You may be a food addict
Modern processed foods are designed to make us want more – and that’s not healthy.
When we think about diet and obesity, we sometimes encounter the phrase “food addiction”.
It’s a real thing – and science tells us that many ultraprocessed foods are designed to make us crave more.
There is growing evidence that some ultraprocessed foods can trigger behaviours similar to addiction.
Products including chips, sugary drinks, packaged snacks, and ready-made meals are engineered with combinations of refined carbohydrates, fats, salt, and additives that rarely occur in natural foods.
This “perfect mix” can create what researchers describe as an intense, rewarding sensory experience that encourages repeated consumption.
Scientists increasingly recognise that these foods can activate the brain’s reward system in ways comparable to substances such as nicotine or alcohol.
Studies suggest they can drive cravings, loss of control, and continued use despite negative health impacts. These are all behaviours associated with addiction.
Researchers using the Yale Food Addiction Scale estimate that many people show signs of clinical addiction to ultraprocessed foods.
Part of the explanation lies in how these foods are formulated. Food manufacturers carefully calibrate ingredients to reach a “bliss point” – the optimal balance of sugar, salt, and fat that maximises pleasure.
This combination can stimulate dopamine, a brain chemical linked to reward and motivation, reinforcing the desire to eat more.

While scientists continue to debate the precise biological mechanisms, there is broad agreement that ultraprocessed foods are designed to be highly appealing and easy to overconsume.
Health authorities warn that this has serious implications. According to the Australian Government’s HealthDirect webste, ultraprocessed or “junk” foods are typically high in sugar, salt and unhealthy fats but low in essential nutrients such as fibre, vitamins, and minerals.
Diets high in these foods are linked to obesity, type 2 diabetes, cardiovascular disease, and some cancers. The site also notes that eating large amounts of ultraprocessed foods can increase the risk of chronic health problems and early death.
Globally, consumption of ultraprocessed foods has risen sharply, now making up a large share of daily calorie intake in countries including Australia and the United States.
Their convenience, accessibility, and aggressive marketing contribute to this trend, creating an environment where highly rewarding, low-nutrient foods are ubiquitous.
While not all experts agree that food addiction should be classified in the same way as substance dependence, there is growing consensus that ultraprocessed foods can strongly influence eating behaviour.
Understanding how these products affect our brains is increasingly seen as key to addressing rising rates of obesity and diet-related disease.
