What is the nutritional value of octopus?

1. Octopus is a high-protein food. The protein content is not inferior to that of ordinary beef, pork and fish. It is 6 times the protein content of milk and contains all the essential amino acids for the human body. It is a real high-quality protein.

2. Octopus has a very low fat content, with only 0.4 grams of fat in 100 grams, while the same weight of lean pork has 6.2 grams of fat, and grass carp, which is also aquatic product, has 3.2 grams of fat per 100 grams of fish. Therefore, if we want to take in protein but don't want to exceed the fat intake limit, octopus is a good choice.

3. Octopus is rich in taurine. The taurine content in octopus is much higher than that in ordinary meat. It can resist fatigue, lower blood pressure and soften blood vessels. It is suitable for diseases such as hypertension, low corridor pressure, arteriosclerosis, cerebral thrombosis, carbuncle and swelling.
