As men are stronger than women, so they need to consume much more calories. What's more, the cholesterol metabolism of the men is often destroyed, so they are susceptible to hypertension, ischemic heart disease, stroke, myocardial infarction and other diseases. To this end, the American scholars have especially summed up five important nutrients necessary for men's health.
First, plant cellulose
The main function of plant cellulose is to accelerate the peristalsis of the intestines, lower cholesterol and certain bile salts, reduce the glucose and fatty acids in the blood, so it has the function of lowering the blood pressure. What's more, plant cellulose also can eliminate some carcinogenic substances, and avoid suffering from rectal cancer. It is suggested that men should take in 18 to 20 grams of plant cellulose every meal. The main foods which are rich in plant cellulose include wheat bran, whole wheat bread, cabbage, potato, carrot, apple and so on.
Second, vitamin A
Vitamin A can help improve the immunity of the body, prevent cancer, as well as protect the eyesight. An adult man needs to take in 1,000 micrograms of vitamin A every day. However, excessive consumption of vitamin A is harmful to human health. Foods such as liver, dairy products, fish, tomato, and carrot all contain high content of vitamin A.
Magnesium is helpful to regulate the activity of human heart, lower blood pressure, prevent heart disease, and improve the fertility of the men. Experts recommend that men should eat two bowls of milk and a banana at breakfast, so as to provide enough magnesium to the body. Foods which contain plenty of magnesium are soybean, baked potato, walnut kernel, oatmeal and seafood.
Zinc can guarantee the sexual function of the men, and treat impotence. In addition, it can also improve the resistance against diseases of the body. However, the daily amount of zinc must not exceed 15 micrograms, because overdose of zinc will affect the function of other minerals in the body. Every 120 grams of lean meat contain 5 to 7 micrograms of zinc. What's more, turkey, sea products, and soybean are also rich in zinc.
Chromium can help promote the metabolism of cholesterol, and enhance the endurance of the body. In addition, under certain physical conditions, it can also promote the formation of muscle and avoid the accumulation of excessive fat in the body. A middle-aged man needs at least 50 micrograms of chromium every day. It is difficult to take in such a large amount of chromium only from food, so it is suggested that men should take some pharmaceutical preparations containing chromium, such as multi-vitamins and minerals.
