Yellowtail, also known as five yellowtails, is also known as octopus, pingang, oily fish, green amberjack or green amberjack. It belongs to the genus Carvelidae, amberjack subfamily, and amberjack. It is a warm-water deep-sea fish. Yellowtail grows fast and has delicious meat, rich in protein, fat, vitamin A, B1 and B2. In Japan, it has a history of breeding for decades, and it has become the first important breeding target for the production of sea cage fish in Japan. Yellowtail is rich in DHA, which is docosahexaenoic acid. DHA is a highly unsaturated fatty acid essential for human brain nutrition. In addition to preventing cholesterol from depositing on blood vessel walls, preventing or reducing the occurrence of atherosclerosis and coronary heart disease, more importantly, DHA has an extremely important effect on brain cells. It accounts for 10% of human brain fat and is extremely beneficial to the growth and development of brain nerve conduction and synapses. experiment

       It shows that if DHA intake is sufficient, the DHA value in the human brain can be increased, which can activate brain nerve cells, improve brain function, and improve judgment ability. There is no doubt that DHA has a very significant brain-building effect, and it is an essential nutrient for young people to enhance their intelligence, strengthen their memory, and improve their learning ability. Yellowtail is known as the "brain-buying supernatural product". Scientists have shown that DHA is only found in fish and a few shellfish. Other foods such as soybeans, butter, vegetable oil, lard, vegetables and fruits almost do not contain DHA. Therefore, from the perspective of nutrition and brain health, if people want to get enough DHA, the most convenient and effective ideal way is to eat more yellowtail.
