The UK’s healthy food market is changing in 2026.
Protein-rich products, high-fibre foods, beans and pulses, gut-health products and minimally processed ingredients are becoming increasingly visible across British supermarkets. At the same time, consumers remain highly concerned about food prices and ultra-processed foods.
The shift is not simply about fashionable ingredients. Retail sales, consumer research, supermarket product development and Government policy all point towards a broader change in how healthy eating is understood in Britain.
Recent data also suggests that beans, lentils, tofu and tempeh are gaining ground as shoppers look for foods that combine nutrition, value and versatility.

What are the biggest healthy food trends in the UK in 2026?
The most significant healthy food trends currently visible in the UK include:
- Higher-fibre foods
- Protein-rich foods
- Beans, lentils and other pulses
- Tofu and tempeh
- Gut-health products
- Fruit and vegetables
- Minimally processed foods
- Nutrient-dense meals
- Lower-sugar and lower-HFSS products
- Affordable healthy eating
There is strong evidence behind several of these trends.
NielsenIQ reported growth in UK supermarket sales of protein-based and fibre-based foods in early 2026, while more recent NielsenIQ data analysed by Madre Brava showed that sales of beans, pulses, tofu and tempeh increased during the first half of the year.
Meanwhile, Food Standards Agency research shows that consumers themselves are changing their diets, with reducing processed food and increasing fruit and vegetable consumption among the most common health-related changes reported.
1. Fibre is becoming a major UK food trend
Fibre has become one of the most prominent healthy-eating themes of 2026.
The NHS recommends that adults aim for around 30g of fibre a day. Good sources include wholegrains, fruit, vegetables, beans, peas and lentils.
The commercial food market is also responding.
M&S identified fibre as one of its five major health-food trends for 2026 and has used the term “fibremaxxing” to describe growing interest in increasing fibre intake. The retailer’s 2026 health trends also highlight foods providing fibre, vitamins and minerals.
NielsenIQ reported that fibre-based food sales increased by 14.1% in the 26-week period covered by its February 2026 UK supermarket analysis.
That makes fibre particularly interesting because it sits at the intersection of:
- gut health
- digestive health
- heart health
- satiety
- plant-based eating
- wholegrain consumption
However, consumers should not assume that a product labelled “high fibre” is automatically healthier.
Whole foods such as beans, lentils, vegetables, fruit, nuts and wholegrains can provide fibre alongside other nutrients.
What foods are naturally high in fibre?
Examples include:
- lentils
- chickpeas
- kidney beans
- butter beans
- oats
- wholegrain bread
- wholewheat pasta
- brown rice
- vegetables
- fruit
- nuts
- seeds
The trend therefore does not require consumers to buy specialist products.
2. Protein moves into mainstream grocery shopping
Protein is another major UK food trend in 2026.
For years, high-protein products were strongly associated with sports nutrition and bodybuilding. That is changing.
Protein is now appearing across mainstream grocery categories, including:
- yoghurt
- bread
- wraps
- cereals
- ready meals
- snacks
- drinks
- desserts
NielsenIQ reported a 9.6% increase in UK supermarket sales of protein-based foods in its February 2026 analysis.
M&S has identified “protein for all” as one of its five major health trends for the year.
Sainsbury’s has also developed products around protein, fibre and nutrient density, including its Small but Mighty range.
Is high-protein food automatically healthy?
No.
Protein is an important nutrient, but the overall nutritional profile of a food still matters.
A high-protein product can also contain significant amounts of:
- saturated fat
- salt
- free sugars
- calories
For that reason, the UK trend is better understood as greater interest in protein, rather than proof that every high-protein product is a healthy choice.
3. Beans and pulses are making a comeback
One of the most interesting healthy food developments of 2026 is the renewed popularity of beans and pulses.
New analysis published in September 2026 using NielsenIQ sales data found that UK sales of beans, pulses, tofu and tempeh increased by 7.3% in units during the first six months of 2026 compared with the same period a year earlier.
Value sales increased by 10.1%.
The strongest growth was recorded in several simpler plant-protein categories, including dried beans, peas and lentils.
Tofu and tempeh also recorded growth.
This is significant because it suggests that the plant-based food market is not simply disappearing as some highly processed meat alternatives lose momentum.
Instead, consumers may be becoming more interested in traditional foods that naturally provide protein and fibre.
Why are beans becoming popular?
Beans and pulses offer several advantages:
- They can provide protein.
- They are naturally rich in fibre.
- They work in a wide variety of meals.
- Dried pulses can be inexpensive.
- Tinned beans are convenient.
- They can replace some meat in meals.
The renewed interest also coincides with the Food Foundation’s “Bang in Some Beans” campaign, which aims to double UK bean consumption by 2028.
For shoppers, this could make beans one of the most practical healthy-food trends of the year.
4. Gut health remains a major consumer interest
Gut health continues to influence food development in 2026.
M&S lists gut health among its major health-food trends and has expanded products positioned around digestive health, including products containing fibre and live cultures.
The wider market includes:
- kefir
- live-culture yoghurt
- fermented foods
- kimchi
- sauerkraut
- fibre-rich foods
- prebiotic ingredients
- probiotic products
The growing interest in gut health is closely connected to the popularity of fibre.
However, the two should not be treated as identical.
A healthy gut is not created simply by buying a product labelled “gut friendly”. Dietary variety and overall eating patterns remain important.
Are fermented foods a healthy food trend?
Fermented foods are increasingly visible in supermarkets and foodservice.
But individual products vary considerably in nutritional composition.
For example, some fermented products can contain substantial amounts of salt or added sugar.
Consumers therefore still need to check the nutrition information rather than relying on a health claim on the front of the pack.
5. The shift towards minimally processed foods
Another major theme in 2026 is the consumer desire for simpler food.
M&S has identified “minimal ingredients” as one of its five health-food trends.
The trend is closely connected with growing concern about ultra-processed food.
The latest Food Standards Agency consumer research shows that ultra-processed food has become one of the UK’s leading food concerns.
However, “minimal ingredients” and “minimally processed” are not official measures of nutritional quality.
A short ingredient list does not automatically mean that a product is healthier.
The more useful question is:
What is the overall nutritional quality of the food?
That means looking at:
- fibre
- protein
- fruit and vegetables
- saturated fat
- salt
- free sugars
- portion size
rather than judging a product only by the number of ingredients.
6. Fruit and vegetables remain at the centre of healthy eating
Despite the rise of fashionable terms such as “fibremaxxing” and “protein for all”, traditional healthy-eating advice remains important.
The NHS continues to recommend eating at least five portions of fruit and vegetables each day.
Government monitoring continues to track fruit and vegetable consumption as part of England’s Obesity, Physical Activity and Nutrition Profile.
The May 2026 update provides the latest available Government profile covering adult overweight and obesity, physical activity and fruit and vegetable consumption in England.
The Food Standards Agency’s Food and You 2 Wave 11 research also found that 46% of respondents who had changed their diet for health reasons said they had increased their fruit and vegetable consumption.
This is an important reminder that the newest food trends do not replace the basics.
Fruit and vegetables remain a central part of a balanced diet.
7. Ultra-processed food is a major consumer concern
Ultra-processed food has become one of the biggest food conversations in Britain.
The latest FSA Consumer Insights Tracker shows that ultra-processed food was a concern for a large majority of consumers.
The issue is particularly important because it combines:
- nutrition
- food formulation
- consumer trust
- marketing
- food policy
- affordability
The debate should nevertheless be handled carefully.
Not every packaged or processed food is nutritionally equivalent, and “ultra-processed” is not simply another word for “unhealthy”.
For consumers, a more useful approach is to consider the whole diet and nutrition profile of individual products.
Are UK shoppers eating less processed food?
There is evidence that many consumers are trying to do so.
The FSA’s Food and You 2 Wave 11 survey found that 49% of respondents who had made health-related dietary changes reported eating less processed food.
The research covered 5,898 adults and was conducted between May and August 2025.
8. Affordable healthy food is increasingly important
Healthy eating in 2026 cannot be discussed without considering price.
Food prices remain one of the biggest concerns for UK consumers.
The latest FSA consumer research continues to show food prices as a leading concern.
The Food Foundation’s Broken Plate 2026 report also highlighted the affordability gap between healthier and less healthy diets.
This creates an important change in the meaning of “healthy food”.
For many households, the question is not simply:
“What is healthiest?”
It is:
“What is healthy, filling and affordable?”
That is one reason beans, lentils, oats, frozen vegetables and other relatively inexpensive staple foods are becoming increasingly relevant.
Food Future’s recent coverage of UK food inflation also examines how food prices continue to affect household purchasing decisions.
9. Supermarkets are changing their healthy-food strategies
The UK’s major supermarkets are responding to the changing market.
Sainsbury’s
Sainsbury’s has announced an expanded healthy-eating strategy focused on increasing fibre and fruit and vegetable consumption.
The retailer says its ambition is to make healthy eating simpler and more affordable for families.
It has also developed the Small but Mighty range, which uses nutritional criteria including protein, fibre, fruit and vegetables.
M&S
M&S has taken a trend-led approach.
Its 2026 health trends include:
- fibremaxxing
- biohacking
- protein for all
- gut health
- minimal ingredients
The retailer has also introduced more than 90 products as part of its 2026 health-focused product development.
Tesco
Tesco’s online grocery assortment also demonstrates how high-protein products have moved into mainstream shopping categories.
The retailer currently offers high-protein products across several categories, including bread, wraps, cereals, snacks and ready meals.
The important development is not that one retailer has discovered healthy eating.
It is that major supermarkets are increasingly competing around health attributes alongside price, convenience and taste.
10. Government policy is influencing the food market
Healthy eating is becoming a food-policy issue as well as a consumer trend.
On 25 June 2026, the Government published its Healthier Food Targets and Reporting programme.
The programme is intended to support mandatory healthier-food sales reporting for large food businesses and the development of targets aimed at increasing the healthiness of food sales.
The programme applies to England, Northern Ireland and Wales.
This matters because it shifts some responsibility for healthier diets towards the wider food system.
Instead of relying entirely on individual shoppers, policymakers are increasingly looking at:
- product formulation
- food sales
- promotions
- availability
- retail environments
- consumer choice
11. Plant-based eating is becoming more nuanced
Plant-based food is still part of the UK’s healthy-food conversation, but the market is changing.
The latest sales data suggests strong growth in simpler plant-protein categories such as:
- beans
- pulses
- lentils
- tofu
- tempeh
At the same time, some meat-alternative categories have faced weaker sales.
That distinction matters.
The future of plant-based food may not be dominated by imitation burgers and sausages.
Instead, growth may increasingly come from familiar whole or minimally processed foods.
This is also potentially more compatible with the affordability trend.
A bag of dried lentils can form the basis of several meals, while tinned beans can be added to soups, salads, curries, stews and pasta dishes.
12. Nutrient density is becoming more important
Another emerging idea is nutrient density.
Rather than focusing exclusively on whether a meal is low in calories, retailers are increasingly highlighting foods that deliver useful nutrients within a meal.
This can include:
- protein
- fibre
- vitamins
- minerals
- fruit
- vegetables
- wholegrains
Sainsbury’s Small but Mighty range is an example of this approach.
The broader trend suggests that healthy eating is gradually moving away from a simple “low calorie” message towards a more complete view of nutritional quality.
13. Healthy convenience food is becoming mainstream
Consumers still want convenience.
The healthy-food market is therefore not necessarily moving towards cooking everything from scratch.
Instead, supermarkets are developing convenient products with nutritional attributes such as:
- high protein
- higher fibre
- vegetables
- controlled calories
- lower sugar
- lower saturated fat
This creates a new category of healthy convenience.
The opportunity for food manufacturers is significant because consumers increasingly want products that are:
quick + affordable + nutritious + enjoyable.
14. What are the healthiest trends to watch for the rest of 2026?
Based on the current evidence, the strongest trends to watch are:
| Trend | Evidence strength | What is changing |
|---|---|---|
| Fibre | Strong | Retail sales and consumer interest are rising |
| Protein | Strong | High-protein products are moving into mainstream grocery |
| Beans and pulses | Strong and very recent | H1 2026 sales growth |
| Gut health | Strong consumer/retail trend | More kefir, fermented and fibre products |
| Less processed food | Strong consumer evidence | Many shoppers report reducing processed foods |
| Fruit & vegetables | Strong official guidance | Remain central to healthy eating |
| Nutrient density | Emerging | Retailers increasingly promote nutrient-rich meals |
| Minimal ingredients | Emerging | Consumer interest is influencing product development |
| Healthy convenience | Emerging | Retailers are reformulating ready-to-eat options |
| Affordable nutrition | Very important | Food prices remain a major consumer concern |

- Fibre is one of the strongest healthy-food trends in UK grocery retail in 2026.
- Protein has moved beyond specialist sports nutrition and into everyday supermarket categories.
- Beans, pulses, tofu and tempeh have recorded recent sales growth.
- Gut health continues to influence food product development.
- Many consumers are trying to reduce processed foods.
- Fruit and vegetables remain fundamental to official UK healthy-eating guidance.
- Ultra-processed food is a major consumer concern.
- Food affordability is central to the healthy-eating debate.
- Major supermarkets are responding with new health-focused ranges.
- Government policy is increasingly focused on making the wider food system healthier.
Expert Insight
The most important development is arguably the convergence of several trends.
Protein, fibre, plant-based foods, gut health and affordability are increasingly connected rather than separate consumer movements.
Beans and lentils illustrate this particularly well. They can contribute protein and fibre while also being versatile ingredients for relatively inexpensive meals.
The recent sales growth therefore provides a more meaningful signal than simply counting the number of “healthy” products launched by supermarkets.
At the same time, shoppers should be cautious about turning individual trends into rigid dietary rules.
A high-protein label does not automatically make a product healthy. A product with a short ingredient list is not automatically nutritionally superior. Likewise, a food marketed for gut health still needs to be assessed as part of the overall diet.
The strongest evidence continues to support dietary patterns built around a variety of nutritious foods rather than one fashionable ingredient.
Conclusion
The latest healthy food trends in the UK show a market becoming more focused on fibre, protein, plants, gut health, nutrient density and affordability.
The strongest new signal is the renewed interest in beans, pulses, tofu and tempeh. Sales data for the first half of 2026 suggests that shoppers are increasingly choosing simpler plant-protein foods, while supermarket strategies show that fibre and protein are becoming mainstream product-development priorities.
At the same time, consumers remain concerned about ultra-processed food and the cost of groceries.
For UK shoppers, the practical lesson is relatively simple: healthy eating does not need to depend on expensive specialist products or the latest wellness trend.
A diet containing a wide variety of fruit and vegetables, wholegrains, pulses and other nutritious protein sources remains consistent with established healthy-eating guidance.
The biggest food trend of 2026 may therefore be less about discovering a new superfood and more about making everyday food more nutritious, more convenient and more affordable.
