Diet programs

Di(2-ethylhexyl) phthalate was found in both the packaging and in a number of contacted foods sampled in a 1985-89 survey as part of the Canadian Health Protection Branch Total Diet Program. Low levels (65 lg/kg [L] average in beverages and 29 ig/kg average in foods) associated with the use of di(2-ethylhexyl) phthalate-plasticized cap or lid seals were found in a variety of glass-packaged foods. It was... 

Foods. The FDA has conducted limited analyses for the higher chlorinated CDDs (HxCDD, HpCDD, and OCDD) in market-basket samples collected from 1979 to 1984 under the FDA s Total Diet Program (Firestone et al. 1986). Food samples found to contain PCP residues >0.05 g/g (ppm) were analyzed for... 

A third diet sampling procedure is based on analysis of representative food items purchased locally and on food consumption statistics. The intake estimates are then calculated by multiplying the concentration estimate of each food by the respective consumption estimates per day or per year. This approach is used by EML in Sr in the diet program (Klusek, 1984), Argonne s Cs in the Chicago Foods Program (Karttunen, 1982), and the FDA s Total Diet Studies Program (Stroube and Jelinek, 1985). 

Example 1.—A classical problem of linear programming is the diet problem. Given minimal needs for vitamins, iron, calcium, phosphorous etc., which are present in known proportions in a variety of possible foods with given prices, it is desired to determine a diet from these foods that meets the minimal needs for the vitamins and other ingredients at the lowest cost. To illustrate with a simple example and hypothetical figures, denote three types of food by Flt F2, F3, and two types of dietary requirements, e.g., vitamins by A and B. The table...

The FDA pesticide residue monitoring program analyzes selected baby foods for endosulfan under its Total Diet Study. In the period 1991-1995, 29 incidences of detectable amounts of endosulfan were reported from analyses of 276 items purchased in 12 separate collections (FDA 1995).

Rice bran fiber has fructo-oligosaccharides - a pre-biotic that helps friendly bacteria to proliferate in the gastrointestinal environment and improves intestinal and colon health (Tomlin and Read, 1988). Recent studies in humans (Kahlon and Chow, 1997) have revealed that rice bran fiber not only normalizes bowel function, but also helps in conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and Crohn s disease, and lowers the lipid levels. Rice bran fiber has been shown to significantly reduce renal stones (Jahnen et al., 1992). It is a good source of fiber in weight loss programs and therapeutic fiber diets for diabetics and heart patients. Fiber diets prevent cancer of the colon and large bowel, control obesity and improve bowel function.

A large part of the US diet is made up of crops which originate outside the USA. Currently, a US tolerance achieved through the submission of data obtained from residue trials run exclusively within the USA permits the importation of commodities grown in Latin America or other countries. Within the past 5 years, the ERA has initiated programs to ensure that residue testing to achieve a US tolerance better reflects the climatic and cultural conditions under which the commodity is grown.

The Diabetes Prevention Program was a 3-year study that showed that lifestyle modifications, including exercise (30 minutes/day, 5 days/week) and moderate (5%-10%) weight loss, reduce the probability of developing DM by 58% in patients with pre-diabetes. Results from this study suggest that diet, exercise, and behavior modification are effective in preventing type 2 DM in high-risk patients.14... 

As part of its Radionuclides in Food Program, the FDA determined concentrations of radionuclides in their Total Diet Study, as well as food originating from the vicinity of nuclear reactors including raw vegetables, food crops (primarily fruits), fish, and milk. While not specifically analyzed for 241Am, concentrations of...
