In a 2026 randomized trial of 82 adults with rheumatoid arthritis, 12 weeks of DASH eating lowered a standard disease score and pain more than usual eating did. But CRP, a common blood marker of inflammation, did not improve more, and only 49 people finished.https://inflammation.news/articles/does-lack-of-sleep-cause-inflammationhttps://inflammation.news/articles/does-lack-of-sleep-cause-inflammationFri, 30 Oct 2026 00:00:00 +0000One bad night does not seem to raise inflammation markers. But in lab studies, 3 or more short nights in a row raised two of them, IL-6 and CRP. Months of poor sleep are linked to higher levels too. And in trials, treating insomnia or sleep apnea lowered some markers.https://inflammation.news/articles/glp1-drugs-and-inflammationhttps://inflammation.news/articles/glp1-drugs-and-inflammationFri, 30 Oct 2026 00:00:00 +0000GLP-1 drugs lowered CRP in trials, sometimes before weight loss. The heart benefit is solid, but an Alzheimer's trial found no benefit.https://inflammation.news/articles/do-seed-oils-cause-inflammationhttps://inflammation.news/articles/do-seed-oils-cause-inflammationFri, 30 Oct 2026 00:00:00 +0000Seed oils do not appear to cause inflammation. A 2017 meta-analysis of 30 randomized trials found that eating more linoleic acid, the main omega-6 fat in food, did not meaningfully change CRP, IL-6 or TNF-alpha. People with more of that fat in their blood tend to have lower CRP, not higher.https://inflammation.news/articles/fibermaxxing-and-inflammationhttps://inflammation.news/articles/fibermaxxing-and-inflammationFri, 30 Oct 2026 00:00:00 +0000Only a little, and not reliably. A 2022 umbrella review of 52 meta-analyses linked more fiber to lower TNF-alpha but found no clear change in CRP, the best-known inflammation marker. In 14 trials of adults with overweight or obesity, CRP fell just 0.37 mg/L on average. Fiber is still worth eating for heart and blood sugar benefits.https://inflammation.news/articles/home-hs-crp-testshttps://inflammation.news/articles/home-hs-crp-testsFri, 30 Oct 2026 00:00:00 +0000hs-CRP is a real heart-risk marker, but one home reading is noisy: two tests can differ by up to 71%. When testing helps and how to read it.https://inflammation.news/articles/do-cold-plunges-reduce-inflammationhttps://inflammation.news/articles/do-cold-plunges-reduce-inflammationFri, 30 Oct 2026 00:00:00 +0000Mostly, no. A 2026 umbrella review of 15 meta-analyses found no clear effect of cold water on CRP or IL-6, two blood markers of inflammation. A 2025 meta-analysis found inflammation markers rose in the first hour after a plunge. What cold water does well is ease sore muscles after hard exercise.https://inflammation.news/articles/does-exercise-lower-inflammationhttps://inflammation.news/articles/does-exercise-lower-inflammationFri, 30 Oct 2026 00:00:00 +0000Mostly yes, though the proof is weaker than it sounds. A 2026 review of 61 meta-analyses linked regular exercise to lower inflammation markers in most chronic diseases, but rated 219 of 318 results low or very low certainty. Strength training at least 3 times a week has the clearest record in trials.
