Chemical changes very often happen when you prepare a meal. For example, when cooking a cake, the yeast reacts and the cake rises. Whenever something changes and you cannot reverse that change, it is a chemical change whereas if you can change it back, it is a physical change!
The mitochondria changes food energy to chemical energy.
Examples of chemical changes that occur around us include burning wood (combustion), rusting of iron (oxidation), and cooking food (chemical reactions in the ingredients). Examples of chemical changes that occur within us include digestion of food (enzymatic reactions), respiration (breaking down glucose for energy), and metabolism of medications in our bodies.
Digestion of food involves various chemical changes to break down nutrients. Rusting of iron due to oxidation is a common chemical change. Baking bread involves chemical changes like yeast fermentation and protein denaturation. Combustion of fuel in cars involves chemical reactions to produce energy. Photosynthesis in plants is a complex chemical process that converts light energy into chemical energy.
Energy changes involved in cooking include converting electrical or thermal energy to heat energy to cook food, converting potential energy in food into kinetic energy for cooking processes such as stirring or chopping, and converting heat energy to chemical energy through reactions like caramelization or Maillard browning.
Food undergoes physical, chemical, and biological changes during storage and preparation. Physical changes may include freezing, heating, or grinding. Chemical changes involve oxidation, browning, or fermentation. Biological changes occur when microbes grow and spoil the food.

Using a microwave is a physical change because it involves the application of electromagnetic radiation to heat and cook food. Chemical changes would involve alterations to the molecular structure of the food, which typically does not occur solely due to microwave heating.
It is a chemical change because the heat and whatnot alter the chemical makeup.
The group of nomads were scarce on food. After the nomad found the food for his group, they made a big fire to cook it.
Physical changes are how the food is broken down. For now, it's still food. Chemical changes are when the food is broken down and absorbed. then, what's left is turned into feces. It's not food anymore.
