Eating fish often can lower cholesterol. Most of the fats contained in fish are unsaturated fatty acids, which are easily digested and absorbed by the human body.

Precautions for eating fish:

1, the fish is too red and white to eat. Because of the different kinds of fish, there are red-fleshed fish such as tuna and white-fleshed fish such as hairtail, but if the color of fish is too bright red or bright white, it is probably the "credit" of dyes.

2, the head is "eight points big." The size of a fish determines its taste and safety. Too small, the fish has not grown up and matured, the meat is not tender enough, and fishbones will come out. Too big means that the fish is old and the meat is rough, and there may be a lot of harmful substances accumulated in the body. Therefore, it is more appropriate to buy fish with the size of "eight points".
