Osteomyelitis, a severe and persistent infection of the bone and bone marrow, can significantly impact a person's quality of life. While medical treatments are essential, dietary modifications, particularly focusing on protein intake, can play a supportive role in managing the condition and its symptoms. This article explores the relationship between diet, protein intake, and osteomyelitis, drawing upon available research and expert recommendations.
Understanding Osteomyelitis
Osteomyelitis often results from contiguous spread from open wounds, though development of infection may result from compromised soft tissue and bone vascularity, systemic compromise of the host and virulent or resistant organisms. While specific foods or supplements cannot cure osteomyelitis, certain dietary approaches can improve symptoms, reduce inflammation, and support overall bone health.
How Diet Can Help Manage Osteomyelitis
A well-planned diet can improve osteomyelitis in several ways:
- Reducing Inflammation: Some foods possess anti-inflammatory properties, which can help alleviate symptoms. Conversely, other foods may exacerbate inflammation.
- Preventing Further Damage: A balanced, nutritious eating plan with fruits, vegetables, and lean protein provides the nutrients needed to prevent further joint damage. Eating enough antioxidants, including vitamins A, C, and E, may also help.
- Maintaining a Moderate Weight: Excess weight puts extra pressure on joints and can increase inflammation. A diet that supports a moderate weight can lessen osteomyelitis symptoms.
- Strengthening Bones, Muscles, and Joints: Specific foods can strengthen the bones, muscles, and joints, and help the body fight inflammation and disease.
Key Foods to Include in Your Diet
People with osteomyelitis can consider adding the following foods to their diet:
- Oily Fish: Oily fish, such as herring, mackerel, salmon, sardines, sprats, trout, and pilchards, are rich in omega-3 fatty acids. These polyunsaturated fats have anti-inflammatory properties.
- Extra-Virgin Olive Oil: Extra-virgin olive oil is a source of healthful fats and may have anti-inflammatory effects.
- Dairy: Dairy products like milk, yogurt, and cheese are rich in calcium and vitamin D, which increase bone strength. Dairy also contains proteins that can help build muscle. Low-fat options are available for weight management.
- Dark Leafy Greens: Dark leafy greens such as spinach, kale, bok choy, Swiss chard, collard greens, Brussels sprouts, and broccoli are rich in vitamins A, C, and K, stress-fighting phytochemicals, and antioxidants. They are also high in calcium. Broccoli also contains a compound called sulforaphane, which researchers believe could slow the progression of osteoarthritis.
- Garlic: Scientists believe that diallyl disulfide, a compound in garlic, may work against enzymes that damage cartilage. A study indicated that a diet rich in garlic and other alliums can help protect against hip osteoarthritis.
- Nuts: Nuts are good for the heart and contain high levels of calcium, magnesium, zinc, vitamin E, and fiber. They also contain alpha-linolenic acid (ALA), which boosts the immune system. Almonds, walnuts, pine nuts, and pistachios are good choices.
- Green Tea: Green tea contains high levels of polyphenols, antioxidants that experts believe may be able to reduce inflammation and slow the rate of cartilage damage.
- Mediterranean Diet: The Mediterranean diet, rich in fruit and vegetables, whole grains, legumes, fish, yogurt, and healthful fats like olive oil and nuts, may help reduce the inflammation that contributes to the symptoms of osteoarthritis.
Foods to Avoid or Limit
When living with osteomyelitis, it is best to avoid or restrict foods that contribute to inflammation:

- Sugar: Processed sugars can prompt the release of cytokines, which act as inflammatory messengers in the body. This includes sugars added to sodas, sweet tea, flavored coffees, and some juice drinks. Reading labels can help monitor sugar intake.
- Saturated Fat: Foods high in saturated fat can cause inflammation in the fat tissue, worsening or speeding up the progression of some types of osteoarthritis, such as knee osteoarthritis. Foods high in saturated fats include fatty meats and meat products, cream, cheese, butter, chocolate, cakes and pastries, and some oils, such as palm oil and coconut oil.
- Refined Carbohydrates: Refined carbohydrates fuel the production of advanced glycation end (AGE) oxidants, which can stimulate inflammation. Examples include white bread, white rice, and potato chips.
Addressing Common Food Myths
Some people believe certain foods worsen osteomyelitis, but scientific evidence does not always support these theories:
- Citrus Fruits: Despite the belief that the acidity of citrus fruits is inflammatory, they have anti-inflammatory benefits and are rich in vitamin C and antioxidants. However, grapefruit juice can interact with some medications, so it is important to check with a doctor before incorporating grapefruit into the diet.
- Dairy: While some claim avoiding dairy can help, milk, cheese, and other dairy products can have anti-inflammatory effects in some people. An elimination diet can help determine whether symptoms improve or worsen with dairy intake.
- Nightshade Vegetables: There is no scientific evidence supporting the claim that nightshade vegetables like tomatoes, eggplants, peppers, and potatoes contribute to arthritis pain. These nutritious vegetables can have many benefits for chronic health conditions.
The Importance of Protein
Protein is a crucial nutrient for overall health, particularly for individuals with osteomyelitis. It plays a vital role in bone health, immune function, and wound healing.
- Bone Health: Protein makes up about 50% of bone volume and ⅓ of bone mass. Optimal protein intake is essential for bone health. Studies show that suboptimal protein intake increases the risk for low bone mineral density and that older adults following higher protein diets tend to have higher bone mineral density and lower fracture risk. Some osteoporosis experts recommend a protein intake between 1.0-1.2 grams per kg (.45-.54 grams per pound) per day.
- Immune Function: Adequate protein intake is necessary for a healthy immune system, which is crucial for fighting infection in osteomyelitis.
- Wound Healing: Protein is essential for tissue repair and wound healing, which is particularly important in cases of osteomyelitis resulting from open wounds or surgical procedures.
Additional Nutrients for Bone Health
In addition to protein, calcium, and vitamin D, several other nutrients are needed to maintain healthy bones:
- Magnesium: Magnesium is needed to maintain bone health, and not getting enough could increase the risk of developing osteoporosis.
- Vitamin K: Vitamin K is necessary for the function of proteins involved in bone formation and maintenance.
- Vitamin C: Vitamin C is an important antioxidant and may help prevent bone breakdown.
- Zinc: Zinc is needed for proper bone growth and maintenance and also promotes bone regeneration.
The minerals potassium, boron, silicon, selenium, iron, and manganese are also needed for bone health.
Dietary Patterns for Osteomyelitis Management
Research suggests that certain dietary patterns can help protect against osteoporosis development and improve bone mineral density and overall health in people living with osteomyelitis.

- Mediterranean Diet: The Mediterranean diet is rich in whole foods like vegetables, fruits, beans, nuts, and fish. Studies show that a Mediterranean-style diet could help protect against fracture and osteoporosis risk and help maintain healthy bone and muscle mass.
- High-Protein Diet: Maintaining sufficient protein intake could also be helpful for people living with osteomyelitis and those who want to support overall bone health.
Dietary Patterns to Avoid
Diets high in ultra-processed foods, added sugar, and excessive salt could harm bone health and increase the risk of bone diseases like osteoporosis. The Western diet, characterized by high intakes of ultra-processed foods, sweetened beverages, fried foods, processed meats, and refined grains, is linked to lower bone mineral density and a higher risk of osteoporosis and fractures.
The Gut Microbiota and Osteomyelitis
Recent research has highlighted the connection between the gut microbiota and osteomyelitis. Studies in mice have shown that a diet rich in fat and cholesterol can protect against inflammatory bone disease by reducing levels of certain bacteria in the gut. Specifically, the outgrowth of Prevotella bacteria in the intestine was associated with osteomyelitis, while a high-fat diet suppressed Prevotella levels and protected against the disease.
Nutritional Status and Chronic Osteomyelitis
Studies have shown a high burden of malnutrition in adult chronic osteomyelitis patients. Factors such as household monthly income, dietary counseling, and loss of appetite were associated with malnutrition. Targeted interventions such as nutritional status assessment and management, and dietary counseling should be key interventions during the course of chronic osteomyelitis treatment and follow-up.
