Everyone is familiar with vitamins, they are one of the seven essential nutrients to maintain the normal metabolism and health of the human body.
Different vitamins have different effects, and research into them has been ongoing, with recent studies finding that vitamin D supplementation may help fight cancer!
1. The latest research: supplementing this vitamin may help fight cancer
When it comes to vitamin D, everyone's first reaction must be calcium supplementation and bone strengthening, but in fact, its role is much more than that.
Last week, a study published in the top journal Science by the National Cancer Institute and other institutions pointed out that vitamin D plays an important role in immune regulation and cancer.
The study was conducted in mice, and found that vitamin D can promote the growth of intestinal bacteria Bacteroides fragilis, thereby improving the body's immunity to cancer, enhancing the effect of immune checkpoint inhibition, and inhibiting tumor growth.
Is it true that the more vitamin D you eat, the better?
Of course not, on the one hand, more research is needed to verify whether vitamin D can have the same mechanism in the human body, and on the other hand, this study is mainly to determine that improving vitamin D deficiency for cancer prevention and treatment, and does not apply to the condition of vitamin D deficiency.
Excessive intake of vitamin D can cause an increase in blood calcium, kidney and heart function is impaired, and vitamin D must not be supplemented at will every day.
Before supplementing with vitamin D, you should go to the hospital for professional testing to confirm that you are vitamin D deficient. For ordinary people, doing these two things well every day will generally not lack vitamin D.
1. Exposure to the sun: Between 11~15 o'clock, you can expose your face and upper arms to the sun for 5~30 minutes, 3 times a week, to prevent vitamin D deficiency.
2. Supplement: You can eat more fish, animal liver, fruits and vegetables every day, which can help the body replenish vitamin D.
Second, excessive supplementation of these 3 vitamins may harm your health
At present, there are various vitamin supplements on the market, and the merchants will emphasize the dangers of vitamin deficiency, but few people mention that excessive vitamin intake can also be a health threat. Many people's first reaction after seeing an ad is to eat something just in case, but this idea is very incorrect.
People who eat regularly do not need additional vitamin supplements, and even if they do, it is not recommended to take them for 5 consecutive days >. In addition to vitamin D, these vitamins should not be supplemented in excess.
1. Vitamin A
Intake of a large amount of vitamin A in a short period of time will lead to acute poisoning of the body, manifested as dizziness, drowsiness, vomiting, diarrhea, etc.;
If a small amount of vitamin A is consumed in excess over a long period of time, it can cause chronic toxicity, manifested as joint pain, swelling, abdominal pain, itchy skin, and fatigue.
2. B vitamins
A high intake of B vitamins can cause the body to experience symptoms such as irritability, tiredness, and decreased appetite.
3. Vitamin E
Long-term intake of vitamin E > 1000mg/day will lead to body toxicity, manifested as blood clots, high blood pressure, pulmonary embolism, etc.
3. Middle-aged and elderly people often eat these three things, which is better than eating health products every day
Many elderly people like to eat all kinds of supplements to maintain their health, thinking that expensive is good.
In this regard, Zhao Qihua, chief physician of the Clinical Nutrition Management Department of Subei People's Hospital, said that many expensive health care products are not suitable for everyone. Health products such as ginseng and deer antler velvet will increase the burden on the elderly with weak spleen and stomach and good health.
It is recommended that the elderly can eat more of these foods in their daily life, which is better than health supplements.
1. Milk
Milk is rich in calcium, and it is similar to the structure that the body can absorb, and can also promote the absorption of vitamin D, which can play a good role in strengthening bones. And milk is rich in potassium, magnesium and other elements, which can help control blood pressure.
2. Fruits and vegetables
Each person should ensure the intake of 500g of vegetables and 250g of fruits every day, and the intake of sufficient vegetables and fruits can allow the body to supplement vitamins, minerals, dietary fiber, etc., which is a very important part of a reasonable diet. Insufficient intake of fruits and vegetables will increase the risk of high blood pressure and cardiovascular disease.
3. Meat
Meat is rich in protein and fat, which can provide nutrients for the body, as well as rich in nutrients such as vitamin B12 and minerals, which are very easy for the elderly to lack.
In addition, the elderly are prone to protein deficiency and muscle loss with age, so eating meat can be a good way to supplement protein and prevent the occurrence of sarcopenia.
In addition, the concentration of antioxidants in the body decreases as the elderly age, and the aging of the brain will also accelerate as a result. Eating meat increases antioxidant concentrations, which are good for reducing brain cell damage and preventing memory loss.
For the elderly, nutritional supplementation is very important, if the lack of nutrition, the impact on the body may not be intuitive, but it has been affecting the physical state continuously. If you can, you can eat more meat, milk, vegetables and fruits.
