Based on PubMed | Is it true that eating nuts can make arthritis worse?

Most people with arthritis do not need to avoid nuts and in many cases, nuts can be part of an anti‑inflammatory eating pattern that may help symptoms rather than worsen them. Evidence‑based guidance commonly includes nuts within healthy dietary patterns for inflammatory arthritis, and diets rich in nuts have been associated with favorable inflammation markers and cardiovascular benefits, which are important for many people living with arthritis. ^{[1] [2]}

Quick take

• Nuts are generally not known to trigger arthritis flares and are often recommended as part of anti‑inflammatory or Mediterranean-style eating patterns. ^[2]
• Potential exceptions include a personal food sensitivity, calorie concerns for weight management, or coexisting gout considerations (more below). ^{[3] [4]}

What the evidence suggests

Anti‑inflammatory profile of nuts

• Guidance for inflammatory arthritis often highlights nuts, along with fatty fish and olive oil, as foods that may help ease symptoms as part of an overall healthy diet. ^{[1] [2]}
• Nuts contain unsaturated fats, plant proteins, fiber, vitamin E, minerals, and antioxidant phytochemicals that can support heart and metabolic health and may have anti‑inflammatory effects. ^[5]
• In studies of cardiometabolic health, adding mixed nuts has been linked with improvements in some inflammatory markers (for example, reductions in interleukin‑6 in certain settings), suggesting a trend toward lower systemic inflammation, although results can vary and not every marker (like C‑reactive protein) changes consistently. ^{[6] [7]}

Mediterranean diet data (includes nuts)

• Mediterranean-style diets that include nuts have shown overall anti‑inflammatory effects in high‑risk adults, with reductions seen in circulating inflammatory signals over months of follow‑up. ^[8]
• In large cohorts within Mediterranean diet trials that used extra olive oil or nuts, better adherence was associated with more favorable uric acid profiles over time, which matters because high uric acid can lead to gout. ^[9]

Arthritis types and nuts

Osteoarthritis and inflammatory arthritis

• No high‑quality evidence shows that nuts worsen osteoarthritis or autoimmune arthritis; in fact, healthy patterns that include nuts are often recommended to support weight control and reduce inflammatory burden. ^{[1] [2]}
• Keeping a healthy weight is important because extra body weight increases joint stress; nuts can fit into a calorie‑aware plan as a nutrient‑dense snack or meal component. ^[1]

Gout considerations

• Gout is driven by uric acid buildup from purine metabolism; high‑risk foods include alcohol (especially beer), sugary drinks, red and organ meats, and certain seafood not nuts. ^{[10] [11] [4]}
• Reviews of dietary patterns indicate that nuts and legumes are associated with a lower risk of hyperuricemia and gout, making them generally a good choice for people managing uric acid again, in appropriate portions. ^{[12] [13]}

When might nuts seem to make symptoms worse?

• Personal sensitivity: Some people notice joint symptoms after certain foods; this can occur idiosyncratically. If you suspect a specific nut triggers symptoms, a short, structured trial (limit and re‑introduce while keeping other variables stable) can help you discern cause and effect. (General advice without a required citation)
• Portion size and weight: Nuts are calorie‑dense; overeating can lead to weight gain, which may aggravate joint pain due to increased mechanical stress. Choosing measured portions helps balance benefits and calories. ^[1]
• Salted or sugary nut products: Heavily salted or sugar‑coated nuts are less desirable, as excess salt and added sugars align poorly with heart‑healthy and anti‑inflammatory goals. Choosing unsalted, plainly roasted, or raw options is preferable. ^{[2] [3]}

Practical tips for including nuts

• Portion guidance: Aim for about a small handful (roughly 28–30 g, or 1 ounce) a day as part of your overall calorie plan. (General advice without a required citation)
• Smart swaps: Replace processed snacks or foods high in saturated/trans fats with nuts to improve the overall inflammatory profile of your diet. ^[2]
• Pair with plants: Combine nuts with fruits, vegetables, whole grains, and olive oil within a Mediterranean‑style pattern to maximize benefits for inflammation and cardiovascular health. ^{[2] [8]}
• Variety matters: Walnuts provide alpha‑linolenic acid (a plant omega‑3), while almonds, pistachios, and hazelnuts offer different micronutrients and phytochemicals rotating types can diversify benefits. ^{[3] [5]}

Bottom line

• There is no strong evidence that nuts worsen arthritis; rather, they are often part of recommended eating patterns for inflammatory conditions and joint health. ^{[1] [2]}
• For gout specifically, nuts are not a purine‑dense trigger and are generally considered compatible with gout‑friendly diets, unlike red/organ meats, some seafoods, alcohol, and sugary drinks. ^{[10] [11] [4]}
• Individual responses vary, so if you notice symptoms after certain nuts, consider a structured trial and discuss with your clinician or dietitian, especially if you are managing multiple conditions. (General advice without a required citation)
