Royal College of Surgeons, regarded syphilis not as an evil but as a blessing, since it restrained unbridled passion. The cause of syphilis, Treponema pallidum, was discovered by Schaudinn in 1905 and in the next year, August von Wassermann devised a test for syphilis. In 1910 Paul Ehrlich introduced Salvarsan, an arsenical compound for the treatment of syphilis. This was the first chemotherapeutic synthetic agent to be effective against an infection. Moralists greeted this discovery with dismay since the punishment for sin would lose its sting. And the National Council for Combating Venereal Diseases went a step further and opposed even prophylactic education. Champneys feared that widespread publicity about the prevention and available treatment of venereal dis- eases would throw the nation into a perpetual orgy. Instead of 40-60 weekly injections of the arsenicals, the penicillin cure took only eight days, causing further worries for the moral crusaders. This book was a translation of the French Catholic publication Cahier Laennec, and one chapter dealt with the medical and psychological sequelae of masturbation among boys; it was written by Professor J G Prick! In the 1930s, the United States Public Health Service embarked on an infamous experiment which was only termin- ated in 1970 amidst scandalous revelations. Four hundred poor blacks from Tuskegee, Alabama, who were infected with syphilis, were left untreated until they died in order to 150 study the natural history of the disease. How could a country which saw itself as pure and clean be visited by such a calamity? In a public survey in 1987,29 per cent of Americans thought that persons testing positive should be tattooed to make them readily recognisable. Various forms of mandatory screening were introduced by employers, immi- gration officials, insurance companies, and in schools and prisons. Similar atti- tudes have been reported in relation to denying treatment to smokers. As healthism is driven by a thirst for power rather than by concern for the welfare of fellow men, it is devoid of any moral principles. The installation of hidden cameras in every office, ward and corridor, with a central monitor in the personnel office, manned 24 hours a day by experts on sexual harassment? In an artificial atmosphere of suspicion and fear, created by feminists who see all men as potential sexual harassers, rapists and child abusers, the nuclear family is under attack. During this process large numbers of children were diagnosed as having been abused and many were taken from their homes and placed in council care. No medical tests are perfect, but the value of reflex anal dilatation is open to severe doubt. In fact, by their own admission, Hobbs and Wynne found the test posi- 159 tive in only 43 per cent of sodomised children, and it was two years later, in 1989, before data on the prevalence of reflex anal dilatation in normal children became available. A simple calculation reveals the full horror of using this test for incriminating fathers for sodomising their own children. Stanton and Sunderland suggested that less than one per cent of children are in fact sodomised. With this assumption, the application of the reflex anal dilatation test to 10,000 children would turn out 43 true positives among 100 (one per cent) anally raped and 1,386 (14 per cent of the remaining 9,900 normal children) false positives. Words cannot describe the suffering of countless families falsely accused of an unspeakable crime. In the aftermath of the child abuse hysteria, convenient scapegoats were found, but without the central issue of who was stirring up the mass hysteria about child abuse and, more recently, Satanic child abuse, being addressed. In 1991 a four- year-old girl was threatened with being taken into care because she had an allergic reaction to cow-parsley sap. Both she and her brother developed skin blisters after they had been shooting dried peas at each other, with their father, through makeshift pea-shooters made from cow-parsley stems. The family was not believed and social workers ordered the girl to be kept in the Royal London Trust Hospi- 161 tal for three days. The 110 Lifestylism denials of the accused, or of the child, are constructed as admission of guilt. The worst excesses of this kind have been perpetrated by social workers determined to prove the existence of wide- spread Satanic child abuse. Despite the lack of any police evidence in support of these claims, the panic has swept Britain from Kent through Nottingham, Cheshire, Lanca- shire and West Yorkshire to Strathclyde and the Orkneys. For various therapists, coun- sellors and specialists in Satanic child abuse, the scare has become a lucrative business. It keepeth and preserveth the head from whist- ling, the eyes from dazzling, the tongue from lisping, the mouth from maffling, the teeth from chattering, the throat from rattling, the hands from shivering, the sinews from shrinking, the veins from crumpling, the bones from 163 aching, and the marrow from soaking. The attitude of the medical profession towards alcohol has vacillated between approval of controlled use and outright condemnation. The death rate from cirrhosis of the liver among British doctors, as late as 1961, was 3. As George Bernard Shaw quipped, nobody seemed to notice that doctors die of the very diseases they profess to prevent or cure. Lunacy, vice and death were some of the consequences of unsupervised use of alcoholic beverages. Medical science had proofs: Professor of Therapeutics, Dr W Carter, found that seeds of any kind germinate better in water than in alcohol, ergo, alcohol was injurious to the vital- 165 ity of protoplasm, it killed life. A variant of this proof is the schoolboy joke about the teacher who demonstrated the baneful effect of alcohol on life by dropping a worm into a glass of water and another into a glass of whiskey. On the one side, moralists crusaded against the demon drink, while on the other side, doctors sought to retain their monopoly on the diagnosis, treatment and prevention of alco- 112 Lifestylism holism. In Ireland, between 1838 and 1841, Father Matthew, a charismatic crusader against alcohol, was reputed to have induced two million Irishmen to pledge total abstinence. The wording of the Pledge was as follows: For Thy greater glory and consolation, O Sacred Heart of Jesus, for Thy sake to give good example, to practise self-denial, to make reparations to Thee for the sins of intemperance and for the conversion of excessive drinkers, I will abstain for life from all intoxicating drinks. Dr C Graves, a dispensary doctor from Cookstown noted that on market days the atmosphere absolutely reeked of ether. Nazi public health officers argued that alcohol was far more dangerous 166 to health than morphine or cocaine, and alcoholics were candidates for sterilisation. The prohibitionist mentality was epitomised in a speech which the Alabama representative, Richmond P Hobson 168 gave in Congress in 1914. It displayed the whole spectrum of prohibitionist arguments ranging from pseudoscience to health fascism. It was a humane law, as the drinker as an individual was not coerced; it simply prohibited the manufacture and the sale of the poison. Alcohol was a protoplasmic poison that: lowers in a fearful way the standard of efficiency of the Nation, reducing enormously the national wealth, entailing startling burdens of taxation, encumbering the public with the care of crime, pauperism, and insanity; it corrupts poli- tics and public servants, corrupts the Government, cor- rupts the public morals, lowers terrifically the average standard of character of the citizenship, and undermines the liberties and institutions of the Nation; it undermines and blights the home and the family, checks education, attacks the young when they are entitled to protection, undermines the public health, slaughtering, killing, and wounding our citizens many fold times more than war, pestilence and famine combined; it blights the progeny of the Nation, flooding the land with a horde of degenerates; 114 Lifestylism it strikes deadly blows at the life of the Nation itself and at the very life of the race. There was a handful of libertarians, such as Clarence Darrow, H L Mencken, Walter Lippmann and Will Rogers, who were concerned that Prohibition was a threat to democracy and liberty, a smoke-screen for the imposition of a puritanical tyranny. A man may feel he has a right to drink, but certainly he has no inherent right to sell liquor. Some of the moral fervour behind the moves to criminalise alcohol consumption was only a hypo- critical posturing hiding the real motive for Prohibition, to increase the productivity of the working class.

When this adjustment is performed and observed intakes are thus more representative of the usual diet purchase antabuse 500 mg amex, the intake distribu- tion narrows trusted antabuse 500mg, giving a more precise estimate of the proportion of the group with usual intakes below requirements (Figure 13-2) 250 mg antabuse with mastercard. A statistical approach is then used to combine the information on nutrient intakes with the information on nutrient requirements in order to determine the apparent percent prevalence of nutrient inadequacy in the group purchase 250mg antabuse visa. The Probability Approach Using the probability approach requires knowledge of both the distri- bution of requirements and the distribution of usual intakes for the popu- lation of interest. This method assumes that the intake and requirement distributions are independent, an assump- tion that is not valid for the energy requirements addressed in this report because energy intakes are highly correlated to energy expenditure. The cut-point method further assumes that the variability of intakes among individuals within the group under study is at least as large as the variability of their requirements. This is thought to be true for all of the macronutrients discussed in this report. Dietary intake data are available from the 1994–1996 Continuing Survey of Food Intakes by Individuals. Esti- mated intakes are based on respondents’ intakes, which were adjusted to remove within-person variability using the Iowa State University method (Appendix Table E-2). Examination of the distribution of usual carbohydrate intake reveals that intakes at the 1st and 5th percentiles are 87 and 118 g/day, respectively. Thus, fewer than 5 percent of women in this age group appear to have inadequate carbohydrate intakes. Currently, a method for adjusting intakes to compensate for underreporting by indi- viduals is not available, and much work is needed to develop an acceptable method. Conversely, underestimates of the prevalence of inadequacy could result if foods rich in the nutrient of interest were overreported. Comparison of Assessments Using the Probability Approach and Biochemical Assessment If requirement estimates are correct, dietary intake data are reliable estimates of true usual intake, and biochemical measures reflect the same functional criterion used to set the requirement of a nutrient for the same population, then the prevalence of apparently inadequate dietary intakes and biochemical deficiencies or indicators of inadequacy should be similar. Using the Recommended Dietary Allowance The Recommended Dietary Allowances are not useful in estimating the prevalence of inadequate intakes for groups. Human milk and formulas with the same nutrient composition as human milk (after adjustment for bioavailability) provide the appropriate levels of nutrients for full-term infants of healthy, well-nourished mothers. Groups of infants consuming formulas with lower levels of nutrients than that found in human milk may be at some risk of inadequacy, although the prevalence of inadequacy cannot be quantified. A distribution of usual intakes, including intakes from supplements, is required to assess the proportion of the popu- lation that might be at risk of over-consumption. If significant proportions of the population fall outside the range, concern could be heightened for possible adverse consequences. Appendix Table E-6 presents data on the usual daily intake of total fat as a percentage of energy intake and indi- cates that for all groups of children and adolescents, the 5th percentile of intake is at least 25 percent. Intakes at this level ensure that the risk to individuals of not meeting their requirements is very low (2 to 3 percent). Likewise, an infant formula with a nutrient profile similar to human milk (after adjustment for differences in bioavailability) should supply adequate nutrients for an infant. Using the Tolerable Upper Intake Level Tolerable Upper Intake Levels (Uls) were not set for the macronutrients covered in this report. The approach to planning for a low prevalence of inadequacy differs depending on whether or not the distributions of intake and requirements are normally distributed. Additional details are provided in the forth- coming Institute of Medicine report on dietary planning. For example, assume that the goal of planning was to target a 2 to 3 percent prevalence of inadequacy for a nutrient for which both require- ment and intake distributions were statistically normal. Preva- lence of inadequacy more or less than 2 to 3 percent could also be consid- ered. Finally, when it is known that requirements for a nutrient are not normally distributed and one wants to ensure a low group prevalence of inadequacy, it is necessary to examine both the intake and requirement distributions to determine a median intake at which the pro- portion of individuals with intakes below requirements is likely to be low. For example, a meal program for a university dormitory might be planned using the midpoint of the ranges for carbohydrate and fat (for adults, these would be 55 and 28 percent of energy, respectively). Using the univer- sity dormitory example, a dietary pattern might be planned in which the mean intake from fat was 30 percent of energy. Assessment conducted following implementation of the program might reveal that actual fat intakes of the students ranged from about 25 percent to about 35 percent of energy. In other words, the prevalence of intakes outside the acceptable range is low, despite a mean fat intake that is higher than the midpoint of the range. The approach to planning for energy, however, differs substantially from planning for other nutrients. There are adverse effects to individuals who consume energy above their requirements—over time, weight gain will occur. In all cases, however, the equations estimate the energy expen- diture associated with maintaining current body weight and activity level. They were not developed, for example, to lead to weight loss in overweight individuals. However, just as is the case with other nutrients, energy expen- ditures vary from one individual to another, even though their characteris- tics may be similar. Note that this does not imply that an indi- vidual would maintain energy balance at any intake within this range; it simply indicates how variable requirements could be among those with similar characteristics. Usual energy intakes are highly correlated with expenditure when con- sidered over periods of weeks or months. This means that most people who have access to enough food will, on average, consume amounts of energy very close to the amounts that they expend, and as a result, main- tain their weight over extended periods of time. Any changes in weight that do occur usually reflect small imbalances accumulated over a long period of time. In many situations, however, the usual energy intake of an indi- vidual is not known, and the estimated energy requirement equations are useful planning tools. When the goal is to maintain body weight in an individual with specified characteristics (age, height, weight, and activity level), an initial estimate for energy intake is provided by the equation for the energy expenditure of an individual with those characteristics. By definition, the estimate would be expected to underestimate the true energy expenditure 50 percent of the time and to overestimate it 50 percent of the time, leading to corresponding changes in body weight. This indicates that monitoring of body weight would be required when implementing intakes based on the equations that predict individual energy requirements. In some situa- tions the goal of planning might be to prevent weight loss in an individual with specified characteristics. This would lead to an intake that would be expected to exceed the actual energy expenditure of all but 2 to 3 percent of the individuals with similar characteristics. Using the above example for the 33-year-old, low-active woman, one would provide 2,028 + (2 × 160) kcal, or 2,348 kcal. This intake would prevent weight loss in almost all individuals with similar characteristics. Of course, this level of intake would lead to weight gain in most of these individuals. This would lead to an intake that would be expected to fall below the actual energy requirements of all but 2. Using the above example for the 33-year-old, low-active woman, the energy requirement would be 2,028 – (2 × 160) kcal, or 1,708 kcal. Of course, this level of intake would lead to weight loss in most of these individuals. Planning for Energy for Groups As is true for individuals, the underlying objective in planning the energy intake of a group is similar to planning intakes for other nutrients— to attain an acceptably low prevalence of inadequacy and of potential excess. The approach to planning for energy, however, differs substan- tially from planning for other nutrients. In the case of energy, however, there are adverse effects for the indi- viduals in the group whose intakes are above their requirements, as weight gain is bound to occur over time. In addition, the assumptions required to apply this method, as well as for the probability approach, do not hold for energy. Most notably, the methods assume that intakes are essentially uncorrelated with requirements. In the case of energy, however, intakes are very highly correlated with requirements.

Functional Fiber consists of isolated, nondigestible carbohydrates that have beneficial physiological effects in humans. For example, viscous fibers may delay the gastric emptying of ingested foods into the small intestine, result- ing in a sensation of fullness, which may contribute to weight con- trol. Delayed gastric emptying may also reduce postprandial blood glucose concentrations and potentially have a beneficial effect on insulin sensitivity. Viscous fibers can interfere with the absorption of dietary fat and cholesterol, as well as with the enterohepatic recirculation of cholesterol and bile acids, which may result in reduced blood cholesterol concentrations. Consumption of Dietary and certain Functional Fibers, particularly those that are poorly fermented, is known to improve fecal bulk and laxation and ameliorate constipation. The relationship of fiber intake to colon cancer is the subject of ongoing investigation and is currently unresolved. Some are based solely on one or more analytical methods for isolating fiber, while others are physiologically based. In Canada, how- ever, a formal definition has been in place that recognizes nondigestible food of plant origin—but not of animal origin—as fiber. As nutrition labeling becomes uniform throughout the world, it is recognized that a single definition of fiber may be needed. Furthermore, new products are being developed or isolated that behave like fiber, yet do not meet the traditional definitions of fiber, either analytically or physiologically. Without an accurate definition of fiber, compounds can be designed or isolated and concentrated using available methods without necessarily providing beneficial health effects, which most people consider to be an important attribute of fiber. Other compounds can be developed that are nondigestible and provide beneficial health effects, yet do not meet the current U. Based on the panel’s deliberations, consideration of public comments, and subsequent modifications, the following definitions have been developed: Dietary Fiber consists of nondigestible carbohydrates and lignin that are intrinsic and intact in plants. Functional Fiber consists of isolated, nondigestible carbohydrates that have beneficial physiological effects in humans. This two-pronged approach to define edible, nondigestible carbohydrates recognizes the diversity of carbohydrates in the human food supply that are not digested: plant cell wall and storage carbohydrates that predomi- nate in foods, carbohydrates contributed by animal foods, and isolated and low molecular weight carbohydrates that occur naturally or have been synthesized or otherwise manufactured. While it is not anticipated that the new defini- tions will significantly impact recommended levels of intake, information on both Dietary Fiber and Functional Fiber will more clearly delineate the source of fiber and the potential health benefits. Although sugars and sugar alcohols could potentially be categorized as Functional Fibers, for la- beling purposes they are not considered to be Functional Fibers because they fall under “sugars” and “sugar alcohols” on the food label. Distinguishing Features of Dietary Fiber Compared with Functional Fiber Dietary Fiber consists of nondigestible food plant carbohydrates and lignin in which the plant matrix is largely intact. Nondigestible means that the material is not digested and absorbed in the human small intestine. Nondigestible plant carbohydrates in foods are usually a mixture of polysaccharides that are integral components of the plant cell wall or intercellular structure. This definition recognizes that the three-dimensional plant matrix is respon- sible for some of the physicochemical properties attributed to Dietary Fiber. Fractions of plant foods are considered Dietary Fiber if the plant cells and their three-dimensional interrelationships remain largely intact. Another distinguish- ing feature of Dietary Fiber sources is that they contain other macronutrients (e. For example, cereal brans, which are obtained by grinding, are anatomical layers of the grain consisting of intact cells and substantial amounts of starch and protein; they would be categorized as Dietary Fiber sources. Examples of oligosaccharides that fall under the category of Dietary Fiber are those that are normally constituents of a Dietary Fiber source, such as raffinose, stachyose, and verbacose in legumes, and the low molecular weight fructans in foods, such as Jerusalem artichoke and onions. Functional Fiber consists of isolated or extracted nondigestible carbo- hydrates that have beneficial physiological effects in humans. Functional Fibers may be isolated or extracted using chemical, enzymatic, or aqueous steps. Synthetically manufactured or naturally occurring isolated oligosaccharides and manufactured resistant starch are included in this definition. Also included are those naturally occurring polysaccharides or oligosaccharides usually extracted from their plant source that have been modified (e. Although they have been inadequately studied, animal-derived carbohy- drates such as connective tissue are generally regarded as nondigestible. The fact that animal-derived carbohydrates are not of plant origin forms the basis for including animal-derived, nondigestible carbohydrates in the Functional Fiber category. Isolated, manufactured, or synthetic oligosaccharides of three or more degrees of polymerization are considered to be Functional Fiber.
