Beans, Beans, They’re Good for Your Heart

Legumes such as lentils, chickpeas, beans and split peas may reduce cholesterol so much that consumers may be able to get off their cholesterol-lowering statin drugs, but to profoundly alter heart disease risk we may have to more profoundly alter our diet.



What’s the Best Mouthwash?

There’s a cheap concoction one can make at home that safely wipes out cavity-forming bacteria on our teeth better than chlorhexidine mouthwash and also reduces their plaque-forming ability.

There is a receptor in our intestines activated by phytonutrients in cruciferous vegetables that boosts immune function (the aryl hydrocarbon [Ah] receptor).



BRCA Breast Cancer Genes and Soy

One reason why soy consumption is associated with improved survival and lower recurrence rates in breast cancer patients may be because soy phytonutrients appear to improve the expression of tumor-suppressing BRCA genes.
