Pregnant mothers have added an IQ tax to add additional DHA?

Many pregnant mothers consult us, should we add additional DHA during pregnancy?To answer this question, we must first understand what DHA is.

DHA, which is 22 carbonic acid, is a long unodium unsaturated fatty acid with biological activity.There is no clear evidence at present, showing that supplementing omega-3 long-chain polyunsaturated fatty acids during pregnancy can improve the nerve development of future generations.Because one of the critical mixed factor is that intake of sufficient seafood may be a sign of healthy lifestyle or high socioeconomic status. Is the descendants smart because of the good family economic conditions, or because of DHA?This is difficult to reach consensus.

However, because DHA may promote neurological development and reduce premature birth rate, it may also reduce allergic and special diseases of offspring. Therefore, we recommend pregnant mothers to consume 2 to 3 deep -sea -rich deep -sea fish rich in DHA per week.

We recommend pregnant mothers to supplement DHA from food.Fish is a healthy food with low saturated fat content and rich protein. Eat 2 to 3 parts of deep -sea fish rich in DHA and low mercury is the best way to obtain DHA, such as sardines, phoenix fish, catfish, catfish, bifescence fish., Huanghua Fish, Luo Feiyu, Sanye Fish, and Seafood products such as scallops, oysters, clams, squid and other seafood.

In addition, α-linolenic acid also belongs to the omega-3 long chain multi-unsaturated fatty acid, which can be converted into DHA in the body, but the conversion rate is extremely low.α-linolenic acid can be obtained from linseed oil, mustard seed oil, soybean oil, perilla seed oil, walnut oil, nuts and pumpkin seeds.Therefore, intake of marine omega-3 long-chain polyunsaturated fatty acids is the most effective way to improve the level of human DHA.

Speaking of which, some pregnant mothers may ask: "I don’t like to eat fish, can I eat DHA supplements?" In this case, you can strengthen the food with DHA supplements or DHA to meet the photography of at least 200 to 300mg DHA per dayEnter the target.

However, it should be noted that DHA supplements are health products and are not drugs.Since there is no regulatory agency to fully monitor them, the quality of these supplements is different, which means that the content of DHA in the product cannot be ensured that the content of DHA is consistent with the label of health products.Theoretically, the DHA supplement that originated from seaweed preparations almost does not contain mercury.
