Vitamins are essential nutrients for the normal operation of our bodies, and vitamin D is particularly important for our health. Adequate vitamin D can promote the absorption and metabolism of trace elements calcium and phosphorus, help muscles to produce protein, and improve the balance ability of the body. However, if vitamin D is lacking, the body will have corresponding problems. Performance of vitamin D deficiency: Adults with bone pain who lack vitamin D are the most common symptoms of bone pain after waking up. This symptom is especially obvious on cloudy days. Being overweight will reduce the content of vitamin D in the blood. Vitamin d is fat-soluble. The more fat in the body, the easier it is to dilute vitamin D in the body. Therefore, obese people should pay special attention to vitamin D supplementation than people with normal weight. Most people who are easily upset have feelings. I am in a bad mood on a cloudy day. ?

Studies have shown that vitamin D supplementation can reduce depression. Ways to supplement vitamin D: It can be supplemented by dietary supplements. Some animal livers, egg yolks, fish, mushrooms, etc. are rich in vitamin D, so you can eat a lot at ordinary times. Many drinks also contain a lot of vitamin D. Something like milk is a good choice. In addition to supplementing diet, sunbathing is also a good choice to supplement vitamin D. Usually, you should get as much sunshine as possible on your arms, legs, abdomen and back for about 15 minutes each time, preferably between 10 and 4 pm every day. For the elderly, calcium deficiency can lead to osteoporosis and fractures, so don't be short of calcium at any stage of life. These calcium-containing foods often bask in the sun at the same time, so children and teenagers need more food when they grow up, and they can drink calcium-containing milk appropriately.

A new study shows that vitamin D deficiency may lead to skeletal muscle dysfunction in adults over 60 years old. Maintaining lifelong skeletal muscle function is an important part of successful aging, which helps to promote independence, mobility, quality of life and reduce falls and weakness. As we all know, resistance training can maintain muscle function, but more and more evidence shows that adequate vitamin D status may also have protective effect. Maria O 'Sullivan, associate professor of nutrition at Trinity College in Ireland, said: "Our findings confirm that vitamin D deficiency will increase the possibility of muscle dysfunction in the elderly, thus protecting physical activity." . "In the process of promoting healthy aging, maintaining muscle function is extremely important, but it is often overlooked.

These findings are based on the data analysis of more than 4000 adults over 60 years old, which are from the longitudinal study of aging in Britain. The research results published in the International Journal of Clinical Intervention on Aging show that the prevalence of myasthenia in the elderly who lack vitamin D is twice as high as that of vitamin D. Similarly, the "muscle performance" of the elderly who lack vitamin D is three times as high as that of the elderly who are full of vitamin D. According to more complicated statistical analysis, vitamin D deficiency will increase muscle strength, indicating the possibility of injury. This study confirms the related benefits of physical exercise. Older people who often participate in moderate-intensity physical activities are less likely to have poor muscle strength and physical fitness.
