Many households use refined oil daily for cooking, but very few know how dangerous it can be for long-term health. Refined oils go through multiple industrial chemical processes that destroy essential nutrients and create harmful compounds. Regular consumption leads to serious health issues, especially related to the heart, cholesterol, digestion, and immunity.

Refined oil increases LDL cholesterol and reduces HDL cholesterol. This imbalance leads to fat deposits in arteries, high blood pressure, risk of heart attack or stroke, and poor cardiovascular functioning. Doctors strongly advise replacing refined oil with natural oils for daily use.
