UK Study Exposes “Plant-Based” Additive Overload

Empty grocery store shelves with a few snack items remaining

The “healthy” plant-based swap in your fridge probably has twice as many additives as the food it replaced, and that simple fact should change how you read every label from now on.

Story Snapshot

First-of-its-kind UK supermarket study found plant-based alternatives used 199 additives vs 100 in animal-based foods.
Plant-based products had more ingredients overall and a wider mix of approved E-numbers than their counterparts.
Dairy, meat, and fish substitutes carried the biggest additive load, while regular dairy in the sample used none.
All additives were legally approved, but experts warn that “safe on paper” is not the same as “smart to eat every day”.

Plant-Based Swaps Are More Engineered Than You Think

A team at the Institute for Optimum Nutrition pulled 71 matched pairs of foods from one major United Kingdom supermarket: things like milk, yogurt, brownies, lasagna, meat, fish, and mayonnaise. Each plant-based product had a direct animal-based counterpart. They were not comparing lentils to steak. They compared oat “milk” to cow’s milk, vegan nuggets to chicken, dairy-free spreads to butter. Then they simply counted what was on the labels.

Across those 71 pairs, plant-based items used 199 food additives. The animal-based versions used 100. Plant-based products also listed 1,566 total ingredients versus 1,110 for the animal-based range. That is 456 extra ingredients spread across the vegan and vegetarian options. That is not “plants versus meat.” It is “engineered food versus simpler food,” even when both sit in the same “health” aisle.

Dairy And Meat Alternatives Carry The Heaviest Additive Burden

The biggest gaps showed up in dairy, meat, and fish replacements. Plant-based cheeses and milks carried the heaviest additive loads, while the animal-based dairy products in the sample used no additives at all. Regular milk and standard cheese were just food. Their vegan stand-ins leaned on stabilizers, emulsifiers, flavorings, and colorings to mimic texture and taste. If you have ever wondered why oat milk foams like cow’s milk in your coffee, now you know: it often needs chemistry help.

Plant-based products also drew on a wider mix of E-numbers: 39 different approved additives compared with 31 in animal-based foods. E-numbers are codes for ingredients that the European Union and United Kingdom have signed off as legal. Twenty of these appeared in both groups, but 19 were unique to the plant-based side. That means not only more additives but also different ones, many of them used to rebuild familiar mouthfeel from plant proteins, starches, and oils.

Regulators Say “Safe,” But Safety Is Not The Whole Story

The senior author, Joseph Whittaker, went out of his way to say that more additives “does not necessarily mean an increased health risk”. He is right on the narrow point. Every one of the 199 plant-based additives, and all 100 in the animal-based foods, complied with United Kingdom food safety rules. The United Kingdom uses a “positive list” system. Only additives that pass a scientific risk assessment are allowed, and they must stay within set limits. On paper, these ingredients are safe at typical doses.

European Food Safety Authority is even required to re-check older additives approved before 2009, so the list is not frozen in time. British guidance also bans several dyes and chemicals that raised health flags, including some yellow and red dyes and certain oils. On that level, the reassurance is real. The United Kingdom is not the United States, where companies can self-declare ingredients as “generally recognized as safe” with much looser oversight.

The Catch: Ultra-Processed “Health” Foods And Everyday Exposure

Legal does not mean wise. The study did not measure how much of each additive was in the food, how often people eat these products, or any health outcomes. It only counted presence. That is a major scientific limit, but it is also a cultural warning. Many of these items fall into the ultra-processed food category that now worries heart doctors and obesity researchers. A separate evidence map on novel plant-based foods found that, overall, they tend to beat animal-based foods on health and environmental measures, but quality varies by product. A vegan burger built from pea protein, salt, and spices is one thing. A plant-based cheese with a long list of thickeners, flavor enhancers, and colors is another.

Mainstream nutrition voices walk a careful line. Rhiannon Lambert points out that some plant-based meat alternatives, even when ultra-processed, may still lower cancer risk if they replace processed red meat. On the other side, Marion Nestle has spent years warning that food companies fight hard to keep additives that help shelf life and bright colors, even when consumers push back. That tension shows up here. Plant-based brands must deliver “just like meat or dairy” on texture and taste. Additives are the quiet tools they use to hit that promise.
