Food aversions during pregnancy

By trimester

Weeks 1–13

1st trimester

This is when aversions hit hardest. Cold, bland, low-smell foods tend to go down easiest for most people. Try your prenatal vitamin with a small snack or at a different time of day if it's hard to keep down.

Weeks 14–27

2nd trimester

Aversions usually ease up as nausea fades. This is often a good time to try reintroducing protein and vegetables you couldn't stomach before.

Weeks 28–birth

3rd trimester

Aversions are less common by the third trimester. If a new food intolerance shows up this late, it can sometimes signal reflux or another digestive change worth mentioning to your provider.

What does the evidence show for food aversions?

• A varied, balanced diet plus your prenatal vitamin covers most of what your baby needs, so individual food swings usually don't need any special fix as long as your overall intake is adequate. 1
• Heightened smell sensitivity often comes along with first-trimester nausea, and it can make you avoid foods you used to enjoy just fine. 2
• Taking a vitamin supplement before and during pregnancy has been linked to less severe nausea and vomiting. 3
• Folate, iron, iodine, choline, and DHA are the nutrients that matter most during pregnancy, and a well-formulated prenatal vitamin covers these even when you're avoiding certain foods. 4

When should I call my provider about food aversions?

Aversions that start for the first time at 10 weeks of pregnancy or later are worth mentioning to your provider rather than assuming they are routine pregnancy nausea, since new-onset symptoms this late can sometimes trace back to a different cause. The same goes for aversions severe enough that they are cutting into your ability to eat, drink, sleep, or get through your day, since that level of interference crosses from a normal pregnancy nuisance into something your provider should help manage directly. None of these lists replace your own judgment: if this symptom worries you, that on its own is enough reason to check in with your healthcare provider.
