12 Foods That Can Support Healthy Kidneys

Your kidneys work around the clock.

These two small organs filter waste from your blood, help balance fluids and minerals, support blood pressure regulation, and perform several other essential jobs.

Food alone cannot guarantee healthy kidneys, but your overall eating pattern can make a meaningful difference—especially when combined with regular physical activity, healthy blood pressure, and good management of conditions such as diabetes.

Here are 12 nutritious foods that can fit into a kidney-friendly eating pattern for many people.

1. Berries

Blueberries, strawberries, raspberries, and other berries provide fiber and a variety of vitamins and plant compounds.

They can be added to oatmeal, yogurt, smoothies, or eaten on their own.

For many people, berries are an easy way to add fruit without relying on highly processed snacks.

2. Apples

Apples provide fiber and vitamin C while being naturally low in sodium.

Eat them whole rather than relying on sweetened apple products.

An apple with a small amount of unsalted nut butter can also make a satisfying snack.

3. Red Grapes

Grapes contain water, fiber, and naturally occurring plant compounds.

They can be eaten fresh or added to fruit salads.

As with other fruits, portion size can matter for people who need to carefully manage their carbohydrate or potassium intake.
