Food Cravings and Vitamin Deficiencies

6. Iodine

Women who experience irregular or heavy menstrual bleeding might be lacking in iodine, which is vital to metabolism. While iodine deficiencies are rare in the U.S., they are not unheard of. In fact, there is research that suggests it might be more common than we think. If you are craving salty potato chips, your body could be lacking iodine. Seafood and sea vegetables are some of the richest sources of this trace mineral. Try adding cod, shrimp, tuna, and seaweed to your diet.
