ABC reported on October 10, 2013, that pregnant women should limit their caffeine to a daily amount of about 200 MG per day. The amount of 200 mg is the same amount that the March of Dimes has been recommending for a year now. They stated that reduced caffeine usage in pregnancy will reduce stillborn and miscarriage risks.
The March of Dimes Institute has advised expectant mothers to limit caffeine to 200-300 milligrams a day. That is equal to a 12 oz. cup of coffee. Caffeine is in more products than coffee and soda. Chocolate and select cereals also contain caffeine.
In 2008, a study was published that stated that women who consumed more than 200 milligrams of caffeine more than doubled their miscarriage risk in the first trimester. Another studied found that women who consumed more than 1800 milligrams of caffeine or eight coffees a day had twice the risk of a stillborn birth. There are other risks to excessive caffeine intake such as lower birth weight, increased heart rate and irritability.
The only true safe level of caffeine intake is none. Experts agree that is acceptable for a pregnant woman to consume a moderate amount of caffeine. So if you enjoy a cup of coffee in the morning, it is safe to continue with your cup of Joe. If the caffeine content concerns you, a good alternative would be to switch to decaffeinated coffee.
