Instead of munching on chips, try calming your brain: meditation, yoga, tai chi, and breathing exercises can help when cravings strike. To curb the craving to chew, chomp on carrots, celery, apples or low-sodium, whole-grain crackers. Or try soothing supplements. Passionflower, lemon balm, and chamomile are safe and effective herbs to relieve tension; L-theanine or a B-vitamin complex can curb anxiety. Rarely, a salt craving may indicate a more serious disease, like Addison’s. If it runs in your family, or you have any symptoms, check with your doctor.
