Pregnancy brings about many changes in a woman’s body, both physically and hormonally. One of the most common changes is the development of food aversions. This is a phenomenon where certain foods that were once enjoyed become unappetizing or even repulsive. Understanding when food aversions start during pregnancy, why they happen, and how they affect expectant mothers can help in managing these changes better. This article will explore the timing, causes, and impact of food aversions in pregnancy.
What Are Food Aversions?
Food aversions occur when a person develops a strong dislike or avoidance of specific foods. In pregnancy, these aversions can be triggered by sight, smell, or even thought of certain foods, and may lead to nausea or vomiting. Although food aversions are commonly associated with the first trimester, they can happen at any stage of pregnancy.
Pregnancy-related food aversions are often paired with heightened sensitivity to smells and changes in taste preferences, and they may overlap with pregnancy cravings, though these are two different experiences.
When Do Food Aversions Typically Start?
First Trimester: The Most Common Starting Point
Most pregnant women report experiencing food aversions during the first trimester. In fact, the onset of food aversions is often one of the earliest signs of pregnancy, beginning as early as the 5th or 6th week of gestation. This timing correlates with significant hormonal changes in the body, particularly the rapid increase of human chorionic gonadotropin (hCG) and progesterone levels.
These hormonal shifts are thought to contribute to the nausea and vomiting commonly associated with morning sickness, which often accompanies food aversions. Many women describe an aversion to strong-smelling or strong-tasting foods such as meat, coffee, or certain vegetables during this phase.
Second Trimester: Continuing Aversions or New Ones?
While the first trimester is typically the most intense period for food aversions, some women continue to experience them into the second trimester, or may even develop new aversions at this stage. Around the 12th to 16th week of pregnancy, morning sickness usually begins to subside for many women, and with it, food aversions may also diminish. However, it’s not uncommon for certain aversions to linger or to fluctuate as the pregnancy progresses.
For those who still experience food aversions during the second trimester, the intensity of their reactions may lessen, though the specific foods that trigger the aversion often remain the same.
Third Trimester: Less Common, But Possible
By the third trimester, most women find that their food aversions have significantly decreased or disappeared entirely. However, some women may still find that they have lingering aversions to certain foods. These aversions in the final stages of pregnancy are often milder, but can still be problematic, especially if the foods avoided are nutritionally important.
Additionally, some new aversions may develop in the third trimester as a result of the growing baby pressing on the stomach, which can lead to discomfort or changes in appetite.
What Causes Food Aversions During Pregnancy?
Hormonal Changes
Hormonal fluctuations are believed to be the primary cause of food aversions during pregnancy. The surge in hormones such as hCG, estrogen, and progesterone, especially in the first trimester, can significantly alter a woman’s sense of smell and taste. These changes can make certain foods that were once appetizing seem unbearable, while the body may crave foods that help alleviate nausea or provide comfort.
Evolutionary Perspective
Some researchers believe that food aversions in pregnancy may have an evolutionary basis. The theory suggests that pregnant women may develop aversions to foods that could potentially harm the developing fetus, particularly foods that are prone to contamination, such as raw or undercooked meats. This protective mechanism would help to reduce the risk of foodborne illnesses, which can be especially dangerous during pregnancy.
Sensitivity to Smells
Pregnancy often enhances a woman’s sensitivity to smells, a phenomenon known as hyperosmia. This heightened sense of smell can trigger food aversions, particularly to foods with strong odors, such as fish, meat, and certain vegetables. The connection between smell and taste is strong, and foods that are particularly pungent can become intolerable during pregnancy.
Emotional and Psychological Factors
Pregnancy can be an emotional time, and stress or anxiety may also contribute to food aversions. Emotional changes, mood swings, and pregnancy-related fatigue can make certain foods seem less appealing. In some cases, women might associate specific foods with feelings of nausea or discomfort, leading to a psychological aversion that persists even after the initial symptoms subside.
Common Foods Pregnant Women Develop Aversions To
While food aversions can vary widely between individuals, there are certain foods that many pregnant women report having aversions to:
Meat: Due to its strong smell and taste, meat is a common food aversion, especially red meats or fatty cuts.
Seafood: The smell of fish and shellfish is often unbearable for pregnant women, particularly in the first trimester.
Eggs: Many women report an aversion to the texture or smell of eggs.
Dairy Products: Some women develop aversions to milk, cheese, or yogurt, particularly if they have a strong flavor or smell.
Spicy Foods: Foods with intense heat or spices may become intolerable, especially if they exacerbate pregnancy-related heartburn or indigestion.
Vegetables: Certain vegetables with strong or bitter flavors, such as broccoli, Brussels sprouts, and cauliflower, are often disliked during pregnancy.

Managing Food Aversions in Pregnancy
Eat Small, Frequent Meals
Eating smaller, more frequent meals throughout the day can help manage food aversions and reduce the likelihood of nausea. This approach can also help ensure that you’re getting enough nutrients even if you’re avoiding certain foods.
Experiment with Different Food Preparations
Sometimes, changing the way a food is prepared can make it more tolerable. For example, if the smell of cooking meat triggers an aversion, trying it cold in a salad or sandwich may be more manageable. Steaming or boiling vegetables may help lessen their strong odor and make them more palatable.
Focus on Nutrient-Rich Foods You Can Tolerate
It’s important to maintain a balanced diet during pregnancy, so if certain food groups are causing aversions, try to find alternative sources of essential nutrients. For example, if meat is unappealing, plant-based proteins such as beans, lentils, and tofu can be good alternatives.
Stay Hydrated
Sometimes, food aversions are accompanied by nausea and vomiting, which can lead to dehydration. Drinking plenty of water and staying hydrated is crucial during pregnancy. If plain water is difficult to tolerate, try adding a slice of lemon or ginger to improve the flavor.
When to Seek Help for Severe Aversions
While food aversions are a normal part of pregnancy for most women, severe or prolonged aversions that interfere with proper nutrition should be addressed with a healthcare provider. If a woman is unable to eat a balanced diet or is losing weight, her doctor or midwife may recommend dietary supplements or alternative strategies to ensure she and her baby are getting the necessary nutrients.
Conclusion
Food aversions are a common and often frustrating part of pregnancy, but they are usually temporary and manageable. They typically start in the first trimester, with many women experiencing them as early as five or six weeks into their pregnancy. Hormonal changes, heightened senses, and emotional factors all contribute to the development of aversions, and while they can be uncomfortable, they usually subside as the pregnancy progresses.
By understanding when food aversions start and how to manage them, expectant mothers can navigate this aspect of pregnancy with more ease, ensuring they and their baby remain healthy throughout the journey.
