B vitamines en zwangerschap?*
Uit een Engelse studie, weliswaar met schapen, blijkt dat bij te weinig vitamines
B12 en foliumzuur op het moment van conceptie nakomelingen geeft die binnen een paar jaar al tekenen vertonen van insuline resistentie, 25% dikker zijn en een hogere bloeddruk hebben. Hierdoor hebben ze een grotere kans later op hart- en vaatziektes en diabetes.
Meer onderzoek is nodig om te kijken of deze resultaten ook voor mensen gelden.
Vitamin B Deficiency In Pregnant Mothers Linked To Diabetes
Babies whose mothers do not get enough essential B vitamins around the time of conception could be more at risk of Type 2 diabetes.
A study of female sheep showed that reducing their intake of B12 and folate (a form of vitamin B9) before pregnancy produced major physical effects in their
offspring.
At only two years of age, the sheep showed signs of insulin resistance and were 25 per cent fatter than normal with higher blood pressure.
Scientists say there is a greater chance of these sheep developing Type 2 diabetes and becoming obese, and they are more at risk of heart
disease.
The findings were published in the Proceedings of the National Academy of Sciences.
"This is an interesting new study but it is very early days yet, as it has only been undertaken with animals," said Caroline Butler, Care Advisor at Diabetes UK.
"Much more research is required before we can see if the results would be replicated in humans."
Vitamin B12 is essential for the synthesis of red blood cells and the maintenance of a healthy nervous system. It can be found in red meat, eggs and dairy products.
