Control the sodium (salt) in your diet. Eating too much salt causes the body to keep or retain too much water, causing breathing to be more difficult. In addition to removing the salt shaker from your table:
• Use herbs or no-salt spices to flavor your food.
• Don't add salt to foods when cooking.
• Read food labels and avoid foods with more than 300 mg sodium/serving.
• Before using a salt substitute check with your doctor. Salt substitutes might contain other ingredients that can be just as harmful as salt.
