Why Should You Avoid Eating Fish During Menstruation?

A woman’s body undergoes significant changes during menstruation. Immune function tends to decline, making it especially important to take proper care of oneself—particularly by staying warm. Dietary choices also require extra caution; cold or cooling foods should be avoided. So, can women eat fish during their period?

Why Can’t Women Eat Fish During Menstruation?

The term “menstrual period” refers specifically to the days when a woman is menstruating. However, there is no scientific evidence indicating that women should avoid eating fish during this time. In fact, consuming fish during menstruation can benefit overall health and does not interfere with menstrual flow or cycle.

Most women experience reduced immunity during menstruation. Fish is rich in high-quality protein, essential amino acids, and various trace elements. Eating moderate amounts of fish during this time helps replenish vital nutrients and strengthens immune function. Moreover, fish consumption does not affect menstrual volume or cycle regularity. Conversely, raw, cold, or spicy foods—such as chili peppers, ice cream, and popsicles—should be avoided, as they may trigger or worsen dysmenorrhea (painful menstruation).

If dysmenorrhea occurs, applying a hot water bottle to the lower abdomen can improve blood circulation and help alleviate pain. For severe pain, ibuprofen sustained-release capsules may be taken under a physician’s guidance. During menstruation, women should maintain a light, balanced diet and practice good hygiene—washing the external genitalia daily with warm water and changing underwear frequently.

Fish is a high-protein food that helps counteract the fatigue and weakness often associated with menstruation and supports immune resilience. Women should avoid raw, cold, or spicy foods during their period—including ice cream, chilled beverages, and chili peppers. Additionally, keeping the body warm is essential; exposure to cold water or cold environments should be minimized, as these may provoke dysmenorrhea or disrupt menstrual regularity.
