People of all ages should focus on osteoporosis prevention, and the lifestyles of both infants and young adults are closely linked to the development of osteoporosis. The mineral content of the human skeleton reaches its highest level in the 30s, which is medically known as peak bone mass. The higher the peak bone mass, the greater the “bone mineral bank” reserve in the human body, and the more delayed and less severe the onset of osteoporosis in old age. Active improvement of diet and lifestyle and adherence to calcium and vitamin D supplementation in old age can prevent or reduce osteoporosis. 1.Balanced diet: Increase the intake of calcium and moderate amount of protein in the diet and low salt diet. Calcium intake has an irreplaceable role in the prevention of osteoporosis. Smoking, alcoholism, excessive intake of caffeine and high phosphorus drinks will increase the risk of osteoporosis. 2, moderate exercise: human bone tissue is a living tissue, people in the movement of muscle activity will continue to stimulate the bone tissue, making the bones stronger. Exercise also helps to enhance the body’s responsiveness, improve balance function and reduce the risk of falls. This makes osteoporosis less likely to occur. 3. Increase sunlight exposure: The Chinese diet contains very limited vitamin D. A large amount of vitamin D3 depends on the synthesis of the skin after receiving ultraviolet radiation from the sun. Regular exposure to sunlight will play a key role in the production of vitamin D and calcium absorption. The average normal person receives at least 20 minutes of sunlight per day. Tip: Sunscreen and umbrellas can also increase the chances of osteoporosis in women. The usual lack of outdoor light, and go out and put on thick sunscreen or use a sunshade, will affect the body’s vitamin D synthesis.
