Add a handful of fresh or frozen berries to your morning smoothie, sprinkle them over your cereal or yogurt, or enjoy them as a healthy snack between meals. You can also use berries in baking, such as muffins or pancakes, or create a refreshing berry salad. The versatility of berries makes them easy to include in your diet, regardless of your preferences.

• Pro Tip: Choose organic berries whenever possible to minimize your exposure to pesticides. Frozen berries are also a great option, as they retain their nutritional value and can be more affordable than fresh berries, especially when they're out of season.

Berries are not only beneficial for kidney health but also offer a range of other health benefits.
