You have certainly heard that some kinds of fruits and vegetables, oysters, nuts, etc, are very beneficial to men's health. However, there are also some kinds of foods that are not suitable for men, and may even bring damages on their body.

1. Red meat
Red meat, including beef, bacon, sausage, pork luncheon meat, etc, is not only rich in saturated fat, but also contains a lot of cholesterol. The high content of saturated fat and cholesterol may seriously affect men's sexual function. It will narrow down the blood vessels, including the blood vessels to delivery the blood to the sexual parts. Besides, these blood vessels are all very small, so they are easily to be blocked.

2. High-fat milk
Milk and dairy products are the best sources of protein, but there are some differences among them. If it is full-fat product, it is not beneficial to human health. In fact, the harm of high-fat milk and dairy products is as much as that of red meat, because they will also affect men's sexual function.

3. Fried foods
Fried foods, such as French fries, biscuits, cookies, all contain a large number of trans fats. The destruction of trans fats is much worse than that of saturated fat. The U.S. Food and Drug Administration (FDA) has begun to stipulate that, all foods containing trans fats should be stated on the label. As a result, men should eat less of this kind of food.

4. Refined flour
White bread and candy taste very delicious. However, from a nutritional point of view, it is not the fact. When the whole meat is processed into refined bread, three-quarters of zinc will be lost, while zinc is a kind of essential mineral for the cultivation of sexual desire and reproductive health. The highest content of zinc in human body is stored in the prostate. As a result, a diet rich in zinc can help prevent prostate hyperplasia.

5. Soybean
Soybean is not only rich in protein and lecithin, but also can bring down the level of cholesterol in the body, so it is very beneficial to human health. However, a recent research points that, soybean contains certain substance which has the characteristic of estrogen. As a result, excessive intake of soybean may increase the estrogen level in the body, thereby affecting men's sex characteristics. But as long as they do not eat too much soybean every day, it will not bring damage on their body.
