Food chemistry is the study of the chemical processes and components that make up the food we eat. By studying food chemistry, we can learn how our bodies digest and use nutrients from different foods, and make sure the food is safe and healthy to eat. Foods are made up of molecules, which are tiny particles that make up the food. When we eat food, our bodies break down the molecules in the food so we can use the nutrients in them. Different molecules in food can have different effects on our bodies. By studying food chemistry, scientists can learn how different molecules in food interact with our bodies and how this affects our health.
