You don’t need a green thumb to start growing your own fruits and vegetables. These beginner plants can be grown indoors, year-round.

Why plant-based diets can be great for some people with kidney disease

Plant-based diets can be extremely beneficial for many people with chronic kidney disease (CKD) at any stage and those who are at risk of developing kidney disease. Consuming less meat and more plant-based foods may even help prevent or slow the progression of kidney disease, type 2 diabetes, high blood pressure, and heart disease. 

Learn how to follow a plant-based diet.

Know which fruits and vegetables are okay for you to eat

There are a variety of plants that people with kidney disease can eat. However, it's important to always check with a healthcare professional before changing your diet. Vegetables and fruits have essential nutrients, but many also contain potassium, which some people with kidney disease may need to limit. Your healthcare team and a registered kidney dietitian are the best resources to help you determine which foods you should and should not eat.

  4. Rinse, drain and repeat every 2-3 days until you see sprouts
  5. Move to indirect sunlight and continue rinsing and draining for an additional three days 
  6. Cut the shoots and eat

Sprinkle the sprouts over salads, add them to wraps, throw them in casseroles, or toss them in a stir fry.
