Course Description

Making confident food choices can feel overwhelming when advice changes every week. This free online nutrition course helps you replace confusion with practical understanding so you can build eating habits that support energy, performance, and healthy weight goals. You will learn how to evaluate common claims, connect what you eat to what your body does with it, and make informed decisions that fit real life rather than short-term rules.

Start with the foundations of a healthy diet and the logic behind dietary recommendations. From there, explore how the body digests and absorbs nutrients and why that process matters for everything from satiety to blood sugar management. You will develop a clear understanding of carbohydrates, lipids, and protein, including how each macronutrient contributes to health, how different types of dietary fat impact heart disease risk, and what makes amino acids unique.

As you move into metabolism and energy balance, you will connect the science to everyday outcomes like body composition and sustainable weight management. You will learn to think in terms of energy density, realistic weight-loss pace, and how nutrition supports physical activity, including which nutrients are used for quick energy when you start moving. The course also strengthens your micronutrient literacy with an approachable look at water-soluble and fat-soluble vitamins, major and trace minerals, hydration, and key roles these nutrients play in the body.

Nutrition needs change across life stages, and this course guides you through considerations for pregnancy, lactation, infancy, adolescence, adulthood, and older age. You will also examine how diet links with disease prevention, basic immune responses, food safety concerns such as the bacterial danger zone, and situations where nutritional support or IV therapy may be required. Throughout the learning experience, short exercises help you check your understanding and turn concepts into usable knowledge, making it easier to apply what you learn to yourself, your family, or your professional growth.
