Safety & Contraindications
In general, agricultural selection breeds out some of the natural pesticides, such as resveratrol, which also have many interesting biological activities. The recent ACS book, Wine, Nutritional and Therapeutic Benefits, heaps praise on resveratrol, failing to tell us that there is 10–100 times more in the leaves, and I suspect seeds, than in the fruit pulp and wines. The seeds have only recently come to the market and clinical trials are few and far between. On the other hand, the fruits contain more than 30 types of anthocyanins. Small wonder that grapejuice has four times the ORAC score of any other fruit juice studied.
