Eating too much salt:

Americans eat on average about 3,400 mg of sodium per day. However, the Dietary Guidelines for Americans recommends adults limit sodium intake to less than 2,300 mg per day—that’s equal to about 1 teaspoon of table salt! For children under age 14, recommended limits are even lower.
