Vitamins are poisonous. It looks like a rumor, but it's true! After 10 years of clinical research, the Cancer Center of the University of Colorado found that people who eat a lot of fruits and vegetables (fruits contain natural vitamins) not only have no anticancer effect, but will increase the risk of cancer. For example, people who take too much carotene have a 20% increased risk of lung cancer and heart disease! ?

Many people may feel that they are always short of vitamins, so taking vitamins every day will make them feel at ease. Sometimes if you don't eat vegetables and fruits for a few days, you convince yourself that there are vitamin tablets to replace anyway. However, the scientific papers published in Annals of Internal Medicine, an authoritative medical journal, show that after analyzing a large-scale comprehensive study involving 500,000 people, scientists have suggested that vitamin supplements are almost invariably a waste of money and harmful to health. Sure! Note that what is said here is that normal and healthy adults regard taking vitamins as a habit, which is not good for their health. But for patients with special diseases, pregnant women, the elderly and so on. The folic acid prescribed by the doctor should still be eaten in quantity.

In real life, we are familiar with many nutrients. Insufficient intake will lead to diseases, while long-term excessive intake will bring other diseases to our bodies. For example, iron, which we are familiar with, can cause anemia, but long-term excessive intake leads to high ferritin level in human body, and the risk of type 2 diabetes can be increased by 2.3 times. For another example, we always think it is safe. As long as we have a cold and fever, the doctor will ask us to supplement vitamin C. If we take it excessively for a long time, the risk of urinary calculi may increase.

To sum up, dietary supplements have always been a double-edged sword. Vitamins are just a part of the dietary supplements we often meet every day. Dietary supplements, as the name implies, are the parts that are not enough to supplement food, or the parts that the body is particularly prone to lack. Therefore, it is necessary to supplement the deficiency, but if the original function of the body is not missing, there is no need to supplement it; If you overdo it, something may go wrong. It is true that vitamins are toxic, but don't add them blindly. It is inappropriate to deny all the functions of vitamins. Natural foods and vegetables already contain vitamins. If you can easily get vitamins from your diet, you should give priority to getting vitamins from your daily diet, and there is no need to supplement them in large quantities.
