Best Cooking Oils: Coconut or Another Oil

With so many cooking oils on the market today, are any of them actually nutritious? Many oils are fads, even to the point that a contestant on Shark Tank mentioned that coconut oil was a "superfood." According to basic biochemistry, unhealthy oils high in saturated fats solidify at room temperature. Now, imagine eating a saturated fat rich oil. Due to the chemical nature of these oils, they easily pack together and build-up in our bodies leading to chronic diseases. Heart disease is one example. Although the relationship between saturated fats and heart disease may be conflicting in the scientific literature, researchers agree that saturated fats are a risk factor for heart disease.
The key to finding the right cooking oil depends on several factors:
- Amount of Saturated Fats
- Amount of Monounsaturated Fats
- Omega-6 : Omega-3 Ratio
- Smoke Point
It is recommended to consume oils with less saturated fats and more monounsaturated fats. With respect to this, Almond, Apricot Kernel, Avocado, Canola, Hazelnut, Macadamia, Olive, Safflower (high oleic), and Sunflower (high oleic) Oils have ideal amounts of monounsaturated fats.
In regards to polyunsaturated fats, the omega-6 : omega-3 ratio is crucial as well. This ratio in Western diets is 15 : 1 – 16.7 : 1, but the recommended ratio should be between 1 : 1 – 5 : 1. An unbalanced ratio (i.e., excess amounts of omega-6) is associated with heart disease, cancer, and inflammatory and autoimmune diseases. Based on this ratio, Camelina, Canola, Flaxseed, Ghee, Hemp Seed, and Mustard Oils are ideal.
The smoke point is also important, especially for high temperature cooking because low smoke point oils can break-down and lead to the presence of harmful chemicals in food. More refined oils have higher smoke points. For instance, Olive Oil (see infographic below) generally has a low smoke point (this can be harmful when cooking at high temperatures), but refined Olive Oil has a smoke point greater than 204 ℃ / 400 ℉.
Although Flaxseed and Hemp Seed Oil have a low omega-6 : omega-3 ratio, they have low smoke points. That leaves us with Canola Oil for high temperature cooking. Wild Canola Oil naturally has erucic acid, which is toxic at high doses, but breeding techniques have reduced the amount of this fatty acid. While oil content depends on where a plant was cultivated, which variety was grown, and how the oil was extracted, breeding techniques are always improving our cooking oils.
And no, coconut oil is not a "superfood."
