They have been persuaded by decades of public-health pronouncements, endorsed by the U.S. National Academy of Sciences and the National Institutes of Health, that claim people can get every nutrient they need from the food they eat. Popping vitamins "doesn't do you any good," sniffs Dr. Victor Herbert, a professor of medicine at New York City's Mount Sinai medical school. "We get all the vitamins we need in our diets. Taking supplements just gives you expensive urine...
...impact of scientific studies. Beginning in the 1970s, population surveys worldwide started to uncover a consistent link between diet and health. A diet rich in fruits and vegetables, for instance, became associated with a lowered incidence of cancer and heart disease. Researchers then turned to examining the data nutrient by nutrient, looking at minerals as well as vitamins, to see which are tied most closely with specific ailments. Low vitamin C intake appears to be associated with a higher risk of cancer, low levels of folic acid with a greater chance of birth defects, and high calcium consumption with...
...study reports that many types of plants tend to grow more quickly in a carbon dioxide-rich environment, but that these plants contain fewer nutrients than plants grown in a normal environment. Consequently, these nutrient deficient plants take longer to decompose, which in turn leaves fewer nutrients available in the ground for new plants in the spring...
...attempt to determine the effects of atmospheric carbon dioxide levels on the ecosystem, Bazzaz and Fajer also examined the reactions of various insect populations to such nutrient deficient plants...
They found that butterfly larvae, which were fed leaves from nutrient deficient plants, had a higher rate of mortality and a slower rate of growth. Since insects constitute an important link in the food chain, lower populations of insects may have a huge impact upon animals and humans, they said...
