Harmful effects of refined oils & marketi gymmics
Health benefits
Mustard oil is derived from mustard seeds which is a little pungent and dark yellow in color. It is widely used as cooking oil in India. It is known to contain healthy fats that do not accumulate in the blood vessels and is also a source of omega 3 and 6 fatty acids and decreases the cholesterol level. Mustard oil has Glucosinolate, an antimicrobial ingredient that provides protection from infections.
Refined oils are natural oils which have been processed to remove impurities, odor, and contaminants. They are chemically treated to make the oil look clearer and cater to the customers' preference. Not many health benefits of refined oil are known apart from the fact that it is rigorously treated to meet the needs of the customers such as refined oils for heart patients. Filtered oil, on the other hand, is made by only eliminating impurities without being chemically processed which is better than refined oil.
Harmful effects
Though generally mustard oil is regarded as healthy, researchers have found its downside too. Mustard oil has considerable amounts of erucic acid and heavy consumption may cause diarrhea or anemia. It is also known to cause skin eruptions and Rhinitis. It is recommended to consume moderate amounts of mustard oil so that you don't expose yourself to such risks.
Refined oils have much more harmful effects on your health than mustard oil. To begin with, the very fact that it is chemically treated makes it quite harmful. The process of refining involves nickel which has detrimental effects on the skin, respiratory system and liver. Preservatives and sodium hydroxide are also added during the processing which is harmful to the digestive system.
It is always better to go natural; so, mustard oil wins the debate but not without some glitches. It is advisable to choose your oil wisely and also monitor your consumption.
