Tomatoes are one of the most commonly consumed vegetables in our daily life. Most people only know that its vitamin content is rich, but what benefits it has in health, what kind of tomatoes have the highest nutrient content, and how to do it to maximize the preservation The nutrition is not clear to many people. The main nutrient in tomatoes is vitamins, of which the most important and most abundant is lycopene, one of the carotenoids. Tomato varieties, color, maturity, sweetness, and even the season of production are all important reasons for determining the content of lycopene. Yellow varieties of tomato lycopene content is very small, only 0.3 mg per 100 grams; red varieties of tomatoes are higher, generally containing 2-3 mg per 100 grams, the highest can reach 20 mg. In general, the redder the tomatoes, the higher the lycopene content. The content of lycopene is inversely related to the soluble sugar content in tomatoes, that is, the more unsweetened tomatoes, the higher the lycopene content. In addition, the lycopene content of summer-produced tomatoes is relatively high, which is mainly due to abundant sunlight in the summer and long duration of light, which will increase the content of lycopene greatly; and the content of lycopene in tomatoes grown in winter greenhouses. Relatively low. An adult who eats 100-200 grams of tomatoes a day can meet the body's need for lycopene. But many people like to eat raw tomatoes, which is not conducive to the absorption of lycopene, because it is a fat-soluble vitamin, after heating and cooking oil, it is more conducive to its health. Cover with a lid when cooking and add some vinegar to protect it from oxygen damage.
