Bibliografia

Ecco per voi una raccolta di studi scientifici a sostegno di molte cose scritte su questo Blog e sulle mie pagine Facebook e Twitter. Quando vi chiedono le fonti di qualcosa che state dicendo, potete venire su questa pagina, dove potreste trovare quello che fa al caso vostro e fare un bel copia e incolla. Questo post e' in costante aggiornamento, quindi tenetelo d'occhio! Potete dare un'occhiata anche alla mia raccolta di articoli pro-carne. E non dimenticate mai di chiedere anche voi le fonti quando siete nel bel mezzo di una discussione. E mi raccomando, devono essere scientifiche, cioe' devono essere pubblicate su PubMed. Tutto il resto e' fuffa.

Privarsi di proteine animali significa ridurre il quantitativo di zinco e vitamina B12. Per questo i vegani possono sviluppare patologie cardiache e vascolari.

Predisposizione all'ictus come conseguenza di un regime dietetico estremamente povero di grassi; in particolare di quelli saturi.
FONTE: "There is good reason to suspect that low-fat vegan diets tend to down-regulate systemic IGF-I activity; this effect would be expected to increase stroke risk in vegans. Furthermore, epidemiology suggests that low serum cholesterol, and possibly also a low dietary intake of saturated fat--both characteristic of those adopting low-fat vegan diets--may also increase stroke risk. "
"Colinearity between red meat intake and other dietary factors (e.g. Western lifestyle, high intake of refined sugars and alcohol, low intake of fruits, vegetables and fibre) and behavioural factors (e.g. low physical activity, high smoking prevalence, high body mass index) limit the ability to analytically isolate the independent effects of red meat consumption. Because of these factors, the currently available epidemiologic evidence is not sufficient to support an independent positive association between red meat consumption and colorectal cancer."

Vegetarians exhibit a wide diversity of dietary practices, often described by what is omitted from their diet. When a vegetarian diet is appropriately planned and includes fortified foods, it can be nutritionally adequate for adults and children and can promote health and lower the risk of major chronic diseases. The nutrients of concern in the diet of vegetarians include vitamin B(12), vitamin D, ω-3 fatty acids, calcium, iron, and zinc. Although a vegetarian diet can meet current recommendations for all of these nutrients, the use of supplements and fortified foods provides a useful shield against deficiency.

Dietary factors including ascorbic acid and an elusive factor in animal protein foods (meat; fish and poultry) enhance iron absorption; while phytic acid; soy protein; calcium and polyphenols inhibit iron absorption. However; the effects of these dietary factors on iron absorption do not necessarily translate into an association with iron status and iron stores (serum ferritin concentration). In cross-sectional studies; only meat intake has consistently (positively) been associated with higher serum ferritin concentrations.
