While a healthy eating plan is crucial for health, bending the rules on occasion probably won't hurt most people. One strategy to try is the 90-10 rule-eating healthy foods 90% of the time and splurging on unhealthy foods 10% of the time. For example, if someone eats three meals a day for a week, for a total of 21 meals, the person would be able to splurge on 10% (about two) of the meals. Dietitians warn that applying the 90-10 rule to every meal can lead to trouble, such as weight gain.

Sodium is hidden in many everyday foods, including bread, sauces, condiments, cereal, rice, pasta, and processed items such as canned soups, deli meats, and frozen meals.
