I can't post a link without getting permission, but if you google diet sodas pregnancy you'll find a reputable study that shows that drinking 2 diet sodas a day gives you a 38% higher chance of a premature baby, and drinking 4 diet sodas a day increases that risk to 78%.
So it's significant.
The study doesn't say how premature the babies are, and I'm certain if they were causing mid-pregnancy miscarriages warnings would be all over the place.
It's also not clear that diet sodas are the CAUSE of the premature labor - in fact, probably women who drink that many diet sodas a day also engage in a lot of unhealthy other behaviors that may be the cause.
Dont sleep on your back because it can put pressure on a major artery which can prevent blood supply to you and baby. You can lay on your left or right side, however the left side provideds optimal blood supply. As far as diet coke- the fake sugar is what is bad. A normal coke is better. I drank at least a 44 oz coke every day with my first no issues. There is nothing wrong with orange juice except for the fact it is full of sugar as are most fruit juices even the no sugar added ones. Do not diet while pregnant but you can eat healthier. Just do not limit calories as that can keep you from giving baby enough nutrition.
im sure thats only if u drink tons of it a day tho..one or 2 a day wont kill your baby a case would tho lol!
There is some thought about neurological damage, but there is real evidence that lots of diet sodas can be linked to premature birth.
Everything in moderation.
what will the diet do to the baby?
diet isn't good while pregnant. OJ is fine, they actually recommend it if baby isn't moving very much bc the sugar gives them an energy boost. Sleeping on your back cuts off circulation to your legs bc of a vein that your uterus presses on, it won't harm the baby and if your do turn onto your back, it won't really be that big of a deal. Lunchmeat is fine, just warm it up before you eat it. 600 mg of caffeine a day is "okay" during pregnancy.
I have the book, "What to expect when you're expecting" its a great $12 investment I recommend every pregnant woman getting, it answers all of these questions. :)
