Health Benefits Of Sweet Potato During Pregnancy

Eating sweet potatoes regularly during pregnancy can provide the below nutrients to the body.

  1. Vitamin A: Consuming foods such as sweet potato that is rich in vitamin A can help in tissue maintenance, fetal growth, and also supports metabolism (5).
  1. Potassium: Pregnant women require more potassium than other women of the same age. Sweet potato contains potassium, which helps to maintain fluid balance and normalize blood pressure (6).
  1. Folic acid: Pregnant women require 400mcg folic acid a day to prevent the risk of spinal cord defects. And half a cup of sweet potatoes contains 40 to 90mcg of folic acid (7).
  1. Low GI: If you have diabetes, including low-GI foods such as sweet potatoes in your pregnancy diet can be helpful (8).

All foods should be consumed in moderation, as overdose or deficiency of nutrients in the body could cause certain side effects.

Possible Side Effects Of Eating Sweet Potatoes In Pregnancy

Excess of any nutrient could be harmful in pregnancy.  As mentioned before, women with or a history of kidney problems should limit the intake of sweet potatoes, as they have high levels of oxalate (3).

Also, check with your doctor if you can consume sweet potatoes when you are on any medication. The root vegetable can interfere with some drugs and have adverse effects on your health.

Can Sweet Potato Cause Miscarriage?

More than 15,000 IU of vitamin A in daily diet could increase the chances of abnormalities. As sweet potatoes are high in vitamin A, you should not have more than what is recommended during pregnancy (9).

So, no matter how much you crave sweet potatoes, keep a tab on their consumption to avoid excess intake.
