Why should we eat a colorful diet? Does it really matter where the calories come from as long as we meet our calorie target? Read the blog on the colorful world of fruits and vegetables to learn why quality is as important as quantity.
While tracking your food intake on MyNetDiary, you are likely tuned into the food quantities you eat and the number of daily calories you consume. Yes, that is very smart for weight management. For optimal health, also consider the quality of the foods you choose to fit into your calorie goal. One simple approach is to aim for a diet that includes a colorful array of fruits and vegetables.
Think of antioxidants as the body's soldiers that fight the free radicals that attack healthy cells, causing disease and aging. Scientists have discovered thousands of antioxidants in foods. There is thought to be a complicated network of antioxidants in foods that interact in the body's cells. For example, some antioxidants act to regenerate others. Therefore, it is not advisable to rely on single substances, but rather, to include an array of them in foods.
As simple as it sounds, scientists have identified important disease-crushing antioxidants according to the color of a fruit or vegetable. Plant foods have been color-coded into seven categories: red, red/purple, orange, orange/yellow, green, and white/green. For example, beta-carotene, found in red, orange and yellow pigments, has being studied for the prevention of lung and prostate cancer. Lycopene, a cancer-fighting substance, is found in red pigment. Lutein, a substance found in green leafy vegetables, is selectively taken up into the eye for protection against macular degeneration.
Antioxidant supplements are not a great idea for several reasons. For one, extensive studies have not shown a reduced risk of developing chronic diseases when individuals took supplements. In fact, in some cases, subjects taking high dose supplements actually showed an increased disease risk, such as studies showing beta-carotene caused increased lung cancer risk. Another reason supplements are not advised is that at high doses, supplements may interact with medications. Bottom line: eat a wide variety of antioxidants in colorful, fresh foods to get the most benefit with the least risk.
