Consulting a dietitian that specialises in the condition (renal dietitian) is an important step if you're living with kidney disease so that they can develop a personalised meal plan.
The renal dietitian will likely complete a dietary assessment to make sure that you're getting all the nutrients you need. That might include things like protein, salt, sugar, potassium, phosphate, fluid and fat. If your diet needs to be adjusted, they'll work with you on your food likes and dislikes to tailor a dietary plan just for you that takes your age, lifestyle, weight, etc. into consideration.
