Potatoes 'pose pregnancy diabetes risk'
Eating potatoes or chips on most days of the week may increase a woman's risk of diabetes during pregnancy, say US researchers.
This is probably because starch in spuds can trigger a sharp rise in blood sugar levels, they say.
Their study in the BMJ tracked more than 21,000 pregnancies.
But UK experts say proof is lacking and lots of people need to eat more starchy foods for fibre, as well as fresh fruit and veg.
The BMJ study linked high potato consumption to a higher diabetes risk.
Swapping a couple of servings a week for other vegetables should counter this, say the authors.
UK dietary advice says starchy foods (carbohydrates) such as potatoes should make up about a third of the food people eat.
There is no official limit on how much carbohydrate people should consume each week.
Foods that contain carbohydrates affect blood sugar.
Some - high Glycaemic Index (GI) foods - release the sugar quickly into the bloodstream.
Others - low GI foods - release them more steadily.
Research suggests eating a low GI diet can help manage diabetes.
Pregnancy puts extra demands on the body, and some women develop diabetes at this time.
Gestational diabetes, as it is called, usually goes away after the birth but can pose long-term health risks for the mother and baby.
The BMJ study set out investigate what might make some women more prone to pregnancy diabetes.
The study followed nurses who became pregnant between 1991 and 2001. None of them had any chronic diseases before pregnancy.
