Common Questions About Healthy Fats
Find answers to frequently asked questions about oils, fats, and proper nutrition.
The smoke point is the temperature at which an oil begins to smoke and break down chemically. This is important because:
- Oils heated above their smoke point may develop unpleasant flavours and lose nutritional quality.
- Overheating can produce compounds that are not beneficial to consume.
- Different oils have different smoke points, making some better for high-heat cooking and others for finishing dishes.
This is why olive oil (smoke point ~190°C) is ideal for salads and gentle cooking, while avocado oil (smoke point ~271°C) works better for frying or roasting. Our guide includes smoke points for each oil to help you choose appropriately.
