Nutrition 101. Carbohydrates : What They Are, What They Contain, and What They Do to Your Body (en Inglés) - Alberto Robles

Carbohydrates are one of the most misunderstood parts of nutrition-but they do not have to be confusing.

Nutrition 101: Carbohydrates is a clear, science-first guide to sugars, starches, fiber, glucose, insulin, glycogen, and the foods that contain them. Instead of promoting a low-carb, high-carb, or other one-size-fits-all diet, this book explains what carbohydrates actually are, how your body processes them, and how context changes their effects.

Inside, you will learn how to:

• Understand the chemistry of simple sugars, starches, and fiber

• Follow carbohydrate digestion from your first bite to absorption in the bloodstream

• Understand how glucose is used for energy and converted into ATP

• See how insulin, glucagon, and glycogen regulate fuel after meals and between them

• Understand the different roles of liver and muscle glycogen

• Learn how fiber supports digestion, gut health, fullness, and blood-sugar regulation

• Compare whole grains and refined grains and understand what processing changes

• Recognize major carbohydrate sources in fruits, vegetables, grains, legumes, dairy, and processed foods

• Distinguish naturally occurring sugars from added sugars and understand why the food matrix matters

• Use glycemic index and glycemic load as useful information without treating them as rigid rules

• Understand why carbohydrate needs change with activity level, exercise, and athletic training

• Read Nutrition Facts labels for total carbohydrate, fiber, sugars, added sugars, and serving size

• Evaluate common myths about carbs, fruit sugar, bread, nighttime eating, insulin, and weight gain

• Make practical food choices based on quality, context, activity, and overall dietary patterns

The goal is not to label carbohydrates as good or bad. It is to understand how different carbohydrate foods behave and how they can fit into a balanced approach to eating.

Designed for health-conscious readers, students, active adults, and anyone tired of conflicting advice about carbs, sugar, insulin, blood glucose, or low-carbohydrate diets.

Understand the science. Read the labels. Question the myths. Make informed choices without fearing carbohydrates.
