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.

You have probably seen “net carbs” on food labels or heard the term in low-carb and keto spaces. But what does it actually mean, and does it matter?

In this episode, we break down what carbohydrates are, how net carbs are calculated, where the concept came from, and why it is not formally recognized in nutrition science. We also discuss blood sugar, fiber, sugar alcohols, food marketing, and what matters more than chasing a net carb number.

If you have ever wondered whether net carbs are helpful or just another diet trend, this episode will give you the clarity you need.

Understanding nutrition starts with understanding nutrients.

The episode also covers phytochemicals, food groups, and how nutrients work together with our eating patterns in real life.

Raw milk is gaining attention as a so-called natural or superior alternative to pasteurized milk. This episode examines the science, safety standards, and public health data behind those claims. Topics include what raw milk is, why it is restricted in many states, how pasteurization works, and who is most at risk from unpasteurized dairy. The evidence behind alleged benefits is reviewed alongside the very real risks. Get the facts for informed choices.

Ultra-processed foods get talked about a lot, but most of the conversations skip the basics. This episode breaks down what “processed” actually means, how the NOVA classification system works, why it is controversial, and what matters for real life eating. This is not a fear-based take on food. It offers a grounded, practical look at how food processing affects nutrition, health, and decision-making. Includes examples, common misunderstandings, and take-home points that help people make realistic choices.
