Isoflavones (especially genistein and daidzein) present in soy products have been reported to have cardio protective benefits including a reduction in LDL cholesterol. However, it is still controversial whether products containing isolated soy isoflavones have same effects as dietary intake of soy protein.

Question: Are Soy's basic inherent Nutritional benefits enough to warrant increased consumption?

Several theories on the effect of soy on blood cholesterol profiles have been proposed, these are increased thyroxin levels, decreased insulin: glucagon ratio and increased hepatic LDL-receptor activity in response to soy protein ingestion. Isoflavone globulin helps in cholesterol clearance by the liver; and isoflavone saponine helps in cholesterol excretion from the body. Studies have also shown that phytoestrogen helps increase HDL "good" cholesterol level and genistein acts as a tyrosine kinase inhibitor that decreases thrombosis (blood clotting) protecting against cardiovascular diseases such as heart disease and stroke.

Hello Nisha,

There are studies on effect of isolated soy isoflavones,howvever, nothing conclusive has come out regarding efficacy vis a vis dietary soy.Most of the studies are under this consensus that isoflavones do not appear to have favorable effects on serum lipid profile(as seen with dietary soy).So its still controversial and till then consuming soy protein would be better option.

Hello Kanika if the question raised is whether isolated soy isoflavones have same effects as dietary intake of soy protein, can we take it that soy per se should help either which way?
Thank you
