Like many packaged foods, frozen dinners can be loaded with sodium. We're talking up to 2,000 milligrams per serving in some cases, which is close the recommended daily intake maximum of 2,300 milligrams. Check out the nutrition label before you pick out your dinner, and don't forget to multiply everything by the number of servings contained in a single package.
Even though you may be buying a low-calorie meal, it could contain a lot of sodium. Lucky for you, there are more and more companies offering low-sodium varieties these days. Look for meals with less than 140 milligrams per serving ideally, and definitely try and stay under 700 milligrams; anything over that is considered high-sodium content.
