Guide | Understanding Pregnancy Cravings: How Science Explains Pickles, Ice Cream, and More
Late-night trips for pickles and ice cream are more than an urban legend. Many pregnant women experience sudden cravings and food aversions, and science has yet to explain the phenomenon fully.
New York banking executive Bob Gaviglio often went out late at night during his wife’s pregnancy to find chocolate honey-dipped doughnuts in the exact flavor she wanted. “Compared with the difficulty of carrying a baby, it was a small errand,” he said. Stories like this reflect the prevalence and variety of pregnancy cravings.
Taste and Aversion: Hormones, Psychology, and Evolution
Research shows that taste and smell can become much stronger during pregnancy, making some foods especially appealing and others repellent. Elizabeth Ward, registered dietitian and author of Pregnancy Nutrition, says these comfort foods may provide psychological satisfaction, while hormonal changes are thought to provide the physiological trigger.
Jennifer Niebyl, MD, chair of obstetrics and gynecology at the University of Iowa, adds that progesterone levels are closely linked to appetite changes. Women taking the hormone for contraception or menopause treatment often report similar food preferences.
Some researchers also propose an evolutionary explanation. Biologist Margie Profet suggests that strong aversions to foods such as broccoli, chili peppers, onions, or coffee may be a natural defense against potential toxins, particularly during the critical first trimester.
A Healthy Balance: Satisfy Cravings or Limit Calories?
Doctors generally say it is fine to satisfy occasional cravings during pregnancy, but a balanced diet remains essential. Pregnant women need only about 300 additional calories a day, mainly from extra sources of calcium and protein. Indulging every craving can lead to rapid weight gain or obesity.
Bruce Bagley, MD, said bluntly: “Eating without limits could quickly take you to 400 pounds. A sensible diet is the key.”
A small number of pregnant women develop pica, a craving for nonfood items such as soil, chalk, laundry starch, or even toilet paper. Although documented since ancient times, nutritionists warn that it may indicate an underlying nutritional deficiency and should be discussed with a doctor.
Do Pregnancy Cravings Affect a Child’s Preferences?
Some mothers believe pregnancy cravings shape a child’s later tastes. Anne Pike of Illinois craved blueberries during pregnancy, and her son later loved the fruit. Experts consider this more likely to be a self-fulfilling prophecy: mothers who frequently eat certain foods naturally expose their children to them more often.
Research confirms that a fetus can perceive flavors in the uterus and prefers sweetened amniotic fluid, but foods eaten by the mother do not pass unchanged to the fetus. The only well-supported link is that children of women with severe morning sickness may prefer salty foods later in life, possibly because of dehydration during pregnancy.
Balancing Instinct and Reason
Natural aversions may help pregnant women avoid certain risks, but avoiding important sources of nutrition such as vegetables or milk can cause deficiencies. Nutritionists recommend substitutes, such as lactose-free milk, when needed.
Experts agree that eating during pregnancy need not cause excessive anxiety, but it should not be unrestricted. With a balanced diet, occasional cravings can provide pleasure and warmth in family life. As Dr. Pitkin summarized: “Eating is one of life’s pleasures, not a treatment. Once nutritional needs are met, it is fine to send your husband on the occasional midnight dessert run.”
