Cooking Oils Under Heat: Which Ones Stay Stable and Which Ones Break Down?

Cooking Oils Under Heat: Which Ones Stay Stable and Which Ones Break Down?
Choosing the right cooking oil is not only about flavor. Under heat, oils change: some stay stable and protective, while others break down, oxidize and form unwanted compounds. This guide explains which oils handle heat best, which ones struggle, and how to match your oil to the way you cook. Why Heat Changes Oils in the First Place Cooking oils are mostly made of triglycerides — three fatty acids attached to a glycerol backbone. When you heat them, especially for long periods or to high temperatures, several things start to happen: Fatty acids oxidize (react with oxygen), forming peroxides and then secondary oxidation products. Double bonds break in polyunsaturated fats, which are more fragile than saturated or monounsaturated fats. Volatile compounds form , contributing to flavor but also to smoke and off-odors. Repeated heating accelerates polymerization and the formation of polar compounds and trans fats. Mod...

How Your Fridge Temperature Affects Nutrition, Spoilage and Food Safety

How Your Fridge Temperature Affects Nutrition, Spoilage and Food Safety
Your refrigerator is not just a cold box. It is a food safety device, a nutrition protector and sometimes a hidden risk if the temperature is wrong. A few degrees too warm and harmful bacteria grow faster. Too cold and some foods lose quality or even freeze. Set correctly, your fridge slows spoilage, keeps nutrients longer and protects your family from foodborne illness. Many home fridges are not as cold as people think. In surveys, a large share of households had fridge temperatures above the recommended level. At the same time, people tend to overload shelves, store hot leftovers incorrectly and keep ready-to-eat foods next to raw meat. All of these habits interact with temperature to shape how long food stays safe and nutritious. This guide explains what science says about refrigerator temperature, how it affects microbes and nutrients and what you can do in a normal kitchen to improve safety. You will also find practical tools that help you measure and contr...
