Why Cooking Oil Choice Matters
Cooking oils provide essential fats that our bodies need for energy, hormone production, and nutrient absorption. However, not all oils are created equal:
- Smoke Point: The temperature at which oil begins to smoke, producing harmful compounds.
- Fat Composition: Oils contain varying amounts of saturated, monounsaturated, and polyunsaturated fats.
- Flavor Profile: Some oils have strong flavors that enhance certain dishes, while others are neutral.
Choosing the right oil ensures better flavor, healthier meals, and safer cooking.
1. Olive Oil
Types: Extra virgin, virgin, light, and pure olive oil

- Light or pure olive oil: higher-heat cooking like stir-frying or roasting
Health Benefits:
- Rich in monounsaturated fats and antioxidants
- Supports heart health and inflammation reduction
- Linked to improved cholesterol levels and reduced cardiovascular risk
Pro Tip: Avoid heating extra virgin olive oil to very high temperatures; it’s best for cold dishes or low-heat cooking.
2. Coconut Oil
Types: Virgin (unrefined) and refined
Best Uses:
- Virgin coconut oil: baking, medium-heat sautéing, adding coconut flavor

Tips for Using Cooking Oils Effectively
