A study shows that women who drink high amounts of caffeine have a more of a chance to miscarry. Over the years many studies have linked caffeine to decreased fertility. Women that drank 200mg or more caffeine had a 25% chance of having a miscarriage. Doctors have recommended for years that women who plan on becoming pregnant and those that are pregnant reduce their caffeine consumption. Caffeine is not just found in coffee, but also from tea, soda, and chocolate. The amount in one cup of coffee is a lot more than from other sources.
In the study researchers used the following conversion for determining the amount of caffeine in each 150mL beverage (approximately 5.07 fl oz.)
- Caffeinated coffee -100mg
- Decaffeinated coffee-2mg
- Caffeinated Tea-39mg
- Caffeinated Soda-15mg
- Hot Chocolate -2mg
