Non-starch polysaccharides (NSP) Wholegrain cereals, fruits and vegetables are the preferred sources of non-starch polysaccharides (NSP). The best definition of dietary fibre remains to be established, given the potential health benefits of resistant starch. The recommended intake of fruits and vegetables (see below) and consumption of wholegrain foods is likely to provide 20 g per day of nsp ( 25 g per day of total dietary fibre). Fruits and vegetables The benefit homework of fruits and vegetables cannot be ascribed to a single or mix of nutrients and bioactive substances. Therefore, this food category was included rather than the nutrients themselves. The category of tubers (i.e. Potatoes, cassava) should not be included in fruits and vegetables. Body mass index (BMI) The goal for body mass index (BMI) included in this report follows the recommendations made by the who expert Consultation on Obesity that met in 1997 ( 20 ). At the population level, the goal is for an adult median bmi of 21-23 kg/m2.
However, the consultation considered that the studies showing no effect of free sugars on excess weight have limitations. The carmen study (Carbohydrate ratio management in European National diets) was a multicentre, randomized trial that tested the effects on body weight and blood wallpaper lipids in overweight individuals of altering the ratio of fat to carbohydrate, as well as the ratio of simple to complex. A greater weight reduction was observed with the high complex carbohydrate diet relative to the simple carbohydrate one; the difference, however was not statistically significant ( 18 ). Nevertheless, an analysis of weight change and metabolic indices for those with metabolic syndrome revealed a clear benefit of replacing simple by complex carbohydrates ( 19 ). The consultation also examined the results of studies that found an inverse relationship between free sugars intakes and total fat intake. Many of these studies are methodologically inappropriate for determining the causes of excess weight gain, since the percentage of calories from fat will decrease as the percentage of calories from carbohydrates increases and vice versa. Furthermore, these analyses do not usually distinguish between free sugars in foods and free sugars in drinks. Thus, these analyses are not good predictors of the responses in energy intake to a selective reduction in free sugars intake.
Acute and short-term studies in human volunteers have demonstrated increased total energy intake when the energy density of the diet is increased, whether by free sugars or fat ( 9-11 ). Diets that are limited in free sugars have been shown to reduce total energy intake and induce weight loss ( 12, 13 ). Drinks that are rich in free sugars increase overall energy intake by reducing appetite control. There is thus less of a compensatory reduction of food intake after the consumption of high-sugars drinks than when additional foods of equivalent energy content are provided ( 11, 14-16 ). A recent randomized trial showed that when soft drinks rich in free sugars are consumed there is a higher energy intake and a progressive increase in body weight when compared with energy-free drinks that are artificially sweetened ( 17 ). Children with a high consumption of soft drinks rich in free sugars are more likely to be overweight and to gain excess weight ( 16 ). The consultation recognized that a population goal for free sugars of less than 10 of total energy is controversial.

D The suggested range should be seen in the light of the joint who/FAO/unu expert hard Consultation on Protein and Amino Acid Requirements in Human Nutrition, held in Geneva from 9 to ( 2 ). E salt should be iodized appropriately ( 6 ). The need to adjust salt iodization, depending on observed sodium intake and surveillance of iodine status of the population, should be recognized. F see page 58, under Non-starch polysaccharides. Total fat The recommendations for total fat are formulated to include countries where the usual fat intake is typically above 30 as well as those where the usual intake may be very low, for example less than. Total fat energy submit of at least 20 is consistent with good health.
Highly active groups with diets rich in vegetables, legumes, fruits and wholegrain cereals may, however, sustain a total fat intake of up to 35 without the risk of unhealthy weight gain. For countries where the usual fat intake is between 15 and 20 of energy, there is no direct evidence for men that raising fat intake to 20 will be beneficial ( 7, 8 ). For women of reproductive age at least 20 has been recommended by the joint fao/who expert Consultation on Fats and Oils in Human Nutrition that met in 1993 ( 3 ). Free sugars It is recognized that higher intakes of free sugars threaten the nutrient quality of diets by providing significant energy without specific nutrients. The consultation considered that restriction of free sugars was also likely to contribute to reducing the risk of unhealthy weight gain, noting that: Free sugars contribute to the overall energy density of diets. Free sugars promote a positive energy balance.
The population nutrient intake goals for consideration by national and regional bodies establishing dietary recommendations for the prevention of diet-related chronic diseases are presented in Table. These recommendations are expressed in numerical terms, rather than as increases or decreases in intakes of specific nutrients, because the desirable change will depend upon existing intakes in the particular population, and could be in either direction. In Table 6, attention is directed towards the energy-supplying macronutrients. This must not be taken to imply a lack of concern for the other nutrients. Rather, it is a recognition of the fact that previous reports issued by fao and who have provided limited guidance on the meaning of a balanced diet described in terms of the proportions of the various energy sources, and that there is an apparent consensus. This report therefore complements these existing reports on energy and nutrient requirements issued by fao and who ( 2-4 ).
In translating these goals into dietary guidelines, due consideration should be given to the process for setting up national dietary guidelines ( 5 ). Ranges of population nutrient intake goals.

Evidence based on non-epidemiological studies, such as clinical and laboratory investigations, is supportive. More trials are required to support the tentative associations, which should also be biologically plausible. Evidence based on findings of a few studies which are suggestive, plan but are insufficient to establish an association between exposure and disease. Limited or no evidence is available from randomized controlled trials. More well designed research is required to support the tentative associations. The strength of evidence linking dietary and lifestyle factors to the risk of developing obesity, type 2 diabetes, cvd, cancer, dental diseases, osteoporosis, graded according to the above categories, is summarized in tabular form, and attached to this report as an Annex. 5.1.3 A summary of population nutrient intake goals.
The available evidence is based on a substantial number of studies including prospective observational studies and where relevant, randomized controlled trials of sufficient size, duration and quality showing consistent effects. The association should be biologically plausible. Evidence based on epidemiological studies showing fairly consistent associations between exposure and disease, but where there are perceived shortcomings in the paper available evidence or some evidence to the contrary, which precludes a more definite judgement. Shortcomings in the evidence may be any of the following: insufficient duration of trials (or studies insufficient trials (or studies) available; inadequate sample sizes; incomplete follow-up. Laboratory evidence is usually supportive. Again, the association should be biologically plausible. Evidence based mainly on findings from case-control and cross-sectional studies. Insufficient randomized controlled trials, observational studies or non-randomized controlled trials are available.
evidence that the nutrient is required in the diet and hence low intakes should not give rise to concern. It would be of concern if a large proportion of values were outside the defined goals. 5.1.2 Strength of evidence, ideally the definition of an increased or a decreased risk should be based on a relationship that has been established by multiple randomized controlled trials of interventions on populations that are representative of the target of a recommendation, but this type. The recommended dietary/nutrition practice should modify the attributable risk of the undesirable exposure in that population. The following criteria are used to describe the strength of evidence in this report. They are based on the criteria used by the world Cancer Research Fund ( 1 but have been modified by the Expert Consultation to include the results of controlled trials where relevant and available. In addition, consistent evidence on community and environmental factors which lead to behaviour changes and thereby modify risks has been taken into account in categorizing risks. This applies particularly to the complex interaction between environmental factors that affect excess weight gain, a risk factor which the consultation recognized as contributing to many of the problems being considered. Evidence based on epidemiological studies showing consistent associations between exposure and disease, with little or no evidence to the contrary.

Population nutrient intake goals for preventing diet-related chronic diseases.1 overall goals.1.1 Background, population nutrient intake goals represent the population average intake that is judged to be consistent with the maintenance of health in a population. Health, in this context, is marked by a low prevalence of diet-related diseases in the population. Seldom is there a single best value for such a goal. Instead, consistent with the concept of a safe range of nutrient intakes for individuals, there is often a range of population averages that would be consistent with the maintenance of health.
