I cut and pasted this from a health food article written by Nickey Pilkington. This is not the entire article, I simply hammered out the Iron and left out the unnessary Dross. Her writings are below and put into qoutes.
The reason why I find this interesting is because the Rainbow is an important symbol in the Troth of the Northern Way, and it does seem to be an excellent guide to a holistic nutrition that will lead to or maintain ones health and well being.
"Perhaps we can also use the rainbow as a health reminder. The colors of the rainbow can be a reminder of the colors of the fruits and vegetables that we should eat on a daily basis for optimum health.
The blue and purple of the rainbow can remind us to eat purple grapes, blueberries, blackberries, elderberries, and black currents. These contain anthocyanins, which can reduce the risks of cancer, heart attack, diabetic complications, age-related memory loss, and Alzheimer's disease. They can also help control high blood pressure.
Many of the dark purple foods contain phenolics, which may slow the effects of aging and are powerful antioxidants. This group includes prunes, plums, and raisins.
The green color in the rainbow can remind us to eat green peas, honeydew melons, kiwifruit, broccoli, green lettuces, kale, spinach, and leafy greens. These contain lutein, which helps maintain good vision and reduces the risks of macular degeneration and cataracts.
Another green group includes cabbage, broccoli, bok choy, Brussels sprouts, rutabaga, Swiss chard, cauliflower, watercress, and turnips. These contain indoles, which are good for reducing the risks of cancer and tumor growth in cancer patients.
The yellow orange colors of the rainbow can remind us of foods that contain bioflavonoids, which work with vitamin C to reduce the risk of heart attack and cancer. They also have powerful antioxidants that help maintain strong bones, healthy skin, and good vision. The foods in this group include tangerines, oranges, lemons, grapefruit, peaches, apricots, nectarines, papaya, pineapple, pears, yellow raisins, and yellow peppers.
The dark orange of the rainbow can remind us to eat pumpkin, apricots, peaches, carrots, sweet potatoes, mangoes, butternut squash, and cantaloupes. These contain beta-carotene, which can boost the immune system, is a powerful antioxidant, helps maintain good vision, and reduces the risks of heart attacks and cancer.
The red band of the rainbow can remind us to eat tomato based products, watermelon, pink grapefruit, and guava. These foods contain lycopene and can reduce the risk of breast, skin, and prostrate cancer. They also reduce the risk of heart attack.
Other good foods in the red band are red onion, kidney beans, raspberries, cherries, strawberries, beets, cranberries, red apples (with the skin), and red cabbage. These contain anthocyanins, which are powerful antioxidants. They can help control high blood pressure and can reduce the risks of cancer, Alzheimer's disease, heart attack, and diabetes complications.
A healthy goal is to eat at least five servings of fruits and vegetables every day. It would be good to try to include fruits and vegetables from the different colors of the rainbow. There are many other fruits and vegetables that are not listed here. Include as many of them as possible for added variety and even better health."
