Green Tea May Not Be Good in Pregnancy
Interesting, green tea is so good for you, but it's possible that the compounds that make it anti-cancer may (in high doses) affect the way your body uses folate, which could lead to birth defects or other things. Not to mention caffeine, while the jury is out whether it hurts a pregnancy, doesn't seem to help, either.

Green tea is rich in antioxidants, and has a host of health benefits relating to dental health, blood sugar levels, cholesterol, and weight loss. But researchers have found, whilst examining the active constituent of green tea, the epigallocatechins, or EGCG for short, that it may affect the way the body uses folate. Folate is important for pregnant women as it prevents neural tube birth defects in babies.
The problem of green tea during pregnancy is that the EGCG molecules are structurally similar to a compound called methotrexate. Methotrexate is able to kill cancer cells by chemically bonding with an enzyme in the body called enzyme dihydrofolate reductase (DHFR). Healthy people have this enzyme also - it is part of what is called the folate pathway, which is the pathway, or steps, the body takes to transform nutrients like folate into something that can be used to support its normal functions.
