Ivan Kairatov is a biopharma expert with a profound understanding of industrial food engineering and its parallels with pharmacological addiction. With an extensive background in research and development, he has spent years analyzing how technological innovations in the food industry impact human biology and the brain’s reward circuitry. His work focuses on the intersection of nutrition, biochemistry, and public health policy, offering a unique perspective on how modern manufacturing mirrors the addictive design strategies once used by the tobacco industry.
The discussion explores the biological mechanisms behind food addiction, specifically how refined carbohydrates and fats are engineered to trigger massive dopamine spikes. We delve into the metabolic impact of “predigested” food structures, the deceptive nature of health-washing labels, and the sophisticated “dose optimization” used to override satiety. Kairatov also outlines potential regulatory frameworks inspired by tobacco control and provides practical advice for individuals looking to reclaim their health from ultra-processed environments.
Some industrial foods trigger dopamine responses that match or exceed those of nicotine. How does the specific combination of refined carbohydrates and fats alter the brain’s reward circuitry, and what biological markers distinguish this experience from eating whole foods?
In our research, we see that the brain’s mesolimbic dopamine pathway reacts to ultra-processed foods in a way that is strikingly similar to its reaction to drugs. While whole foods like bananas, which have about 23% sugar, cause a controlled release of energy, industrial products can reach up to 81% sugar by weight. When these refined carbohydrates are combined with high fat—often seen in chocolate or pizza where fat makes up 35% of the content—they synergize to more than triple dopamine levels in the reward circuits. Specifically, while nicotine typically raises dopamine signaling 150% to 250% above baseline, high concentrations of sucrose can push that response up to 300%. This massive surge creates a biological “high” that whole foods, which generally increase dopamine by a modest 120% to 140%, simply cannot match.
Modern manufacturing often involves “predigesting” ingredients by stripping away the natural food matrix to ensure rapid absorption. What are the metabolic consequences of this accelerated delivery speed, and how does this process drive the cycle of blood sugar crashes and subsequent cravings?
The industrial food matrix is essentially destroyed through mechanical and chemical “pre-chewing” and “pre-salivating,” which means the body doesn’t have to do the work of breaking it down. This engineering ensures a rapid delivery speed, where reinforcing elements hit the brain almost immediately after ingestion. This lightning-fast absorption causes an unnatural spike in blood glucose, which is inevitably followed by a sharp crash. This metabolic “crash” mimics the sensations of nicotine withdrawal, triggering an intense biological craving for the next “hit” to stabilize the system. Unlike natural foods that offer sustained energy and steady dopamine, these engineered products trap the consumer in a physiological loop of highs and lows.
Products labeled as “low-fat” or “sugar-free” often retain their habit-forming qualities despite these modifications. In what ways do these specific marketing tactics influence consumer behavior, and what regulatory steps are needed to ensure that labels accurately reflect the addictive potential of a product?
These tactics are a form of “health-washing” that we previously witnessed with the marketing of “light” or “low-tar” cigarettes. By labeling a product as “sugar-free” or “added fiber,” the industry creates a “health halo” that encourages consumers to lower their guard, even though the addictive potential remains high due to other additives or textures. These reformulations often evade regulatory oversight because they appear to reduce harm on paper while maintaining the same neural reinforcement. We need a regulatory shift where products are assessed not just by their individual nutrient counts, but by their overall engineering and addictive potential. Labels should clearly disclose the degree of processing and the presence of additives that are known to delink taste from actual nutritional value.
Industrial food design utilizes “dose optimization” to create intense pleasure without reaching a point of satiety. How does this engineering override the body’s natural fullness signals, and what specific additives are most effective at delinking the sensation of taste from actual nutritional value?
Dose optimization is a sophisticated technique used to find the “bliss point”—the exact concentration of salt, sugar, and fat that produces maximal pleasure without triggering the body’s natural “stop” signals. By using amplifying additives, manufacturers can create a sensory boost that is incredibly potent but very transient, ensuring the pleasure fades before the stomach can signal fullness. This hedonic engineering ensures a rapid decline in sensory pleasure, which immediately induces a craving for more. These additives effectively hijack the gut-brain axis, making the brain believe it is receiving vital nutrients when it is actually consuming empty calories. This disconnect disables the natural feedback systems that have evolved over millennia to prevent overeating.
Public health initiatives previously used taxation and advertising limits to change the cultural image of cigarettes. How could these same strategies be applied to the food industry, and what are the primary obstacles to implementing such policies on a global scale?
The transition from viewing cigarettes as a social norm to a health hazard was achieved through aggressive taxation, strict labeling, and a complete ban on certain types of advertising. We can apply this same blueprint to ultra-processed foods by taxing products with the highest addictive potential and limiting their marketing, especially to children. However, the primary obstacle is the global nature of these corporations; when regulations tighten in industrialized nations, these companies often shift their focus to emerging markets where regulations are weaker. To be effective, these policies must be pursued by governments on a global scale to prevent a repeat of the tobacco industry’s international expansion. We must move beyond “industry self-regulation” and implement legally binding limits on how these products are sold and displayed.
Traditional food processing, such as fermentation, preserves the structure of food, whereas modern ultra-processing destroys it. What are the long-term health risks associated with a diet dominated by these engineered structures, and what step-by-step changes can individuals make to recalibrate their taste buds?
A diet dominated by these engineered structures is linked to higher risks for cardiometabolic disease, cancer, and neurodegenerative disorders, as the body is not designed to handle such frequent, intense metabolic shocks. To recalibrate, individuals must first recognize that their environment—filled with microwaves, vending machines, and delivery apps—is designed to satisfy cravings instantly. Step one is to reintroduce whole foods that have an intact matrix, such as stone-ground grains or fermented dairy, which provide slower, sustained energy. Step two is to consciously reduce the frequency of highly engineered snacks, allowing the dopamine receptors in the brain to down-regulate and become sensitive to natural flavors again. Finally, replacing convenience-driven habits with traditional cooking methods can help restore the natural link between taste and satiety.
What is your forecast for the regulation and public perception of ultraprocessed foods?
I forecast that within the next decade, we will see a massive shift in public perception where the most engineered ultra-processed foods are viewed with the same skepticism and caution as tobacco products. Governments will likely move toward “addictive substance” frameworks for certain food categories, leading to mandatory front-of-pack warning labels and significant restrictions on digital marketing. As the link between these products and chronic, preventable diseases becomes even more undeniable through ongoing research, we will see a rise in legal actions against manufacturers for deceptive engineering. The era of treating all calories as equal is coming to an end, and a new era of biological transparency in the food industry is just beginning.
