One "authority" lists the following in descending order according to their
"antioxidant" content. It is best to consider the value of things other
than just antioxidant content: like; amount of fiber and type of fiber,
phenols content, mineral content, recognized vitamin content, etc. There
are more than likely other things which are presently undiscovered which are
causing researchers to react so dramatically when they discover that foods
provided by nature cause marvelous results. Consider that serious
nutritional research is in its infancy and a lot remains to be discovered.
For now, may I suggest eating more fruits and vegetables of all kinds, both
raw and cooked, some nuts and grains, but restrict your caloric intake. My
fellow practitioner, a cardiologist, recommends to his patients: "If it
isn't a vegetable, fruit, nut or whole grain and tastes real good, spit it
out."
