CZY TY WIESZ, CO TO SĄ BADANIA??
WCIĄŻ NIE PODAŁEŚ KONKRETNYCH BADAŃ MÓWIĄCYCH O SZKODLIWOŚCI WEGE.
CIĄGLE PRZYTACZASZ MATERIAŁY NIE NA TEMAT!!
Poza tym zalecenia żywieniowe dla narodu amerykańskiego są:
1. Zaleceniami żywieniowymi, a
nie naukowymi badaniami i nie pokazują ŻADNYCH DANYCH
2.
Są bardzo, bardzo ostrożne, ze względu na naciski ogromnego lobby przemysłu mięsnego. Zalecenie, by Amerykanie zrezygnowali natychmiast z jedzenia mięsa jest równie nierealne, jak powiedzienie Amerykanom, żeby oddali całą broń palną, bo za pomocą broni palnej zabija się ludzi.
3. Pomino tego nawet uznają, że dieta wegetariańska spełnia wszystkie wymogi dotyczące zdrowego żywienia: "Some Americans eat vegetarian diets for reasons of culture, belief, or health.
Most vegetarians eat milk products and eggs, and as a group, these lacto-ovo-vegetarians enjoy excellent health. Vegetarian diets are consistent with the Dietary Guidelines for Americans and can meet Recommended Dietary Allowances for nutrients."
Ale jak już mówiłem, po co zajmować się czymś, co nie jest ani badaniem, ani nie jest obiektywne? Ano po nic...
Dużo lepsze i NAUKOWE są wyniki badań

Health implications of vegetarianism
Vegetarian diets low in fat or saturated fat have been used
successfully as part of comprehensive health programs to
reverse severe coronary artery disease (3,4).
Vegetarian
diets offer disease protection benefits because of their
lower saturated fat, cholesterol, and animal protein content
and often higher concentration of folate (which reduces
serum homocysteine levels) (5), antioxidants such as
vitamins C and E, carotenoids, and phytochemicals (6).
–Not only is
mortality from coronary artery disease lower
in vegetarians than in non-vegetarians (7), but vegetarian
diets have also been successful in arresting coronary
artery disease (8,9). Total serum cholesterol and low-
density lipoprotein cholesterol levels are usually lower in
vegetarians, but high-density lipoprotein cholesterol and
triglyceride levels vary depending on the type of vegetarian
diet followed (10).
Vegetarians tend to have a lower incidence of hypertension
than non-vegetarians (11). This effect appears to be
independent of both body weight and sodium intake. Type
2 diabetes mellitus is much less likely to be a cause of
death in vegetarians than non-vegetarians, perhaps
because of their higher intake of complex carbohydrates
and lower body mass index (12).
Incidence of lung and colorectal cancer is lower in
vegetarians than in non-vegetarians (2,13). Reduced
colorectal cancer risk is associated with increased
consumption of fiber, vegetables, and fruit (14,15). The
environment of the colon differs notably in vegetarians
compared with non-vegetarians in ways that could
favourably affect colon cancer risk (16,17). Lower breast
cancer rates have not been observed in Western
vegetarians, but cross-cultural data indicate that
breast
cancer rates are lower in populations that consume plant-
based diets (18). The lower estrogen levels in vegetarian
women may be protective (19).
A well-planned vegetarian diet may be useful in the
prevention and treatment of renal disease. Studies using
human being and animal models suggest that some plant
proteins may increase survival rates and decrease
proteinuria, glomerular filtration rate, renal blood flow, and
histologic renal damage compared with a non-vegetarian
diet (20,21)"

No i tyle. Kilka z tych badań czytałem w całości, inne w streszczeniach [niestety, żeby przeczytać całość z archiwów internetowych, często trzeba zapłacić za pomocą karty kredytowej] i są one rzetelne, wiarygodne i nie budzą one ożywionych dyskusji w świecie naukowym, tak jak wynik 2+2=4 nie budzi u matematyków ożywionych dyskusji.
