Plant-based meat study sharpens focus on fortification and product design

London School of Hygiene & Tropical Medicine-led research is giving plant-based meat manufacturers a clearer nutritional signal: product substitution can improve overall diet quality, but the category still has work to do on micronutrient consistency and affordability.

The first study, published in Current Developments in Nutrition, looked at what happens when processed meat is replaced with the most popular, the nutritionally strongest, or the most affordable plant-based alternatives available in the UK. Researchers found that even a relatively simple substitution could raise overall fibre intake by 4% to 6%, while reducing saturated fat by 6% to 7% and salt by 3% to 4%. All products assessed met the UK Food Standards Agency’s Nutrient Profiling Model thresholds for a healthy nutritional profile.

A second paper, published in Proceedings of the Nutrition Society, reached a more qualified conclusion. On average, plant-based meat contained more fibre and less saturated fat than conventional meat, but fortification with essential vitamins and minerals was inconsistent across products. That matters because the category is no longer judged solely on whether it lowers meat intake. It is increasingly judged on whether it can function as a nutritionally reliable replacement, especially for nutrients that consumers would otherwise expect from animal-derived foods.

For manufacturers, that moves the discussion onto specification. Much of the early plant-based market was shaped by texture, flavour, and meat mimicry. Those remain central, but the category is maturing into a more exacting phase in which buyers, retailers, and policymakers are paying closer attention to composition. If one product carries iron, iodine, and vitamin B12 while a similar product does not, the category begins to look uneven. That inconsistency becomes more problematic when price is also a barrier. The same research found that while plant-based drinks and yoghurts can be cheaper than their animal-based equivalents, plant-based meat remains more expensive.

Those two issues intersect more than they may first appear. Nutritional improvement is useful only if products are bought regularly enough to influence diets at scale. Price premiums narrow that possibility, particularly when the category is still fighting on taste, cooking performance, and consumer trust. For manufacturers, the temptation may be to simplify labels and ingredient decks in response to clean-label pressure. The difficulty is that cleaner-looking formulations do not automatically deliver stronger nutrition. In some cases, fortification is precisely what makes a product more viable as a direct replacement.

That tension is likely to define the next stage of category development. Plant-based meat is no longer short of concept launches or technical ambition. What it needs now is tighter execution around the fundamentals: sensory quality, stable formulation, meaningful nutrition, and a cost structure that does not confine repeat purchase to a niche consumer base. The days when the category could trade mainly on novelty or broad sustainability messaging are fading. Buyers increasingly want a product that performs on shelf, in the pan, and on the nutrition panel.

The research also complicates the simplistic treatment of plant-based meat as an undifferentiated ultra-processed category. The products assessed did not show the typical nutrient profile associated with less healthy ultra-processed foods. That does not end the debate over processing, but it does suggest that broad classification is a poor guide to product quality. From a manufacturing standpoint, that opens the door to more useful scrutiny: which ingredients, process routes, and fortification strategies actually deliver a better product.

There is a policy angle as well. The Dutch experience, where voluntary standards have driven more widespread fortification, suggests there is room for greater consistency without waiting for a hard regulatory intervention. In the UK, the precedent set for plant-based drinks shows that fortification guidance can move from niche discussion to mainstream public-health policy.

For plant-based meat manufacturers, the challenge now is to treat nutrition as part of product engineering rather than a secondary claim. Fibre, saturated fat, salt, iron, iodine, calcium, and vitamin B12 are not background issues. They are increasingly central to whether the category can move from intermittent trial to durable market share.
