Prevention

1.4.7 Food innovation and emerging science

The science of nutrition continues to emerge, with novel findings in areas such as the gut microbiome and its role in the pathway to disease causation, the role of supplementation, and the role of personalisation in optimising our diets.

Microbiome

The gut microbiome—composed of trillions of microorganisms residing in our digestive tract—plays a crucial role in the pathway to disease causation from our diets, for example obesity, type 2 diabetes, inflammatory bowel disease and even certain mental health disorders (Valdes et al., 2018). The foods we consume can either support a balanced microbiome or promote dysbiosis, a state of microbial imbalance associated with increased inflammation and impaired immune function, thus underlining the importance of dietary choices in disease prevention and management.

Dietary patterns for gut health include a diverse intake of fibre from whole grains, fruits, vegetables, legumes and nuts, fermented foods such as yoghurt, kefir, sauerkraut and kimchi, and limiting red meat, excess sugar and alcohol which can disrupt the gut ecosystem. Fortification of foods and the use of dietary supplements may support gut health, although the evidence remains nascent. Products containing prebiotics- non-digestible fibres that feed beneficial bacteria, foods and supplements with probiotics, which contain live microorganisms, and postbiotics—bioactive compounds produced by probiotic bacteria— have some evidence of anti-inflammatory effects and improved gut barrier function.

The microbiome and its impact on healthy ageing is covered in more detail in the Innovation in Prevention Chapter.

Personalisation of Diets

Personalisation of diets represents the next frontier in nutrition, as advances in diagnostic tools now allow individuals to better understand their unique response to certain foods. Personalised nutrition, which takes into account one’s unique biological profile—factors such as lifestyle, dietary habits, genotype, and the gut microbiome, is increasingly recognised for its potential to enhance health outcomes and longevity. Tailoring dietary recommendations to an individual’s unique biological profile could lead to more effective prevention and management of chronic diseases, including obesity, type 2 diabetes, and cardiovascular conditions. For example, studies have demonstrated that individuals respond differently to the same foods due to variations in their gut microbiota and genetic makeup, highlighting the limitations of one-size-fits-all dietary guidelines (Valdes et al., 2018).

By leveraging advances in diagnostic tools—such as genetic testing and microbiome sequencing—personalised nutrition strategies can optimise diet quality, improve metabolic health, and reduce inflammation, thereby supporting longer, healthier lives. This approach is supported by emerging research linking personal dietary interventions to improved clinical outcomes and greater adherence to healthy eating patterns (Valdes et al., 2018).

Personalised nutrition offerings include companies like Nutrigenomix and Zoe. Nutrigenomix provides genetic testing services that generate tailored nutrition advice based on an individual’s DNA, helping users understand their unique nutrient needs and potential sensitivities (Nutrigenomix, 2025). Zoe employs gut microbiome profiling and blood sugar monitoring to deliver bespoke dietary recommendations aimed at improving gut health, energy levels, and long-term disease prevention (Zoe, 2025). Findings from the PREDICT study, a large-scale research initiative led by Zoe with academic partners, revealed that people metabolise the same foods differently due to factors such as their gut microbiome, genetics, and lifestyle, and that personalised nutrition can more effectively optimise metabolic health and reduce disease risk compared to standard dietary advice (Berry et al., 2020).

The integration of personalised nutrition into mainstream healthcare is expected to play a pivotal role in preventive medicine and healthy ageing.

Food Technology

Technology has begun to transform how consumers engage with food. Technology tools are increasingly being integrated into day-to-day food purchasing and decision-making, empowering consumers to make healthier and more informed choices.

Digital food mapping and delivery services have become essential in addressing food deserts and reducing barriers to access. In the UK, new digital mapping systems now direct mobile greengrocers such as the “Queen of Greens” bus to areas with limited healthy food options, ensuring that fresh produce efficiently reaches communities most in need (Queen of Greens).

Online supermarkets and food stores, often integrated with physical retail outlets, are also leveraging technology to expand food choice and accessibility. The rise of these hybrid models has been particularly impactful for disadvantaged populations, enhancing spatial equality and offering convenient access to a wider range of nutritious foods.

AI is increasingly being harnessed by digital platforms to personalise the food purchasing experience. AI-driven recommendation systems analyse customer preferences and behaviours, enabling food retailers and restaurants to provide healthier, tailored menu options and shopping suggestions, which support consumers in making more health-conscious decisions.

Connected food traceability and Internet of Things (IoT) technologies are further transforming the food system by ensuring quality, safety, and transparency from farm to table. Blockchain-enabled platforms and sensor-driven logistics monitor the freshness and provenance of food products, which is especially critical for perishable items destined for deprived or remote areas.

Innovations like airtight plastic silos—piloted by the World Food Programme in Uganda —demonstrate how technology can reduce post-harvest losses, improve food storage, and support better nutrition in lower-income communities (WFP, 2025).

Additionally, the emergence of ‘ghost kitchens’ and virtual restaurants is streamlining the production of healthy meal kits, allowing for rapid and scalable delivery of nutritious meals to a broader audience.

Emerging and Future Innovations

Looking ahead, the next wave of food innovation promises to fundamentally reshape how we grow, understand, and consume nutrition. Emerging technologies such as precision agriculture, vertical farming, and synthetic biology are set to deliver sustainable, resource-efficient food solutions tailored to both urban centres and underserved regions. At the same time, advances in biometrics, augmented reality, and computational nutrition will transform the way individuals interact with their diets, making nutrition more adaptive, personalized, and engaging.

Meanwhile, system-level innovations—like blockchain-enabled transparency, integrated digital platforms, and open-source knowledge sharing—are laying the groundwork for more equitable, resilient, and trustworthy food systems. Together, these innovations point toward a future where healthy food access is smarter, more sustainable, and deeply connected to both individual and community well-being. Some examples of innovation being developed include:

• Precision agriculture & vertical farming: Automation, robotics, drones, and stacked indoor growing systems will deliver fresh produce to urban centers and food deserts with minimal resource use.
• Computational nutrition & synthetic biology: AI and machine learning will create next-generation, nutritionally-optimised foods—including plant-based and synthetic options with tailored health benefits for different populations.
• Augmented reality for education: Future food service experiences will use AR to visualise the nutritional impact of menu choices, supporting behaviour change through interactive learning.
• Personal biometrics and adaptive meal planning: Non-invasive sensors and apps will soon adapt food and nutrition advice in real time to an individual’s biology and health goals.lacai
• Open-source knowledge sharing and affordable tech: Platforms for sharing low-cost, locally-appropriate agricultural and storage technology will empower smallholder farmers and entrepreneurs, connecting them to resources previously out of reach.lifestyle.sustainability-directory
• Food blockchain for full transparency: Blockchain solutions ensuring total traceability and proof of provenance for healthy foods will increase consumer trust and encourage responsible sourcing across the food supply chain.
• Integrated ecosystem platforms: Platforms that unite logistics, menu planning, stock management and consumer feedback into one system will enable real-time response to community needs and rapidly scale best practices.
