Osteoporosis should be prevented from a young age to achieve the best results. Many people believe that osteoporosis is a phenomenon unique to the elderly and that prevention of osteoporosis is a matter for the elderly and has nothing to do with the young, which is a one-sided view. Modern medical research proves that the phenomenon of osteoporosis begins in the young age of people. In children, the amount of bone in the human skeleton, including bone matrix and inorganic salts, increases steadily; in adolescence, the amount of bone increases rapidly; after the age of 35-40, the amount of bone begins to decline. After menopause, bone mass declines significantly faster in women than in men. Studies have also demonstrated that there is a direct relationship between the peak value of bone mass and osteoporosis in each individual. The higher the peak bone mass, the greater the reserve of bone tissue in the body, and subsequently, even if some is gradually lost each year, the remainder is sufficient to delay the appearance of osteoporosis. However, if the reserve of bone tissue is very small, with the loss of bone from year to year (especially women after menopause bone loss to accelerate), the phenomenon of osteoporosis is bound to come early. Therefore, the prevention of osteoporosis should start from the youth, “prevention is better than cure”, in order to achieve satisfactory results. The key points and measures to be taken for the prevention of osteoporosis in young people are: (1) to develop good living and eating habits to maintain the stability of bone mass. For this reason, young people should arrange their diet reasonably and consume more food containing calcium, phosphorus and other essential substances for bone metabolism to supplement the raw materials needed for bone metabolism during the process of physical growth and development. (2) Actively exercise and appropriately increase physical activity to promote blood circulation of bone tissues for their growth and development. When exercising the body, we should consciously increase the load acting on the bones, that is to say, we should stress the bones through sports and exercises to increase the stimulation of the bones, which is conducive to the development of bone trabeculae and the increase of bone volume. A group of foreign research data shows that if women before and after menopause, if they insist on doing jumping up and down every day, the bone density can significantly increase after 1 year, and the degree of osteoporosis can be significantly alleviated. Researchers believe that the human body accelerates the blood circulation of bone tissue throughout the body when doing jumping exercises. At the same time, the impact of the body weight on the bones when jumping also promotes the process of bone formation, so it is extremely beneficial to the prevention of osteoporosis. (3) Quit smoking, alcohol and other bad habits. Smoking and drinking will affect the function of the internal organs, so that the absorption of calcium and phosphorus by the digestive system is reduced, while the excretion from the urine and stool increases, so that the substances required for bone metabolism in the human body are in short supply. (4) Do not eat too much protein and caffeine. Because excess protein in the body metabolism process will produce many acidic substances and excretion from the urine. And these acidic substances in the process of excretion can make the urinary calcium excretion increased, thus increasing the loss of calcium in the body, is not conducive to the prevention of osteoporosis. Some people call this phenomenon the biological “acid rain”. Excessive caffeine intake also promotes the excretion of calcium from urine and stool, which is not conducive to the increase in bone mass. (5) Pay attention to keep the weight within the normal range. Some young people diet excessively in order to lose weight, so that the body will lose valuable bone mass while reducing fat tissue. Because fat is related to the metabolism of estrogen, when the fat level is high, the level of estrogen in the body is relatively high, and estrogen has a direct effect on bone production; when fat is reduced, the level of estrogen in the body is bound to fall, which is not conducive to the prevention of osteoporosis.
