Why Is It Bad to Reuse Oil For Cooking?
Reusing oil can cause inflammation and thus cause diseases. Free radicals attach themselves to the healthy cells which turn them into unhealthy cells and results in health problems. Reusing Oil can be root cause of obesity, heart disease and diabetes. Senior Executive Nutritionist Ms. Divya R., Cloudnine Group of Hospitals, Jayanagar, Bangalore shares her knowledge about effects of cooking oil and related health hazards.

Effects of Reused Cooking Oil
When the oil is subjected to high temperature, it undergoes degradation leading to free radical release. Reheating the same oil repeatedly leads to the formation of Total polar compound [TPC] which makes the oil unfit to consume. The toxicity of these polar compounds is associated with many diseases like heart ailments, obesity, cancer, hypertension, liver disorders, Diabetes etc. Also due to repeated reheating, oil loses its nutritional and chemical properties leading to damage in cellular and molecular level.
Many studies have suggested that reheating oil imparts harmful toxins, increases trans-fat and free radical levels in the oil.
A general survey suggests that up to 48% of people consume fried and junk foods weekly 1-6 times, which is really alarming.
FSSAI [Food safety and standard authority of India] has fixed a permissible limit of 25% for the TPC in cooking oil, beyond which it is not safe to consume. Also FSSAI has advised Indian Bio-diesel Association to create a nationwide ecosystem to covert used cooking oil to bio-diesel.
