Studies have found that vitamin D supplementation. Chief physician of the Department of Gastroenterology, Wu Hui. It can not only promote the absorption of calcium, but also reduce the risk of Alzheimer's disease. Many people know that vitamin D and calcium are golden partners. Lack of vitamin D, especially vitamin D3 involved in the absorption rate of calcium is only 10% to 15%, the remaining calcium will not only be excreted with the stool to cause waste, if there is discomfort, hospital visits, but also may cause constipation. And vitamin D food is very much in need of ultraviolet rays through the skin to convert.
But now many people in society do not have time to bask in the sun, or because of excessive sun protection, it is difficult to let the skin directly contact the sun. Therefore, vitamin D deficiency is very common in modern society. Recently, mainland experts have found that daily vitamin D supplementation can effectively delay the occurrence of cognitive decline and neurodegeneration in the elderly. For patients with pre-existing cognitive impairment, vitamin D supplementation can also have brain health benefits. (Daily or occasional VD was associated with a 60.5% and 42.8% reduction in the risk of developing menstrual cognitive impairment into Alzheimer's disease.) Vitamin D itself is a costitral alcohol hormone, in addition to promoting calcium absorption, it plays an important role in cell enhancement and differentiation, calcium signal transmission in the brain, neuronutrition and protection.
In addition, it is able to change nerve conduction and synaptic plasticity. Researchers believe that its prevention and improvement of the causes of dementia are related to the reduction of neurotoxic proteins.
In fact, in my opinion, vitamin D supplementation has dementia function. Another reason is the improvement of osteoporosis. It alleviates some elderly people, because of the lumbar pain caused by osteoporosis, increases the range and frequency of their outing, increases the opportunity and time for him to contact with the outside world, and greatly reduces their thought pressure and released emotions. This point is of great significance for the prevention of Alzheimer's disease.
How to supplement vitamin D to be scientific? For healthy adults, or middle-aged and elderly people without osteoporosis, vitamin D 600 units are needed per day. Elderly people over 65 years old or people who have been diagnosed with osteoporosis need to supplement 1,000 units per day, and need to supplement more than 1,000 fibers per day. Food contains very little vitamin D. If not, those who work outdoors for a long time, most of the daily intake is insufficient, so for the elderly who are inconvenient to move and rarely go out, vitamin D should be properly supplemented.
