Eating raw white carrots and carrots is good, can greatly supplement the human body people lack of vitamins, but the two eat together is not good? This is determined by the different characteristics of the two. Studies have shown that white radish has a good digestive effect, because it contains mustard oil and digestive role of amylase, lignin, which lignin is absorbed by the gastrointestinal tract can also stimulate the vitality of the macrophage to improve the body's immunity; white radish also contains a variety of enzymes, can eliminate carcinogens, to play the purpose of anticancer; white radish contains interferon-inducing agents can stimulate the gastrointestinal mucosa to produce The interferon inducer contained in white radish can stimulate the gastrointestinal mucosa to produce interferon, which can play the role of anti-viral infection and inhibit tumor cell proliferation. The above enzymes, lignin and interferon inducer are not heat-resistant, and will be destroyed at a high temperature of 70℃.　It can be seen, white radish to better play its digestive, anti-cancer therapeutic effect is best eaten raw. Carrots are the opposite, carrots are rich in β-carotene, which can be converted into vitamin A. Vitamin A and β-carotene have the ability to promote the production of light-sensitive pigments in the eye, and can prevent night blindness, strengthen the eye's ability to recognize color, but also improve eye fatigue and eye dryness. However, when carrots are eaten raw, more than 70% of the carotene cannot be absorbed. Researchers through a number of experiments show that the most scientific way to eat carrots are two: first, cut carrots into chunks seasoned with meat stewed together, preferably with a pressure cooker, which reduces the contact between carrots and air, so that the carotene preservation rate of up to 97%; second, carrots cut into slices, with a sufficient amount of cooking oil will be stir-fried and eaten, so that the absorption of carotene utilization rate of up to 90%.　It can be seen that the carrot, white carrot together with cold dishes or stewed together cooking methods, will lead to one of the carrot nutritional value of the reduction. In addition, this cooking method will also induce a "civil war", this is because the white radish in the vitamin C content is very high, and carrots contain a fight against vitamin C decomposition enzyme, can destroy the white radish in the vitamin C. The two meet, so that the white radish in the loss of vitamin C is heavy, and its nutritional value is naturally also greatly reduced.　We need to remind you that, although the white radish has a good digestive effect, but because of its cool nature, spleen and stomach cold people, chronic gastritis, gastric ulcer patients should not be eaten in large quantities. For women, the intake of carrots should be moderate, otherwise, menstrual disorders, infertility may come to the door. This is because long-term intake of excessive carotene will affect the ovaries of the luteinizing hormone synthesis, and some may even cause no menstruation, no ovulation, or menstrual disorders.
