How to practice Mediterranean diet
Build meals around plants, olive oil, and fish; limit added sugars and processed meat. Choose olive oil over butter, nuts over chips, and fish or legumes over red meat. Moderate portions of red wine (optional, ≤1 glass/day) may be fine if not contraindicated. Consistency matters more than purity, partial adherence still delivers benefits. Suitable for nearly everyone and easily adapted to local cuisines.
The evidence behind Mediterranean diet
Dozens of large prospective cohorts and several RCTs (notably PREDIMED) link this diet to lower risk of stroke, cognitive decline, and Alzheimer’s. Mechanistically, monounsaturated fats, omega-3s, and polyphenols improve cerebral blood flow and reduce inflammation. Benefits extend across populations and life stages, though precise macronutrient ratios vary. Minor debate concerns wine and total fat levels.
