If you want to really reduce your risk, lok into the details of the article and note what are the active ingredients in the beneificial foods.They are flavonoids (anthocyanins, flavonols and flavanones). Anthocyanin pigments and associated flavonoids have demonstrated ability to protect against a myriad of human diseases, are predominant in teas, honey, wines, fruits, vegetables, nuts, olive oil, cocoa, and cereals.
I just searched in Google for “foods highest in flavanoids” and Mr. Google returned the following:
Good sources of flavonoids include all citrus fruits, berries, ginkgo biloba, onions (particularly red onion, parsley, pulses, tea (especially white tea and green tea), red wine, seabuckthorn, and dark chocolate (with a cocoa content of seventy percent or greater).
In my top bars and powders I do not have pulses or red wine. The rest of the list are in my ingredients list.
