Which oil should I use ❓
An oil is a fatty substance that is, usually, fluid at room temperature. It can be made from fruit 🥥 (olive, nuts, hazelnut, almond, coconut), seeds 🥜 (rapeseed, peanut, soy, sunflower, grapes, squash) or germ 🌽 (wheat, corn).
If all edible oils contain 99.9% of lipids, they are different – some being richer in saturated fats, mono-unsaturated fats or poly-unsaturated fats (omega 3 and omega 6).
While saturated fats are to be avoided, unsaturated fats are essential for our health in the right quantities.
👎 Oils with the highest levels of saturated fats are coconut and palm oils.
👍 Poly-unsaturated oils are oils rich in omega-3 and omega-6. Oils rich in omega 3 are linseed, nut, rapeseed, soybean. Oils rich in omega 6 are sunflower, soya, sesame.
👍 Oils containing the most mono-unsaturated fats are olive and peanut oils.
Oils are not stable at the same temperatures 🔥: above a certain threshold (called smoke point), they burn, decompose and denature, and release toxic substances 🚭 sometimes carcinogenic.
For example, palm oil burns at 240°C/464°F, extra virgin olive oil at 191°C/376°F, butter at 177°C/351°F, and flaxseed oil at 107°C/225°F.
Moreover, refined oils (which have neutral flavors and limited nutritional benefits), have a higher smoke point than virgin and extra virgin oils.
As a result, it is recommended to use different types according to the usage:
🍳 For frying: oils with a high smoke point capable of enduring higher temperatures and making it possible to obtain crispy foods.
🥗 For salad: extra virgin oils rich in mono-unsaturated and poly-unsaturated fats.
And you, which oil do you prefer ❓
