Cooking oil is an essential part of almost every kitchen. It helps us cook food, improves texture and flavor, and provides dietary fat that the body needs. However, choosing the right oil and using it properly can make an important difference to the nutritional quality of our meals.
Deep-fried foods are popular because high-temperature cooking creates a crispy texture and distinctive flavor. But what happens when the same cooking oil is heated again and again?
The phrase "bad cooking oil" can mean several different things. It may refer to poor-quality oil, improperly stored oil, oil that has become rancid, or oil that has been repeatedly heated during frying.
