Evidence based on findings of a few studies which are suggestive, but are insufficient to establish an association between exposure and disease. 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 translating these goals into dietary guidelines, due consideration should be given to the process for setting up national dietary guidelines (5). Theneed toadjust salt iodization, dependingonobserved sodium intake and surveillance of iodine status of the population, should be recognized. 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 15%. 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). 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:. 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. However, the Consulta- tion considered that the studies showing no effect of free sugars on excess weight have limitations. 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).

Thirty-nine states have issued fish consumption advisories due to mercury contamination. Mercury is a toxic pollutant across most regulatory programs (air, water, hazardous waste & pollution prevention).

The broth and membrane used vary depending on the sample type for water or wastewater. Excessive turbidity in the sample will plug the membrane filter, causing poor bacteria recovery and slow filtration times.
