The reason for American experts is that spinach can promote muscle growth and improve sexual performance. The article points out that spinach can provide a certain amount of energy for the synthesis of muscles, and it can also accelerate the blood circulation to the reproductive organs and improve sexual performance. Nutrition experts in China have also expressed their recognition of the nutritional value of spinach. Speaking of folic acid, many people first responded to the "patent" of pregnant women, but Xu Hui, chief physician of the Nutrition Department of Shanghai Sixth People's Hospital, told reporters that in fact, folic acid is also an element that needs to be added to enhance the fitness effect. Spinach is rich in folic acid, and its folic acid content is as high as 347 micrograms per 100 grams of spinach, ranking first among vegetables. Folic acid not only helps to show the strength of a man's biceps contraction, but also provides the energy needed for muscle growth, but also makes the muscle more sensitive to insulin and helps to increase muscle and reduce fat. The trace element magnesium contained in spinach also converts the carbohydrates in the muscle into usable energy, thereby increasing muscle strength. Of course, the more attractive advantage of spinach for men is that their rich in folic acid and iron can promote the synthesis of red blood cells, increase the amount of oxygen carried by blood, and thus accelerate blood circulation. From this perspective, spinach can also improve the quality of sexual life. The advantage of spinach, which can speed up blood circulation, is also a good choice for daily diet to reduce the risk of heart disease, stroke and osteoporosis. For the elderly, a prominent advantage of spinach is its rich lutein can delay the deterioration of the age-related macular. Xu Hui pointed out that eating more spinach can prevent aging of the human body from falling off, because spinach contains antioxidants, can prevent the elderly's eyes, "macular degeneration", delay the aging of the elderly macular degeneration and aging caused by blindness or vision decline. In addition to spinach, the other seven foods recommended by the American nutrition experts for men to eat each day are: yogurt (or yogurt), tomatoes, carrots, blueberries (or strawberries, purple grapes), black beans (or peas), walnuts, oats .
