Carbohydrates are often blamed for chronic diseases such as diabetes, heart disease, and even cancer. But science tells a much more nuanced story.

This episode continues the carbohydrate series by looking at what the evidence actually shows about carbohydrates, sugar, fiber, and chronic disease risk. Topics include common myths about sugar and diabetes, how carbohydrates influence blood glucose management, the role of fiber in metabolic health, and how dietary patterns affect heart disease and cancer risk.

Chronic diseases are complex and multifactorial. No single nutrient causes them. This episode focuses on distinguishing myths from evidence and understanding how carbohydrate quality and overall dietary patterns play a much larger role than individual foods do.

If you have ever wondered what carbohydrates actually are and why they matter, this episode provides context without oversimplifying the science.

Sugar is one of the most misunderstood parts of nutrition. Some call it poison. Others shrug it off as harmless. The truth is more nuanced. In this episode of Real World Nutrition, we explore the nature of sugar, its role in the body, the distinction between natural and added sugars, and why the quantity is more significant than cutting it out completely. Also covered are recommendations from major health organizations, common myths, the many names sugar hides under, and why nutrition is rarely black or white.
