In contrast erectile dysfunction remedies fruits buy genuine viagra vigour on-line, (gross) secondary school enrolment rates are a flow variable erectile dysfunction natural remedies over the counter herbs order genuine viagra vigour on line, indicative of gender differences in the particular year in which the data are measured erectile dysfunction medication nz quality 800 mg viagra vigour. This contrasts with previous studies that emphasize gender differences in literacy and primary school enrolment rates. First, substantial progress has been made in closing gender gaps in literacy and primary education, making it useful to shift focus to higher levels of education. Second, Humanity Divided: Confronting Inequality in Developing Countries 163 Gender inequality Figure 5. Trends in female and male average total years of education, 1990 and 2010 Panel A. Distributions of F/M ratios as economies change and move up the industrial ladder, secondary education is more likely than primary education to determine ability to participate in the paid economy rather than in earlier stages of economic development. With regard to the health domain, gender differences in life expectancy reveal information about physical well-being and duration of life. Although some studies also examine data on maternal mortality rates, this analysis maintains a focus on variables that explicitly measure gender gaps (Permanyer, 2013). Change in F/M ratio and initial F/M ratio total average years education Education this section examines total years of education of those 15 and older as a broad measure of educational achievement, using data from Barro and Lee (2010) for 1990 to 2010. It also examines gender differences in gross secondary enrolment rates for the same time period. This variable reflects the cumulative effect of educational inequality in a society. Panel A plots the distribution of the ratio of female-to-male (F/M) total years of education using a kernel density estimation procedure. As Panel A demonstrates, gender disparities in average total years of education have diminished over the past 20 years. The entire distribution has moved to the right, indicating that the average (at the country level) F/M ratio has risen. The share of countries with F/M ratios at or above 95 percent has risen from 33 percent in 1990 to 52 percent in 2010. Further, a large number of countries have achieved or are close to parity (countries are clustered around a value of 1, indicating equality in total years of education). At the other extreme, the percentage of countries in which the F/M ratio exceeds 1 has fallen. Overall, it is visually apparent that global gender inequality in total years of education is not only falling, but that we are moving toward global convergence with a large number of countries at or close to parity. Panel B plots the change in the F/M ratio of total years of education from 1990 to 2010 against the 1990 ratio. The negative correlation of these two variables shows that the greatest gains in narrowing educational gaps are countries that started out with the widest gaps. The two regions with the lowest F/M ratios in 1990 - the Africa and Arab regions - have made the largest advances toward gender equality in total educational attainment. The left tail has shifted to the right, indicating progress in the more unequal countries. Also, countries where the ratio had been greater than one in 1990 (in favour of females) have reverted to more gender equal outcomes (the right tail has shifted left). In fact, a large number of countries (almost 75 percent, compared to 60 percent in 1990) are now centred on a ratio of 1, indicating much greater global equality in secondary educational attainment. There is both greater gender equality in secondary school enrolment rates within countries and a global convergence of gender equality in secondary school enrolment rates of 0. This is good news and reflects solid progress as we move beyond parity in literacy and primary education. Panel B describes in more detail the unevenness with which countries at the lower end of the distribution have improved gender outcomes. It is noteworthy that cases of retrogression (declines in the F/M ratio) are concentrated among countries that started out with ratios close to or greater than 1 in 1990. As with total educational attainment, regional gains (shown in Panel C) are greatest for those that had the lowest ratios in 1990. Health outcomes Measurements of gender gaps in health should control for biological differences so as to isolate the effect of societal influences on gender inequality. Panel A presents the global distributions for each of these years and indicates a modest improvement in gender ratios at the low end of the distribution (the left tail moves right). The Humanity Divided: Confronting Inequality in Developing Countries 165 Gender inequality Figure 5. Regional trends in F/M secondary enrolment Note: 1990 and 2010 represent averages for 1989-91 and 2009-11, respectively. Regional trends in F/M life ratios expectancy, 1990 to 2010 Source: World Bank (2013). For instance, in 33 countries, the F/M life expectancy ratio was below 95 percent in 1990 and there was no decrease in that number by 2010. Panel B plots regional F/M life expectancy ratios for 1990 and 2010 to the change in the F/M ratio over the time period 1990 to 2010 (see the right axis). The greatest improvements are observable in the Arab region and in Asia and the Pacific, although these changes are very modest, with the ratio below gender parity even by 2010. Humanity Divided: Confronting Inequality in Developing Countries 167 Gender inequality In sum, the analysis shows mixed results with regard to global trends in gender equality in capabilities. Educational gaps are closing and there appears to be global convergence in gender educational equality. Results are less positive in the area of health, with life expectancy ratios making uneven progress and demonstrating greater global divergence. Gender trends in livelihoods Gender inequality in livelihoods can contribute to inequality in other domains (Collins et al. As such, women experience restricted ability to exercise their preferences in the gender division of unpaid/paid labour, the allocation of household income and their ability to exit harmful relationships. Numerous studies find that employment is a key mechanism for promoting gender equity and that gender equality in this domain can leverage change in other domains (Seguino, 2007; Ridgeway, 2011; Kabeer et al. Of course, it is not just access to employment or livelihoods, but also the relative quality of jobs that matters for economic empowerment. Segregation of women in low-wage insecure jobs will do little to improve their bargaining power if male household members have disproportionate control over good jobs. Wage data tend to be available primarily for higher-income countries and there is little globally comparable time-series data on the quality Results are less positive in the area and security of employment. Moreover, ownership and control over of health, with life expectancy assets influence bargaining power, but accurate time-series genderratios making uneven progress disaggregated measures of wealth and other assets are even less widely available than employment data. And, despite advances made and demonstrating greater global in measuring time use that could shed some light on the household divergence.

The extent to erectile dysfunction medication cheap viagra vigour 800mg mastercard which these reductions in risk were due to herbal remedies erectile dysfunction causes best buy for viagra vigour n-3 fatty acids is uncertain erectile dysfunction differential diagnosis discount viagra vigour 800mg visa. This group also experienced a 20 percent reduction in all-cause mortality and a 45 percent reduction in sudden deaths compared with the control group. Vitamin E, in contrast to n-3 polyunsaturated fatty acids, had no beneficial effects on cardiovascular endpoints. A meta-analysis of 31 placebocontrolled trials estimated a mean reduction in systolic and diastolic blood pressure of 3. Furthermore, a statistically significant doseresponse effect occurred with the smallest reduction observed with intakes of less than 3 g/d and the largest reduction observed with intakes at 15 g/d. Because impaired heart rate variability is associated with increased arrhythmic events (Farrell et al. However, the beneficial effect was found only in men with low initial heart rate variability. Several studies have examined whether n-3 polyunsaturated fatty acids affect growth of adipose tissue. Parrish and colleagues (1990, 1991) found that rats given a high fat diet supplemented with fish oil had less fat in perirenal and epididymal fat pads and decreased adipocyte volumes compared with rats fed lard. Adipose tissue growth restriction appeared to be the result of limiting the amount of triacylglycerol in each adipose tissue cell rather than by limiting the number of cells. The researchers concluded that the rats supplemented with n-3 fatty acids demonstrated reduced oxidation of fat and increased carbohydrate utilization. Little data exist with respect to the specific effects of dietary n-3 polyunsaturated fatty acids on adiposity in humans; therefore, prevention of obesity cannot be considered an indicator at this time. While several studies have reported a negative relationship between polyunsaturated fatty acid intake and risk of diabetes (Colditz et al. A review of the epidemiological data on this association concluded that polyunsaturated fatty acids, and possibly longchain n-3 fatty acids, could be beneficial in reducing the risk of diabetes (Hu et al. Studies conducted in rodents have shown that administration of fish oil results in increased insulin sensitivity (Chicco et al. Substituting a proportion of the fat in a high fat diet with fish oil prevented the development of insulin resistance in rats (Storlien et al. Thus, animal evidence suggests that the fatty acid composition of the diet may be an important factor in the effect of dietary fat on insulin action. Whether a change of dietary fat composition will alter insulin sensitivity in humans remains an open question. Studies in humans have demonstrated a relationship between increased insulin sensitivity and the proportion of long-chain n-3 polyunsaturated fatty acids in skeletal muscle phospholipids (Borkman et al. Risk of Cancer Experimental evidence suggests several mechanisms in which n-3 polyunsaturated fatty acids may protect against cancer. Animal studies with n-3 fatty acid or fish-oil supplementation have shown inhibition of mammary carcinogenesis and tumor growth (Grammatikos et al. Across-country epidemiological studies have shown an inverse relationship between dietary fish intake and breast cancer incidence and mortality (Kaizer et al. Moreover, despite these results, most case-control and prospective studies have not reported a protective effect of fish consumption on breast cancer (Willett, 1997). Ecological studies have also shown inverse relationships between fish and fish oil intake and colorectal cancer (Caygill and Hill, 1995; Caygill et al. Results from case-control and prospective studies have been somewhat equivocal (Boutron et al. However, Willett and colleagues (1990) found that higher fish consumption was associated with less colon cancer in women. Risk of Nutrient Inadequacy Vegetable oils, such as soybean oil, flaxseed oil, and canola oil, contain high amounts of -linolenic acid. Low intakes of -linolenic acid can result in inadequate biosynthesis of the longer-chain n-3 polyunsaturated fatty acids, resulting in an excessive ratio of n-6 polyunsaturated fatty acids (see Chapter 8). High intakes of n-3 polyunsaturated fatty acids (-linolenic acid) can also result in inadequate biosynthesis of long chain n-6 polyunsaturated fatty acids that are important for prostaglandin and eicosanoid synthesis (see Chapter 8). Based on the median energy intake by the various age groups (Appendix Table E-1), it is estimated that approximately 0. Data from interventional studies to support the benefit of even higher intakes of -linolenic acid were not considered strong enough to justify establishing an upper boundary greater than 1. In the United States, saturated fatty acids provided 11 to 12 percent of energy in adult diets and 12. The intake of cholesterol by American adults ranges from less than 100 mg/d to just under 770 mg/d (Appendix Table E-15). It is important to recognize that lower intakes of saturated fatty acids and cholesterol are observed for vegetarians, especially vegans (Janelle and Barr, 1995; Shultz and Leklem, 1983). Because certain micronutrients, saturated fats, and cholesterol are consumed mainly through animal foods, it is possible that diets low in saturated fat and cholesterol are associated with low intakes of these micronutrients. When the micronutrient intakes of Seventh-day Adventist vegetarians and nonvegetarians were measured, there were no significant reductions in micronutrient intakes with the lower saturated fat (7. Similarly, the intakes of most micronutrients were not significantly lower for vegans, except for vitamin B12 (0. Analysis of nutritionally adequate menus indicates that there is a minimum amount of saturated fat that can be consumed so that sufficient levels of linoleic and -linolenic acid are consumed (as an example see Appendix Tables G-1 and G-2). Other than soy products that are high in n-6 and n-3 fatty acids, many vegetable-based fat sources are also high in saturated fatty acids, and these differences should be considered in planning menus. To minimize saturated fatty acid intake requires decreased intake of animal fats. Saturated fatty acids can be reduced by choosing lean cuts of meat, trimming away visible fat on meats, and eating smaller portions. The amount of butter that is added to foods can be minimized or replaced with vegetable oils or nonhydrogenated vegetable oil spreads. Vegetable oils, such as canola and safflower oil, can be used to replace more saturated oils such as coconut and palm oil. Such changes can reduce saturated fat intake without altering the intake of essential nutrients. A reduction in the frequency of intake or serving size of certain foods such as liver (375 mg/3 oz slice) and eggs (250 mg/egg) can help reduce the intake of cholesterol, as well as foods that contain eggs, such as cheesecake (170 mg/slice) and custard pie (170 mg/slice). There are a number of meats and dairy products that contain low amounts of cholesterol. Therefore, there are a variety of foods that are low in saturated fat and cholesterol and also abundant in essential nutrients such as iron, zinc, and calcium. Trans fatty acids are high in stick margarine and those foods containing vegetable shortenings that have been subjected to hydrogenation.

The middle or third lobe of the prostate being enlarged erectile dysfunction doctors baton rouge buy discount viagra vigour 800mg on-line, bends the prostatic part of the urethra upwards erectile dysfunction san francisco purchase line viagra vigour. But when either of the lateral lobes is enlarged impotence 21 year old buy viagra vigour with paypal, the urethra becomes bent towards the opposite side. The pelvic fascia may be now felt reflected from the inner surface of the levator ani muscle to the bladder at a level corresponding with the base of the prostate, and the neck of the bladder in front, and the vesiculae seminales, N N, laterally. In this manner the pelvic fascia serves to insulate the perinaeal space from the pelvic cavity. If the perinaeum were to be penetrated at a point midway between the bulb of the urethra and the anus, and to the depth of two inches straight backwards, the instrument would transfix the apex of the gland. Its left lobe lies directly under the middle of the line of incision which the lithotomist makes through the surface; a fibrous membrane forms a capsule for the gland, and renders its surface tough and unyielding, but its proper substance is friable, and may be lacerated or dilated with ease, after having partly incised its fibrous envelope. The prostate is separated from the pudic artery by the levator ani muscle, and from the artery of the bulb, by the deep perinaeal fascia and the muscular fibres enclosed between its two layers. The prostate being a median structure, is formed of two lobes, united at the median line. The bulbus urethrae being also a median structure, is occasionally found notched in the centre, and presenting a bifid appearance. When this operation is required to be performed, the situation of the prostate is first to be ascertained through the bowel; and at a distance of an inch behind the posterior border of the gland, precisely in the median line, the distended base of the bladder may be safely punctured. If the trocar pierce the bladder at this point, the seminal vessels converging to the prostate from either side, and the recto-vesical serous pouch behind, will escape being wounded. If the prostate happen to be much enlarged, the relative position of the neighbouring parts will be found disturbed, and in such case the bladder can be punctured above the pubes with greater ease and safety. In cases of impassable stricture, when extravasation of urine is threatened, or has already occurred, the urethra should be opened in the perinaeum behind the place where the stricture is situated, and this (in the present instance) certainly seems to be the more effectual measure, for at the same time that the stricture is divided, the contents of the bladder may be evacuated through the perinaeum. If the membranous part of the urethra be that where the stricture exists, a staff with a central groove is to be passed as far as the strictured part, and having ascertained the position of the instrument by the finger in the bowel, the perinaeum should be incised, at the middle line, between the bulb of the urethra and the anus. The urethra in this situation will be found to curve backwards at the depth of an inch or more from the surface. The point of the staff is now to be felt for, and the urethra is to be incised upon it. The bistoury is next to be carried backwards through the stricture till it enters that part of the urethra (usually dilated in such cases) which intervenes between the seat of obstruction and the neck of the bladder. The lateral operation of lithotomy is to be performed according to the above described anatomical relations of the parts concerned. The bowel being empty and the bladder moderately full, a staff with a groove in its left side is to be passed by the urethra into the bladder. The position and size of the prostate is next to be ascertained by the left fore-finger in the rectum. Having now explored the surface of the perinaeum in order to determine the situation of the left tuberosity and ischio-pubic ramus, in relation to the perinaeal middle line, the staff being held steadily against the symphysis pubis, the operator proceeds to divide the skin and superficial fascia on the left side of the perinaeum, commencing the incision on the left of the raphe about an inch in front of the anus, and carrying it downwards and outwards midway between the anus and ischiatic tuberosity, to a point below these parts. The left fore-finger is then to be passed along the incision for the purpose of parting the loose cellular tissue; and any of the more resisting structures, such as the transverse and levator ani muscles, are to be divided by the knife. Deep in the forepart of the wound, the position of the staff is now to be felt for, and the structures which cover the membranous portion of the urethra are to be cautiously divided. Recollecting now that the artery of the bulb passes anterior to the staff in the urethra on a level with the bulb, the vessel is to be avoided by inserting the point of the knife in the groove of the staff as far backwards-that is, as near the apex of the prostate-as possible. The point of the knife having been inserted in the groove of the staff, the bowel is then to be depressed by the left fore-finger; and now the knife, with its back to the staff, and its edge lateralized (towards the lower part of the left tuber ischii), is to be pushed steadily along the groove in the direction of the staff, and made to divide the membranous part of the urethra and the anterior two-thirds of the left lobe of the prostate. The gland must necessarily be divided to this extent if the part of the urethra which it surrounds be traversed by the knife. The greater this angle is, the greater the extent to which the gland will be incised. The knife being next withdrawn, the left fore-finger is to be passed through the opening into the bladder, and the parts are to be dilated by the finger as it proceeds, guided by the staff. The staff is now to be removed while the point of the finger is in the neck of the bladder, and the forceps is to be passed into the bladder along the finger as a guide. The calculus, now in the grip of the forceps, is to be extracted by a slow undulating motion. The general rules to be remembered and adopted in performing the operation of lithotomy are as follow:-1st, the incision through the skin and sub-cutaneous cellular membrane should be freely made, in order that the stone may be easily extracted and the urine have ready egress. The incision which (judging from the anatomical relations of the parts) appears to be best calculated to effect these objects, is one which would extend from a point an inch above the anus to a point in the posterior perinaeal space an inch or more below the anus. The wound thus made would depend in relation to the neck of the bladder; the important parts, vessels, &c. The pudic artery will not be endangered if the deeper parts be divided by the knife, with its edge directed downwards and outwards, while its point slides securely along the staff in the prostate. Liston observes, "is to avoid all interference with the reflexion of the ilio-vesical fascia from the sides of the pelvic cavity over the base of the gland and side of the bladder. If this natural boundary betwixt the external and internal cellular tissue is broken up, there is scarcely a possibility of preventing infiltration of the urine, which must almost certainly prove fatal. The prostate and other parts around the neck of the bladder are very elastic and yielding, so that without much solution of their continuity, and without the least laceration, the opening can be so dilated as to admit the fore-finger readily through the same wound; the forceps can be introduced upon this as a guide, and they can also be removed along with a stone of considerable dimensions, say from three to nearly five inches in circumference, in one direction, and from four to six in the largest. Syme are also advocates for limited incisions, extending no farther than a partial division of the prostate, the rest being effected by dilatation. Cooper, inclined them in favour of a rather free incision of the prostate and neck of the bladder proportioned to the size of the calculus, so that this may be extracted freely, without lacerating or contusing the parts, "and, " says the distinguished lithotomist Klein, "upon this basis rests the success of my operations; and hence I invariably make it a rule to let the incision be rather too large than too small, and never to dilate it with any blunt instrument when it happens to be too diminutive, but to enlarge it with a knife, introduced, if necessary, several times. Opinions of the highest authority being thus opposed, in reference to the question whether free or limited incisions in the neck of the bladder are followed respectively by the greater number of fatal or favourable results, and these being thought mainly to depend upon whether the pelvic fascia be opened or not, one need not hesitate to conclude, that since facts seem to be noticed in support of both modes of practice equally, the issue of the cases themselves must really be dependent upon other circumstances, such as the state of the constitution, the state of the bladder, and the relative position of the internal and external incisions. Brodie) are good subjects for the operation, and recover perhaps without a bad symptom, although the operation may have been very indifferently performed. Others may be truly said to be bad subjects, and die, even though the operation be performed in the most perfect manner. What is it that constitutes the essential difference between these two classes of cases? If he requires the perinaeum to be protruded and the urethra directed towards the place of the incision, he can effect this by depressing the handle of the instrument a little towards the right groin, taking care at the same time that the point is kept beyond the prostate in the interior of the bladder. Having examined the surgical relations of the bladder and adjacent structures, in reference to the lateral operation of lithotomy, it remains to reconsider these same parts as they are concerned in the bilateral operation and in catheterism. The bulb of the urethra and the lower end of the bowel are on the same plane comparatively superficial. The base of the bladder is still more deeply situated than the prostate; and hence it is that the end of the bowel is allowed to advance so near the pendent bulb, that those parts are in a great measure concealed by these. As the apex of the prostate lies an inch (more or less) deeper than the bulb, so the direction of the membranous urethra, which intervenes between the two, is according to the axis of the pelvic outlet; the prostatic end of the membranous urethra being deeper than the part near the bulb. The scalpel of the lithotomist, guided by the staff in this part of the urethra, is made to enter the neck of the bladder deeply in the same direction. On comparing the course of the pudic arteries with the median line, A A, we find that they are removed from it at a wider interval below than above; and also that where the vessels first enter the perinaeal space, winding around the spines of the ischia, they are much deeper in this situation (on a level with the base of the bladder) than they are when arrived opposite the bulb of the urethra. The transverse line B B, drawn in front of the anus from one tuber ischii to the other, is seen to divide the perinaeum into the anterior and posterior spaces, and to intersect at right angles the median line A A. In the same way the line B B divides transversely both pudic arteries, the front of the bowel, the base of the prostate, and the sides of the neck of the bladder.

Therefore testosterone associations with erectile dysfunction diabetes and the metabolic syndrome buy viagra vigour 800mg visa, when data are extremely limited or conflicting erectile dysfunction medications over the counter buy viagra vigour 800 mg low price, extra caution may be warranted in consuming levels significantly above that found in typical food-based diets erectile dysfunction treatment yahoo purchase 800mg viagra vigour amex. A growing body of evidence has shown that macronutrients, particularly fats and carbohydrate, play a role in the risk of chronic diseases. Although various guidelines have been established that suggest a maximal intake level of fat and fatty acids. Furthermore, because there may be factors other than diet that may contribute to chronic diseases, it is not possible to determine a defined level of intake at which chronic diseases may be prevented or may develop. If an individual consumes below or above this range, there is a potential for increasing the risk of chronic diseases shown to affect long-term health, as well as increasing the risk of insufficient intakes of essential nutrients. Conversely, interventional studies show that when fat intakes are high, many individuals gain additional weight. Furthermore, these ranges allow for sufficient intakes of essential nutrients, while keeping the intake of saturated fat at moderate levels. The upper boundary corresponds to the highest intakes from foods consumed by individuals in the United States and Canada. This maximal intake level is based on ensuring sufficient intakes of essential micronutrients that are, for the most part, present in relatively low amounts in foods and beverages that are major sources of added sugars in North American diets. Highest priority is thus given to studies that address the following research topics: long-term, doseresponse studies to help identify the requirement of individual macronutrients that are essential in the diet. It is recognized that it is not possible to identify a defined intake level of fat for maintaining health and decreasing risk of disease; however, it is recognized that further information is needed to identify acceptable ranges of intake for fat, as well as for protein and carbohydrate that are based on prevention of chronic diseases and maintaining health; studies to further understand the beneficial roles of Dietary and Functional Fibers in human health; studies during pregnancy designed to determine protein and energy needs; information on the form, frequency, intensity, and duration of exercise and physical activity that is successful in managing body weight in both children and adults; long-term studies on the role of glycemic response in preventing chronic diseases, such as diabetes and coronary heart disease, in healthy individuals, and; studies to investigate the levels at which adverse effects occur with chronic high intakes of specific macronutrients. For some nutrients, such as saturated fat and cholesterol, biochemical indicators of adverse effects can occur at very low intakes. Thus, more information is needed to ascertain defined levels of intakes at which onset of relevant health risks. A statement for health professionals from the Nutrition Committee, American Heart Association. This comprehensive effort is being undertaken by the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes of the Food and Nutrition Board, Institute of Medicine, the National Academies, in collaboration with Health Canada. See Appendix B for a description of the overall process, its origins, and other relevant issues that developed as a result of this new process. Establishment of these reference values requires that a criterion of nutritional adequacy be carefully chosen for each nutrient, and that the population for whom these values apply be carefully defined. A requirement is defined as the lowest continuing intake level of a nutrient that, for a specific indicator of adequacy, will maintain a defined level of nutriture in an individual. The median and average would be the same if the distribution of requirements followed a symmetrical distribution and would diverge if a distribution were skewed. This is equivalent to saying that randomly chosen individuals from the population would have a 50:50 chance of having their requirement met at this intake level. The specific approaches, which are provided in Chapters 5 through 10, differ since each nutrient has its own indicator(s) of adequacy, and different amounts and types of data are available for each. That publication uses the term basal requirement to indicate the level of intake needed to prevent pathologically relevant and clinically detectable signs of a dietary inadequacy. The term normative requirement indicates the level of intake sufficient to maintain a desirable body store, or reserve. Its applicability also depends on the accuracy of the form of the requirement distribution and the estimate of the variance of requirements for the nutrient in the population subgroup for which it is developed. For many of the macronutrients, there are few direct data on the requirements of children. Where factorial modeling is used to estimate the distribution of a requirement from the distributions of the individual components of the requirement (maintenance and growth), as was done in the case of protein and amino acid recommendations for children, it is necessary to add (termed convolve) the individual distributions. The goal may be different for infants consuming infant formula for which the bioavailability of a nutrient may be different from that in human milk. In general, the values are intended to cover the needs of nearly all apparently healthy individuals in a life stage group. Instead, the term is intended to connote a level of intake that can, with high probability, be tolerated biologically. This indicates the need for caution in consuming amounts greater than the recommended intake; it does not mean that high intake poses no potential risk of adverse effects. One criterion may be deemed the most appropriate to determine the risk that an individual will become deficient in the nutrient, whereas another may relate to reducing the risk of a chronic degenerative disease, such as certain neurodegenerative diseases, cardiovascular disease, cancer, diabetes mellitus, or age-related macular degeneration. Role in Health Unlike other nutrients, energy-yielding macronutrients can be used somewhat interchangeably (up to a point) to meet energy requirements of an individual. However, for the general classes of nutrients and some of their subunits, this was not always possible; the data do not support a specific number, but rather trends between intake and chronic disease identify a range. Given that energy needs vary with individuals, a specific number was not deemed appropriate to serve as the basis for developing diets that would be considered to decrease risk of disease, including chronic diseases, to the fullest extent possible. These are ranges of macronutrient intakes that are associated with reduced risk of chronic disease, while providing recommended intakes of other essential nutrients. Above or below these boundaries there is a potential for increasing the risk of chronic diseases shown to effect long-term health. The macronutrients and their role in health are discussed in Chapter 3, as well as in Chapters 5 through 11. The amount consumed may vary substantially from day-to-day without ill effects in most cases. Healthy subgroups of the population often have different requirements, so special attention has been given to the differences due to gender and age, and often separate reference intakes are estimated for specified subgroups. People with diseases that result in malabsorption syndrome or who are undergoing treatment such as hemo- or peritoneal dialysis may have increased requirements for some nutrients. Special guidance should be provided for those with greatly increased nutrient needs or for those with decreased needs such as energy due to disability or decreased mobility. Life Stage Groups the life stage groups described below were chosen while keeping in mind all the nutrients to be reviewed, not only those included in this report. Except for energy, the first 6-month interval was not subdivided further because intake is relatively constant during this time. That is, as infants grow, they ingest more food; however, on a body-weight basis their intake remains nearly the same. During the second 6 months of life, growth velocity slows, and thus daily nutrient needs on a body-weight basis may be less than those during the first 6 months of life. The extent to which intake of human milk may result in exceeding the actual requirements of the infant is not known, and ethics of human experimentation preclude testing the levels known to be potentially inadequate. It also supports the recommendation that exclusive human-milk feeding is the preferred method of feeding for normal, full-term infants for the first 4 to 6 months of life. In general, for this report, special consideration was not given to possible variations in physiological need during the first month after birth, or to the variations in intake of nutrients from human milk that result from differences in milk volume and nutrient concentration during early lactation. However, where warranted, information discussing specific changes in bioavailability or source of nutrients for use in developing formulations is included in the "Special Considerations" section of each chapter. It is assumed that infants will have adequate access to human milk and that they will consume increased volumes as needed to meet their requirements for maintenance and growth.
