Why do periods lead to chocolate cravings?

Many people think chocolate cravings during periods are caused by hormonal changes, but new research points to culture as a bigger influence than biology. So, is period chocolate cravings a myth?

Research shows that many American women experience chocolate cravings around their period. However, according to the Washington Post, studies from the last 20 years suggest that these “period cravings” might be influenced by culture rather than biology alone. In a 2006 Cornell University study, over 300 female students were surveyed, and 91% of the American participants reported craving chocolate. For most, these cravings were strongest right before their period.

However, cravings related to the menstrual cycle seem to be less common in other cultures. In a 2006 study, only 28% of Spanish female students reported craving chocolate during their periods, while nearly half of American women did. A 2019 study revealed that most  Japanese women craved rice, while only 19%  preferred chocolate.

Scientists have explored how hormones affect chocolate cravings during menstruation. They thought that a drop in progesterone before a period might trigger these cravings. However, studies measuring hormone levels found no strong connection to chocolate cravings. A study from the University of Pennsylvania revealed that postmenopausal women who don’t experience the same hormonal changes still crave chocolate, but not as intensely as women who have their periods.

Researchers have proposed that chocolate cravings may serve as a culturally approved coping mechanism for stress, especially in the United States. A 2017 study found that women born outside the U.S. were less likely to crave chocolate around their periods. Among those who did report cravings, many were more integrated into U.S. culture and less identified with their native culture.

Dr. Julia Hormes, a psychologist who studies eating habits, explains that cravings are complicated. They often come from our emotions, not just from needing food. “Food cravings are shaped by many things, like stress, how we feel, and what society tells us,” Hormes says.

Experts aren't sure why women crave chocolate during periods, but they recommend paying attention to strong cravings. If these cravings come with severe cramps, bloating, or mood swings, it's better to see a doctor. This can help uncover any underlying health issues.
