All about fruitarianism with a long-term fruitarian, Lena

Intestinal microbiota may contribute to the well-established link between high levels of red meat consumption and cardiovascular disease risk. 

The study tested the carnitine and trimethylamine-N-oxide (TMAO) levels - a metabolite the researchers previously linked in a 2011 study to the promotion of atherosclerosis in humans - of omnivores, vegans and vegetarians, and examined the clinical data of 2,595 patients undergoing elective cardiac evaluations. The research finds that a diet high in carnitine promotes the growth of the bacteria that metabolize carnitine, compounding the problem by producing even more of the artery-clogging TMAO. 

Stanley Hazen, M.D., Ph.D.:

Carnitine metabolism suggests a new way to help explain why a diet rich in red meat promotes atherosclerosis.

The bacteria living in our digestive tracts are dictated by our long-term dietary patterns. A diet high in carnitine actually shifts our gut microbe composition to those that like carnitine, making meat eaters even more susceptible to forming TMAO and its artery-clogging effects. Meanwhile, vegans and vegetarians have a significantly reduced capacity to synthesize TMAO from carnitine, which may explain the cardiovascular health benefits of these diets.

Carnitine is naturally occurring in red meats, including beef, venison, lamb, mutton, duck, and pork. It is also a dietary supplement available in pill form and a common ingredient in energy drinks

A sharp distinction between humans and “animals” is essential if we are to bend them to our will, make them work for us, wear them, eat them–without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeeling toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.

Fruits

In botany, a fruit is the seed-bearing structure in flowering plants (for example, cherries, berries, bean pods, corn kernels, tomatoes, grains). "Fruit" normally means the fleshy seed-associated structures of a plant that are sweet or sour, edible in the raw state (apples, grapes, lemons, strawberries, etc). 

Edible fruits have propagated with the movements of humans and animals in a symbiotic relationship as a means for seed dispersal and nutrition. Humans and many animals have become dependent on fruits as a source of food.
