There are some things you don’t have to know, but there are some things you must know. The impact of diet on sex is far greater than people imagine. Recently, a report published in the American "Network MD" pointed out that some common foods can affect people's sexual desire. If you want to have wonderful passion, you must properly control your intake of the following foods.

1. Tofu. Dr. George from the Harvard School of Public Health tracked 99 men from 2000 to 2006 and found that men who ate soy products every day had only 41 million sperm per milliliter of semen, which was significantly lower than those who ate less soy products. male. You can avoid this by eating less than 3 times a week and only 100 grams each time.

2. Fried food. Foods such as French fries, potato chips, and fried pastries are not only difficult to digest, but also contain carcinogens that affect your health. Eating too much of these foods can easily lead to obesity, which in turn affects male sexual function and erection; and can cause endocrine disorders and other problems in women.

3. Fatty meat and sausage. Eating a lot of meat may seem very "manly", but in fact it's quite the opposite. Eating a lot of red meat will reduce the secretion of male hormones and affect the smoothness of blood vessels, making it difficult for the penis to fully erect.

4. Coffee. A small amount of coffee can be refreshing and promote sexual desire. But drinking too much will affect the parasympathetic nerves, resulting in reduced sexual desire.

5. Animal offal. The latest research has found that the livers and kidneys of pigs, cows, and sheep contain different levels of the heavy metal cadmium. Scientific experiments have proven that cadmium can cause difficulty in implantation of fertilized eggs and affect pregnancy.
