Experts point out that, middle-aged men are at a life stage full of survival stresses. In order to gain the status and dignity, men must be desperate to make money. Although they earn more, their body is overdrawn much more as well. In fact, what men really need is the health, youth and vitality of the whole body. The following substances are the "tonics" which are most needed by men.

First, Vitamin E--to delay the aging
Vitamin E is one of the most effective antioxidants up to now. It has the function of reducing the muscle damage after the exercise. When men have reached 30 to 40 years, fewer and fewer antioxidants are generated in their body. So for men under great living pressure, vitamin E is an effective way to prevent aging. They can eat some nuts and oils to increase the vitamin E intake.

Second, fatty acid--to protect the heart
ω-3s fatty acid can prevent the blood platelet from aggregating and sticking together, so as to increase the mobility of the blood. It can lower the level of blood pressure and triglyceride and maintain the regular beat of the heart. Studies have shown that ω-3s fatty acids can indeed reduce the mortality of heart disease and can effectively treat the immunological diseases, regulate the lipid content in brain cells, and slow down the aging of brain cells. Foods such as sardines, tuna, and herring are considered to be good sources of ω-3s fatty acids.

Third, folic acid--to make men away from early senile dementia
The incidence of early senile dementia in men is very high. The rising of cysteine content can increase the incidence of early senile dementia, which will cause mental deterioration, memory loss and other early symptoms. Study has found that folic acid can effectively reduce the level of cysteine, so as to increase the blood volume entering into the brain. As a result, folic acid can help prevent the formation of arterial thrombosis. Food sources of folic acid include citrus, beans, cereals and so on.

Fourth, --to strengthen the bones of the men
For Chinese men, the daily calcium intake from food is far from meeting their physical needs. What's more, the calcium in the body of the middle-aged men is lost every day. The men who take more calcium tend to have much stronger bones. Experts recommend men to take in 1g of calcium every day. is more suitable for absorption, and drinking more milk can also solve the problem.

In addition, there are other "tonics" which are beneficial to men. For example, chitin is a good "lubricating oil" for men's joint; selenium can help men resist cancer. As a result, men should take in more of the above nutrients in their daily life.
