The call to target ultra-processed food to reduce obesity in Britain is a crucial shift in public health strategy. MPs have rightly clarified that obesity is an engineered outcome, not a failure of willpower. The current 'high in fat, salt or sugar' framework is flawed, as it obscures the primary drivers of weight gain and type 2 diabetes: sugar and refined carbohydrates. Instead, we must focus on the ultra-processed food model itself—products engineered for shelf life, craveability, and margin.
Why Ultra-Processed Food Is the Real Culprit
Decades of British food policy have emphasized low-fat, calorie-controlled approaches that allow manufacturers to replace fat with sweet-tasting substitutes. This has not curbed obesity rates. Ultra-processed foods often contain cheap sugar, refined starch, and additives that trigger overconsumption. The body does not need added sugar at all, yet it has become the cheapest, most heavily advertised ingredient.

Comparing Ultra-Processed vs. Whole Foods
| Category | Ultra-Processed Foods | Whole Foods |
|---|---|---|
| Ingredients | Refined sugars, starches, additives | Natural, single-ingredient items |
| Nutritional Value | Low in fiber, vitamins; high in empty calories | High in fiber, vitamins, minerals |
| Health Impact | Linked to obesity, diabetes, heart disease | Supports weight management and metabolic health |
| Craveability | Engineered for addiction-like response | Natural satiety signals |
Key Takeaways for Consumers
- Read labels: avoid products with long ingredient lists and added sugars.
- Prioritize whole foods like vegetables, fruits, lean proteins, and whole grains.
- Treat occasional items like ice cream or crisps as indulgences, not staples.
- Support policies that incentivize real food over ultra-processed products.
Fixing the Food System
The health select committee's report should push for carbohydrate and sugar reduction, not another blunt fat-and-salt panic. Manufacturers must be held accountable for the ultra-processed food model that dominates shelves. Public awareness and regulatory changes can together reshape Britain's relationship with food.
FAQ
What is ultra-processed food?
Ultra-processed foods are industrial formulations made mostly from substances extracted from foods, often containing additives and little to no whole food. Examples include sugary drinks, packaged snacks, and ready meals.
How does ultra-processed food contribute to obesity?
These foods are designed to be hyper-palatable, cheap, and convenient, leading to overconsumption. They are high in sugar and refined carbs, which spike insulin and promote fat storage, while being low in fiber and protein that signal fullness.
Why is the 'high in fat, salt or sugar' framework inadequate?
It treats fat, salt, and sugar equally, but the evidence points to sugar and refined carbohydrates as primary drivers of obesity and diabetes. This framework allows manufacturers to swap fat for sugar while still labeling products as 'healthier' options.
To truly reduce obesity in Britain, we must target the ultra-processed food system. It's time to treat the underlying engineering, not just the nutritional labels.
