16 High Sodium Foods
The recommended daily intake (RDI) for sodium in adults is 2,300 mg/day. For people with chronic kidney disease (CKD), a lower sodium intake of under 2,000 mg/day is recommended—though only your doctor can tell you what's right for you. On average, the daily sodium intake for Americans is about 3,400 mg/day, and you may be consuming much more than you even realize. To help protect your health, it's important to become aware of your salt intake and to focus on choosing low sodium foods, while limiting foods high in sodium.
The effects of too much sodium
Sodium intake can have a big impact on your health, especially if you're living with chronic kidney disease (CKD). Too much sodium contributes to fluid buildup, which can cause high blood pressure and stress on your body. People with kidney disease are already at risk for fluid buildup, known as hypervolemia, because their kidneys aren't working well enough to eliminate excess fluids as efficiently as healthy kidneys would. Eating too much salt can make fluid retention worse.
The good news is that there are several things you can do to help manage your salt and fluids. One big step is learning which high sodium foods to watch out for-and which low sodium foods to choose instead.
