Nutritional value of corn;
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 study, which lasted 1 year, experts compared the nutritional value and health care function of many staple foods such as corn, rice and wheat. The results show that the vitamin content in corn is very high, which is 5- 10 times that of rice and wheat.
At the same time, corn contains a lot of nutrients and health-care substances, which also surprised 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 selenium content of "life element" is 8- 10 times higher; Among 17 amino acids, 13 amino acids are higher than common corn.
In addition, the moisture, active substances, vitamins and other nutrients of fresh corn are much higher than those of old corn, because the cultivation branch of corn drops rapidly during storage. Professor Rahman, a famous German nutritionist in charge of this research, pointed out that among the more than 50 kinds of nutritional and health-care substances that have been proved to be the most effective today, corn contains 7 kinds-calcium, glutathione, vitamins, magnesium, selenium, vitamin E and fatty acids. It has been determined that every100g of corn can provide nearly 300 mg of calcium, which is almost the same as that contained in dairy products. Rich calcium can lower blood pressure. If you take 1 g 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, relieving arteriosclerosis and brain function decline.
The researchers pointed out that lutein and zeaxanthin contained in corn can fight against 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.
