Green Tea during first trimester pregnancy harmful?

Answered on August 19, 2014
Created August 10, 2011 at 4:01 PM

So, I'm trying get pregnant, and I recently began reading the book "Your Pregnancy, Week by Week." In the book they talk about the dangers of green tea during the first trimester of pregnancy, and recommend stopping green tea at least 3 months before you even try and get pregnant. So I Googled this and found that other sources are advising the same thing, or they are saying not to worry.

So why no green tea? It decreases the efficacy level of folic acid which is harmful for baby as folic acid plays a very important role in protecting neural tube defect soon after conception in the first month. It's the epigallocatechin molecules affect the way the folate is used by the body.

Now, I am a loose leaf green tea drinker, and I've had about 1-2 cups a day, for the past 1.5 years.

Can anyone offer any insight into this? I'm at a loss of whether or not this claim is true, and if I should give up my green tea.

Also, would Coconut milk be a better substitute? I'm not sure if there are any other foods/drinks that could better help my body prepare for pregnancy. I've been strict Paleo for about 2 months now.

+1 for liver. Organ meats have been traditionally promoted for couples trying to conceive. Make sure the future baby-daddy is getting enough zinc too, to make sure the little swimmers are good and strong.

It does, but it is not a significant amount if she is keeping her intake to 2 cups or less. Both green & black teas vary in their caffeine content, so if she goes for a black tea, she can make it very weak or find one that is low in caffeine. From Wiki: Black tea, 6 oz approx 50 mg caffeine Green Tea, 6 oz approx 30 mg caffeine

Looks like the claim is true:

I would definitely give up your green tea & replace it with a weak black tea, if you really need to. As long as you don't drink more than 2 cups your caffeine levels should be fine.

Coconut milk is great! Water is fantastic.

Eating liver regularly is a great way to make sure you get plenty of folate.

My advice to moms trying to conceive is that you eat the same foods you would if you were already pregnant.

Here's a blog post I wrote recently on Primal Pregnancy nutrition.

I would stay away from green tea - just to be safe - especially since you are having a tough time becoming pregnant.

Have you tried accupuncture? I have had 2 friends that had one and 2 year struggles with infertility that tried accupuncture and both became pregnant within a cycle or two. I beleive they went the whole Chinese medicine route and were both sceptical to begin but blown away with the results.

I'm so sorry to hear of your struggles with fertility. Hang in there - it will happen! And bank as much sleep and as much one on one date time with hubby as you can now because once your pregnant and have a little one you'll wish you had! GOOD LUCK!

You need optimal folic acid levels in your body before you conceive because much of the neural tube development takes place in the days before you're even aware you have conceived. So yes, I'd ditch the green tea. Susun Weed is pretty much accepted as the authority on herbs during pregnancy and childbirth; she has a number of books that may be helpful to you.

My thought would be that if it's the least bit controversial then go without it. It's just not worth the risk.

In addition to the aforementioned, you'd be blocking some amount of dietary iron absorption and getting a fairly heavy dose of fluoride (which camellia sinensis bioaccumulates to a huge extent).

I can't imagine that exposing a fetus to any sort of exogenous stimulant is optimal as well.
