This study conducted an 11-year follow-up survey of 21000 men. The results showed that men who consumed more than 600 mg of calcium per day through dairy products had a 32% higher risk of prostate cancer than those who consumed less than 150 mg of calcium per day.
This finding shows a link between high intake of dairy products and prostate cancer. Daily intake of calcium from dairy products will inhibit the level of vitamin D in the blood.
The report points out that vitamin D is not only an important nutrient, but also a hormone that can prevent the proliferation of prostate cancer tumor cells, thus playing a role in preventing prostate cancer. Lin Chuanxian, a urologist at Elizabeth Hospital, believes that the latest investigation needs further research to determine the role of vitamin D in the prevention of prostate cancer and how calcium affects the level of vitamin D. He said that clinical observation also found that prostate cancer occurred more often in the population of developed countries, indicating that it has a certain relationship with eating habits. Other factors include aging and heredity.
Therefore, older men should pay more attention to healthy diet, such as eating less meat, exercising regularly and eating more low-fat food, soy food, vegetables and fruits.
The prostate is a male accessory reproductive organ between the bladder and the urethra. Its function is to secrete a milky liquid to nourish the sperm for survival. In addition to dairy products, the rich source of calcium also includes dark green vegetables, bean products, sardine, and so on.
