Explore kidney-friendly superfoods: discover new recipes, enjoy healthy twists on favorites, and make every meal nutritious for your kidney health.

You may have heard that superfoods are super important for people with kidney disease. While the idea of completely managing kidney disease by eating certain foods is appealing – the reality is not quite that simple.

Many people think superfoods are foods that have special, almost magical, qualities. While some foods are certainly more nutritious than others, no food is the magic answer for good health.

Eating a well-balanced diet of nutritious foods — low-sodium foods packed with vitamins and the right minerals — is one of the best things you can do to help stop or slow the progression of kidney disease.

The nutritious foods we are spotlighting in this section were selected because they are super healthy choices, especially for people living with kidney disease. We are eager to introduce you to some foods and recipes that may be new to you. Also, we are excited to share some different ways to prepare some of your old favorites so you can make kidney-healthy food choices for your family and yourself.

When you have kidney disease, a well-balanced diet is your superfood – and can help to make any meal you prepare super!
