Flash Point vs Smoke Point: What’s the Difference

Flash point is a fire-safety measurement. It refers to the temperature at which oil vapors may ignite if exposed to flame. It has nothing to do with nutrition.

The smoke point is the temperature where oil begins to visibly smoke and chemically break down. Once this happens, the oil produces free radicals and toxic byproducts that damage food quality and stress the body.

Why Smoke Point Matters More As We Age

Seniors are more sensitive to inflammation, oxidative stress, and metabolic dysfunction. Cooking with oils beyond their smoke point adds unnecessary inflammatory load and undermines heart and brain health.

Choosing Oils Using Common Sense Nutrition

High-heat cooking requires stable oils. Low-heat or cold use allows nutrient-rich oils. This simple matching strategy has been used for generations and still works today.

Refined Oils: Higher Heat, Fewer Nutrients

Refining raises smoke point but strips antioxidants. Higher heat tolerance does not automatically equal healthier.

The Bottom Line

Flash point prevents fires. Smoke point and stability protect health. Cook at reasonable temperatures and choose oils that match the job.
