Whether it's steamed corn in the traditional market, roasted corn in the night market, corn thick soup in fast-food western restaurants, or corn beard tea popular in Korea, corn is a very common delicacy. In fact, corn is not only delicious but also full. In fact, it also contains a lot of nutritional value, which can help to eliminate fatigue, prevent colds, improve acute nephritis, cystitis and urinary calculi, and prevent arteriosclerosis! Five health benefits of corn The origin of corn is the United States, and it has been planted since 3000 BC. It contains carbohydrates and many nutrients, and is the staple food in South America. The post-war food shortage era was also an important food source for Japan. Corn is not only full, but also rich in vitamins and nutritional value, which has many benefits for both eating and making tea. Duan Liyang Okada, a Japanese food researcher who eliminates fatigue, said that corn is rich in vitamin B 1, which can activate the enzyme activity that breaks down sugar. When vitamin B 1 is insufficient in the body, it will cause shoulder and neck pain, fatigue, anxiety, memory and attention loss. Especially after hard work and strenuous exercise, it is especially suitable to supplement vitamin B 1, which can effectively eliminate fatigue. Promoting metabolism Vitamin B2 is a nutrient that helps the body to metabolize, especially to maintain the health of the skin and mucous membrane, especially the mucous membrane is responsible for resisting the invasion of bacteria and viruses. Therefore, vitamin B2 supplementation helps to keep healthy and improve eye fatigue and congestion. When vitamin B2 is insufficient, it will cause stomatitis and skin inflammation. Corn stigma for improving acute nephritis, cystitis and urinary calculi contains nutrients such as citric acid, glucose, fatty acids and vitamin K. Dry corn stigma for 2-3 days, add 200~500ml of water to 5- 10g corn stigma every day, drink it three times a day after meals, and improve acute nephritis, cystitis and urinary calculi, and also eliminate edema. Prevention of arteriosclerosis The germ part of corn contains linoleic acid, which can reduce the cholesterol content in blood and prevent arteriosclerosis and stroke. Corn contains zeaxanthin and barley malt alkali, which has the same effect as vitamin A, and can protect the throat mucosa and prevent colds. The whole intestine laxative corn is rich in dietary fiber, especially the skin covering each fruit, which can be said to be a treasure house of dietary fiber, and the dietary fiber is as high as 4 times that of sweet potato. Because the dietary fiber of corn is insoluble dietary fiber, it will expand several times after absorbing water in the large intestine, which can increase the amount of feces and promote gastrointestinal peristalsis. With a proper amount of water-soluble dietary fiber components (such as kelp buds, kelp and avocado), constipation can be eliminated and the intestinal environment can be tidied up. Finishing the intestinal environment is helpful to expel toxins from the body, improve the skin condition and prevent colorectal cancer. The green leaves mean that the fresh corn kernels are arranged neatly and have a full appearance. Press the head and tail of corn to show that it is not fresh and avoid souring.
