Pregnancy and Sugar

[j.]

During the last few months of pregnancy, there is often a craving for sweet things, which should be satisfied with fruit. The potassium in fruit has an effect like that of insulin, so that sugar from the fruit can become available to cells without over-stimulating insulin secretion.

During pregnancy the mother's body adapts to live increasingly on fat, so that most of the sugar which is available can be used by the baby. The brain uses most of the body's glucose, so mental fatigue can easily affect the blood sugar level. The developing baby is extremely dependent on glucose for its energy supply, and its brain can be damaged by sugar starvation.
