Foods to Avoid After Transplantation
Will I have to watch my diet after a transplant?
Yes, your diet still plays a big role after a kidney transplant. It is important to keep a healthy weight and exercise regularly. A healthy, balanced diet will help prevent high blood pressure, high blood sugar, excess weight gain and promote overall wellness and health.
After a kidney transplant, plan to follow a diet low in salt and high in fiber. A balanced diet includes a variety of fresh fruits and vegetables, lean meats, reduced-fat dairy products, whole grains, and plenty of water. It is important to keep your new kidney hydrated, so drink plenty of water and limit drinks with caffeine.
Additionally, you may need to avoid eating certain types of foods. Your healthcare team can help you understand which foods you should avoid – and why. The dietitian at your transplant center can help you find a diet that is right for you.

Why do I need to avoid certain foods?
After your kidney transplant, you will need to take special medicines, called “immunosuppressive drugs” or “anti-rejection medicines.” These medicines help lower the chances of your new kidney being rejected by your body. However, these medicines also weaken your body’s ability to fight infection. Taking these medicines increases your risk for getting sick from germs, such as bacteria.
Some germs cause bacterial infections. Some bacterial infections can be picked up from food. You can help lower your chances of infection from food by:
- Handling foods safely, like washing your hands often, especially after touching raw chicken or eggs.
- Being careful when eating out.
- Avoiding certain ‘high-risk’ foods because they are more likely to have bacteria that can cause an infection.
You may also need to take steroids, which can cause increased:
- Appetite, causing unwanted weight gain
- Increased blood fat levels (cholesterol & triglycerides)
- Increased blood sugar levels
- Salt and fluid retention (too much fluid in the body)
- It can also cause a breakdown in muscle and bone tissue
Due to unwanted weight gain, it’s important to make healthy food choices and stick to appropriate portion sizes. It may be good to avoid fatty foods and foods high in simple sugar. Check with your doctor before exercise. Most often, exercising 3-4 times a week for 20-30 minutes each time or 5,000 – 10,000 steps every day can help you maintain a healthy weight.
