Pregnancy is in women's bodies, as long as women focus on nutrition is sufficient. For men, the impact is not significant.
Focus only on nutrition during pregnancy, ignoring nutritional preparation before pregnancy.
"Eating nutritious food" is understood as "nourishing".
Some parts are correct. That is, in the stage of preparing to conceive a baby, the nutrition of the man is also very important. "Because the husband has sufficient nutrition, the sperm becomes more energetic, making it easier for the wife to conceive.".
High quality protein: sufficient but not excessive
Protein is an important component of cells and an important raw material for sperm production. Reasonable supplementation of high-quality protein rich foods is beneficial for coordinating male endocrine functions and improving the quantity and quality of male sperm.
Fish and shrimp, oysters, lean meat, eggs, soybeans and their products. In particular, seafood not only has a low level of pollution, but also contains nutrients such as DHA and EHA that promote brain development and physical fitness. Targeting at dads is very beneficial.
However, long-term excessive protein intake can easily disrupt the balance of nutrients in the body, resulting in insufficient intake of vitamins and other substances, which is detrimental to pregnancy. Generally, high-quality protein (animal protein and soybean protein) should account for 30% to 50% of the total dietary protein.
Zinc and Selenium: Reasonable Supplement
Minerals and trace elements in the human body also have a very important impact on male fertility. The most common elements are zinc, selenium, and other elements, which are involved in the synthesis and delivery of testosterone in men, helping to improve sperm activity and reproductive physiological activities such as fertilization.
Due to zinc deficiency, the number of sperm will decrease, the number of abnormal sperm will increase, sperm motility, sexual and reproductive functions will decrease, and even cause infertility; Due to selenium deficiency, the energy source required for sperm activity decreases, and sperm motility decreases.
Foods with high zinc content include shellfish, seafood, animal offal, cereal germ, sesame seeds, shrimp, and other foods; Foods with high selenium content mainly include seafood such as kelp, cuttlefish, shrimp, seaweed, and so on.
Reasonable supplementation of zinc and selenium can be based on the daily reference intake of dietary nutrients. Zinc: The recommended daily intake for adult men is 15.5 mg/day. Selenium: The recommended daily amount for people over the age of 18 is 50 micrograms per day.
