According to Dutch researcher Pascal Groenen, a balanced diet reduces the risk of a baby with spina bifida. He investigated how different nutritional components affected the risk of developing this condition.
Low concentrations of myo-inositol, zinc or vitamin B12 in the blood or a slightly elevated glucose concentration in the blood increase the risk of having a child with the congenital abnormality spina bifida.
Myo-inositol (hexahydroxycyclohexane) plays an important role in many biological processes in humans. It is produced by the human body and is also absorbed from food. Zinc is necessary for the production of proteins and therefore plays an important role in almost all metabolic processes. Vitamin B12 is important for a good functioning of the nervous system and facilitates the effect of folic acid. Zinc and vitamin B12 are very common nutrients. They are found for example in fish, eggs, milk, meat (vitamin B12) and vegetables (zinc). The research results underline the importance of a balanced diet prior to and during the initial weeks of pregnancy.
Since 1993, the Health Council of the Netherlands has advised women who want to become pregnant to take folic acid (vitamin B11) supplements in order to reduce the chance of a child with spina bifida. Groenen's research demonstrates that folic acid is not the only nutrient which plays a role in the prevention of spina bifida. Further research must show whether taking myo-inositol, zinc or vitamin B12 supplements is indeed worthwhile.
