Good and bad cooking oils
17th July, 2017
You have many options when it comes to choosing your oil for cooking, which can become more confusing and frustrating.
There are two types of fatty acids - saturated and unsaturated. The different types of fatty acids are structurally different and as we would expect, they have different functions in the body.
Saturated fats have a single bond and are found in animal products and dairy. These types of fats are solid at room temperature.
Unsaturated fats are divided into two groups known as Polyunsaturated and Monounsaturated. Polyunsaturated and monounsaturated fats, are found primarily in fish, plant oils, seeds and nuts. These “healthy” fats have been shown to maintain healthy blood cholesterol levels. Even though these fats are better for you than saturated and trans fats, they are still fats, and intake should be moderate to maintain the best of health.
When cooking on a high heat or deep frying, you would want to use fats that are stable and that don’t oxidise or become rancid. When fats go through oxidation, they react with oxygen to form free radicals and become harmful to use.
Anytime you cook food, you run the risk of creating heat-induced damage. The oils you choose to cook with must be stable enough to resist chemical changes when heated on high temperatures, or you run the risk of damaging your health. One of the ways vegetable oils can cause damage is by converting your good cholesterol into bad cholesterol when they oxidise.
Cooking oils to include in your diet
Olive oil: Olive oil can do so much more when it comes to your health. Olive oil is one of the best and healthiest fats, which is pressed from the fruit of the olive.

Extra virgin olive oil is best used in salad dressings and dips. Olive oil has a low smoke point that is the temperature at which it starts to burn and breaks down causing changes in its molecular structure. It is best to add olive oil towards the end of cooking.
Ensure that you keep your olive oil in a dry, cool, dark place to prevent it from going rancid.
Ghee: Ghee is the most preferred cooking oil in India, due to its high smoke point which makes it suitable for cooking. Ghee is rich in CLA (conjugated linoleic acid) the Essential fatty acid found in grass-fed animals.
Casein and lactose have been removed from ghee, these are the substances that are found in dairy, which many people are sensitive to. Often, those with dairy sensitivities can tolerate ghee.
Palm oil: Palm oil is made from palm fruit, which is a great healthy option for high heat cooking and is native to South East Asia. There has been a lot of controversy surrounding palm oil because many palm oil plantations have contributed to the destruction of rainforests. However, it is important to know your source.
Avocado oil: This is one of the best cooking oils because it has such a high smoke point. However, it contains a reasonable amount of polyunsaturated fats which in excess, have been known to cause inflammation.

Canola oil: Is widely recognised as the healthiest salad and cooking oil, which is available to consumers, even though canola oil contains Omega 3s. These oils are fragile and exposed to oxidation through heating. Canola oil also contain uric acid, which can be toxic if consumed in large amounts.
Grape seed oil: Has a moderate high smoke point and contains lots of vitamin E, about twice as much as olive oil. It has the highest concentration of Omega 6 and over 70% polyunsaturated fats (PUFA). As we know, these fats can cause inflammation and can have an absolutely devastating effects on the body’s metabolism.
Oils can be used at the end of cooking to enhance the flavour. Remember to also keep your consumption of all fats to a minimum.
