| Here is an interesting article , it's not exactly promoting vegan diet, but it promotes more fruits and vegetables in diet and with some animal rights promotion can help turn many people to veganism. Here is a tiny part that I found interesting and important, but I recomed reading the whole article. "Also, people don’t eat nutrients, they eat foods, and foods can behave very differently than the nutrients they contain. Researchers have long believed, based on epidemiological comparisons of different populations, that a diet high in fruits and vegetables confers some protection against cancer. So naturally they ask, What nutrients in those plant foods are responsible for that effect? One hypothesis is that the antioxidants in fresh produce — compounds like beta carotene, lycopene, vitamin E, etc. — are the X factor. It makes good sense: these molecules (which plants produce to protect themselves from the highly reactive oxygen atoms produced in photosynthesis) vanquish the free radicals in our bodies, which can damage DNA and initiate cancers. At least that’s how it seems to work in the test tube. Yet as soon as you remove these useful molecules from the context of the whole foods they’re found in, as we’ve done in creating antioxidant supplements, they don’t work at all. Indeed, in the case of beta carotene ingested as a supplement, scientists have discovered that it actually increases the risk of certain cancers. Big oops." |
