Paget's disease of bone is a chronic condition characterized by abnormal and excessive bone remodeling, leading to weaker, misshapen bones. It is often managed with medication, typically bisphosphonates, to control the excessive bone breakdown. For people with this condition, nutrition plays a crucial supportive role, focusing on providing the building blocks for healthy bone and avoiding any dietary pitfalls that could interfere with treatment. While there is no 'special' diet, emphasizing certain nutrients is key to a robust management plan.
The Foundation of Bone Health: Calcium and Vitamin D
Calcium and vitamin D are the cornerstone of a diet that supports bone health in individuals with Paget's disease. These two nutrients work in tandem: calcium is the primary mineral component of bone tissue, while vitamin D is essential for the body to absorb and properly utilize calcium. Without sufficient amounts of both, bone-building processes can be compromised, exacerbating the issues caused by the disease's chaotic bone turnover.
Calcium Needs and Sources
Adults generally require a daily calcium intake of 1,000 to 1,200 milligrams, with specific recommendations varying slightly by age and gender. This is particularly important for postmenopausal women and older men, who are at increased risk for bone disorders.
Good sources of calcium include:
- Dairy Products: Milk, cheese, and yogurt are excellent sources. Low-fat varieties are often recommended.
- Leafy Green Vegetables: Broccoli, cabbage, kale, and turnip greens are high in calcium. Note that spinach contains oxalates that can inhibit calcium absorption.
- Fortified Foods: Many plant-based milks (like almond, soy, and rice milk), cereals, and some orange juices are fortified with calcium. Shaking cartons of fortified liquids is important, as the calcium can settle.
- Fish with Edible Bones: Canned sardines and salmon are great sources because they include the soft, edible bones.
- Legumes and Nuts: Soybeans, tofu, and almonds also contribute to calcium intake.
Vitamin D Needs and Sources
Vitamin D is often called the "sunshine vitamin" because the body produces it when the skin is exposed to sunlight. However, especially during colder months or for those with limited sun exposure, dietary sources and supplements are crucial. Daily recommendations typically range from 400 to 800 IU, increasing for older adults. Patients with Paget's disease often have a higher prevalence of vitamin D deficiency, making supplementation a common and important part of management.
Sources of vitamin D include:
- Sunlight: Short, daily periods of sun exposure can help your body produce vitamin D.
- Oily Fish: Salmon, mackerel, and sardines are rich in vitamin D.
- Fortified Foods: Cereals, milk, and plant-based milks are often fortified.
- Egg Yolks: A good natural source.
Navigating Medications with Your Diet
For those on bisphosphonate medication, the timing of food and supplements is critical to ensure the drug is absorbed properly and works effectively.
- Take on an empty stomach: Bisphosphonate tablets should be taken with plain water on an empty stomach to maximize absorption.
- Avoid food for at least 30 minutes: Eating food too soon after taking the medication can reduce its effectiveness.
- Space out calcium: Do not take a calcium supplement within two hours of taking a bisphosphonate, as calcium can interfere with drug absorption. Your doctor or pharmacist can help you create a schedule.
Potential Complications and Considerations
While following a bone-healthy diet is generally safe, those with Paget's disease should be aware of potential complications and discuss them with a healthcare provider.
- Hypercalcemia: Excessive breakdown of bone can, in rare cases, lead to high calcium levels in the blood, especially during periods of immobilization. Any symptoms of weakness, fatigue, or abdominal pain should be reported to a doctor.
- Kidney Stones: Individuals with a history of kidney stones should consult their doctor before taking calcium supplements, as they may need to adjust their dosage.
- Excessive Vitamin A: Some research suggests very high intake of vitamin A, particularly from supplements containing retinol or liver, may be linked to an increased fracture risk. It is wise to limit intake and discuss supplements with a doctor.
A Comparison of Bone-Building Nutrients
| Food Category | Calcium Content (Examples) | Vitamin D Content (Examples) | Notes |
|---|---|---|---|
| Dairy | Milk, yogurt, cheese (high) | Fortified milk, yogurt (medium) | Excellent calcium source. Fortified products can boost vitamin D. |
| Fish | Canned sardines/salmon with bones (high) | Fatty fish like salmon, mackerel (high) | Provides both key nutrients. Choose fish with edible bones for higher calcium. |
| Greens | Broccoli, kale, turnip greens (medium) | Limited | Good calcium source for non-dairy diets, but not a significant vitamin D source. |
| Fortified Foods | Soy/almond milk, cereals (high) | Fortified milk, cereal, OJ (medium) | Useful for those with dietary restrictions or needing a supplement boost. Shake liquids well. |
Beyond Nutrition: Lifestyle for Paget's Disease
Managing Paget's disease effectively involves more than just diet. A holistic approach incorporating lifestyle factors is essential for maintaining mobility, joint health, and overall well-being.
- Maintain a Healthy Weight: Excess body weight puts more stress on joints, especially weight-bearing ones like the hips and knees, which can worsen pain and stiffness associated with Paget's-induced arthritis.
- Engage in Regular, Safe Exercise: Physical activity is vital for building strong bones and keeping joints mobile. However, it's important to choose low-impact, muscle-strengthening exercises like walking, swimming, or cycling to avoid putting excessive stress on affected bones. Always consult a doctor before starting a new exercise regimen.
- Limit Smoking and Alcohol: Both smoking and excessive alcohol consumption are detrimental to bone health. For those with Paget's, avoiding these habits is even more critical.
Following a healthy, balanced lifestyle with an emphasis on calcium and vitamin D is a crucial step in managing Paget's disease.

Conclusion
While a special diet for Paget's disease does not exist, a nutrition plan focused on adequate calcium and vitamin D intake is vital for supporting bone health. The timing of supplements relative to bisphosphonate medication is also a critical consideration. By combining a targeted dietary approach with other healthy lifestyle practices like maintaining a healthy weight and engaging in safe, regular exercise, individuals can effectively support their medical treatment and improve their quality of life. Consulting with a healthcare provider is the best way to develop a personalized and safe management strategy.
