Nutritional Value of Tilapia

1. Tilapia meat contains a lot of protein and amino acids, including a variety of essential amino acids needed by the human body, such as glutamic acid and glycine, and is a high-quality high-protein product. The fish protein content is not only higher than that of meat protein, but also easier for the human body to digest and absorb, making full use of the nutrients ingested.

2. Tilapia contains a lot of taurine, with about 210-220 mg of taurine per 100 g of fish. Taurine is very beneficial to the human body.

3. Tilapia muscle contains a large amount of unsaturated fatty acids and a certain amount of DHA and EPA. DHA and EPA are very beneficial to the development of human brain and vision. They help prevent heart disease, high blood pressure and high fat, and many other diseases, improve physical fitness, and maintain physical health.

Why is eating tilapia harmful?

Because tilapia is a fish with a very strong adaptability to the environment, if you eat wild tilapia that grows in dirty water, it will be harmful to your health. Tilapia does not require a high level of environmental cleanliness and can survive normally even in urban sewage outlets.

Tilapia is a freshwater fish that is very easy to raise. It has a short spawning cycle and can incubate young fish in its mouth, so it has strong reproductive capacity. Not only is the yield high, but the breeding cost is also low, so the price is naturally cheap.

Tilapia that is farmed properly is edible and has high nutritional value, similar to other freshwater fish, and is cheap.

Please be careful not to eat wild tilapia that live in sewage. They may have parasites and other things in their bodies, and they will have a strong earthy smell. It is not recommended to eat this kind of tilapia.

Tilapia eating taboos

1. Do not eat fish that is not cleaned or cooked. Some freshwater fish are susceptible to infection by Clonorchis sinensis cysts and larvae, which can parasitize in the liver and cause disease, especially in the fish head.

2. The black film on the belly of fish cannot be eaten. There is a thin layer of black film on the inner wall of the fish's abdominal cavity. This is the protective layer of the fish's abdomen. It can protect the inner wall of the abdominal cavity from friction with other organs, and also plays a role in isolation, preventing other organs from secreting harmful substances that penetrate into the muscles. It can also be said that this layer of black film is the gathering place of various harmful substances. If people eat it, they will experience nausea, vomiting or diarrhea. When cleaning fish, be sure to remove the black film in the abdomen.
