“I’d advise pregnant girls to soak up as little caffeine as attainable and change to decaf altogether if they’ll,” Foxe mentioned.

However he urged girls to not go chilly turkey in the event that they may also help it, as a result of caffeine withdrawal could cause a number of signs, together with complications, irritability, nausea and problem concentrating.

“We do not know what withdrawal, irritability, stress and nervousness will do to a being pregnant,” Foxe mentioned. “Attempt to whittle away at your caffeine consumption earlier than you get pregnant.”

The research does have some limitations. Girls had been requested to recall how a lot caffeine they consumed whereas pregnant, and reminiscence is not at all times 100% correct.

The findings had been just lately printed on-line within the journal Neuropharmacology.

“Pregnant girls will be fairly reassured that consuming lower than 200 milligrams per day of caffeine is not going to trigger miscarriage or preterm start,” he mentioned. However extra research is required on the way it impacts baby improvement, Klebanoff added.

“A typical cup at house has about 100 mg of caffeine, so girls can restrict themselves to 2 cups a day when pregnant,” he mentioned.

However they need to remember the fact that different sources of caffeine (corresponding to vitality drinks, energy bars and chocolate) must be thought-about as a part of the full, Klebanoff mentioned.
