Choline Intake During Pregnancy Protects Infants from Mental Illness

Consuming choline during pregnancy protects infants from stress-related illness, including mental disturbances and hypertension, states study. Choline is found in eggs and meat.

Nutrition scientists and obstetricians at Universities of Cornell and Rochester Medical Center found that higher-than-normal amounts of choline in the diet during pregnancy changed epigenetic markers in the foetus.

Pregnant women should pay special attention to their diet. The diet before and during pregnancy should be rich in calories, proteins, vitamins and minerals.

Epigenetic markers are modifications on our DNA that tell our genes to switch on or off, to go gangbusters or keep a low profile.

While these markers don't change our genes, they make a permanent imprint by dictating their fate: If a gene is not expressed - turned on - it's as if it didn't exist, the FASEEB journal reported.

The finding became particularly exciting when researchers discovered that the affected markers were those that regulated the hypothalamic-pituitary-adrenal or HPA axis, which controls virtually all hormone activity in the body, including the production of the hormone cortisol that reflects our response to stress and regulates our metabolism, among other things.

More choline in the mother's diet led to a more stable HPA axis and consequently less cortisol in the foetus. As with many aspects of our health, stability is a very good thing, according to a Rochester statement.

Past research has shown that early exposure to high levels of cortisol, often a result of a mother's anxiety or depression, can increase a baby's lifelong risk of stress-related and metabolic disorders.

"The study is important because it shows that a relatively simple nutrient can have significant effects in prenatal life, and that these effects likely continue to have a long-lasting influence on adult life," said Eva K. Pressman, study author and director of the high-risk pregnancy program at Rochester Medical Centre.

"While our results won't change practice at this point, the idea that maternal choline intake could essentially change foetal genetic expression into adulthood is quite novel," said Pressman.

Pregnant Women Who Eat A Diet High in Choline Can Save the Baby from Stress-related Diseases Later
Pregnant women with increased choline intake in the third trimester of pregnancy can save the baby from metabolic and stress related diseases like diabetes and high blood pressure in later life.

Pressman, who advises pregnant women every day, says choline isn't something people think a lot about because it is already present in many things we eat and there is usually no concern of choline deficiency.
