When someone has chronic kidney disease, it means their kidneys aren’t working as well as they should. This makes it important for them to be careful about what they eat and drink.

1. Salt (Sodium): Too much salt can make their body hold onto water and can raise blood pressure, which can be tough on weak kidneys. So, they should eat less salty snacks and foods.

2. Potassium: Potassium is found in bananas, oranges, and potatoes. It’s good for the heart and muscles, but when kidneys aren’t strong, too much potassium can be a problem. So, doctors might tell them to eat less of these foods.

3. Phosphorus: This is in foods like dairy and whole grains. It helps build strong bones, but too much phosphorus can be harmful when someone’s kidneys are sick. They might need to eat less of these foods too.

4. Fluids: Usually, drinking lots of water is good, but if someone’s kidneys are not very strong, too much water can be hard for them to handle. They might need to drink less than usual.
