The science of nutrition and healthy eating

Introduction

Welcome to Week 5 of the course.

This week you will get a better understanding of the energy from food and how sweeteners are used in our food and drink.

By the end of this week’s study you will understand:

  • the difference between calories and joules
  • how each food group contributes to the energy in your food and drink
  • how to work out the energy in food
  • the reference values of the different food groups.
