Olive Oil: 5 Best Reasons to Include It — and Which Type Is Best

Olive oil is a cornerstone of the Mediterranean eating pattern. The biggest benefits show up when it replaces less‑healthy fats (like butter, shortening, and many highly processed seed‑oil blends) and when you choose high‑quality extra virgin olive oil for most uses.

\n Best overall: Extra Virgin Olive Oil (EVOO)\n Typical amount: 1–2 Tbsp/day\n Use raw + low/medium heat for max polyphenols\n

5 best reasons to have olive oil in your diet

\n\n

\n 1) Better heart and blood‑vessel health\n

Extra virgin olive oil is rich in monounsaturated fat (especially oleic acid) and polyphenols. In Mediterranean‑style diets, it’s linked with fewer major cardiovascular events and improved vascular function.

\n\n

\n 2) Anti‑inflammatory + antioxidant support\n

EVOO contains bioactive polyphenols (like hydroxytyrosol) and compounds such as oleocanthal that have anti‑inflammatory effects. This can help reduce oxidative stress and inflammatory signaling when used regularly.

\n\n

\n 3) Improved metabolic health (blood sugar + insulin sensitivity)\n

Replacing refined carbs or saturated fats with olive‑oil‑based meals is associated with better post‑meal glucose control and improved insulin sensitivity—especially within the full Mediterranean dietary pattern.

\n\n

\n 4) Brain and cognitive support\n

Higher adherence to Mediterranean patterns that include EVOO is associated with better cognitive aging in observational studies and some interventional research. Benefits likely involve anti‑inflammatory and vascular mechanisms.

\n\n

\n 5) Satiety and weight‑friendly fat replacement\n

Fats increase satiety. Using olive oil to replace ultra‑processed fats can improve meal satisfaction and diet quality—helping people stick with healthier eating patterns long‑term (while still respecting total calories).

\n\n

Key point: Olive oil is not “magic.” The strongest benefits are seen when it becomes the main added fat instead of less‑healthy fats, within an overall whole‑food diet.

How to get the most benefit

Use it as a replacement: swap for butter, margarine/shortening, and creamy dressings.
Go raw often: drizzle on vegetables, soups, beans, fish, and whole grains for maximal polyphenol retention.
Cook smart: EVOO works well for low‑to‑medium heat. For very high heat (or long deep‑fry sessions), consider refined olive oil.
Mind portions: healthy fat still has calories—1 tablespoon is ~120 calories.

Simple daily habit: 1–2 tablespoons of EVOO per day (in food) is a common Mediterranean‑style target for many adults.

Shopping checklist (quick and practical)

Look for “Extra Virgin” on the front label.
Find a harvest date (ideally within the last 12–18 months). If there’s only a “best by” date, quality is harder to judge.
Choose dark glass or metal (light degrades quality).
Buy smaller bottles if you don’t use it quickly—freshness matters.
Consider certifications (regional PDO/PGI, California Olive Oil Council, etc.) when available.

Storage

Keep it tightly closed, away from heat/light. Most bottles taste best within ~3–6 months after opening.
