Science & Evolution of Human Nutrition 

Understanding how nutrition evolved alongside humanity helps us make better choices today. This lesson explores the history of food and its role in human survival, showing why there’s no universal “perfect” diet. Instead of relying solely on nutrition science, you’ll learn to consider the "why" and "how" behind what we eat. From energy-packed foods to the protective nature of plants and animals, this journey reveals how food shapes our health and vitality—and empowers you to fuel your body more intentionally.

Our diets have shaped who we are—fueling our evolution, brains, and societies. In this lesson, you’ll explore how early humans balanced protein, fats, and carbohydrates, and how cooking made food more digestible, powering brain growth. You’ll also discover how the shift to agriculture transformed not just our diets but our entire way of life, enabling population growth, professions, and complex social structures. By understanding the evolution of human diets, you’ll gain valuable insights into how food impacts today both our body and mind.

Macronutrients—proteins, fats, and carbohydrates—are the building blocks of nutrition, each playing a crucial role in fueling and maintaining your body. In this lesson, you’ll learn how your body extracts what it needs from food, why some nutrients are essential, and how they impact energy, repair, and overall health. You’ll also discover how balancing omega-3 and omega-6 fats can support inflammation control and well-being. By understanding the science of macronutrients, you can make smarter food choices to nourish your body and mind.

Our modern environment influences how we seek comfort, pleasure, and energy—often at the cost of our health. This lesson explores how dopamine drives our cravings and the role inflammation plays in chronic diseases. You’ll learn how factors like poor sleep, processed foods, and stress impact your immune system and blood sugar regulation. By understanding the balance between body fat, energy production, and hunger, you can break free from unhealthy habits and build a lifestyle that supports both mental and physical well-being.
