Pregnancy nutrition: Foods to avoid during pregnancy

Don't have too much caffeine

Caffeine can cross to the baby, but the effects on the baby aren't clear. To be safe, your health care professional might tell you not to have caffeine while pregnant. Or you may be told to limit caffeine to less than 200 milligrams (mg) a day.

An 8-ounce (240-milliliters, or mL) cup of brewed coffee has about 95 mg of caffeine. An 8-ounce (240-mL) cup of brewed tea has about 47 mg. And a 12-ounce (360-mL) cola with caffeine has about 33 mg.
