Omega-3 Fatty Acids, Pregnancy, Lactation & Infant Immune Development

By Michael McBurney

On Tuesday, April 5, Dr Philip C Calder was awarded the 10th Danone International Prize for Nutrition in recognition of his nutrition research contributions at the annual meeting of the American Society for Nutrition (ASN).  

In a video interview, Professor Calder discusses his surprise and the personal impact of this award. He highlights the importance of nutrition, especially vitamins and omega-3 fatty acids, in the support of the immune system. In his Tuesday presentation “Feeding the Immune System”, Calder reported on research that children born to mother who eat salmon when pregnant may be less likely to have doctor diagnosed asthma (compared to children who do not eat salmon).

Although the impact of maternal diet on asthma is still being explored, supplementing with omega-3 fatty acids to increase maternal n-3 concentrations during pregnancy and lactation may help support the immune development of infants. There is evidence that increasing omega-3 intake of infants helps reduce the risk of skin and respiratory allergies.  

Almost 20 years ago, Dr R Gibson and colleagues demonstrated breast milk DHA concentrations, and infant plasma and red blood cell DHA concentrations, rise in a dose dependent manner with dietary omega-3 intake.

Based on national surveys (NHANES 2009-2012), we found ~20% of Americans report not eating ANY fish in the previous month. Only 20% recall eating recommended numbers of high omega-3 fish servings per month (4 servings) and of these, only 18% are consuming 250 mg EPA+DHA per day.

When women are not consuming the recommended number of fatty fish servings, it is important to use fish or algal oil EPA+DHA supplements during pregnancy and lactation.
