The stereotypical foods associated with pregnancy cravings are mostly true
Back in 1978, researchers deemed ice cream, sweets, candy (especially chocolate), dairy, fruits, and fish the most commonly craved items. A few decades later, a study of pregnant adolescents would rank sweets, fruits, fast food, pickles, ice cream, and pizza as the top contenders. Recent surveys have returned similar results -- sugary stuff is always a major player, particularly in the second trimester. In the third trimester, women might start reaching for salty snacks like chips. But chocolate seems to be the kingmaker here. It pops up in just about every study, and has been recorded as the object of pregnant ladies' affections for at least four decades.
