Refined vegetable oils have dominated the market since last 40 years . Oils and fats have earned a very bad reputation through this time since their consumption is directly correlated with increased risk of heart diseases and cancer.

Refining of oil is a very rigorous process involving use of several machines and chemicals. Refining  is actually responsible for changing the basic composition of oils which then alters the hormonal balance, inflammatory processes and metabolic responses in our body

There are 3 main issues with the conventional oil manufacturing process used today:

Heating: Pulp of the oil seed is heated (230 degree C) under pressure . With such high temperatures, harmful compounds called polycyclic aromatic hydrocarbons are formed, which are known to be cancer causing. High temperatures destroy natural nutrients in the oil seeds such as antioxidants, vitamins and minerals, especially those that are heat sensitive.

Chemicals: A solvent (hexane) is added to the oilseeds so as to dissolve all the solutes in the seeds and maximize output. This solvent is not suitable for humans as its exposure is associated with neural disorders and skin problem.

Preservatives: Preservatives are added to the refined oil which has been ripped off of its natural protective components.  These preservatives prevent the spoilage of oil which was the intended role of antioxidants naturally present in the oil seeds.

Oils that have been refined through this process stay longer on the shelves and are more stable. This, however, is at the cost of its nutritional value.

Once again, we are compelled to embrace MAN MADE over factory made food.
