DHA is the abbreviation of docosahexaenioc acid, commonly known as brain gold. It is a long-chain unsaturated fatty acid, an important component of cell growth of the nervous system and the brain and retina, with more than one-fifth of its content in the cerebral cortex and up to half in the retina. Adequate DHA is important for the intellectual and visual development of infants and children. In addition to the body can use linolenic acid and alpha linolenic acid to synthesize DHA, the raw material for synthesis is also present in infant formula. In fact, breast milk contains the above 2 substances, usually 10-20% in the form of phospholipids, which are more easily absorbed. Therefore, breastfeeding is the best if you have the conditions. Of course, if you cannot breastfeed due to health or work reasons, then you should choose infant formula as the best alternative. In 1996, foreign countries have introduced infant formula with DHA. The British Nutrition Foundation and the International Society for the Study of Fatty Acids and Lipids have also recommended that DHA should be added to infant formula. For children and adults, DHA can be obtained entirely from foods such as egg yolk, deep-sea fish and seaweed. As long as the diet is well balanced, then there is no need to worry. It is important to note that according to China’s regulations, DHA is not a necessary ingredient in infant formula, but an optional ingredient, and its added content is clearly defined. This means that your baby’s formula may not contain DHA or may have a limited amount of DHA added to it. However, infants have a lower function of synthesizing DHA, so they need additional supplementation. Since DHA is so good, is it better to give your baby as much as possible? It is not the case, if the supplementation is too much, it will not only increase the digestive burden of infants, but also affect their immune function, cause blood clotting difficulties and other problems. The right amount of DHA supplementation is desirable, but we should pay attention to the principle that: what is lacking to supplement what, never blindly.
