Soy Protein Diet Increases Lipoprotein (A) Concentrations Compared with Casein Diet
It’s known that dietary substitution of soy protein for casein decreases LDL- and increases HDL-cholesterol levels. Danish researchers have now discovered, however, that soy protein appears to increase lipoprotein (a) levels, which suggests that use of soy protein might not be advisable in antiatherogenic diets.
NOTE: Folks, I don’t think we should be using soy products of any kind because the soy proteins have too many anti-metabolites,e.g. anti-thyroid, etc.
