Some people praise litchi for its good health: eating it can cool the five internal organs, relieve lung qi, nourish true yin and rejuvenate children. However, some people think that litchi is a "tonic" fruit, and eating too much will make it "dry". If the body and mind are hot and dry, it is not suitable for eating. Litchi's theory of "tonifying fire" may be because litchi contains a lot of natural glucose, which has special effects on enriching blood and strengthening lung, and has special promotion effect on blood circulation and heat production. Therefore, the weak people who are always "hyperactive in liver fire" and "easy to overheat" eat more lychees, which may cause irritability.

But when the stool is abnormal, or it is hot and dry, it is necessary to stop eating. Eating too much litchi will lead to abdominal distension and frequent abdominal pain, which is also commonly known as "poisoning". "Poisoning" can be done by drinking litchi shell soup, or eating a few slices of fresh lemons, or drinking a cup of lemon tea, or by reducing swelling and relieving pain.

Fresh corn contains a lot of natural vitamin E, which has the functions of promoting cell division, delaying cell aging, lowering serum cholesterol, preventing skin lesions, relieving arteriosclerosis and brain function decline. Vitamin A in fresh corn also has some auxiliary preventive and therapeutic effects on common dry eye, tracheitis, dry skin and nerve paralysis in middle-aged and elderly people. Fresh corn is rich in lysine (rarely found in dry corn), which is an essential nutrient for human body. Studies have found that eating more fresh corn can also inhibit the side effects of anticancer drugs on the human body. 2. Fresh corn contains a lot of cellulose, and its content is 6~8 times that of polished rice and refined flour. Plant fiber can maintain the normal ratio of bile salts and cholesterol, thus reducing the deposition of cholesterol in the bile duct system and preventing the formation and occurrence of gallstones; Plant fiber can also combine with bile acids in the intestine to form nonabsorbable compounds, which can accelerate the excretion of bile acids and promote the degradation of cholesterol in the liver, thus reducing the concentration of cholesterol in the blood, and avoiding cardiovascular and cerebrovascular diseases such as hypertension, cerebral infarction and coronary heart disease caused by high cholesterol concentration in the blood (dyslipidemia), which are constantly deposited on the blood vessel wall, thickening the arterial wall and narrowing the lumen. Cellulose can also make the stool smooth. Foods containing more plant fiber can increase the volume of stool, stimulate the peristalsis of intestinal wall, make stool excreted faster and reduce the toxicity to intestinal wall. Therefore, eating corn regularly can prevent constipation, hemorrhoids and rectal cancer, and can also reduce the occurrence of gastrointestinal diseases. 3. Chewing hard when eating fresh corn can exercise teeth, promote saliva secretion and firm gums. If old people have bad teeth, they can make some fresh corn porridge to drink.
