Ultra-processed food is the most heavily processed category in the food supply, engineered to sell rather than to nourish, and much of it is built from the sweeteners and oils processed out of the corn surplus. Eating it degrades the gut microbiome.
Not all food is equally processed, and the most processed category contributes directly to gut dysfunction. The purpose of ultra-processing is not nutrition. It is to create branded, convenient, durable, hyperpalatable products that sell.
The industry is doing what it is structured to do
The food industry has a fiduciary responsibility to produce profit for its shareholders. It is meeting that obligation. The downstream cost to public health is not on its balance sheet, and it is bankrupting most westernized societies.
America does not have a healthcare system so much as a sick-maintenance arrangement. Weight loss is a primary concern for a large share of the population, and the industry positioned to address it has not produced a solution — which is unsurprising, since the same food supply generates the demand.
Monocropping and the surplus
By 1967 the American corn farm was growing nearly three times as much corn as thirty years earlier. That mono-cropped surplus was fed to livestock to increase production and processed into the sweeteners and oils that now saturate the food supply.
Megafarms increasingly rely on monocropping, which depletes soil of beneficial microelements in order to maximize yield. The food produced from depleted soil is not nutritionally equivalent to what preceded it, and the difference does not appear on any label.
What ultra-processing does to the gut
Processed food consumption degrades the intrinsic gut microbiome. That depletion is associated with the rising prevalence of complex conditions — allergies, autoimmune disease, anxiety and mood disorders — whose incidence has moved in step with the industrialization of the food supply.
Titanium dioxide and the additives nobody consented to
Titanium dioxide nanoparticles, 28 to 1158 nm, are a common whitening agent long treated as inert and classified as an excipient — a pharmacologically inactive substance. Nanoparticle behavior is not the same as bulk behavior, and the assumption of inertness has not aged well. It is present in products most people would not think of as containing an engineered nanomaterial.
Vending machines in elementary schools
The prevalence of vending machines stocking soda in schools, particularly elementary schools, is difficult to defend on any health ground. Sodas are made largely with high-fructose corn syrup, delivered in liquid form to children whose metabolic trajectory is being set.
Weight-loss programs now market to children. The attention to the problem is welcome; the fact that a commercial weight programme is the vehicle says something about how far the underlying food supply has gone unaddressed.
What went wrong
A research investment in the 1960s that led to selling more sugar also, plausibly, contributed to sickening a large share of the population. Industry-funded science shaped dietary guidance for decades, and the guidance shaped what a generation ate.
Malnutrition of excess
The United States has a malnutrition crisis that is not caused by insufficient food. People once died of famine; they now die of excess. It is still malnutrition — calories are abundant and the micronutrients that accompany real food are not.
For contrast: prehistoric humans ate bone marrow 400,000 years ago, and marrow together with cranial contents were among the few reliably nutrient-dense foods available. The species is not adapted to what replaced them.
