In this video, Dr. Neelesh Korde explains why coconut oil is so beneficial for the human body, whether it is consumed internally or used externally. This oil does not raise the cholesterol level as much as other oils do, in fact it does not strain the lipid system of the body. Coconut oil is thin and when applied on the skin, it is absorbed very fast.
Sources of oil are based on geographical location and nature astutely created these oils because humans required the fats for food. Oils are derived from local plant sources. In the coastal regions, there is an abundance of coconuts; in the plateaus, peanuts are found in plenty; in the northern plains, mustard is the chief source for oil. When it comes to naming the best oil, Ayurveda, which normally never generalizes, states that sesame oil is good for everyone, irrespective of their constitution.
Oil has traditionally been extracted from sources such as coconut, sesame and mustard using the technique of cold pressing. Oils extracted in this manner didn't have any toxic material in them since they were unprocessed. Today various other methods are used for deriving oil, rendering them unhealthy.
There are fats from animal sources, one of which is ghee. Dr. Korde goes on to discuss ghee and why it is beneficial. While animal fat is a direct derivative, ghee undergoes the process of heat, this makes it light and it doesn't stick to the walls of the arteries. Geographical location is equally important while choosing oils, for this, along with genetic composition, will determine whether you can digest a particular oil. A person living in the south of India will find it easy to digest coconut oil whereas in the north, people digest mustard oil quite easily.
