Eating vegetarian food mainly means eating vegetables. Eating vegetables sounds like a common thing, but if you eat it unscientific, it will also have a negative impact on your health. So how to eat vegetables is scientific and healthy? More and more people eat vegetarian food, which is undoubtedly beneficial to prevent arteriosclerosis. But it is not a blessing to be vegetarian without paying attention to collocation. Modern discovery shows that absolute vegetarianism has at least four disadvantages: first, it lacks necessary cholesterol, and moderate cholesterol has anti-cancer effect; Second, insufficient intake of protein is a risk factor for digestive tract tumors; Third, insufficient riboflavin intake leads to vitamin deficiency; Fourth, it is seriously deficient in zinc, which is a very important trace element to ensure the sound immune function of the body, while general vegetables are deficient in zinc. Eat more fresh vegetables. If you buy fresh vegetables at home, you will slowly lose some vitamins. For example, when spinach is stored at 20℃ for 24 hours, the loss of vitamin C will reach 84%. So, eat as many fresh vegetables as possible. & gt& gt& gt Can vitamins and vegetables replace each other? Nutritious parts that should not be discarded, such as bean sprouts, are eaten by people who only eat the bean sprouts above and throw away the beans. In fact, there are 2-3 times more vitamin C in beans than in buds. Then squeeze out the vegetable juice when making jiaozi, and the vitamins will be lost by more than 70%. The correct way is to cut the vegetables, mix them with oil, and then add salt and seasoning, so that the cabbage won't produce soup. According to the determination of frying with strong fire, the loss of vitamin C in vegetables fried with strong fire is only 17%, and if they are braised again after frying, the loss of vitamin C in vegetables is 59%. Therefore, stir-fry should use strong fire, so that the fried dishes are not only delicious in color, but also less in nutritional loss. Adding a little vinegar when cooking is also beneficial to the preservation of vitamins. In order to save time, some people like to fry the dishes in advance, and then put them in a pot to eat together or eat them while they are hot next time. In fact, vitamin B 1 in vegetables will lose 25% in the process of heating up after frying. Stir-fried Chinese cabbage will lose 10% after 30 minutes, and lose 20% after 1 hour. You need soup to eat vegetables. Many people like vegetables but don't like soup. In fact, most vitamins are dissolved in vegetable soup when cooking. Take vitamin c as an example. When Chinese cabbage is cooked, 70% of vitamin C will be dissolved in vegetable soup. Boil fresh peas in water for 3 minutes, and 50% vitamin C is dissolved in the soup. When washing and cutting vegetables, if the vegetables are cut and washed, a lot of vitamins will be lost to the water. Some people don't eat fat in order to lose weight, but prefer to eat vegetables added to meat. The researchers found that water-rich vegetable cells are filled with air, while meat cells are filled with water, so vegetables are more likely to absorb oil, which is not conducive to losing weight after eating. The pollution of raw vegetables soaked in vegetables is pesticides and molds. Pesticide poisoning in vegetables is not uncommon, and it is also reported in newspapers. Vegetables are parasites of mold, most of which are insoluble in water, and some are safe even in boiling water. It can enter the surface of vegetables several millimeters deep. Therefore, vegetables must be washed and soaked in clear water, peeled and discarded, especially eaten raw, otherwise it will bring harm to the body.
