Everything you know about healthy eating is built on a foundation of approximately 150 chemicals. Proteins, fats, carbohydrates, vitamins, minerals — the pillars of modern nutritional science represent less than 1% of the chemical compounds actually present in the food you eat. The other 99% is almost entirely uncharted territory.
That is the central revelation in a feature written by Professor David Benton, Professor Emeritus of Human and Health Sciences at Swansea University, published in The Conversation and republished by ScienceDaily on June 17, 2026. In it, Professor Benton argues that the nutrition science of the past century has been working with an incomplete — and in some ways fundamentally misleading — map of the food landscape, and that a new generation of research may finally be equipped to fill in what he and others call "nutritional dark matter."
