Pregnant ladies could be wise to limit the amount of green tea they drink throughout pregnancy, and should be careful about taking any green tea supplements. Green tea is rich in antioxidants, and has a host of health advantages concerning dental health, blood sugar levels, cholesterol, and weight reduction. But scientific study has found, whilst examining the active constituent of green tea, the epigallocatechins, or EGCG for short, that it may have a bearing on how the body uses folate. Folate is important for pregnant women as it prevents neural tube congenital anomalies in babies.
The difficulty of green tea during pregnancy is that the EGCG molecules are structurally similar to a compound known as methotrexate. Methotrexate can kill cancer cells by chemically bonding with an enzyme within the body referred to as enzyme dihydrofolate reductase (DHFR). Healthy people have this enzyme also - it is component of what's remarked as the folate pathway, that is the pathway, or actions, the body takes to transform nutrients like folate into something that could be utilized to support its regular functions.
But this chemical similarity suggests that the EGCG in green tea also binds with the enzyme DHFR, and when it does this, it inactivates this enzyme. When this enzyme is inactivated, the capacity of the body to use folate is likely to be affected. The amount of green tea can the exhausted, or precisely what amount of folate assimilation is affected, is unclear. Though the study article did say that drinking 2 cups of green tea a day can stop cancer cells ( which is what methotrexate is targeting) from growing.
The great news on caffeine drank in the middle of pregnancy, from coffee and tea, is that a moderate amount is fine. Two studies, 1 by Danish scientists who interviewed a lot more than 88,000 pregnant women, and the other by the Yale University School of Medicine, had comparable findings on caffeine among pregnancy.
The concerns over caffeine had been that it would result in low birth weight or miscarriage. And this is still true of a quite high every day intake of coffee. The Yale team found that drinking about 600mg of caffeine a day, which is about 6 cups of coffee, would reduce birth weight to levels that were clinically significant. The rate at which birth weight was reduced was established at being 28 grams per 100 mg, or 1 cup, of coffee each day. But they emphasized that this wouldn't be significant for moderate caffeine ingestion.
The Danish study found that drinking 8 cups or more of coffee a day (this would be about 16 cups or a great deal more of tea), would boost the prospects of miscarriage, or stillbirth, by 60% compared to ladies who did not drink caffeine. They also found that moderate coffee or tea drinking did not pose significant risks. For those drinking half a cup to three cups of coffee a day, the chance of fetal death was 3% higher in comparison to non-caffeine drinkers. And for those drinking 4 to 7 cups of coffee a day, the risk increases to 33%. 1 cup of coffee equals about 2 cups of tea when comparing caffeine levels. The suggested quantity of coffee drunk is up to 3 cups daily, or 6 cups of tea, by the UK food agency.
