Healthy Cooking Oils {Health}

[Source:advocuae.com]
Oils are not entirely bad and you can not cut down on oils completely. So, it is essential to be aware of the healthiest oils which are safe to use and do good to your bodies. 

Refined Vegetable Oil
These oils are available under various brand names and are supposed to be extremely healthy and cholesterol controlling and many other benefits. But, in a nutshell, all these oils are processed in industrial conditions under high heat and pressure and refined to a lot of extent. Now, I have said again and again that cold processed oils are the best otherwise they lose their nutrients. And, in the industrial environment, the oils undergo a process called hydrogenation. 

In this process, hydrogen molecules are added to the unsaturated fatty acids of the oils to convert them to saturated fatty acids. While the oils with saturated fatty acids are healthiest and stablest of the cooking oils, in practice this process of hydrogenation is not taken to its completion. Because of this, the oils are partially hydrogenated. Partially Hydrogenated oils have molecules which are inflammatory in nature and are main reasons for diseases of heart and cause burning sensation in the body. 

What is termed as a 'Healthy Cooking Oil'? 
So, now the question is what is healthy? As I said above, saturated fat oils are healthiest as they are stable and generally have a high smoke point. You do not want to have an oil which burns and turns to smoke very soon because frying brings the oil to a very high temperature. And, if the oil reaches its smoke point, the oil loses its nutrients and its chemical bonds undergo changes on its own because of which oil may become entirely unhealthy. 

Now, coconut oil has the highest amount of unsaturated fats which is why it is an extremely healthy cooking oil. But, excess consumption of coconut oil in a day leads to high calories in the body. But, coconut oil has a high smoke point because of which it is a good oil. Similarly, safflower oil, pure ghee (made at home and not from animal fat), groundnut oil, mustard oil, rice bran oil and sesame oil are healthy cooking oils. 

Olive Oil
If you love olive oil to the core, you must be infuriated that how come it has not made it to the list? Well, actually, it does. But, there are certain points regarding olive oil which I wanted to clarify. It is an monounsaturated oil. 

Now, I have seen it often and have personally also probably recommended that Extra Virgin Olive Oil (EVOO) should be used. But, that is not true. EVOO is actually very delicate oil whose, if subjected to high heat, chemical structure changes rendering the oil useless and unhealthy. So, use EVOO only for salads and cooking at low temperatures. Virgin Olive Oil should be used for cooking at high heat as it is more heat resistant but it is little less nutrient when compared to EVOO. And, Pomace is the grade of olive oil which is actually suitable for Indian Cooking as it's structure doesn't get altered with high temperatures.

Which oil do you use? I personally like Sesame and Mustard oil.

Essential Oils and Plant Oils {Beauty Products}

Well, reading one of my reader's comments, I came to know that probably not all are really aware of the difference in the plant oils and essential oils. So, I shall try to clarify that a bit. 

Plant Oils
Body Oils are made of blending 2 or more plant oils
All oils under this category come as vegetable oils. They can be used for culinary purposes or even for skin care. These oils are generally extracted from the fruits like almond nuts, hazelnut nuts, coconut fruit, etc. Some of the oils are extracted from the waste part like the rice bran oil comes from the rice bran which is generally used as a fodder for cattle. These oils can be used directly for any purpose and there is a danger of these oils going rancid over a period of time. 

They are extracted by cold process or a heat processing method. Cold pressed oils are best as the nutrition is intact and the oil goes through the least amount of processing.

Essential Oils
Essential Oils
Essential Oils are extremely concentrated essences of the various parts of a plant. For example, Essential Oil can be extracted from roots, leaves, barks, stems, flowers of a plant. The oil is extremely concentrated and can not be used directly on the skin or hair. Not all essential oils can be used for culinary purposes. To use these oils, one needs to dilute them with the carrier oils (which are the plant oils).

Essential Oils are extracted using the steam distillation or solvent extraction. Steam Distillation gives the best quality of the Essential Oil. To produce an ounce of Essential oil, huge amount of the plant might be needed and that makes these oils extremely costly. For example, a pound of Jasmine flowers give 1 ounce of Jasmine Essential Oil. So, cost is determining factor of the purity of the Essential Oil. One more thing which characterizes essential oils is its strong fragrance which is generally missing in plant oils.
These oils are extremely delicate and come in very small quantities of 10ml or 50ml and mostly, you will find them in dark-colored bottles. The reason why they are put in dark colored is that the composition of the essential oil may be altered by the sun's rays so it is always advised to store these oils in the dark. That preserves their stability. Generally, these oils have long shelf life and can be used as preservatives also in homemade cosmetics.
