Question

Drinking caffeine while pregnant will resort to deformity

Answer 1

Summary:

There is no concrete evidence that proves that drinking caffeine while pregnant causes deformity. My sources explained how caffeine could cause more subtle side effects such as increased heart rate or disruption of fetus growth; however, there is no direct proof that drinking caffeine leads to deformity. Additionally, the National Library of Medicine goes even further and explains how drinking caffeine while pregnant in moderation actually has no effects whatsoever on a pregnancy. They even state how 70% of women admit to still consuming caffeine while pregnant. The American Pregnancy Association agrees with the National Library of Medicine by also explaining how caffeine could cause side effects but only when it comes to extremely high intakes. So, overall, there has been no evidence that supports this exact claim.

Answer 2

Since there is no source to back the claim and from research given about this topic it easy to say the statement is false/ too broad of a claim. The only effect that could happen to the fetus in the womb is stunt its growth as the child grows up which studies such like ECHO, Child Health Outcomes, and CCP, Collaborative Perinatal  Project, resulted in less than 2 cm in height growth from women consuming a bigger amount of caffeine than to children to woman that had little to none.

Another article concludes that the consumption of alcohol is generally safe as long done in moderation. But if abused then the parents will see their child having developmental issue down the road is it grows up.
