(Press-News.org) Scientists are recruiting adults from across the UK to take part in a groundbreaking trial to accurately track what they eat and drink in their daily lives.
The findings of their research could pave the way for better public health strategies to tackle diseases linked to poor diets such as type 2 diabetes, heart disease and some cancers.
Currently diets are measured by people completing complex and time-consuming nutrition surveys themselves and trying to remember exactly what they have eaten, but this can lead to unreliable results.
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.
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.
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.”
The research is funded by a £2.5 million grant provided by the Medical Research Council (MRC) and the Biotechnology and Biological Sciences Research Council (BBSRC).

People are more helpful when in poor environments
2026-02-09
People are more likely to act helpfully in situations where there are poorer choices to give to others, according to a new study that tested willingness to help others in different contexts.
The paper, published in Nature Communications today (Monday 9 February), is the culmination of three studies involving more than 500 participants and led by academics from the University of Birmingham. The team, which also included academics from Oxford University and the University of East Anglia, found that when people were in a poor environment they were surprisingly more likely to help compared to the richer environment.

How big can a planet be? With very large gas giants, it can be hard to tell
2026-02-09
Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don’t have hard surfaces. Jupiter and Saturn are the gas giants in our solar system, but there are many other gas giant exoplanets in our galaxy and some are many times larger than Jupiter. The largest gas giants blur the line between planets and brown dwarfs — those substellar objects, sometimes called “failed stars” because they do not fuse hydrogen.
How do these gas giants form? Was it through core accretion, where solid cores gradually ...
New method measures energy dissipation in the smallest devices
2026-02-09
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That’s harder than it sounds. Memory storage, information processing, and energy use in these technologies involve constant energy flow – systems never settle into thermodynamic balance. To complicate things further, one of the most precise ways to study these processes starts at the smallest scale: the quantum domain.

Have associations between historical redlining and breast cancer survival changed over time?
2026-02-09
Historical redlining, a 1930s–1960s residential segregation policy, has been linked to shorter survival time in people with breast cancer. New research reveals that this association has changed over time, with disparities narrowing until recently. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Under the redlining policy, federal agencies and banks created maps that designated neighborhoods as A (“best”) to D (“hazardous,” colored red ...
Brief, intensive exercise helps patients with panic disorder more than standard care
2026-02-09
Panic attacks are sudden bouts of intense fear without an obvious cause. An estimated 10% of people experience at least one panic attack in their lifetime. But between 2% and 3% of the population have such frequent and severe panic attacks that they meet the criteria for the debilitating condition ‘panic disorder’.
The current standard of care for panic disorder is cognitive behavioral therapy (CBT), with or without antidepressants. A technique of CBT with proven efficacy is ‘interoceptive exposure’, where therapists trigger common ...
How to “green” operating rooms: new guideline advises reduce, reuse, recycle, and rethink
2026-02-09
Reduce, reuse, recycle, and rethink can be applied in Canadian operating rooms (ORs) to increase environmental sustainability, advises a new guideline published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.251192.
As the Canadian health care system produces almost 5% of the country’s greenhouse gas emissions and 200 000 tonnes of other pollutants, many generated in ORs, it makes sense to focus on reducing these harms.
An evidence-based ...
What makes healthy boundaries – and how to implement them – according to a psychotherapist
2026-02-09
In recent years, popular culture has made ‘boundaries’ a saviour, touted as the way to prevent burnout at work and fallout with friends. But how do we make them, and what makes a boundary ‘healthy’?
Psychotherapist Lynn Somerfield suggests that maintaining healthy boundaries around relationships, work and personal beliefs is crucial to good mental health.
In her new book, The Seeds of Change – How Therapists Cultivate Personal Growth, she draws on patient case histories and insights from her ...
UK’s growing synthetic opioid problem: Nitazene deaths could be underestimated by a third
2026-02-09
Deaths due to synthetic opioids nitazenes have likely been underestimated by up to a third.
King’s College London research, published today in Clinical Toxicology, sheds light on the UK’s growing synthetic opioid problem.
The presence of nitazenes on the unregulated drug market has risen steeply in the last seven years – prompting UK and international bodies to issue public health warnings about their use.
Nitazenes are a class of synthetic opioids which can have potencies of up to 500 times that of heroin. They can be readily manufactured at low cost. These potent synthetic opioids were ...
