A food and health expert says that blue and purple foods can prevent blood mass formation, and they also lower the risk of cancer.

　　Foods that contain blue and purple colors are: reddish eggplant(especially the skin), blueberries, blackberries, purple grapes, etc. .

　　Green

　　We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer. Dr. Ashok Agarwal, a food and nutrition specialist, explains, “They are excellent sources of folic acid, Vitamin K, as well as carotene(胡萝卜素). Diets high in those above are associated with lowered blood pressure. ”

　　Foods that contain the green color are: broccoli, cabbage, cucumbers, etc. .

　　Red

　　Lycopene(番茄红素)in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks.

　　Dr. Smiths says, “Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from foods depends on proper selection, storage and cooking of the produce. ”

　　Foods that contain the red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc. .
