Many people regard fish oil as a daily essential health care product, and sometimes increase the dosage, thinking that eating more health care products is harmless to the body. That was not the case. Let's look at the truth.

In fact, there are too many unsaturated fatty acids in the body, which can easily lead to peroxidation, consumption of antioxidant substances and cell aging. For children, it doesn't mean that eating more fish oil will make them smarter. In addition, fish oil contains a lot of unsaturated fatty acids, so it is best not to drink tea when eating fish oil, so as to avoid the interaction between theophylline and tannic acid in tea and fish oil, which will affect the health care achievements.

Because the amount of unsaturated fatty acids in ordinary fish is very small, only deep-sea fish in cold regions, such as salmon and sardines, have extremely high unsaturated fatty acids, so it is not easy to buy pure fish oil in the market.

In fact, it is a better choice to take unsaturated fatty acids from seafood and aquatic products. Adults can keep healthy by consuming 30% unsaturated fatty acids every day. It is recommended to eat deep-sea fish 3-4 times a week to meet daily needs. Fish oil supplements also vary from person to person. For people who are used to eating fish, there is no need to take extra fish oil. For the elderly who eat less fish, they can take it appropriately.

It should be noted that fish oil should not be confused with cod liver oil. The raw material of cod liver oil is fish liver, and the main components are vitamins A and D, which are fat-soluble vitamins.

If you take cod liver oil as fish oil and take it in large quantities for a long time, it will cause excessive accumulation of vitamins in the body and cannot be metabolized, leading to poisoning and increased brain pressure.
