Even kidney-friendly foods can be harmful if consumed in excess. Use measuring cups or a food scale to ensure you're consuming appropriate portion sizes of protein, carbohydrates, and fats.

Cook at home
When you cook at home, you have more control over the ingredients you're consuming. Opt for fresh, whole foods whenever possible, and use herbs and spices to add flavor instead of relying on high-sugar or high-sodium sauces and dressings.
Stay hydrated
Staying hydrated is important for kidney health, as it helps to flush out toxins and waste products. Aim to consume at least 8 cups of water per day, and avoid sugary drinks like soda and juice.
