Eating eggs during pregnancy may lessen stress for baby

Increasing intake of choline, a nutrient found in high quantities in eggs, during pregnancy may reduce the risk of the baby developing metabolic and chronic stress-related diseases like high blood pressure and diabetes later in life, suggests a new research from Cornell University.

The study suggested that choline might help protect against the effects of a mother’s stress during pregnancy.

Previous research indicates high exposure to the stress hormone cortisol during pregnancy, often due to maternal anxiety or depression, may make offspring vulnerable to stress-induced illness and chronic conditions.

This new finding adds to the growing body of evidence demonstrating the importance of choline in fetal development.

Twenty-four women in the third trimester of pregnancy were randomly assigned to consume either 480 milligrams (mg) choline per day or 930 mg per day for 12 weeks prior to delivery.

Researchers collected maternal and placental blood samples as well as samples of placental tissue. They then compared cortisol levels and genetic differences among all the samples. The researchers observed lower levels of cortisol in the placental cord and changes in cortisol-regulating genes in both the placental and fetal tissue among women in the higher choline intake group.

“The study findings raise the exciting possibility that a higher maternal choline intake may counter some of the adverse effects of prenatal stress on behavioral, neuroendocrine, and metabolic development in the offspring,” said Marie Caudill, PhD, Cornell University, who is an author of the study and a leading choline researcher.

Choline is especially important for pregnant women – it has been shown to play an important role in fetal and infant brain development, affecting the areas of the brain responsible for memory and life-long learning ability.

In addition, research has shown women with diets low in choline have four times greater risk of having babies with neural tube defects, such as spina bifida.

Emerging research also shown choline may have additional benefits in other areas, including breast cancer prevention, anti-inflammatory, brain function etc.

Eggs are an excellent source of choline, containing 125 mg per egg. It is found exclusively in the yolk, not the white.

Neva Cochran, registered dietitian and nutrition communications consultant, explains that the nutritional benefits of eggs are not merely limited to choline.

“Not only are eggs an excellent source of choline, they contain many other nutrients pregnant women need most, such as high-quality protein, iron and folate-all for just about 15 cents apiece,” said Cochran.

Cochran suggests suggested that the best way to get your daily dose of choline is to include choline-rich foods in the diet, such as eggs, lean beef, cauliflower and peanuts.

The study has been published in the latest edition of the Journal of the Federation of American Societies for Experimental Biology.
