This work by the Harvard School of public health states that while small trails have indicated that the amount of vitamin C contained in a typical multivitamin and taken in the beginning of the development of a cold "might ease symptoms" however, for the "average person, there's no evidence that megadoses make a difference or that they prevent colds." (2009) It is related as well that studies examining Vitamin

For example, serum beta-carotene, retinol, and alpha-tocopherol levels rose in autumn months. Vitamin C serum concentrations were higher in the winter and spring. Male participants revealed higher serum retinol concentrations than females, although male and female respondents already differed in terms of age. Younger respondents did have higher levels of beta carotene. Smoking had a stronger effect on lowering serum levels of vitamin C and beta-carotene than on retinol. In

Whole Food-Based Supplementation vs. Fragmented Vitamin and Mineral Supplementation Americans' interest in nutrition has grown in proportion to their waistlines over the last 30 years or so. Further, as healthcare in general improves and the population ages, problems associated with old age which were relatively rare in the past (because few people lived to see their 80th birthday) have become increasingly common. This has also contributed to the growing interest in

Controlled experiments are those in which groups are separated into control and experimental. Neither group knows what they are receiving, so they may or may not be receiving a sugar pill or something else. The control group is essential for comparisons -- what happens in the control group often determines how the experimental data is interpreted (Scientific Control Group, 2008). A double blind experiment is one in which some of the

This put me far short of the mark. The matter is complicated by the fact that foods only list whole proteins in the nutrition facts. In third world countries where food is scarce and meat is at a premium, the primary fare is rice and beans, which combine to form a complete protein. The primary failing of the food pyramid is that the USDA was under pressure to communicate simply to

Any weight loss, say doctors, is good weight loss. If there is some minor contribution the medication gives to the whole process, then that's positive. If taken strictly according to instructions, at worst, diet pills are harmless for the most part. Effects of Dietary Supplements The FDA regulates dietary supplements only in that it is required to ensure their safety. A manufacturer is not required to register a supplement or have
