The Effects of Caffeine and Green Tea on Prenatal Nutrition

During pregnancy, it is recommended that pregnant women restrict their use of green tea and exercise caution while using any green tea supplements, which are available. Green tea is high in antioxidants and offers a slew of health advantages, including benefits for dental health, blood sugar levels, cholesterol, and weight reduction, among others. Researchers, however, discovered that the main element of green tea, epigallocatechin, or EGCG for short, may have an effect on the way the body utilizes folate when studying the key constituent of green tea. Folate is essential for pregnant women because it helps to prevent neural tube abnormalities in newborn newborns.

The difficulty with drinking green tea during pregnancy is that the EGCG molecules are chemically identical to a drug known as methotrexate, which may cause birth defects. Methotrexate has the ability to destroy cancer cells by forming a chemical link with an enzyme in the body known as the enzyme dihydrofolate reductase (DHFR). Regular-functioning individuals also possess this enzyme, which forms part of what is known as the folate pathway, which is the route, or series of steps, that the body uses to convert nutrients such as folate into something that can be utilized to maintain its normal activities.

As a result of this chemical resemblance, the EGCG found in green tea may similarly attach to the enzyme DHFR, and when it does so, the enzyme is rendered inactive. Because of the inactivation of this enzyme, the body's capacity to use folate will be impaired. Whether or whether green tea can be eaten in large quantities, as well as how much folate absorption is altered, is currently unknown. However, according to the study report, consuming two cups of green tea every day may prevent cancer cells (which is what methotrexate is targeting) from developing and spreading.

The good news about caffeine use during pregnancy, whether it comes from coffee or tea, is that a reasonable quantity is perfectly safe. In two studies on caffeine use during pregnancy, one conducted by Danish scientists who interviewed more than 88,000 pregnant women and the other conducted by the Yale University School of Medicine, researchers came to identical conclusions.

One of the main worries about caffeine was that it may cause low birth weight or miscarriage in pregnant women. And this is still true for those who consume a large amount of coffee on a regular basis. It was discovered by the Yale team that consuming around 600mg of caffeine per day (equivalent to approximately 6 cups of coffee) might lower birth weight to levels that were clinically relevant. The rate at which birth weight was lowered was determined to be 28 grams per 100 milligrams, or one cup, of coffee, consumed every day, according to the research. However, they stressed that this would not be significant for those who use modest amounts of caffeine.

According to the findings of the Danish research, consuming 8 cups or more of coffee per day (equivalent to 16 cups or more of tea) increased the odds of miscarriage or stillbirth by 60% when compared to women who did not consume caffeine. They also discovered that consuming modest amounts of coffee or tea did not offer any substantial dangers. The risk of fetal mortality was 3 percent greater for individuals who had half a cup to three cups of coffee per day compared to those who did not consume caffeine. And the risk jumps to 33 percent for individuals who consume 4 to 7 cups of coffee every day, according to the study. When it comes to caffeine content, one cup of coffee is about equivalent to two cups of tea. According to the United Kingdom Food Agency, a maximum of three cups of coffee or six cups of tea per day is suggested.
