1, Bitter Melon Bitter Melon has won people's special love for its bitter taste. The nutritional and health care characteristics of bitter gourd are as follows: First, it contains more vitamin C, vitamin B 1 and alkaloids; Secondly, it contains more galacturonic acid and pectin. Bitter taste in bitter gourd comes from quinine in alkaloid. These nutrients have the effects of stimulating appetite, promoting diuresis, promoting blood circulation, diminishing inflammation, reducing fever and refreshing the brain. Modern scientific research has found that the "polypeptide -P" substance in bitter gourd is an insulin-like substance, which has the function of lowering blood sugar. Xi An Medical University extracted insulin from bitter gourd for export. American scientists also found that bitter gourd contains a kind of protein and lipids, which can stimulate and enhance the ability of immune cells in animals to phagocytize cancer cells, and it can play an anti-cancer role in vivo together with quinine in alkaloids. Although bitter, bitter gourd tastes bitter and cold, refreshing and not greasy. It is refreshing and comfortable to eat in summer, and has the effect of clearing the heart and appetizing. Moreover, the bitterness will not be passed on to "others", such as bitter gourd burning fish and stewed fish, and the fish pieces will never have bitterness. Therefore, bitter gourd is also known as the "gentleman in the dish". If bitter gourd is made into herbal tea to drink in summer, it can make people feel refreshed and quench their thirst in summer. In some areas, bitter gourd is cut and slightly salted to reduce some bitterness and eaten as a vegetable; Some cut bitter gourd into rings and stew it with minced meat, garlic and lobster sauce to make it delicious. Hakka Shoushan sang: "People say bitter gourd is bitter, but I say bitter gourd is sweet. You can choose whether it is bitter or not. How can it be sweet without suffering? " In other words, bitter gourd itself is bitter, but it brings sweetness-health and happiness. 2, tomatoes It is said that hundreds of years ago, tomatoes were still unknown. Later, there was a girl in Peru, suffering from anemia and lovelorn. She wanted to eat a poisonous plant, but her face turned red after she swallowed the tomato fruit. If she eats it again, it will be even more rosy. Instead of dying, she recovered and became more beautiful. What is the reason? Originally, tomato fruit is rich in protein, fat, carbohydrate, gibberellic acid, carotene, vitamin B 1, B2, C and so on. Among them, the content of vitamin C for beauty is equivalent to 10 times that of watermelon, which is simply a vitamin warehouse. It also contains minerals such as calcium, phosphorus and iron that promote the growth and development of teenagers, and lycopene that inhibits the growth of bacteria. With all this, it is strange that Peruvian girls are unhealthy and not beautiful! 3. Pumpkins In the era of food shortage, pumpkins once played a great role as a kind of food, but why are pumpkins so popular in today's well-off society? There are three reasons: first, pumpkin is sweet and delicious; Second, pumpkin is rich in vitamin A, which can strengthen mucous membrane, prevent colds, prevent rough skin at the same time, have the effect of beauty and fitness, and also prevent keratoxerosis and night blindness. Modern medicine has found that pumpkin contains trace elements such as cobalt, zinc, copper and pectin, which can promote the normal secretion of human insulin. Therefore, pumpkin can effectively prevent and treat diabetes, hypertension, liver and kidney diseases, enhance anti-anemia and anti-cancer ability, eliminate bacterial toxicity in vivo, reduce the risk of colon cancer, and prevent and treat atherosclerosis. Carrot, also known as yellow radish, is a good vegetable with rich nutrition and suitable for all ages, and is known as "Little Ginseng". The most famous component in carrots is carotene, which is a yellow pigment. 100 years ago was first found in carrots. It is now known that carrots contain carotene1.35-17.25mg per 100g, which is far more than other vegetables, 360 times that of potatoes and 36 times that of celery. Carotene can be converted into vitamin A after it enters the human body and is absorbed, so it is also called provitamin A. What is valuable is that although carrots are cooked and steamed in the sun, the loss of carotene is very small. Eating carrots regularly has many benefits to the body: First, it can enhance immunity, resist cancer and prevent glass. For example, the lack of vitamin A in the human body not only has a great impact on the eyes and skin, but also has poor resistance and is prone to respiratory and urinary diseases. If you eat carrots regularly to meet the human body's demand for vitamin A, it can not only nourish the eyes and mucous membranes, but also enhance the human body's disease resistance. In addition, carrots contain a lot of lignin, which can also improve the body's disease resistance. According to the observation of British and American cancer research institutions for more than 20 years, people who often eat foods rich in vitamin A, such as carrots, are 40% less likely to develop lung cancer than those who don't often eat such foods. The second is beauty and fitness. Another function of vitamin A is to maintain the normal function of human epithelial tissue and make it secrete glycoprotein to keep the skin moist and tender, so eating carrots often can keep a radiant young image. In addition, carrots contain mustard oil and amylase, which can promote the metabolism of fat, prevent excessive fat from accumulating under the skin and getting fat, and keep fit. So Americans think carrots are beauty dishes, which can nourish hair, skin and mucous membranes. Now Europeans often eat carrot cakes, and even Russians eat carrot jiaozi. In China, there are also carrot drinks and carrot apple beauty juice, but generally carrots are fried, burned, stewed and boiled as vegetables.
