In the hot summer, the staple food on people's table is no longer rice, noodles and steamed bread, and corn has become the most popular one. In fact, apart from the parts we often eat, the whiskers and stalks of corn and even the water for cooking corn have certain therapeutic value, so don't waste them.
corn protects the cardiovascular system. Chinese medicine believes that corn has the functions of invigorating spleen and promoting diuresis, regulating stomach and diuresis, which is very suitable for people with spleen deficiency. Modern nutrition also believes that corn contains a lot of nutrients. The cellulose content in fresh corn is 6-8 times that of polished rice and polished flour, which can reduce the concentration of cholesterol in blood and thus play a role in preventing cardiovascular and cerebrovascular diseases. At the same time, when eating corn, you need to chew hard, which can play a good exercise role in teeth and facial muscles, and can also promote saliva secretion, which is conducive to food digestion.
corn water prevents infection. It is a pity that people often pour out the corn water when they eat delicious corn. Corn water not only has the fragrance of corn, but also has good health care value. It has the functions of diuresis, anti-inflammation, prevention of urinary tract infection, removal of liver fire and so on, and summer is the high incidence season of urinary tract infection. Therefore, it is best to leave some corn stigma and two layers of green husk when cooking corn, which will have better taste and efficacy, and you can add a little sugar or rock sugar when drinking.
Stigma Maydis can reduce blood sugar. In addition to corn, corn stigma and corn stem core have good health care functions. Chinese medicine believes that corn must have good diuretic, antihypertensive, hypoglycemic and stomach-regulating effects. Diabetic patients can use 6 grams of corn stigma, 15 grams of Radix Rehmanniae, 15 grams of pollen, 15 grams of Rhizoma Dioscoreae, and 15 grams of Polygonatum odoratum. Corn stalks have a good antiperspirant effect. Those who have spontaneous sweating or night sweats can take 2-3 corn stalks, add 5-1 grams of wheat and decoct with water.
There are many benefits of eating corn regularly
When it comes to corn, almost everyone knows it. It is loved by diners because of its golden color, crystal clear and moist, but you may not be very clear about the benefits of eating corn to human body, right?
The embryo of corn seeds is very large, accounting for about 3% of the total volume and 1% ~ 14% of the total weight. 77% ~ 89% of the fat of corn grains is concentrated in the embryo, so corn embryos can be used to make oil. There are many kinds of vitamins in corn, and the content is also rich.
In recent years, more and more attention has been paid to corn at home and abroad. The medical function of corn has aroused great interest of scientists, especially its anticancer effect.
Glutathione, a special anticancer factor, is contained in corn, which can combine with many carcinogens in human body and make it lose carcinogenicity. After being digested and absorbed, carotene contained in corn can be transformed into vitamin A with physiological activity in the body, and vitamin A can prevent and delay precancerous lesions. According to epidemiological investigation results, the intake of vitamin A or carotene is inversely proportional to the incidence of tumors, and carotene can also prevent the occurrence of lung cancer, gastric cancer, esophageal cancer, bladder cancer and colon cancer. Vitamin E contained in corn is an important anti-aging and beauty substance. The cellulose rich in corn is a kind of carbohydrate that can't be absorbed by human body, which can reduce the concentration of carcinogens in human intestine and reduce the accumulation of toxins in intestine, so corn can reduce the incidence of colon cancer and rectal cancer. Pectin contained in cellulose can combine with carcinogens to make it harmless and excreted from human body; Lignin can increase the activity of macrophages phagocytizing bacteria and cancer cells in the body by 2 ~ 3 times, and can inhibit the occurrence of cancer.
In addition, corn also contains a lot of magnesium. Facts have proved that magnesium has remarkable anti-tumor and anti-cancer effects and plays a "universal controller" role for living cells.
It can be seen that corn plays an important role in maintaining the nutritional balance of human body and promoting health and longevity. With the continuous improvement of people's understanding of corn, corn has also become one of the hot foods in the world.
[ healthy diet] how to eat corn is the most nutritious?
Recently, a study by the German Nutrition and Health Care Association shows that corn has the highest nutritional value and health care function among all staple foods.
It can prevent heart disease and cancer
In this one-year study, experts compared the nutritional value and health care function of many staple foods such as corn, rice and flour.
The results show that the vitamin content in corn is very high, which is 5-1 times that of rice and flour.
At the same time, corn contains a lot of nutritional and health-care substances, which also surprises experts. Besides carbohydrates, protein, fat and carotene, corn also contains nutrients such as riboflavin and vitamins. These substances are of great benefit in preventing diseases such as heart disease and cancer.
The research also shows that the nutritional value of special corn is higher than that of ordinary corn. For example, the content of protein, vegetable oil and vitamins in sweet corn is 1-2 times higher than that in ordinary corn; The content of "life element" selenium is 8-1 times higher; Among 17 kinds of amino acids, 13 kinds are higher than ordinary corn. In addition, the moisture, active substances, vitamins and other nutrients of fresh corn are much higher than those of old corn, because the nutrient content of corn will drop rapidly during storage.
There are seven kinds of "anti-aging agents"
Professor Rahman, a famous German nutritionist in charge of this research, pointed out that among the more than 5 kinds of nutritional and health-care substances that have been proved to be the most effective today, corn contains seven kinds-calcium, glutathione, vitamins, magnesium, selenium, vitamin E and fatty acids.
It has been determined that every 1g of corn can provide nearly 3mg of calcium, which is almost the same as that contained in dairy products. Rich calcium can lower blood pressure. If you take 1 gram of calcium every day, your blood pressure will drop by 9% after 6 weeks. In addition, the carotene contained in corn can be converted into vitamin A after being absorbed by the human body, which has the function of preventing cancer; Plant cellulose can accelerate the discharge of carcinogens and other poisons; Natural vitamin E has the functions of promoting cell division, delaying aging, lowering serum cholesterol, preventing skin lesions, and alleviating arteriosclerosis and brain function decline. The researchers pointed out that the lutein and zeaxanthin contained in corn can resist eye aging. In addition, eating more corn can also inhibit the side effects of anticancer drugs on human body, stimulate brain cells and enhance people's brain power and memory.
eat corn in a different way
how to eat corn is the most nutritious? Professor Rahman suggested that cooked corn is better than raw corn. Although cooking made corn lose some vitamin C, it gained more nutritious antioxidants. Whether fried or boiled, corn will release more nutrients. At the same time, cooked corn also releases a phenolic compound lysine, which has certain curative effect on cancer and other diseases. After high-temperature cooking, the activity of corn anti-oxygen free radicals increased, and oxygen free radicals would cause oxidative damage to the body and increase the risk of disease.
Europeans have summed up many scientific ways to eat corn. There are three main ways: one is tortillas. It is said that mixing garlic powder, black pepper, celery, etc. into corn flour and blending with tomato soup can reduce cholesterol. The second is corn porridge. The third is to make soup and salad with corn kernels, which is delicious and nutritious. However, experts remind that once the storage period of corn has passed, it is easy to get damp and mildew and produce toxins. Therefore, everyone must be optimistic about the shelf life before buying canned corn in the store.
