Cravings

Is a morning without orange juice and coffee unthinkable? Can you eat just one cookie, or do they keep calling from the cupboard until they’re all gone? Do you sometimes feel an overwhelming urge to crunch that only chips, not apples, will satisfy?
For most of us, forgoing favorite foods at certain times is not only unthinkable, it seems beyond our ability. Many wonder if such intense desires, or cravings, are driven by a physiological need. And some people even call foods they strongly desire "addictive."
Clearly, researchers don’t classify them in that way. However, they remain unclear whether a legitimate physiological basis for intense desires for certain foods truly exists, citing difficulty in isolating psychological, social and cultural factors that play a strong role in food choices.
