The physiology of digestion considered with relation to the principles of dietetics

Delving into the inner workings of the human body, this work explains how the process of digestion underpins every food choice we make. It presents the science of how nutrients are broken down, absorbed, and turned into the energy that fuels daily life, while keeping the language clear enough for anyone without a medical background to follow.

The first section unpacks the sensations of hunger and thirst, showing how they arise in the brain and signal the body’s needs. It then moves on to describe the role of the stomach, the balance of waste and repair, and the ways in which appetite can be influenced by activity, illness, and habit. Practical observations illustrate how ignoring these natural cues can lead to poor health, offering readers a solid foundation for sensible eating.

Written with an eye toward everyday relevance, the revised edition adds fresh material while preserving the detailed explanations that make the physiology of digestion both understandable and useful for improving one’s own well‑being.
