A low phosphorus diet can feel like a lot to take in at first, but it doesn’t have to be! This guide will walk you through everything you need to know. We’ll cover why phosphorus is important, which foods are your friends (and which aren’t), and give you tips on making delicious, kidney-friendly meals.
Why Phosphorus Matters
Phosphorus is a mineral found in many foods. It works with calcium to keep bones strong and helps your body make energy. However, too much phosphorus can harm your kidneys if they’re not working properly. When kidneys can’t filter excess phosphorus, it builds up in your blood, leading to weak bones, heart problems, or itchy skin.
Low Phosphorus Foods: What to Eat and Avoid
Eat These:
- Fruits: Fruits are naturally low in phosphorus and packed with vitamins. Apples, berries (strawberries, blueberries), grapes, pineapple, watermelon.
- Vegetables: Cucumber, lettuce, bell peppers, cabbage, zucchini and carrots. Avoid veggies like potatoes or tomatoes unless soaked or cooked to reduce potassium.
- Grains: White rice, pasta, white bread, and corn-based cereals (like Cream of Wheat). Whole grains (e.g., oatmeal, brown rice) have more phosphorus.
- Proteins: Skinless chicken/turkey, egg whites, cod, tilapia, tofu. Limit red meat and avoid processed meats (sausages, bacon).
- Dairy Alternatives: Unsweetened almond milk, rice milk, or small amounts of cream cheese. Avoid: Regular milk, yogurt, and cheese (they’re high in phosphorus).
- Snacks: Unsalted popcorn, pretzels, jelly beans, or homemade fruit sorbet.
Avoid These:
- High-Phosphorus Foods: Milk, cheese, ice cream, yogurt, nuts, beans, whole grains (like oatmeal), processed meats (sausages, deli meats).
- Foods with Additives: Check labels for words like “phosphate,” “phosphoric acid,” or “dicalcium phosphate” (common in soda, packaged snacks, and fast food).

Can a person on a low phosphorus diet eat butter?
Butter is generally considered low in phosphorus and is often allowed on a low phosphorus diet, but portion control is key due to its high-fat content.
Can I eat bagels on a low phosphorus diet?
Bagels can be moderate in phosphorus depending on the ingredients. It’s best to check labels, as some bagels may contain added phosphate additives.
Can you eat mushrooms on a low phosphorus diet?

Why is a low phosphorus diet recommended for hypoparathyroidism?
A low phosphorus diet helps manage hypoparathyroidism because reduced parathyroid hormone (PTH) levels lead to higher serum phosphorus levels; limiting dietary phosphorus prevents complications like calcifications.
How to Lower Phosphorus Quickly?
- Limit high-phosphorus foods like dairy, nuts, seeds, and processed foods.
- Avoid phosphorus additives by choosing fresh, unprocessed foods.
- Take phosphorus binders as prescribed by your doctor to reduce absorption.
- Use calcium carbonate antacids to help block phosphorus intake.
- Increase fluid intake to help kidneys flush out excess phosphorus.
- Switch to low-phosphorus alternatives, such as unsalted butter or plant-based milk.
