High-Antioxidant Diet May Improve Insulin Control

Source: The Globe and Mail (Summary by NIM)

Antioxidants are just about the hottest ticket in the health food industry these days. Consumers just can't seem to get enough of them, thanks to their cancer-fighting capabilities (and also the fact that they appear in some of the tastiest foods!). But now there's even more reason to enjoy a high-antioxidant diet - especially for people battling obesity, diabetes or metabolic syndrome.

A new study has uncovered another mechanism by which antioxidants are able to improve our health - by improving hormonal action, especially that of insulin, which helps control blood sugar levels. Obese individuals, by virtue of consuming a high-calorie diet which includes many pro-oxidants, could benefit from including a higher number of antioxidant-containing foods in their diets. The process of oxidation damages cells and tissues which leads to cancer and heart disease and also contributes to aging.

Antioxidants, including vitamins E and C, selenium and carotenoids, such as beta-carotene, are found in many brightly coloured fruits and veggies, as well as whole grains, nuts and seeds. Some good sources include blueberries, lemons, broccoli, sweet potatoes, tomatoes and sunflower seeds.
