People love green tea, and as talks about coffee and fertility go back and forth on whether or not it is ok, or caffeine in general, people chose to opt for green tea instead. But just how much are you drinking? A new study from the Journal of Functional Food is saying that dose may be an important factor.
The study was just done with fruit flies, where embryos and larvae were subjected to various doses of green tea polyphenols, but in those experiments the team from University of California-Irvine discovered that excessive consumption adversely affected development and reproduction in fruit fly populations. What is excessive consumption? While tea seems to have benefits at low dosages, higher dosages, perhaps more than a cup a day, may not be such a great idea if you are TTC (trying to conceive). Many products are under regulated, and teas and coffees should be avoided unless they are organic and used in low dosages.
If one does get pregnant, many doctors advise to reduce or cut caffeine completely for the first 10-12 weeks, and this might include green tea now. More studies need to be done to know for sure how these typical American morning beverages can effect fertility, conception and pregnancy. Future studies will include measuring total consumption and dosing to help quantify the metabolites of natural products in the fruit flies.
