Mediterranean Diet Pattern

Reviewed by the Nimbera editorial team · Last updated May 2026

Galvano et al. (2023) dose-response meta-analysis of 31 RCTs and prospective cohorts (n=17,153) published in Advances in Nutrition found that the highest adherence to a Mediterranean diet was associated with a significant reduction in CRP (weighted mean difference -0.41 mg/L), IL-6, and TNF-alpha compared to control diets (PMID 36774045).$50-100/month food budget increase over a typical Western diet

How to use

Base meals around vegetables, legumes, whole grains, olive oil, nuts, seeds, and oily fish (salmon, sardines, mackerel) 2-3 times per week. Limit red meat to 1-2 times per week and processed foods, refined grains, and added sugars as much as possible. Use extra-virgin olive oil as your primary cooking and dressing fat at 2-4 tablespoons per day. Aim to follow this pattern for at least 12 weeks - inflammatory marker improvements become measurable around this timeframe.

How it works

The pattern delivers high amounts of oleocanthal (olive oil), omega-3 fatty acids (fish), polyphenols (vegetables, legumes), and fiber (whole grains) - all of which act synergistically to suppress NF-kB activation, reduce arachidonic acid metabolism, and shift the gut microbiome toward producing short-chain fatty acids that dampen systemic immune activation.

Where to buy

No supplement required. Extra-virgin olive oil, tinned sardines/mackerel, legumes, and mixed nuts are the highest-impact items to add; most are available at standard grocery stores.

Typical cost: $50-100/month food budget increase over a typical Western diet

Safety notes

The diet is very safe for most adults. If you have a nut allergy, substitute seeds (pumpkin, sunflower, hemp). The original Mediterranean diet includes moderate wine; people with alcohol use disorder, liver disease, or certain medications (metronidazole, tinidazole) should omit alcohol entirely. Fish twice weekly is not appropriate during pregnancy for high-mercury species - choose low-mercury options (sardines, salmon, trout).
