Food Aversions
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.
Common Causes
- 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
Remedies That May Help
Eat What You Can Tolerate
In the first trimester, survival eating is acceptable. Crackers, toast, and bland carbohydrates are common safe foods.
Avoid Triggering Smells
Cold foods produce fewer odors than hot foods. Ask others to cook if cooking smells trigger aversions.
Find Substitute Proteins
If meat is intolerable, try beans, lentils, dairy, eggs (if tolerated), nut butter, or tofu as protein sources.
Small, Frequent Meals
An empty stomach worsens nausea and aversions. Keep neutral snacks available.
Prenatal Vitamins
If food aversions are limiting your diet, a quality prenatal vitamin helps fill nutritional gaps.
When to Call Your Doctor
- Aversions are so severe you cannot eat any nutritious food and are losing weight
- You are unable to find any tolerable foods after multiple weeks
- Aversions are accompanied by severe nausea and vomiting (possible hyperemesis gravidarum)
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.
Can I develop aversions to foods I used to love?
Yes — it is very common for women to develop sudden repulsion to foods they previously enjoyed, including coffee, favorite proteins, or even their own perfume.
