There is little scientific support for a link between food cravings and the menstrual cycle. There have been suggestions that chocolate cravings during menstruation are related to a deficiency of magnesium or are linked to carbohydrate consumption to self-medicate depression, but no strong evidence has been found to prove either one.
Studies have placed volunteers on liquid diets that provided plenty of calories and all the essential vitamins and minerals needed, and participants still craved certain foods. This suggests that nutritional deficits are not necessary for cravings of any kind and that these desires are more psychologically based.
Medical texts, however, are filled with fascinating stories about bizarre “food” cravings. Pica is the medical term for a pattern of eating non-nutritive substances (such as dirt, clay, paint chips, etc.) that last for at least one month in the body. The name comes from the Latin word for magpie, a bird known for its large and indiscriminate appetite. Iron deficiency can cause pica and can also cause a craving for ice, referred to as pagophagia. “Tomatophagia” has also been reported in a sixty-six-year-old woman with iron deficiency who consumed several whole tomatoes daily over a two-month period. Her tomato cravings disappeared
when her anemia was treated.
