A new study has identified an association between consumption of drinks containing a high amount of sugar and anxiety symptoms in adolescents.
Researchers at Bournemouth University were part of a team involved in reviewing the findings of multiple studies that have investigated people’s diets and their mental health, to establish common findings.
Their results have been published in the Journal of Human Nutrition and Dietetics.
“With increasing concern about adolescent nutrition, most public health initiatives have emphasised the physical consequences of poor dietary habits, such as obesity and type-2 diabetes,” said Dr Chloe Casey, Lecturer in Nutrition and co-author of the study. “However, the mental health implications of diet have been underexplored by comparison, particularly for drinks that are energy dense but low in nutrients,” she added.
Anxiety disorders are a leading cause of mental distress among young people, in 2023 it was estimated that one in five children and young people had a mental health disorder, with anxiety one of the most reported conditions.
The studies investigated by the research team measured sugary drink consumption and mental health of the young people through surveys. Beverages with high amounts of sugar can include fizzy drinks, energy drinks, sugary juices, squashes, sweetened tea and coffee, and flavoured milks.
The results consistently found a link between high levels of sugary drink consumption and anxiety.
The researchers emphasise that because of the nature of the studies they investigated, the findings do not provide evidence that drinking more sugary drinks directly causes anxiety. It is also possible that experiencing symptoms of anxiety leads to some young people consuming more sugary drinks. Or there could be other common factors – for example family life and sleeping disorders – that lead to both increased consumption and symptoms of anxiety.
“Whilst we may not be able to confirm at this stage what the direct cause is, this study has identified an unhealthy connection between consumption of sugary drinks and anxiety disorders in young people,” Dr Casey said.
“Anxiety disorders in adolescence have risen sharply in recent years so it is important to identify lifestyle habits which can be changed to reduce the risk of this trend continuing,” she concluded.
The study was led by former Bournemouth University PhD student, Dr Karim Khaled, who now works at Lebanese American University, Beirut.

An international team of scientists have identified how to pinpoint and predict hotspots for some of the most dangerous species of scorpion in the world.
The researchers have established the key environmental conditions that determine where lethal, venomous arachnids thrive - findings that could help shine a light on flashpoints for scorpion stings in tropical regions across the globe.
The team of scientists used field observations in Africa combined with computer modelling to predict where dangerous scorpion species are most likely to be found and what factors influence their distributions.

Arizona State University researchers will lead a panel discussion on household water insecurity at the American Association for the Advancement of Science (AAAS) Annual Meeting, which takes place in Phoenix next week.
The panel, “Beyond the Tap: Water Insecurity in the United States,” is organized by Patrick Thomson, a research scientist with ASU’s Arizona Water for All project and will be moderated by Regents and President’s Professor Alexandra Brewis from ASU’s School of Human Evolution and Social Change. The session focuses on growing ...
Arizona State University Regents Anne Stone will present research on the evolutionary history of infectious disease at the American Association for the Advancement of Science (AAAS) Annual Meeting, which takes place in Phoenix next week.
Stone’s presentation, “(Re)Emerging Pathogens: Ancient Spillovers Teach Us About Modern Plagues,” examines tuberculosis (TB), a disease that has affected humans and animals for thousands of years. Drawing on genetic analyses of ancient DNA, her research traces how TB moved between species and human populations over time and what those patterns reveal ...
Viruses exist at the boundary between living and non-living matter, while skin is a living interface between physics and biology, making them perfect—but until now overlooked—arenas for testing the interplay between quantum physics, biology and life. That’s according to arguments made by Connor Thompson, a PhD student in microbiology and immunology at the University of British Columbia, in Canada, and Samuel Morriss, a medical doctor based in Melbourne, Australia, whose two essays share the US$30,000 first prize in FQxI’s latest essay competition, presented in partnership with the Paradox Science Institute. The eight winners of the $53,000 competition—which ...
As the U.S. population ages, a growing number of older adults are living alone — a circumstance linked to increased risks of loneliness, social isolation and cognitive decline. Researchers from Arizona State University are addressing these challenges through innovative, technology-enabled interventions designed to improve health, independence and quality of life.
At the 2026 AAAS Annual Meeting, hosted in Phoenix, Arizona State University faculty from the Edson College of Nursing and Health Innovation will lead a panel discussion titled “Tech Solutions for Older Adults Living Alone with Cognitive Decline” ...
Tokyo, Japan – Researchers at Tokyo Metropolitan University have studied how fruit flies tune their development in response to environmental changes (diapause). Studying fruit fly strains from different latitudes across Japan, they showed that the sensitivity to starting reproductive diapause varies smoothly with local conditions. Through genetic sequencing, they found that the timeless (tim) gene plays a key role, adding to growing evidence that diapause is strongly affected by genes regulating circadian rhythm.

CORVALLIS, Ore. – A study of more than 100 kindergarten-age children suggests kids tend to think of snakes differently than they do other animals and that hearing negative or objectifying language about the slithery reptiles might contribute to that way of thinking.
The study also suggests it takes minimal intervention to “inoculate” a child against snake negativity.
The findings, published in Anthrozoös, are important for multiple reasons, explains co-author Jeff Loucks of Oregon State University.
Snakes are reviled in many human cultures but little is known about how children develop feelings of fear and vilification toward an animal ...

Chemotherapy Resistance
Can Chemo-Resistant Cancer Cells Be Resensitized?
A new study from Sylvester researchers may have found a workaround for the long-standing problem of chemotherapy resistance and, in turn, identified an encouraging way to restore the power of widely used chemotherapy drugs. The study, published this month in Genes & Development, explains how blocking a key protein forces damaged cancer cells into a state of uncontrolled transcriptional activity. This action creates ...
Even as misinformation proliferates across the Internet, sites containing low-credibility health information remain relatively scarce and unseen.
That’s according to new research from University of Utah communication scholars who tracked web-surfing activities of more than 1,000 U.S. adults for four weeks. But the findings, published in Nature Aging, illuminate a dark side. Traffic to such sites is concentrated heavily among older adults, especially among those who lean right politically.
This indicates the most vulnerable ...
Adult survivors of childhood cancers are at higher risk for another cancer – such as breast, colorectal, sarcomas and thyroid cancer – that is not a relapse of their original illness. Previous cancer therapies are largely responsible, however up to 13 percent of survivors also have hereditary predisposition that elevates their risk of subsequent cancer. A recent clinical trial found that genetic services via remote centralized telehealth and in collaboration with primary care increased the uptake of genetic ...
