Lemon

A popular treatment for morning sickness, lemons, any way you take them, are great little nausea-blockers. Eat them in foods, suck on them, or just grab and sniff a cut up lemon wedge when the tummy goes for a spinning tea-cup ride.  Also helpful: sucking on sour lemon candies. Why lemon? According to the National Cancer Institute, lemon, lime, and other tart-flavored foods are easy on the stomach.
