You must have heard the mantra “Eat the Rainbow”. While most of us consciously eat dark green and yellow / orange veggies and fruits are superstars, we tend to ignore purple / blue foods. However, it is a proven
fact that darker the coloration, higher the antioxidant level. So, reach out for those purple onions, concord grapes, purple cabbages, black figs, blackberries, blueberries, purple yams and the like!
The purple pigment in these foods contains various flavonoids, including resveratrol, which can help decrease blood pressure. Resveratrol also helps relax the arterial walls and decreases the pressure in the arteries, allowing for better circulation. These dark-colored foods also contain polyphenols that can reduce the inflammatory response in the body. Inflammation is often said to be the culprit in case of major diseases, including heart disease, diabetes, arthritis and immune dysfunction.
A Closer Look At Why Purple Foods are Awesome:
1. Purple foods could help fight cancer: In animal studies, resveratrol found in purple grapes, cranberries, blueberries, bilberries, and red wine and grape juice could inhibit the spread of colorectal cancer. Other promising studies show that the chemical induces cancer cell death in cases of prostate, breast, skin, liver, lung and blood cancers.
2. Purple foods heal your liver: Black rice, rich in anthocyanins, is a delicious antioxidant grain that has been found to reduce damage to the liver caused by excessive alcohol intake.
3. Purple foods are ulcer-fighters: A 2011 study on rats found that anthocyanins from blackberries reduced stomach ulcer formation. Researchers say this is because the antioxidants in blackberries prevent oxidation and boost the activity of other important antioxidants that are naturally present in the body.
4. Purple foods are good for the heart: Black currants are said to lower “bad” LDL cholesterol by up to 13 percent while raising “good” HDL cholesterol. Remember that wild raw berries have higher antioxidant content than their fresh raw berries or frozen counterparts.
5. Purple foods prevent UTIs: It is common knowledge that cranberries fight urinary tract infections. This is because of their anthocyanin content. This is the same amazing chemical found in vegetables such as purple cauliflower, purple carrots and purple cabbage, giving them UTI-fighting power as well. Studies show that anthocyanin compounds fight H. pylori, the bacteria that promotes stomach ulcers and urinary tract infections.
