Could a mediterranean diet help ALS patients? new study explores gut health link
NCT ID NCT07178067
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study looked at 44 people with ALS and healthy controls to see how gut bacteria and short-chain fatty acids change over time. Researchers also tested whether a 6-month Mediterranean diet could shift these levels. The goal was to better understand the gut-brain connection in ALS, not to test a treatment.

- Active substance
- Mediterranean diet
- What this could lead to
- If successful, this could point toward dietary strategies to support gut health in ALS patients.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. Results may not lead to direct clinical benefits.

Who is studied
This prospective, single-center study enrolled adults from Romania diagnosed with ALS at Neurology Clinic 1, Mureș County Clinical Emergency Hospital , with an ALS diagnosis within the past 12 months, disease duration under 1 year, El Escorial (1996) criteria-clinically probable or clinically definite ALS. ALS cohort: N=44 at baseline (T0, Aug-Oct 2022); mean age 58.4 ± 12.5 years; 28 men / 16 women. Follow-up: T1 (6 months): N=36 (8 deaths by T1). T2 (12 months): N=30 (6 additional deaths between T1 and T2). Healthy controls: N=40, age- and sex-matched community volunteers without known neurodegenerative or major systemic disease. The patients were recruited through consecutive recruitment at the Neurology Clinic 1, Mureș County Clinical Emergency Hospital (Târgu Mureș, Romania) over a 3-month window (01 Aug-31 Oct 2022).
