Precision Nutrition Through AI and Biomonitoring

March 1, 2026 2

AI cameras and biomarkers are setting a new standard for nutrition research, providing accurate tracking of daily diets.

Precision Nutrition Through AI and Biomonitoring

Scientists are currently recruiting participants across the UK for the SODIAT-2 trial, a landmark study designed to achieve accurate dietary tracking in real-world settings. The novel trial was designed by scientists from Aberystwyth University. ‘SODIAT-2’ stands for Software for Objective Dietary Intake Assessment Technology (Phase 2) (1^✔ ✔Trusted Source

The SODIAT-2 trial moves beyond traditional methods, such as nutrition surveys, which often suffer from memory bias and unreliable data. This groundbreaking trial utilizes innovative health technologies such as AI wearable cameras, metabolic biomarkers, and digital reporting apps to accurately monitor daily dietary intake.

The findings open new ways to transform public health strategies and improve precision nutrition. By providing a better understanding of eating habits, researchers aim to develop more effective interventions to tackle chronic conditions, including type 2 diabetes, cardiovascular disease, and various cancers.

Additional Evidence for the Study

The study evaluates passive monitoring via wearable cameras and sensors. It proves that automated tracking reduces human error and under-reporting compared to traditional food diaries (2^✔ ✔Trusted Source

How Blood and Urine Analysis Reveal Real-Time Health

In their bid to find more reliable ways of tracking people’s diet, researchers are using a combination of innovative tools – including wearable cameras, blood monitoring devices and metabolomic analysis of urine samples, combined with apps for self-reporting.

The SODIAT-2 study is part of a wider five-year research project led by Aberystwyth University in collaboration with experts at the University of Reading, the University of Cambridge and Imperial College London.

A total of 133 adults are being recruited from all parts of the UK to take part in a five-week programme monitoring exactly what they eat and drink. Participants will:

Wear camera glasses to record what they eat and drink
Provide blood and urine samples collected in their own homes to show what their bodies absorb from food
Complete simplified online food and drink questionnaires on their eating habits

By comparing these methods, researchers aim to find out which combination of tools work best for studying diets in real life.

Accurate Dietary Records Help Shape Public Health Advice and Future Policies

Dr. Manfred Beckmann, lead Principal Investigator from the Department of Life Sciences at Aberystwyth University said:

“One of the problems facing nutrition researchers is getting a true picture of people’s eating habits. To date, most studies have relied on participants remembering and recording the details of their meals but memory can be unreliable and hence the data is not always robust. Additionally, people often change their diet when they know they’re being observed.”

“By developing a new methodology, we aim to get a much more accurate record of people’s diets which will help inform how governments and policy makers assess the success of efforts to improve people’s health and give better dietary advice.”

Why Multi-Modal Dietary Tracking is Essential for Precision Nutrition

Dr. Amanda J Lloyd from the Department of Life Sciences at Aberystwyth University added:

“There is currently no single tool which can capture precisely every element of what we eat and drink, so we are employing a combination of techniques. The benefit of using urine and blood samples to test for ‘markers’ of food and drinks is that they give us objective data.”

“Wearable cameras combined with AI software, and new simplified online tools for self-reporting also offer great potential to record diets.

“We have already put our methodology to the test in a pilot study carried out in two controlled laboratory environments but we will now see how effective our new tools are in monitoring exactly what people eat and drink in their daily lives and in comfort of their own homes.”
