What is the optimum dose of wild blueberries to eat at a meal?



How to Convert Into an Equol Producer

Certain gut bacteria can supercharge the benefits of soy foods, resulting in even more bone protection, better control of menopausal symptoms, and lower prostate cancer risk, but how can we foster the growth of these good bacteria?



Culture Shock – Questioning the Efficacy and Safety of Probiotics

In certain medical conditions, probiotic supplements may actually make things worse.



How to Reduce Your TMAO Levels

Should we be concerned about high-choline plant foods, such as broccoli, producing the same toxic TMAO that results from eating high-choline animal foods, such as eggs?

I recommend people switch away from using rice milk.



How to Treat Heart Failure & Kidney Failure with Diet

One way a diet rich in animal-sourced foods like meat, eggs, and cheese may contribute to heart disease, stroke, kidney failure, and death is through the production of toxin called TMAO.
