Low energy is a common pregnancy-related complaint, but before reaching for a cup of coffee for a java jolt, it is important to understand how much caffeine is recommended during pregnancy. The American Congress of Obstetricians and Gynecologists (ACOG) recommends limiting your caffeine intake to no more than 200mg per day, which is equal to about one 12 oz cup of coffee. Here’s why:
Caffeine impacts both you as well as your growing baby. For moms, caffeine’s a diuretic as well as a stimulant, meaning that it both increases urination, as well as negatively impacts your ability to fall and stay asleep. As frequent urination and difficulty sleeping are common pregnancy complaints, it is important to consider your caffeine intake if you are struggling with either or both of these. Because caffeine travels straight through the placenta, your baby may experience its known side effects as well, including: shakiness, jitters, increased heart rate, possible uneven heart rate, elevated blood pressure, dependency, and difficulty sleeping.
Which foods and beverages contain caffeine? In addition to coffee (both regular and decaf), caffeine is also present in:
A word on green tea – not only does green tea contain some caffeine, but it can also limit your body’s absorption of folic acid. This B vitamin is critical during pregnancy as it promotes the proper development of an unborn baby’s neural tube, which later becomes the brain and spinal cord. Although the strength of the connection between green tea and folic acid is unclear, it may be best to limit your green tea consumption to 1-2 cups per day.
Here’s a cheat sheet identifying the average amount of caffeine in common foods and drinks. You may want to keep this handy as you calculate your 200mg per day:
Always read the ingredients list to check whether caffeine is hiding in your favorite foods. Increasingly popular “energy foods” like gum, mints, sunflower seeds, energy bars, waffles, jerky and even oatmeal can contain caffeine.
Limit caffeine to no more than 200mg per day
Remember to add up all sources of caffeine – from food, beverages and medications – to make sure that you’re not exceeding the 200mg per day limit.
Consider your sleep schedule
If you have trouble sleeping through the night or wake up frequently to urinate, avoid caffeine in the afternoon and evening.
Avoid energy drinks
Limit green tea
If you drink green tea, have no more than 1-2 cups per day (and remember to factor it into your total caffeine intake).
Be a detective!
Read labels to understand whether the foods and beverages you consume contain caffeine.
Consult with your healthcare provider or pharmacist to understand caffeine levels in medications
Rest up!
If you’re feeling exhausted, make sure to get plenty of rest. Instead of reaching for a cup of joe, find time for light exercise and fuel your body with the fruits, vegetables, whole grains, lean protein, beans and nuts it needs to support you and your growing baby.
