Soy protein, thyroid regulation and cholesterol metabolism.

摘要: The effects of dietary protein on plasma cholesterol concentrations are well documented: animal proteins (casein) hypercholesterolemic compared with plant (soy protein). Although this effect source has been shown in many species, the mechanism is not completely understood. This paper reviews relationship between and thyroxine concentration. basic premise that feeding soy lowers concentration by causing an increase concentrations. metabolic changes involving occur when fed discussed. These consistent induced elevating thyroxine. Data presented from studies showing to laboratory animals consistently elevates Furthermore, elevation precedes change concentrations: a necessary requirement for hypothesizing causative effect. Possible mechanisms as how affects also presented.
