Maternal Diet has Far-Reaching Consequences


Pregnancy is perhaps the most important time to make wise dietary choices.  Not only does fetal growth depend on the quality of mom's diet, but the food choices a mom makes have effects that extend into her child's adult years.  The first effects of mom's diet are on the baby's insulin and glucose levels immediately at birth. 

A new study has demonstrated the importance of a healthy maternal diet as a way of avoiding increased insulin and glucose levels in the child, which are indicators of diabetes and metabolic syndrome risk.  The study was headed by the Complutense University of Madrid and published in the European Journal of Clinical Nutrition, which studies diet during this vital stage and sees cell growth in terms of both number and size.

Previous studies have already outlined that when the mother does not consume enough food during pregnancy, the glucose supply to other tissues is reduced in the fetus to ensure that the brain receives the correct amount. In turn, this causes reduced fetal growth. This adaptive mechanism is known as Barker’s thrifty phenotype hypothesis.

“However, the effects of an imbalance between fats, proteins and carbohydrates are not as well-known. In others words, the effect during pregnancy of Western diets that vary greatly from the Mediterranean variety are not well-known,” as explained by Francisco J. Sánchez-Muniz, researcher at the Complutense University of Madrid and one of the authors of the study.

The new study reveals that when pregnant women ingest adequate energy quantities, their children are born at a normal weight of around 7.2 pounds to 7.7 pounds. 

The experts state that when a woman does not eat properly during pregnancy, the child is born with a diabetogenic profile, meaning high levels of serum glucose and insulin and a marker of insulin resistance.  This confirms the influence of the diet on fetal pancreas development as well as glucose and insulin concentration at birth. 

But what hat is “proper” eating?  The researchers concluded that a balanced Mediterranean diet is the best choice for pregnant mamas.  But we argue that the Mediterranean diet must still be individualized and thus perfected for each woman.
