Nutrition plays a huge part in how well our bodies fight off illness, and that link between food and health has never mattered more. What you eat each day can either strengthen your immunity or leave your body struggling to cope, which is why understanding nutrition is such a valuable skill.
This course covers everything from the basics of food and how the body breaks it down, to the vitamins and minerals your immune system relies on to work properly. You’ll learn how a balanced diet supports good health, how to read food labels with confidence, and how nutrition changes across every stage of life, from pregnancy through to older age. You’ll also explore the link between diet and common health conditions like heart disease, diabetes, and cancer.
