Why is there confusion about the effect of DHA?
Carol Haggans, a dietitian and spokeswoman for the National Institutes of Health's National Complementary Supplements Division (NIH), said: "This confusion is common in nutritional research. . DHA has a good theoretical foundation, and researchers have observed that fish and other seafood rich in DHA have similar benefits. However, when researchers added DHA to supplemental nutritional foods and tested it in randomized clinical trials, similar benefits were not observed.
In addition, the level of DHA in each person's body varies, depending on the amount of fish they eat and the effect of genetic modification on the metabolism of fatty acids. Prof. Says Susan Carlson, a nutrition expert at the University of Kansas Medical Center.
DHA supplementation is necessary when the diet is not sufficiently rich in DHA and after consultation with your dietitian or physician.
