People Who Take Supplements are Less Healthy
Antioxidation vs. oxidation has been billed as a contest between good and evil. The battle takes place in cellular organelles called mitochondria, where the body converts food to energy, a process that requires oxygen and so is called oxidation. One consequence of oxidation is the generation of electron scavengers called free radicals (evil). Free radicals can damage DNA, cell membranes, and the lining of arteries; not surprisingly, they've been linked to aging, cancer, and heart disease. To ...People who eat lots of fruits and vegetables have lower incidence of cancer and other diseases, but people who take nutritional supplements meant containing high doses of the nutrients found in fruits in vegetables die at much higher rates.

Vestigial GLO Pseudogene
And the evolutionary prediction that we’ll find pseudogenes has been fulfilled—amply. Virtually every species harbors dead genes, many of them still active in its relatives. This implies that those genes were also active in a common ancestor, and were killed off in some descendants but not in others. Out of about 30,000 genes, for example, we humans carry more than 2,000 pseudogenes. Our genome—and that of other species— are truly well populated graveyards of dead genes. The most fam...Used to produce Vitamin C, alive in most mammals, but dead in humans, primates, and others.

Phytochemical Exposure Prevents Cancer in Mice
Williams’s experiments have shown that the offspring of mice who ingest a phytochemical derived from cruciferous vegetables like broccoli, cabbage, and brussels sprouts during pregnancy were much less likely to get cancer, even when exposed to a known carcinogen. The same is true of the offspring of mice who were given green tea during pregnancy. After they were weaned, the offspring in William’s experiments never encountered these protective chemicals again, yet their exposure during pre...Even when exposed to known carcinogens.
