Many people know that soybean has phytohormones, which are good for women, but they don't know that soybean is also an excellent food for men. For example, Japanese men who often eat soy products are less likely to develop prostate cancer than western men. In addition, soybean is also effective in improving male bone loss. When men are over 60 years old, they will begin to lose bone, which is as serious as menopausal women. And eating more soybeans can supplement lecithin, which has been proved to be related to short-term memory and learning ability. After the age of 40, most men have enlarged prostate. An experiment in the United States found that letting patients with prostatic hypertrophy take melon seed extract can really reduce urinary frequency and improve other symptoms. Moreover, melon seeds are also the best source of vitamin E, which can resist aging.
