Healthiest Cooking Oils, Ranked | What Science Says

For the full breakdown, see our best Cooking Oils for Health guide.

Standing in the cooking-oil aisle feels harder than it should. Every bottle claims to be the one, yet the healthiest cooking oils, ranked by actual evidence, point to a handful of unsaturated options. The American Heart Association and Harvard Health agree: the oils you use daily shape your heart health more than any single trendy superfood. Here’s what the research actually supports, from best to merely okay.

Why Fat Type Beats Smoke Point

Most people shop for oil by smoke point, but that’s not the metric that matters most. The American Heart Association recommends choosing oils with less than 4 grams of saturated fat per tablespoon and zero partially hydrogenated oils, which contain trans fats. That single guideline eliminates coconut oil, palm oil, and butter before you even read a label.

Unsaturated fats—monounsaturated and polyunsaturated—lower LDL cholesterol when they replace saturated fats. Authoritative reviews consistently find olive oil and canola oil beat butter, coconut oil, and palm oil for heart health. The FDA backs this up: credible evidence supports a qualified health claim that oleic acid in edible oils like olive, sunflower, or canola may reduce the risk of coronary heart disease.

Relying on fat composition alone has limits, though. Authoritative sources emphasize that no single oil wins every task. Flavor, cooking method, and heat tolerance all factor in.

The Healthiest Cooking Oils, Ranked

The ranking below reflects the strength of heart-health evidence, not marketing buzz. These are the oils you want in your kitchen most days.

The oils that consistently clear the AHA’s saturated-fat gate all make this list.

Specialty Oils: Where They Fit In

Grapeseed and sesame oil earn mixed reviews. Harvard lists grapeseed among neutral cooking oils, but sesame oil gets flagged as fragile—better for low-heat finishing than frying. Use these oils for flavor, not as your daily workhorse.

Unrefined oils deliver more flavor and antioxidants but degrade faster at high heat. Reserve them for dressings and low-heat cooking, and save neutral refined oils for searing and frying.

Oils To Use Sparingly, Or Skip

Coconut oil, palm oil, and butter fail the AHA’s saturated-fat test. Coconut oil packs over 11 grams of saturated fat per tablespoon—nearly three times the AHA’s 4-gram guideline. The “coconut oil is healthy” narrative never survived contact with the evidence; tropical oils consistently rank below unsaturated alternatives in authoritative reviews.

If you’re looking for the best cooking oils for health, the shortlist is the eight oils in the table above—not the tropical ones. That’s the takeaway that survives scrutiny.

FAQs

Is olive oil better than canola oil?

Extra virgin olive oil carries the strongest overall heart-health profile, but canola oil is also excellent. Canola has less saturated fat than olive oil and is repeatedly recommended by the American Heart Association. Both beat butter and tropical oils. Choose by flavor and cooking method: olive oil for taste, canola for neutral versatility.

What’s the healthiest oil for frying?

For deep frying, choose oils with high smoke points and low saturated fat—avocado, peanut, or sunflower oil work well. Extra virgin olive oil works for shallow sautéing but degrades at very high temperatures. Avoid coconut and palm oil for frying; their saturated fat content outweighs any heat stability benefit.

Does coconut oil count as healthy?

No, not in the way its marketing suggests. The American Heart Association recommends oils with under 4 grams of saturated fat per tablespoon; coconut oil contains around 11 grams. Authoritative reviews consistently rank unsaturated oils like olive and canola above coconut and other tropical oils for heart health.
