Why do women crave chocolate during their periods?
There have been suggestions that chocolate cravings are related to a deficiency of magnesium or are linked to carbohydrate consumption to self-medicate depression, but no strong evidence has been found. Nutritional deficits are not necessary for cravings to occur. These desires appear to stem more from a psychological need.
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 (dirt, clay, paint chips, and the like) that lasts for at least 1 month. 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.
