The Alarming Impact of Refined Oil

Most of us use oil while cooking, as it is essential for enhancing the flavor of dishes. However, there is a particular type of oil that has been linked to numerous fatalities. According to research from the Kerala Ayurvedic University, refined oil is responsible for the deaths of approximately 2 million people annually.

Health Risks Associated with Refined Oil

The consumption of refined oil can lead to severe health issues, including DNA damage, RNA destruction, heart attacks, blockages, brain damage, strokes, diabetes, hypertension, impotence, cancer, weakened bones, joint pain, back pain, kidney damage, liver dysfunction, high cholesterol, reduced eyesight, reproductive disorders, and skin diseases.

How Refined Oil is Processed

The extraction of oil begins with seeds, which are processed with their husks. During this process, impurities are removed, and the oil is refined to eliminate its taste, odor, and color. This involves washing the oil with water, salt, caustic soda, sulfur, potassium, acids, and other hazardous substances to remove impurities. This process generates a thick waste similar to tar, which is often repurposed for tire manufacturing. The use of acids in refining can turn the oil toxic.
