Serve Soy With Citrus

Vitamin C may boost the effectiveness of phytoestrogens found in soy.

I came across a cool study published in 2000 by researchers from University of Southern California that is yet another example of how different components between foods can work together for maximum health benefit in your body.

According to this new study, Vitamin C may boost the effectiveness of phytoestrogens (found in soy) to inhibit the oxidation of LDL "bad" cholesterol. (Oxidation of LDLs is thought to encourage atherosclerosis or fatty deposits in the arterials walls).

The reason why it makes sense that phyto or plant estrogens may help protect LDL cholesterol from hazardous oxidation is because the hormone estrogen has been demonstrated to inhibit the susceptibility of LDL to be oxidized and it is only when women have low levels of estrogen (post menopause) that their risk of heart disease mirrors men.

Researchers from the University of Southern California discovered, in test tube experiments using LDL isolated from adult blood samples, that increasing amounts of three phytoestrogens (genistein, daidzein and equol) inhibited LDL oxidation and that this protective effect was even more powerful when ascorbic acid (vitamin C) was present too. Genistein and daidzein are the isoflavones found in soy and soy products. So paring some soy with some citrus sounds like a partnership that can't miss.
