Food Aversions at 27 Weeks Pregnant

Food aversions — sudden repulsion to foods or smells that were previously tolerated — affect over 80% of pregnant women, most intensely in the first trimester. They often develop alongside morning sickness.

👶 What's Happening at Week 27

Your baby is now the size of a rutabaga.

  • The brain develops more grooves and indentations for increased brain tissue.
  • The fetus sleeps and wakes at regular intervals.
  • Lungs continue maturing but are not yet ready for breathing air.

🔬 Why You're Experiencing Food Aversions at Week 27

  • Rising hCG and estrogen enhance smell and taste sensitivity dramatically
  • Protective mechanism theory: the body may reject foods associated with spoilage risk (meat, eggs, poultry)
  • Associated with nausea — foods that trigger nausea become aversions
  • Neurological changes in smell and taste processing during early pregnancy

💊 Relief Tips for Week 27

1
Eat What You Can TolerateIn the first trimester, survival eating is acceptable. Crackers, toast, and bland carbohydrates are common safe foods.
2
Avoid Triggering SmellsCold foods produce fewer odors than hot foods. Ask others to cook if cooking smells trigger aversions.
3
Find Substitute ProteinsIf meat is intolerable, try beans, lentils, dairy, eggs (if tolerated), nut butter, or tofu as protein sources.
4
Small, Frequent MealsAn empty stomach worsens nausea and aversions. Keep neutral snacks available.
5
Prenatal VitaminsIf food aversions are limiting your diet, a quality prenatal vitamin helps fill nutritional gaps.

Frequently Asked Questions

What are the most common food aversions in pregnancy?

The most commonly reported aversions are to meat (especially chicken and beef), eggs, seafood, garlic, onions, spicy foods, coffee, and alcohol.

Do food aversions indicate the baby's gender?

There is no scientific evidence that specific food aversions indicate the baby's sex, despite the popular theory that aversions to meat predict girls.

When do food aversions go away?

Most food aversions resolve by the end of the first trimester (weeks 12–14), though some persist into the second trimester.

Can food aversions cause nutritional deficiencies?

If aversions are severe and prolonged, they can limit nutrient intake. A prenatal vitamin and guidance from a registered dietitian can help ensure nutritional adequacy.
