Think of your kidneys like filters that rid your body of all the things you don't want. These two fist-sized, bean-shaped organs filter your blood. In doing so, they remove toxins and excess fluids while keeping your levels of potassium, sodium and more in check. At the same time, they produce hormones that help to regulate everything from your blood pressure to your bone strength. Long story short: Your kidneys do a lot.

So much, in fact, that they can get overtaxed. Roughly one in seven Americans has chronic kidney disease, which can cause waste and fluid buildup in your body. Worse yet, most people with CKD don't know they have it.

Poor eating habits heighten your risk for CKD. But when you eat the best foods for your kidneys, the reverse can be true. Since certain foods are good for kidneys, what you eat can help to protect your kidney health.

Best foods for healthy kidneys

These are our top picks for foods to add to your diet for optimal kidney health.

1. Fatty fish - Fish delivers protein, and when you choose a fatty fish like tuna, salmon or trout, you're also getting omega-3 fatty acids. According to the National Kidney Foundation, omega-3 fats may help reduce fat levels (triglycerides) in the blood and may also lower blood pressure.

2 Cabbage - This nutrient-dense vegetable is low in both potassium and sodium while packing in fiber, vitamins C and K and more. Plus, cabbage is versatile. You can use it in salads and slaws, but you can also use it as a wrap for tacos, sandwiches and more.

3 Bell peppers - Like cabbage, bell peppers pack in lots of good nutrients with low levels of potassium. With them, you get vitamins B6, B9, C and K, plus fiber. And they deliver antioxidants, too. You can slice them and eat them with dips or roast them up and add them to dinner.
