🧬 Foundational Nutrients: How the Body Uses Fuel

Before nourishment becomes energy, structure, or regulation, the body first has to recognize what it has been given.

Foundational nutrients—macronutrients, micronutrients, and fiber—are not simply “fuel” in the mechanical sense. They are biological signals that tell the body how to allocate resources, which systems to prioritize, and how to maintain balance over time.

This section is not about how much you need or how to calculate intake.

It is about understanding what these nutrients communicate once they enter the body.
