Limiting sugar, fat, and/or sodium are popular ways to improve one's diet. However, these all must be consumed in order to stay alive and maintain proper physiological responses, growth, and development. Consuming too little could be equally (or even more) unhealthy than consuming too much.
Here are some ways to eat less salt: Savor each mouthful of food, use other seasonings such as herbs, spices, hot peppers, lemon, vinegar or lime, read food labels and eat healthier snacks that are "unsalted." Your food does not even need salt more than 90% of the time. Taste it first before adding salt.
