Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life.
Blue/Purple
Blue is considered to be peaceful and calming and it has the same effect on our health. The blue/purple color in food is due primarily to their anthocyanins which are antioxidants(抗氧化剂)that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight.
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. .
Orange
The orange foods are also rich in carotene, which is a particularly good antioxidant. These foods are commonly considered eyesight foods because they contain Vitamin A. Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach. Foods that contain the orange color are: Carrots, mangoes, sweet potatoes, pumpkins, etc. .
