Word Count:
552

Summary:
Pregnant women should limit the amount of green tea they drink during pregnancy. This article discusses why, as well as providing a guideline on how much coffee and tea can be safely drunk without significantly affecting the birth weight of your baby, or increasing the chance of miscarriage or stillbirths.


Keywords:
green tea side effects, green tea health, healthy pregnancy, prenatal nutrition


Article Body:
Pregnant women would be wise to limit the amount of green tea they drink during pregnancy, and should be careful about taking any green tea supplements. 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.

But this chemical similarity means 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 ability of the body to use folate is going to be affected. How much green tea is able to be consumed, or precisely how much folate absorption is affected, is unclear. Though the research 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 good news on caffeine drank during pregnancy, from coffee and tea, is that a moderate amount is fine. Two studies, one by Danish scientists who interviewed more than 88,000 pregnant women, and the other by the Yale University School of Medicine, had similar findings on caffeine during pregnancy.

The concerns over caffeine were that it would lead to low birth weight or miscarriage. And this is still true of a very high daily 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 per day. But they emphasized that this would not be significant for moderate caffeine consumption.

The Danish study found that drinking 8 cups or more of coffee per day (this would be about 16 cups or more of tea), would increase the chances of miscarriage, or stillbirth, by 60% compared to women 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 3 cups of coffee a day, the risk of fetal death was 3% higher compared to non-caffeine drinkers. And for those drinking 4 to 7 cups of coffee a day, the risk increases to 33%. One cup of coffee equals about 2 cups of tea when comparing caffeine levels. The recommended amount of coffee drunk is up to 3 cups daily, or 6 cups of tea, by the UK food agency.

BONUS : Preparing the kids for Pregnancy

The moment you find out your pregnant you want to tell everyone, including your kids. The way you tell your child depends on their age, an older child will understand what it means when you tell them you are pregnant or that they are going to be a brother or sister soon. However, a toddler is a little bit harder to explain this too.

Think about your child’s personality when it comes time to tell them. You know your child best. They may enjoy being sent little clues like you did with daddy, or they may just want you to tell them straight out. You could get lucky and have them walk in the room while you are announcing it. This happened to me when I was expecting child number four. I had just walked out of the bathroom waving the wand in the air to show my husband. I had no clue that my kids had walked into the room until I heard them screeching I was pregnant. Oops.

Their Reactions
Don’t be shocked if at first your child acts distant, many children will respond to the news in their own way. One of your children may even start to pretend to be pregnant right along with you, mimicking everything you do. While another child may tell you they don’t want you to bring home a new baby. These are all common reactions to the news, the way you handle it will determine the outcome.

If your child seems reluctant to want another child in the home you may want to find out why. The only way to find out what’s bugging him/her is to ask. Maybe they are just scared that you are going to stop loving them, or that everyone will forget about him/her when the baby is born.

Showing them They are Important too
A good way to do this is to make sure they get something the moment the baby is born, some have had the doctors give the sibling their own baby doll when their sibling was born. Try reading children’s books with them to show them that it’ll be a good thing. Dad can always spend some one on one time with them.

Involving Your Child in the Pregnancy
This is their baby too, have your children accompany you to a few of the doctor visits. Let them hear the heartbeat of their little sister or brother. Watch their faces light up when they see the baby for the first time on the screen. There are many ways you can involve them, you can encourage them to help you decide on a name. Try letting them feel the baby kick for the first time by placing their hand on your swollen belly.

It’s easy to prepare the siblings for your new arrival as long as you involve them in the pregnancy along the way. They’ll be happy to be part of it and feel more of a connection to the baby when he/she is born.
