Choosing the right cooking oil significantly impacts both your meal's nutritional value and your overall health. Different oils have varying smoke points, fatty acid compositions, and nutritional benefits that make them suitable for specific cooking methods.

When selecting cooking oils, consider these key factors:

1. Smoke point - the temperature at which oil begins to break down and produce harmful compounds
2. Fat composition - ratio of saturated, monounsaturated, and polyunsaturated fats
3. Processing method - refined vs. unrefined
4. Intended cooking use - frying, sautéing, or dressing
