It seems like people always telling you to stay away from sodium, but not all sodium is bad. The body actually needs some salt to continue working properly, but there are healthy versions and not so healthy versions.
Dairy foods like milk and yogurt are excellent sources of potassium and healthy amounts of sodium, but stay away from cheeses. Cheese, especially the processed variety, has a high amount of sodium without the added nutritional benefit of potassium.
Processed meats like canned meats and lunch meats should be avoided due to their high sodium levels. However, foods like chicken, turkey and fish are all healthy meat options.
Fruit is an excellent source of potassium. Try eating melons, bananas or apricots to get a potassium boost in your diet.
Eating your vegetables can increase your potassium intake, but stay away from the canned goods. Canned vegetables have much higher levels of sodium than the fresh or frozen variety.
Unsalted nuts can serve as a quick snack to boost your potassium during a workout, and nut butters, like peanut butter, can be good. However, check the salt content in your peanut butter. Some peanut butters contain more salt than you need.
