A study has found that 54% of pregnant women experienced food aversions during early pregnancy (1). The condition could occur at any stage of pregnancy, but it is more likely during early pregnancy or the first trimester. This feeling of disgust towards certain foods may go away as the pregnancy progresses or after you deliver (2).

If you have given up eating certain foods important for your pregnancy diet due to food aversion, introduce them later in your pregnancy to check if the aversion has passed (13).

What Causes Food Aversions During Pregnancy?

The exact cause of food aversion or appetite loss in pregnancy is not known, but researchers have a few theories.

  1. Hormonal fluctuations: Just like the behavioral and physiological changes during pregnancy, food aversions could also be due to hormonal changes. However, there is no connection between food cravings and aversions.

The human gonadotropin (hCG) hormone produced during pregnancy may cause nausea, appetite changes, and food aversion (13).
  1. Morning sickness: Nausea is more common during the early months of pregnancy and could be responsible for food aversions. For instance, just the smell of certain foods can make you feel nauseated (3).

  1. Sensitivity to taste and smell: During pregnancy, a woman’s senses are heightened. Abnormally increased taste and smell sensitivity could stop you from having any foods. For instance, sensitivity to a bitter taste may prevent you from having tea, coffee, or chocolate (4).
  1. Maternal-embryo protection hypothesis: It states that certain mechanisms don’t allow pregnant women to have foods that contain toxins or pathogens. It is to protect the woman and her baby. This could also be a cause for food aversions (5).

But what foods could you become averse to? Can you even eat anything? Find out more about it next.

All pregnant women are not repulsive to the same foods. Food aversion depends on several factors and varies accordingly. But in general, most pregnant women tend to be averse to these foods.

  1. Spices or spicy foods: You may be averse to hot and spicy foods especially during the first trimester when you have nausea and vomiting (6).
  1. Caffeine: Pregnant women may also have an aversion to caffeine. According to a study on caffeine consumption, 65% of the women had expressed their aversion to drinking coffee when they were pregnant (7). Some expectant mothers reduce the intake of tea too.

Bailey Gaddis, a mom, a birth doula, a childbirth preparation educator, and a hypnotherapist, shares her food aversion during pregnancy, “I absolutely have no craving for sweets.

Frequently Asked Questions

1. Can food aversions predict gender?

2. Are food aversions more common with baby boys?

No reliable studies link food aversions to a baby’s gender. However, food aversions can be closely related to the pregnant woman’s dietary intake. Thus, aversions may predict the maternal nutritional status more than gender (10) (11).

3. Do food aversions go away with pregnancy?

Food aversions and avoidance are common in the first trimester and may be caused by taste changes during pregnancy. In most cases, it gradually improves during the last trimester and goes away after pregnancy (12).

4. Is it safe to eat foods that are causing food aversions during pregnancy?

Food aversions tend to subside by around 14 weeks. Therefore, if you don’t feel like eating certain foods initially, you may avoid them and try again later in your pregnancy to see if the aversion has passed (13).

5. Are there any health risks associated with food aversions during pregnancy?

Common food aversions during pregnancy are not considered harmful to maternal and fetal health. However, if you are experiencing nausea and vomiting and not getting enough nutrients or losing weight, you should consult your doctor (13).

6. Are there any treatments available for food aversions during pregnancy?

Vitamin B6 and Doxylamine may help alleviate morning sickness and ease some of your food aversions (14). However, you should avoid self-medication and consult a doctor if you wish to take any medication.

It is normal to have food aversions during pregnancy. Some women may not like the taste of their favorite foods during pregnancy. Most pregnant women experience food aversions in the early weeks of pregnancy. While a few may have it throughout their pregnancy.

You may plan a pregnancy diet with balanced nutrition and alternative sources of nutrition. Most women may also develop aversions to coffee, or other caffeinated beverages, poultry, meat, and spicy foods during pregnancy.
