Bill Nye the Science Guy S04E02 · Nutrition

Overview

All food, whether it’s protein, fat, carbohydrates, vitamins, or minerals, is made of chemicals. When your body gets a hold of these chemicals, it recombines them and makes energy. Different types of food make different amounts of energy, which are measured in calories. How do scientists figure out the amount of calories in food? In this episode, Bill will reveal the secrets of the bomb calorimeter – an instrument of food science.
