Tea
The bottom line
A gentle, lower-potassium drink; the National Kidney Foundation suggests up to about 16 ounces when potassium is watched closely.
A healthier swap
No swap needed. Herbal teas vary — some blends are high in potassium or interact with medicines; transplant patients should check with their pharmacist.
Understand the nutrients
Frequently asked questions
Can tea block iron absorption?
Yes — tea (and coffee) drunk with meals reduces iron absorption from plant foods. If anaemia is being treated, take tea between meals instead.
These pages are general education about eating with kidney disease, dialysis or a kidney transplant. They are not medical advice and do not replace your own care plan. Kidney diets are individual: what is right for you depends on your stage, your blood tests, your medicines and your other conditions. Always talk to your care team or renal dietitian before changing what you eat, and never stop or change a medicine because of something you read here.
