There is a close interrelationship between food and human sexual function. Traditional medicine and modern medicine both believe that medicine is better than food, choose meals with special effects can achieve the purpose of strengthening essence, aphrodisiac, kidney and body, etc. Meals with the effect of kidney and aphrodisiac can have a powerful impact on libido, sexual response and sexual behavior. From the perspective of maintaining and regulating sexual function, the following principles should be mastered in the daily diet: 1. Sufficient intake of high-quality protein: protein contains a variety of amino acids required for human activity, which are involved in the composition of human tissue cells, including sex organs and reproductive cells. For example, arginine is an important component of sperm production and has the effect of improving sexual function and eliminating fatigue. Soy foods, especially frozen tofu, are rich in arginine. The sources of high-quality protein are mainly poultry, eggs, fish, meat and other animal proteins and bean proteins. 2, should pay attention to the enzyme supplement: enzyme is a special protein with catalytic effect in the body, can promote the body’s metabolism. If the body lacks enzymes, can appear a variety of functional decline (including hypogonadism), and even the loss of fertility. Enzymes exist in all kinds of food, in cooking food should pay attention to the temperature should not be too high, the time should not be too long, not with frying, baking, frying and other cooking methods, so as not to make the enzyme is destroyed. 3, supply the right amount of fat: In recent years, as people’s health awareness, most adult men worry about the intake of fat and cholesterol will lead to obesity, heart disease, so there are a number of people because of the fear of fat psychology and eat vegetarian food. From the point of view of maintaining sexual function, it is still appropriate to consume a certain amount of fat. Because the synthesis of sex hormones in the human body is not conducive to the maintenance of sexual function. In addition, fat contains some fatty acids necessary for sperm production. If these essential fatty acids are lacking, it will not only affect sperm production, but also lead to a decrease in libido. Moderate consumption of fat also helps the absorption of vitamin A, vitamin E and other fat-soluble vitamins. Meat, fish, poultry eggs contain more cholesterol, moderate intake is conducive to the synthesis of sex hormones, especially animal offal itself contains sex hormones, it is appropriate to choose to eat in moderation. 4, pay attention to the supplementation of vitamins and trace elements related to sexual function: modern medical research shows that the lack of zinc in the human body can cause a decrease in the number of sperm, an increase in the number of deformed sperm, as well as sexual and reproductive function, and even infertility.
