veganism: According to the 1999 Meta-study, pescetarians had the lowest mortality rate. Vegetarians and people who ate meat only occasionally (like, a few times a month) had a slightly higher mortality rate. Vegans and people who ate meat regularly had the highest mortality rate. http://www.ajcn.org/content/70/3/516S.fu鈥?/a> You have to read it carefully. It is important to note how healthy the diet is and other lifestyle factors. A vegetarian who lives off Cheesy Poofs and Red Bull, plays WOW and chain smokes, and doesn't do any exercise is not going to live as long as an omnivore who eats whole foods, drinks a lot of water, and exercises regularly. Assuming that all other things are equal, a vegetarian is less likely to suffer from certain kinds of cancer and ischemic heart disease. There haven't been too many studies done on this, though. Here's a list. It's from a vegan organization, but they don't bend the facts. In fact, their conclusion is that according to the studies, a vegan diet is NOT necessarily the healthiest. Here you are: http://www.veganhealth.org/articles/dxra鈥?/a> One interesting thing to look at is the Seventh-Day Adventist study. Even eliminating alcohol and tobacco consumption (both prohibited by the religion), the vegetarians lived longer. (Note: The second link provides "Cliff's Notes" about a number of studies... definitely worth a look.)|||I would take it this question is if all diets are done correctly. I think we could all agree Any diet is not healthy if not done correctly. With that taken under consideration logic would tell someone that the diet with the most options to choose from would be the best. Thus an omnivores diet is the healthiest. If done correctly of course. After all, if you put people out in the wild and let them survive on their own, most if not all would have to eat an omnivores diet just to survive. Humans are omnivores. Its natural, its nature, its healthy.|||I personally believe veganism is the best.. Facts: Not eating animal products eliminates 40 diseases. The number one killer in America, LDO-Cholesterol, is only found in meat. Bacon contains nitrites which, once in the stomach, may form substances linked to cancer. Smoked foods also been implicated as having cancer-inducing potential. Anaemia, appendicitis, arthritis, breast cancer, cancer of the colon, cancer of the prostate, constipation, diabetes, gall stones, gout, high blood pressure, indigestion, obesity, piles, strokes and varicose veins are just some of the well known disorders which are more likely to affect meat eaters than vegetarians. Avoiding meat is one of the best and simplest ways to cut down your fat consumption. Add to those hazards the fact that if you eat meat you may be consuming hormones, drugs and other chemicals that have been fed to the animals before they were killed and you can see the extent of the danger. No one knows precisely what effect eating the hormones in meat is likely to have on your health. But the risk is there and I think it's a big one. Some farmers use tranquillisers to keep animals calm. Others routinely use antibiotics so that their animals do not develop infections. When you eat meat you are, inevitably, eating those drugs. In America, over half of all antibiotics are fed to animals and I don't think it is any coincidence that the percentage of staphylococci infections resistant to penicillin went up from 13% in 1960 to 91% in 1988. The healthiness of a vegetarian diet is perhaps shown most dramatically by the fact that lifelong vegetarians visit hospitals 22% less often than meat eaters - and for shorter stays! Vegetarians tend to be fitter than meat eaters - as well as healthier - and many of the world's most successful athletes (particularly those who specialise in endurance events) follow a strictly vegetarian diet. It is the fat in meat that does most harm - and which makes meat eating an even bigger health hazard than smoking - but don't think you can avoid the dangers simply by avoiding red meat because you cannot. If you want to eat a truly healthy diet then you must give up eating meat completely.|||my take is to cut the following out of your meals: junk foods, processed foods made with white flour and sugar, and anything else made with white flour and sugar. wikipedia, the free online encyclopedia has information on flexitarianism at http://en.wikipedia.org/wiki/Semi-vegeta鈥?/a> on vegetarianism at http://en.wikipedia.org/wiki/Vegetariani鈥?/a> and on veganism at http://en.wikipedia.org/wiki/Veganism you could use the one-phrase-a-search-idea on the internet with phrases such as: "quick and easy low carb recipes", "quick and easy vegetarian recipes", "quick and easy vegan recipes", and "raw vegan recipes"|||first off, vegans/vegetarianism are going to tell you they are healthiest. Their is no real proof the vegetarianism or veganism is any healthier then eating meat. If you eat healthy meat in the right amounts this in my opinion is what is best.|||Depends on the human. There isn't one magical diet that every human would thrive on! Micheal Pollan put it best: "Eat food. Mostly plants. Not too much" And: "Don't eat anything your grandmother wouldn't recognize as food"|||veganism|||A vegan diet is the healthiest.
