1, when taking vitamin C, you can't eat it with shrimp, because eating it with shrimp will be toxic.
2, can not be eaten with pig liver, if vitamin C is taken with pig liver, copper ions and iron ions in pig liver will quickly oxidize vitamin C into dehydroascorbic acid, losing its original function.
3. Foods rich in vitamin B2, such as cheese, seafood, eggs, milk and animal offal, should not be eaten in large quantities. This is because vitamin C is reducible, while vitamin B2 is redox, and its oxidation is greater than reducibility. When they are used together, not only will vitamin C lose its efficacy due to redox reaction, but vitamin B2 in these foods can't play its due role in the body, which can be described as "both sides lose".
4, eating vitamin C is not suitable for eating a lot of vegetables such as cucumbers, carrots, pumpkins and so on. Because these vegetables contain vitamin C decomposing enzymes, it will destroy vitamin C and make it ineffective.
In addition, don't smoke with vitamin C.
Medical research shows that the content of vitamin C in serum, white blood cells and urine of smokers is lower than normal, and vitamin C with antioxidant effect can enhance the body's resistance and reduce the harm of smoking. Therefore, smokers are usually advised to supplement vitamin C in moderation.
Smoking will change the expression of vitamin C in saliva and become a substance harmful to health. Therefore, the research team suggests that if it is difficult to quit smoking for a while, you should at least give up the habit of taking vitamin C while smoking.
6. Milk Vc is easily oxidized, acidic and reducible. Milk is rich in vitamin B2, which has a certain oxidation effect. When taken at the same time, Vc is easily oxidized by vitamin B2, while vitamin B2 decreases and loses its function.
