Rainbow Diet: Blue and Purple

Mar 10, 2016 by

Blue and purple food have many overlapping food items and benefits so we decided to put them into one category. The food in this category is well known for their high level of anthocyanin, which gives them their deep dark pigment. These are one of the most potent antioxidants and provide many health benefits for the body.


There have been many studies conducted with the anthocyanin that induces its ability to prevent cancer and other diseases. These studies have shown that foods with this particular pigment could reduce esophagus cancer by 60%, and decrease cholesterol levels by 13.7%. It has also been shown to improve age induced short-term memory loss and prevents urinary tract infections like E.coli by keeping bacteria from sticking to cells within the body. Additionally, the food that contains this pigment has also shown to lower risk of metabolic syndrome, gum disease, and stomach ulcers while keeping the eyes healthy!


More specifically speaking, grape seed extracts have been shown to prevent atherosclerosis, gastric ulcer, cataracts, and diabetes while the grapes themselves have shown to be effective against heart and nerve diseases. Additionally, blueberries and blackberries have also shown to reduce risk for breast and colon cancer while being high in potassium, which counters high-salt diets and lowers blood pressure. Plums and figs contain a lot of vitamin A, calcium, magnesium, iron, potassium, vitamin c, and fiber. Even the herbs with this pigment such as lavender and purple basil have shown to have a lot of nutritional benefits such as helping blood circulation, insomnia, anxiety, migraines, and depression.


This color category consists of: blueberries, blackberries, grapes, plums, figs, raisins, eggplant, purple cabbage, juneberries, prunes, black olives, black currants, concord grapes, elderberries, purple asparagus, purple carrots, purple Belgian endive, purple fleshed potatoes, black salsify, purple peppers, lavender, and purple basil.


You can incorporate these into your smoothies, porridge, yogurt, or pudding. The eggplant can be especially delicious with tomato sauce; including it in your pastas, lasagnas, and ratatouille dishes would be a delightful addition to your meals. You could also make coleslaw with the purple cabbage instead of the green ones to add a splash of color to your meal.
