Vitamin C can promote intestinal peristalsis, and a proper amount of vitamin C can help digestion and protect the intestine. Eating too much vitamin C is not only not good for the intestine, but also stimulates the peristalsis and secretion of the intestine, leading to an increase in gastric acid secretion, and patients often have diarrhea and gastric reflux.
Excessive vitamin C content will change the secretion of some hormones, such as estrogen, insulin and thyroxine. In addition, when the vitamin C content in the body is too high, our body will "perceive" that the vitamin C content is too high, so the body needs to make a series of reactions to reduce the vitamin C content. In the long run, the body's ability to absorb vitamins will be weakened, and the utilization rate of vitamins will also be reduced. The most common thing is that vitamin B 12 will be destroyed, which is caused by the high content of vitamin C.
Vitamin C can promote the absorption of aluminum, and too high aluminum content will cause damage to bones. In addition, aluminum is called "dementia element" because too high aluminum content will cause damage to the brain. The aluminum content in some patients with Alzheimer's disease is higher than that in the general population. In addition, the high content of vitamin C is also one of the reasons for kidney calculi.
Intravenous injection of large amounts of vitamin C is very dangerous. This will easily lead to hemolysis and coagulation, and in severe cases, it will pose a threat to life. Some patients are allergic to vitamin C, which can cause immune response as an antigen. In addition, intravenous injection of a large amount of vitamin C can also lead to local necrosis of tissues.
There have been cases in which athletes died of excessive intake of vitamin C. This is because these athletes contain more iron in their bodies, and too much vitamin C will promote the transformation of iron atoms and become atomic groups that attack the myocardium. Obviously, taking too much vitamin C will do great harm to the heart and muscles.
In addition, vitamin C is an acidic substance. If the vitamin content in the body is too high, it will interfere with some medical indicators, such as measuring blood sugar and measuring the contents of certain amino acids and enzymes.
It can be seen that vitamin C has many benefits in everyone's eyes. If it is taken in excess, it will cause harm to the body. So how much is excessive? Generally speaking, the daily dosage of vitamin C is within 1g, which is normal; If it exceeds 1g, it means it exceeds the standard. Therefore, although vitamin C is good, it should not be overdone.
