There is no official advice that says you should stop drinking green tea during pregnancy. So there’s no harm in enjoying a cup or two.
However, you shouldn’t drink too much green tea, as it contains only a little less;caffeine;than standard tea, depending on how it’s brewed.
Keep to a limit of 200mg of caffeine a day, which is about three or four cups of green tea. This 200mg limit should include all sources of caffeine though, so count coffee, soft drinks, cola, energy drinks, and chocolate in your daily amount.
Green tea is thought to be a health-promoting drink, because it’s rich in antioxidants. Antioxidants are chemical compounds that can help to prevent cell damage in our bodies and may even help to protect against heart disease,;high blood pressure;and type two diabetes.
Drinking green tea may also be good for your teeth and bones, and help you to maintain a healthy immune system.
However, drinking a large amount of green tea may prevent you from absorbing;folic acid;properly. Folic acid is an important;nutrient, particularly during the first 12 weeks of your pregnancy. It can prevent neural tube defects such as;spina bifida.;
Because green tea reduces the folic acid you absorb, drinking lots of it around conception has been linked to a higher risk of babies developing neural tube defects. However, the risk to your baby is still low so try not to worry if you’ve already had green tea around the time your baby was conceived. It’s unlikely that you would have had so much green tea that it would harm your baby.
Bear in mind that green tea, like other teas, can also make it difficult for your body to;absorb iron from non-meat foods. So it’s best not to drink it with meals.
