About the The Science of Food and Nutrition Course

The Science of Food and Nutrition is a practical Health & Wellness course that explains how food affects energy, digestion, performance, disease risk, and everyday wellbeing. You will understand how food works in the body, from molecules and metabolism to practical dietary decisions, so you can make nutrition choices with greater confidence and less confusion.

Build Evidence-Based Nutrition Skills For Better Health & Wellness

  • Learn how carbohydrates, fats, proteins, vitamins, minerals, and water support the human body.
  • Connect digestion, absorption, metabolism, appetite, and energy balance to real food choices.
  • Evaluate nutrition research, media claims, popular diets, supplements, and food labels more critically.
  • Create a personal nutrition framework that supports health, performance, culture, budget, and sustainability.

This course gives you a science-based foundation in food, nutrition, and Health & Wellness decision-making.

The Science of Food and Nutrition begins with the chemistry of food, showing how nutrients provide energy, structure, repair, hydration, and essential biological support. You will study carbohydrates, fats, proteins, amino acids, vitamins, minerals, and water in a clear, practical way that connects scientific concepts to everyday meals.

As the course progresses, you will understand how food works in the body, from molecules and metabolism to practical dietary decisions. Lessons cover digestion and absorption, calories and hormones, appetite and satiety, food choice, physical performance, gut health, the microbiome, and nutrition across different life stages.

You will also build critical thinking skills for navigating modern nutrition information. By examining food labels, dietary guidelines, processed foods, additives, public health concerns, chronic disease prevention, popular diets, supplements, and sustainable nutrition, you will learn how to separate evidence from hype.

By the end of this Health & Wellness course, you will be able to interpret nutrition information, assess dietary claims, and apply evidence-based strategies to your own life. You will leave with a clearer, more balanced understanding of food and the confidence to make informed nutrition choices for long-term wellbeing.
