DASH Diet vs Mediterranean Diet
A side-by-side comparison — no verdict on which is "better," just how they differ.
DASH Diet
An NIH-developed eating pattern built specifically to lower blood pressure, using serving-based targets across food groups plus a sodium limit rather than food bans.
View full DASH Diet page →Mediterranean Diet
An eating pattern modeled on traditional Mediterranean-country diets — vegetables, fruit, whole grains, legumes, nuts, and olive oil as the main fat, with fish regularly and red meat/sweets only occasionally. Not a fixed rulebook or weight-loss program.
View full Mediterranean Diet page →Typical Foods
DASH DietVegetables, fruits, whole grains, low-fat/fat-free dairy, lean protein (poultry, fish), nuts/seeds/legumes a few times a week — defined daily serving counts.
Mediterranean DietVegetables, fruit, legumes, whole grains, nuts and seeds, extra-virgin olive oil, fatty fish (sardines, salmon, mackerel), herbs; eggs, poultry, and dairy in moderation.
Foods to Avoid
DASH DietTable salt/high-sodium foods, cured and deli meats, canned soups, red meat, full-fat dairy, sugary drinks, sweets — limited by serving count, not excluded outright.
Mediterranean DietRed and processed meat, butter/margarine, refined grains, sugary drinks, packaged sweets, highly processed snacks — limited, not banned outright.
Eating Pattern
DASH DietNo specific eating window — serving-count structure (6–8 grains, 4–5 vegetables, 4–5 fruits, 2–3 dairy servings/day, etc.) plus a 2,300mg (or 1,500mg) sodium target, based on a 2,000 kcal reference diet.
Mediterranean DietNo specific eating window — a food-quality framework, not a timed or calorie-counted plan.
Primary Goal
DASH DietLower blood pressure.
Mediterranean DietCardiovascular and metabolic health.
Best For
DASH DietPeople with hypertension, prehypertension, or elevated cardiovascular risk who want a produce-and-whole-grain pattern with RCT evidence behind the blood-pressure claim.
Mediterranean DietPeople focused on long-term heart/metabolic health who want a flexible, food-based pattern over strict rules or tracking.
Macro Emphasis
DASH DietNone — no calorie-restriction or macro-ratio mechanism of its own.
Mediterranean DietNone built in — no calorie counting or macro ratio; total calories still determine weight change.
Health Condition Relevance
DASH DietHypertension/prehypertension, cardiovascular risk; secondary cohort evidence for lower kidney stone risk.
Mediterranean DietCardiovascular disease, stroke, type 2 diabetes risk, all-cause mortality (PREDIMED trial and large cohort evidence).
Evidence Strength
DASH DietStrong — an NIH-developed clinical intervention, with controlled feeding trials (original 1997 trial, DASH-Sodium) through large long-term cohorts.
Mediterranean DietStrong — one of the most rigorously studied diets in nutrition science, with decades of randomized-trial and cohort evidence.
Restrictiveness
DASH DietModerate — works through serving-based targets and a sodium ceiling rather than food bans, but hitting the sodium target usually means cooking more from scratch.
Mediterranean DietLow — not a rulebook with hard limits, food-quality guidance rather than exclusions.
Cost / Accessibility
DASH DietFresh produce plus lean protein can raise grocery cost and prep time versus processed staples; dairy servings may not suit anyone lactose-intolerant or vegan without substitution.
Mediterranean DietMay be less practical for tight food budgets or limited access to fresh produce and fish.
