From Grain to Disease

A 150-year story

For roughly 10,000 years, humans ate grain in its whole, coarsely ground, often fermented form — metabolically a very different food from what fills shelves today. Bran, germ, and fibre were intact, slowing glucose absorption and feeding the gut microbiome. Chronic metabolic disease at population scale was largely absent.

Then in the 1870s, the industrial steel roller mill changed everything. It stripped grain to pure white endosperm — naked starch — cheaply and at scale. The fibre, magnesium, and everything else that modulated glycaemic impact was gone.

The result: the pancreas is chronically overworked, insulin resistance builds silently over decades, and conditions once rare — Type 2 diabetes, hypertension, obesity, fatty liver disease — became the statistical norm.

"The food did not become more plentiful. It became unrecognisable."
