On August 31, the Market Supervision Bureau of Zhangdian District, Zibo City, Shandong Province issued consumption tips, introducing how to buy seawater fish and freshwater fish. Regarding seawater fish, the market supervision department gave you two popular concepts: DHA and EPA. The scientific name of DHA is docosahexaenoic acid, and the scientific name of EPA is eicosapentaenoic acid. They are two important components of Omega-3 polyunsaturated fatty acids, which can prevent cardiovascular diseases and promote brain development. These two fatty acids have multiple benefits for adults, such as lowering blood lipids, improving blood circulation, inhibiting platelet aggregation, and preventing atherosclerosis and thrombosis. In addition, DHA is also an indispensable nutrient for infant vision and brain development.
People often mistakenly believe that only sea fish contain DHA and EPA. In fact, freshwater fish is also a good source of these two important fatty acids that benefit the brain and body.
