Understanding the Link Between Diet and PMR Symptoms
Polymyalgia rheumatica (PMR) is characterized by chronic inflammation, and while the exact cause remains unknown, certain dietary choices can either fuel this inflammation or help calm it. An anti-inflammatory diet can be a powerful tool for managing symptoms and improving overall well-being alongside medical treatment. The goal is to reduce the burden of inflammation on your body by avoiding foods that can provoke it. This is particularly important for those taking corticosteroids, as a healthy diet can also help mitigate common side effects like weight gain and elevated blood sugar.
Key Food Groups to Avoid with Polymyalgia Rheumatica
Limiting certain types of foods can help reduce inflammation and support your body's healing process. The following food groups are often recommended for avoidance or significant reduction in a PMR diet.
Highly Processed and Fried Foods
These foods are typically loaded with unhealthy fats, excess sodium, and preservatives, which can increase inflammation in the body.
- Fried Foods: French fries, fried chicken, and other deep-fried items contribute to inflammation. Opt for baked, grilled, or steamed alternatives instead.
- Packaged and Processed Snacks: This includes items like potato chips, cookies, and packaged baked goods that offer little nutritional value and are often high in inflammatory ingredients.
- Fast Food and Frozen Meals: These are often prepared with processed oils and high levels of sodium and sugar.
Added Sugars and Refined Carbohydrates
Excessive sugar intake can lead to advanced glycation end products (AGEs), which promote inflammation. Similarly, refined carbohydrates, which lack fiber and nutrients, can cause rapid spikes in blood sugar that may exacerbate inflammation.
- Sugary Drinks: Sodas, fruit juices with added sugar, and sweetened coffees should be minimized.
- Refined Grains: White bread, white rice, and pastries are refined carbohydrates that are best replaced with whole-grain versions.
- Candy and Desserts: High-sugar treats can contribute to inflammation and weight gain.
Red and Processed Meats
Some research suggests that red meat and, more definitively, processed meats are linked to increased inflammation. These foods are often high in saturated fats and additives.
- Processed Meats: Hot dogs, sausage, bacon, and deli meats should be limited or avoided.
- Red Meat: Burgers and steaks can also contribute to inflammation. Consider replacing them with lean protein sources like fish or chicken.
Unhealthy Fats
Trans fats and high levels of saturated fats are pro-inflammatory.
- Trans Fats: These are often found in margarine, shortening, and some pre-packaged baked goods.
- Processed Vegetable Oils: Some vegetable oils are high in omega-6 fatty acids, which can be inflammatory when consumed in excess.
Excess Sodium and Alcohol
Corticosteroid treatment for PMR can cause fluid retention and increase blood pressure, so limiting salt intake is especially important. Alcohol consumption is also known to increase inflammation and should be restricted.
Comparison Table: Foods to Limit vs. Healthier Alternatives
| Category | Foods to Limit/Avoid | Healthier Alternatives |
|---|---|---|
| Carbohydrates | White bread, white rice, pastries, sugary cereals | Whole-grain bread, brown rice, oats, fresh fruit |
| Fats | Margarine, shortening, processed oils, fried foods | Olive oil, avocado oil, nuts, seeds, fatty fish (salmon, sardines) |
| Protein | Red meat (steak, burgers), processed meats (hot dogs, deli meats) | Lean poultry, fish, beans, lentils, tofu |
| Beverages | Soda, sweetened juices, alcoholic beverages | Water, herbal tea, unsweetened fruit juice |
| Snacks | Potato chips, cookies, high-sugar baked goods | Nuts, seeds, fresh fruits, vegetables, Greek yogurt |
Dietary Support While on Steroid Treatment
If you are on long-term corticosteroids for PMR, your diet plays an additional role in managing side effects. Steroids can increase the risk of osteoporosis and elevated blood sugar. Focus on incorporating foods rich in calcium and vitamin D, and monitoring your intake of added sugars and refined carbohydrates. Rich sources of calcium include leafy greens, fortified cereals, and low-fat dairy or dairy alternatives. Vitamin D can be found in fatty fish, eggs, and fortified products. A balanced diet can help counteract these potential adverse effects.
Should You Avoid Nightshades?
While some anecdotal reports suggest that nightshade vegetables (like tomatoes, peppers, and potatoes) can worsen inflammatory conditions, scientific evidence to support this is lacking. These vegetables are nutrient-dense and offer anti-inflammatory benefits through their high antioxidant content. If you suspect a sensitivity to nightshades, consider an elimination diet under a doctor's supervision to monitor for symptom changes. Otherwise, there is no need to avoid them.

Conclusion: Making Informed Dietary Choices for PMR
Managing Polymyalgia Rheumatica requires a multi-faceted approach, with diet serving as a critical pillar of support alongside medical treatment. By consciously reducing or eliminating pro-inflammatory foods such as processed goods, excess sugar, red meat, and unhealthy fats, you can help soothe your body's inflammatory response. Remember to prioritize a diet rich in whole foods, like those found in a Mediterranean-style eating plan, to support overall health and address the side effects of medications. Always consult with your doctor or a registered dietitian before making significant changes to your diet to ensure it aligns with your specific health needs.
