Why should reheating oil repeatedly be avoided in a low-fat diet?
Answer and explanation
Correct answer: Repeated heating can oxidise oil, forming harmful degradation products and lowering fat quality
Repeated heating exposes oil to oxygen and high temperature, promoting oxidation, polymerisation, and other degradation reactions. The resulting compounds can reduce sensory and nutritional quality and may be undesirable for health. Reheating also does not remove the oil’s calories, so it is not a method of reducing fat intake. A low-fat plan should use limited fresh oil and safer cooking methods.
