Vitamin D cannot be eaten randomly!Chinese scholar: can increase Alzheimer's disease

Alzheimer's disease, also known as Alzheimer's disease, is a degenerative disease of the nervous system, which occurs mostly in the elderly group. With the aging of the society, the prevalence of Alzheimer's disease has increased year by year, and it is rapidly becoming a worldwide public health problem, but the current drugs have a small improving effect on Alzheimer's disease.

Vitamin D supplement is a must -have in the home of many elderly people. Natural vitamin D exists in fish, such as salmon, sardines, catfish, and so on. As we all know, vitamin D is an essential trace element for the human body, which is beneficial to the health of the elderly's bones and teeth, which can help prevent and treat osteoporosis and reduce risk of fracture. However, although vitamin D is good, don't add too much.

The daily daily dose of vitamin D is 1000-2000IU recommended by experts. This dose can reach sufficient serum vitamin D level without significant side effects. If you have the precursor of Alzheimer's precursor, you should pay attention not to over -supplement vitamin D. Research on the latest group of crowds shows that long -term supplementation of vitamin D increases the risk of dementia.

The research team led by RAI-HUA LAI and Chih-Cheng HSU from Taiwan from Taiwan conducted a retrospective queue research. Using Taiwan's health insurance database, users who chose orthopedic methanol were selected as research objects. Occupation tripopol is an analog of vitamin D, which plays the same physiological role as vitamin D in the body, including promoting calcium absorption, enhancing osteopia, etc., which can be regarded as vitamin D supplementary agent.

The research team found that in 14648 dementia -free elderly patients with vitamin D supplements for more than 146 days each year, the risk of dementia is 1.8 times that the elderly who do not take vitamin D supplements. Among the 980 patients with dementia, patients taking vitamin supplemeters D taking vitamin D3 supplements for more than 146 days each year is 2.17 times that the elderly who do not take vitamin D supplements in the control group are not taking vitamin D supplements.

Regarding the molecular mechanism of vitamin D to aggravate Alzheimer's disease, researchers believe that excessive supplementation of vitamin D will cause β amyloid protein to deposit. This protein appears in the brain of elderly dementia patients, causing the formation of elderly plaques in the brain and the apoptosis of nerve cells. It is considered an important factor that causes dementia.

This human queue studied a warning of Alzheimer's patients with dementia who took vitamin D supplements for a long time. Since vitamin D is recently considered to aggravate Alzheimer's dementia, let's take a look at the recognized methods that can prevent dementia.

1. Actively exercise

Exercise can promote the emergence of neurobin and effectively prevent brain degeneration.

2. Reduce the intake of aluminum elements

Studies have found that too much aluminum intake can easily induce senile dementia. Foods with high aluminum content in daily life are the fritters, because alum is added to the fritters, and the scientific name of the alum is exactly the potassium of aluminum sulfate. Therefore, the amount of fritters should be reduced.

3. Ensure sufficient sleep

For the elderly, it is important to make the brain fully rest. It can reduce the pressure of the central nervous system and help reduce the risk of dementia.
