For example, partially hydrogenated oils, often used for their stability and cost-effectiveness, are a significant source of trans fats.
2.3. Acrylamide Formation
When starchy foods like potatoes are deep fried at high temperatures, a chemical reaction can occur that leads to the formation of acrylamide. Acrylamide is a known carcinogen, and while the levels found in food are generally low, regular consumption of foods high in acrylamide may increase cancer risk.
2.4. Advanced Glycation End Products (AGEs)
Deep frying at high temperatures can also lead to the formation of Advanced Glycation End Products (AGEs). AGEs are harmful compounds that form when proteins or fats combine with sugars in the bloodstream. High levels of AGEs have been linked to inflammation, oxidative stress, and an increased risk of chronic diseases such as diabetes and heart disease.
2.5. Oxidation of Oils
During deep frying, oils are exposed to high temperatures and oxygen, leading to oxidation. This process can create harmful byproducts such as aldehydes and lipid peroxides. These oxidized compounds can contribute to inflammation and cell damage in the body.
2.6. Loss of Nutrients
The high heat of deep frying can destroy some of the vitamins and antioxidants present in the food. For example, heat-sensitive vitamins like Vitamin C and folate can be significantly reduced during the frying process. This means that deep fried foods often provide less nutritional value compared to their non-fried counterparts.
