A powerful antioxidant should contain a complex of broad
spectrum flavonoid antioxidants and phenolic acids which are proven to slow down the aging process — not just the visible signs of aging, like fine lines and wrinkles, but the critical hidden oxidative stress damage that is linked to a host of age related degenerative diseases such as arthritis, cancer, heart disease, diabetes, cognitive function and strokes.
Alongside of these spotlight
flavonoids, however, it is probably the very broad
spectrum of
flavonoid antioxidants in kale that are largely responsible for kale's cancer - preventive and other benefits, owing to their ability to reduce oxidative stress.
