The UK snack industry is undergoing a massive reformulation as beloved biscuits and crisps are re-engineered to meet stricter government health rules. From Doritos to digestives, brands are swapping ingredients and tweaking recipes to reduce fat, sugar, and salt. This shift is reshaping the way British snacks are made, with significant implications for manufacturers and consumers alike.
Why Are UK Snacks Being Reformulated?
The primary driver is the UK government's HFSS (high fat, salt, and sugar) regulations, which restrict the advertising and placement of less healthy foods. Since January 2026, paid-for online ads for HFSS products have been banned, pushing companies to make their products 'healthier' to retain marketing flexibility. The goal is to reduce obesity and related health issues by encouraging healthier choices.
Reformulation isn't just about swapping one ingredient for another; it's a complex scientific process. For example, Ritz crackers now contain 80% less saturated fat, achieved by replacing palm oil with sunflower oil. But this change required years of lab testing to maintain the same texture, snap, and taste. Scientists had to adjust for how the cracker responds to heat, moisture, and packaging, ensuring the final product is indistinguishable from the original.
Key Examples of Reformulated Snacks
Several popular snacks have been quietly reformulated:
- Doritos: Reduced saturated fat and salt levels through oil changes and seasoning adjustments.
- Digestives: Lower sugar and salt content while preserving the classic flavor.
- BelVita soft bakes: Sodium cut by 56% to fall outside the 'less healthy' category.
These changes are often invisible to consumers, as the taste and texture remain largely the same. However, the reformulation process is not without challenges, especially when it comes to maintaining consumer acceptance.

The Science Behind Reformulation
Reformulation is a delicate balancing act. Food scientists must reduce unhealthy components without compromising on taste, texture, or shelf life. For biscuits, this means adjusting fat types, sugar levels, and salt content while ensuring the product still 'snaps' and crumbles as expected. Each ingredient change can have ripple effects on the final product, requiring meticulous testing and iteration.
For instance, swapping palm oil for sunflower oil alters the fat profile but also affects the biscuit's crispness. To compensate, scientists might adjust baking times or add starches. Similarly, reducing sugar can impact browning and moisture, so they might use alternative sweeteners or bulking agents. This is why reformulation can take years and significant investment.
Impact on the Food Industry
The reformulation wave has had a profound impact on the food industry. Companies are investing heavily in R&D to ensure their products comply with regulations while remaining competitive. However, the upcoming review of the 'less healthy' formula poses a new threat. The Food and Drink Federation estimates that 80% of reformulated products could fail under the new model, particularly on sugar.
This uncertainty is worrying for manufacturers who have already spent years and millions on reformulation. If the rules change, they may need to go back to the drawing board, potentially leading to higher costs and product shortages. The industry is calling for a stable regulatory environment to encourage long-term investment in healthier products.
Comparison: Old vs. New Snack Formulas
| Snack | Old Formula | New Formula |
|---|---|---|
| Ritz Crackers | Palm oil, higher saturated fat | Sunflower oil, 80% less saturated fat |
| BelVita Soft Bakes | Higher sodium | 56% less sodium |
| Digestives | Higher sugar and salt | Reduced sugar and salt |
What's Next for UK Snacks?
As the government reviews the 'less healthy' formula, the future of snack reformulation is uncertain. Food companies are preparing for potential changes, but they face significant challenges, especially in reducing sugar without compromising taste. Some are exploring new sweeteners or natural alternatives, but these often come with trade-offs.
Consumers can expect continued innovation in healthier snacks, but the pace may slow if regulations become more stringent. In the meantime, the industry remains committed to reformulation as a key strategy to meet both health goals and consumer expectations.
FAQ
What is HFSS?
HFSS stands for high fat, salt, and sugar. It refers to foods that exceed certain thresholds for these nutrients, which are subject to advertising restrictions in the UK.
Why are snacks being reformulated?
Snacks are being reformulated to comply with UK government regulations that restrict the marketing of less healthy foods. By making products healthier, companies can continue advertising them.
Will reformulated snacks taste different?
In most cases, reformulated snacks are designed to taste as close to the original as possible. Manufacturers use advanced techniques to maintain flavor and texture, so most consumers won't notice a difference.
