Modern people are busy and have an uneven diet. They often use vitamins to supplement their nutritional deficiencies. The most commonly used vitamin is "vitamin C", whether it is a cold or as an antioxidant protection for the skin. Some people will swallow one from time to time, but the doctor reminds, don’t think it’s okay to eat too much vitamin C, it will be excreted anyway, be careful that high doses can cause cataracts, and may even cause cancer!
Jiang Kunjun, deputy director of research at Minsheng Hospital, pointed out that vitamin C has been studied in recent years, and it has the functions of beauty and anti-aging. Because it can increase collagen synthesis, it is also a strong antioxidant. Many women like to supplement high units Vitamin C. Many people also believe that vitamin C is water-soluble, and it will be fine if you eat too much. Even if it is ineffective, it will be excreted in the urine. However, in fact, medical research has found that taking too high a dose of vitamin C may threaten your health. .
Jiang Kunjun said that vitamin C is originally a strong antioxidant, but taking too much will cause oxidation. At this time, the oxidative stress of the crystal in the eyes will increase. Once the oxidative stress increases, it may cause cataracts. In addition, vitamin C still needs to be metabolized by the human body. When it is metabolized, it will become oxalic acid. If you take too much, it will cause calcium oxalate stones in the urine.
Jiang Kunjun further pointed out that there are also studies in medical journals abroad that excessive intake of vitamin C may cause cancer, because the human immune system sometimes needs to create some oxidative stress when removing some cancer cells in the body.Too many antioxidants will cause the elimination of oxidative stress, which is not conducive to immune cells to eliminate cancer cells.
Jiang Kunjun emphasized that vitamins are an important role in many biochemical reactions in the body. If they are not ingested enough, the body will still have problems. Taking vitamin C as an example, the recommended daily intake is 100-200 mg. If the average person eats 3 servings of vegetables and 2 servings of fruit every day, they will probably have enough vitamin C intake every day. In fact, there is no need for additional supplementation. If foodies can't eat 3 vegetables and 2 fruits, they can add some extra vitamins, but Jiang Kunjun reminded not to add too much to a single vitamin, "balanced diet" is the best solution.
