Fill your plate with a rainbow. Red leaf lettuce opposed to green leaf lettuce; red onions opposed to white onions; red kale as opposed to green kale. Here are some examples of colors in fruits and vegetables by natural plant pigments: Green fruits and vegetables are colored by chlorophyll. They may also contain lutein which works with zeaxanthin to keep eyes healthy. Red fruits and vegetables are colored by tlycopene or anthocyanins. Blue/purple fruits and vegetables are colored by anthocyanins.which protect cells from damage. Orange/yellow fruits and vegetables are usually colored by carotenoids. White fruits and vegetables are colored by anthoxanthins." Some also contain health-promoting chemicals such as allicin, Often the peel of a fruit or vegetable is the most colorful (read nutritious) part, particularly where antioxidants are concerned. Michael Greger, MD, writes, "More and more diseases--Alzheimer's, cancer, heart disease--are being linked to what's called "oxidant stress" in the body, which is the tissue damage wreaked by free radicals in our diet and environment. To prevent these diseases we rely on the superheroes and heroines of the body, the antioxidants found predominantly in whole plant foods like fruits. Most studies measuring the antioxidant power in fruits, though, has only studied the pulp of the fruit. In the most comprehensive study of it's kind ever published, a recent study out of China measured the antioxidant power of the pulp, peel and seed fractions of 28 different
fruits." |

In a new study red cabbage was seen to reduce the build-up of certain plaques in the brain that could cause Alzheimer’s disease, the most common form of dementia. Although the mechanism of Alzheimers is not clear, more support is gathering for the build-up of plaque from amyloid deposits. The deposits are associated with an increase in brain cell damage and death from oxidative stress. It is against the oxidative stress that the anthocyanins and other cabbage polyphenols appear to offer protection. Scientists Ho Jin Heo and Chang Yong Lee of Cornell University tested the effect of red and white cabbage and found the antioxidant activity of red cabbages was about six to eight fold of white cabbages. The news come hot on the heels of a similar report in the Journal of the Science of Food and Agriculture (doi: 10.1002/jsfa.2409) from New Zealand researchers who looked at blackcurrant extracts and Alzehimer's. The protective effects of the currants were again linked to the high anthocyanin content, and the researchers concluded: “The phenolic extract of blackcurrant demonstrated the highest protective effect.” Additional information about organic food and organics.
