what do scientists use
Food scientists and technologists use chemistry, biology, and other sciences to study the basic elements of food. They analyze the nutritional content of food, discover new food sources, and research ways to make processed foods safe and healthy.
The tool scientists use to test their theories is called the scientific method. Whether you are studying stars, caterpillars or medicines, this method remains the same. If you have an idea, or a question, you have to be able to prove it and give evidence so that other scientists can check and test your results.
