Reusing frying oil: Hidden risks of a common kitchen habit
Frying is one of the most popular methods of preparing dishes, but it also poses significant health challenges. The key question is: can the same oil be used repeatedly? Many people, looking to save money, choose to reuse it, but few are aware of the consequences of this choice.
At first glance, reusing oil may seem harmless—after all, it's just heated fat. Unfortunately, during frying, oil undergoes complex chemical changes that alter its composition and properties. Harmful substances are formed, which can negatively affect our health, especially when the oil has been previously heated to high temperatures.
Why is frying with the same oil multiple times dangerous?
Oil undergoes oxidation during frying, forming toxic compounds such as acrolein or free radicals. These substances can be carcinogenic and lead to serious chronic diseases, such as atherosclerosis or hypertension. The more you use the same oil, the more harmful it becomes, and fried foods absorb these unhealthy compounds.
Additionally, oil that has been heated multiple times changes its properties—it may smoke at a lower temperature, making frying less efficient and less flavorful. Oil soaked with burnt residues can also negatively affect the taste and quality of the food.
How to take care of your health when frying?
The most important thing is to use the appropriate type of fat. Oils with a high smoke point, such as refined canola oil, coconut oil, or lard, are less susceptible to harmful chemical changes. However, if you decide to fry, remember to dispose of the oil after one use. It's also a good idea to use an oven or a grill pan, eliminating the need for deep frying.
Why is it important to pay attention to the quality of the oil?
Choosing the right oil is key to healthy frying. Although cold-pressed oils are healthier in their raw form, they are not suitable for high temperatures. On the other hand, refined oils, though processed, perform better for frying. If you want to take care of your health, follow guidelines that can help minimize the risks associated with using oil in the kitchen.
