Using a food label can help you make healthier decisions.
Step One--look at the serving size. Keep in mind that if you eat more than the serving size listed, you will have to multiply it by the number of servings you consume to get the accurate nutrient information.
Sodium is important to limit for those with hypertension/chronic kidney disease. Try to look for items that are less than 6-10% of Daily Value or items that have "no salt added" or "low sodium" claims. Sometimes items that are low sodium replace sodium with potassium chloride-so if you are monitoring potassium in your diet, keep this in mind.
Sodium will always be listed on a nutrition label but phosphorus and potassium are NOT required. Just because phosphorus and potassium are not listed does not mean that food item does not contain them. Take a look at the ingredient list! All ingredients are listed in order by weight , with the item of the most weight listed first. Search for things like potassium chloride or phosphorus additives that contain "PHOS" in its name. Examples include Phosphoric Acid, Sodium Aluminum Phosphate, Polyphosphates, Calcium Phosphate.
Here are some general guidelines-however talk with your personal dietitian to see what foods are best for you.
