Ultra-Processed Snacks: What the UK Needs to Know For 2026
The UK is waking up to the real impact of ultra-processed foods. Here’s how to navigate seed oils, gums, additives and “healthy” snacks that aren’t as clean as they seem.
Searches for “ultra-processed foods”, “seed oils”, “what are emulsifiers” and “best natural snacks UK” are trending across Google and TikTok. Consumers want clarity, and most brands aren’t giving it.
Ultra-processed snacks that dominate UK shelves:
- Protein bars with 15–25 ingredients
- Products layered with seed oils (sunflower, rapeseed, soybean)
- Gums + emulsifiers (guar, xanthan, carrageenan)
- Sugar alcohols (maltitol, erythritol)
- Heath snacks layered with artificial sweeteners
- Meat Snacks with Sodium Nitrate
These additives affect digestion, inflammation, energy, and even mood.
What Seed Oils Actually Do in the Body
They’re not “poison” - but they are:
- High in omega-6 fatty acids
- Often oxidised before you eat them
- Linked with inflammation when an imbalance occurs
- Found everywhere in bars, dressings, crisps, sauces
Most processed snacks are built on sunflower or rapeseed oil.
ROAMS stance:
- Zero seed oils.
- Zero emulsifiers.
- Zero gums.
- Zero anything artificial
- Just EU grass-fed beef + spices.

Why Gums and Emulsifiers Matter
These ingredients help ultra-processed bars “hold shape.”
But they can also:
- Disrupt gut lining
- Cause bloating
- Trigger digestive discomfort
- Alter the microbiome
Common culprits:
- Guar gum
- Xanthan gum
- Locust bean gum
- Polysorbate 80
- Carrageenan
Roam bars contain none.
The Problem With Sodium Nitrate in Processed Meat Snacks
Sodium nitrate and sodium nitrite are preservatives commonly found in jerky, biltong, cured meats, supermarket “protein meats,” and many high-street meat snacks. They’re used to extend shelf life, enhance colour, and keep products looking “fresh” for longer, but the health trade-offs are significant.
Why Sodium Nitrate Can Be Harmful
When nitrates are exposed to high heat (cooking, drying, smoking) or mix with amino acids during digestion, they can form nitrosamines, compounds linked to increased inflammation and long-term health risks.
Research suggests sodium nitrates may contribute to:
- Inflammation in the gut and digestive discomfort
- Oxidative stress, which affects energy levels and cellular health
- Microbiome disruption, altering the balance of healthy gut bacteria
- Headaches, lethargy or “post-snack slump”
- Potential long-term disease risk when consumed frequently
These effects are even more noticeable in people with:
- Busy lifestyles
- High stress loads
- High training volume
- Sensitive digestion
