Suryaa Health Desk: Many households and hotels have a habit of reusing cooking oil after frying, often to save money or prevent waste. Medical experts warn that repeatedly heating and using this oil can have severe negative effects on health. Scientific studies indicate that reheating oil changes its chemical composition, releasing toxic substances that increase the risk of life-threatening diseases.
When cooking oil is repeatedly heated at high temperatures, its nutritional value is destroyed, and free radicals and trans fats are produced. These harmful chemicals can cause bad cholesterol to accumulate in blood vessels, leading to increased blood pressure, heart disease, and a higher risk of heart attacks. Experts also note that this practice can weaken the immune system, making the body more susceptible to various infections.
Consuming reused oil can severely damage the digestive system, leading to issues such as indigestion, gas, acidity, and heartburn. Long-term consumption is linked to potential liver-related diseases. Furthermore, experts express concern that toxic fumes and substances released during the reheating process may promote the growth of cancer-causing cells. This practice may also contribute to premature skin wrinkling and signs of aging.
To maintain health, it is recommended to avoid the habit of reusing cooking oil. It is advised to discard oil used for frying or limit its use to a single instance at low temperatures. Adopting proper dietary habits is considered the most effective way to protect long-term health and prevent various illnesses.
