Babies can be given enriched eggs to boost levels of the essential fatty acid, docosahexaenoic acid (DHA), without increasing total plasma cholesterol.
Nutritionists and paediatricians from the Women’s and Children’s Hospital in Adelaide, Australia found that children who ate four yolks from the DHA-enriched eggs a week had 30-40 per cent more DHA in samples of erythrocytes, than those fed regular egg yolks or no eggs at all.
The effect was seen in both breast-fed and formula-fed children. DHA, an omega-3 fatty acid, is an essential part of the diet, and is understood to have a key role in brain development.
There is some concern that growing infants consume too little DHA or other omega-3 fatty acids. In the nutritional trial there was no effect of egg treatment on plasma cholesterol, hemoglobin, ferritin or transferrin, but there were improvements in plasma iron and transferrin saturation compared to no egg treatment. The researchers looked at the effect of egg treatment and no dietary intervention on a total of 70 breast-fed infants, and 67 formula-fed infants aged six to 12 months. Each of these two groups was divided into three further groups: no intervention; feeding with enriched eggs; and feeding with regular eggs.
