Understanding Paget's Disease and the Role of Nutrition
Paget's disease of bone is a chronic condition that interferes with the body's normal bone recycling process, known as bone remodeling. In affected areas, bone breakdown and formation are excessive and disorganized. This can lead to bones that are enlarged, structurally weak, and prone to deformities and fractures. While there isn't a specific 'Paget's disease diet' that can cure the condition, proper nutrition plays a vital supportive role, especially for individuals undergoing treatment. The primary goal of dietary management is to ensure the body has the essential building blocks for healthy bone, which are primarily calcium and vitamin D. This is particularly critical for patients treated with bisphosphonates, the main class of drugs used to manage the disease, as these medications work best when the body has sufficient levels of these nutrients.
The Cornerstone Nutrients: Calcium and Vitamin D
Adequate intake of calcium and vitamin D is the most important dietary consideration for anyone with Paget's disease. These two nutrients work together to maintain bone density and strength.
Calcium: The Building Block of Bone
Calcium is a mineral that is essential for building and maintaining strong bones. About 99% of the body's calcium is stored in the skeleton. In Paget's disease, where bone turnover is high, a steady supply of calcium is necessary to support the formation of new, healthier bone tissue. Insufficient calcium can lead to a condition called hypocalcemia (low blood calcium), especially when taking certain medications.
Vitamin D: The Key to Calcium Absorption
Vitamin D is crucial because it helps the body absorb calcium from the gut. Without enough vitamin D, your body cannot effectively use the calcium you consume, no matter how much you get. The body can produce vitamin D from sun exposure, but many people, especially older adults, may not get enough through sunlight alone. Healthcare providers can perform blood tests to check vitamin D levels and recommend supplementation if needed.
Foods to Emphasize in Your Diet
To meet your calcium and vitamin D needs, focus on incorporating a variety of nutrient-dense foods.
Excellent Sources of Calcium:
- Dairy Products: Milk, yogurt, and cheese are among the richest sources of easily absorbable calcium. Opt for low-fat versions to support overall heart health.
- Leafy Green Vegetables: Broccoli, kale, collard greens, and bok choy are great plant-based sources. (Note: Spinach contains calcium, but also oxalates, which can reduce its absorption).
- Fortified Foods: Many foods have calcium added to them. Look for fortified orange juice, plant-based milks (almond, soy, oat), breakfast cereals, and tofu.
- Fish with Edible Bones: Canned sardines and salmon are excellent choices as their soft, edible bones are packed with calcium.
Top Sources of Vitamin D:
- Fatty Fish: Salmon, mackerel, tuna, and herring are some of the best natural sources of vitamin D.
- Fortified Milk and Dairy: Most cow's milk in the U.S. is fortified with vitamin D, as are many yogurts and plant-based milks.
- Beef Liver and Egg Yolks: These foods contain smaller amounts of vitamin D.
- Sunlight: Sensible sun exposure (e.g., 10-15 minutes on the arms and legs a few times a week, without sunscreen) can help your body produce vitamin D. However, this depends on location, skin tone, and time of year.
Foods and Substances to Moderate
While no foods are strictly forbidden, some substances can interfere with calcium absorption or bone health and should be consumed in moderation.
- High-Oxalate Foods: As mentioned, foods high in oxalates like spinach and beet greens can bind to calcium and prevent its absorption. While nutritious, they shouldn't be your only source of calcium.
- Excessive Sodium: A very high-salt diet can increase the amount of calcium the body excretes through urine.
- Excessive Alcohol: Heavy alcohol consumption can interfere with the body's calcium balance and the hormones that regulate bone health.
Diet and Paget's Disease: A Comparison Table
| Foods to Emphasize (Promote Bone Health) | Foods to Moderate (May Interfere with Bone Health) |
|---|---|
| Low-fat milk, yogurt, and cheese | High-sodium processed and packaged foods |
| Fortified cereals and orange juice | Sodas and other sugary beverages |
| Fatty fish like salmon and mackerel | Excessive caffeine and alcohol |
| Leafy greens like kale and broccoli | Foods high in oxalates (e.g., spinach) as a primary calcium source |
| Canned sardines and salmon with bones | Very high-protein diets that may increase calcium excretion |
| Tofu and other soy products |
The Importance of Medical Guidance
It is crucial to work with your healthcare provider before making significant dietary changes or starting supplements. This is especially true for individuals with a history of kidney stones, as calcium supplements might increase their risk. Your doctor can perform blood tests to check your vitamin D and calcium levels and recommend appropriate supplement strategies.

Conclusion: A Supportive Dietary Strategy
In conclusion, while there's no miracle diet to cure Paget's disease, a nutritional strategy focused on achieving adequate daily intake of calcium and vitamin D is a fundamental part of managing the condition. This approach supports bone health, helps prevent complications like fractures, and ensures that medical treatments like bisphosphonates are as effective as possible. By prioritizing dairy, fatty fish, leafy greens, and fortified foods, and by consulting with a healthcare professional, individuals with Paget's disease can take a proactive role in their skeletal health and overall well-being.
