(Press-News.org) Calorie labels on restaurant menus are negatively impacting people with eating disorders, according to a new study published today in the BMJ Public Health.
The review, which is the first of its kind, is led by researchers at King’s College London. It found that individuals who have been diagnosed with an eating disorder changed their behaviours if presented with a menu featuring calorie labels.
This included avoiding restaurants, triggering eating disorder thoughts and paying more attention to calorie labels as identified by eye tracking research.
The research found that some people with eating disorders reported that seeing menu labels reinforced their eating disorder beliefs.
The study evaluated existing research to help build a picture of how nutritional labels on menus impact people with a lived experience of eating disorders or disordered eating. It reviewed 16 studies from the UK, US, Canada and Saudi Arabia which included 8,074 participants in total.
The study highlights that people with eating disorders can feel that eating disorders are perceived as less important in the light of obesity prevention policies.
However, physical health cannot be measured by a single indicator such as weight. Some argue that calorie labels can be seen as a blunt instrument to fix a complicated problem and that people with eating disorders could be losing out.
Food labelling came into force in England in 2022. Restaurants, take-aways and cafes with 250 employees or more must display the calories of the food and drink they sell on menus, online menus and take-away platforms. The measure was an attempt to curb rising obesity levels. The United States and Canada have also made calorie displays mandatory, however, few policies targeting obesity have considered the potential impact on eating disorders.
The eating disorder charity Beat estimates that at least 1.25 million people in the UK have an eating disorder. The number of people admitted to hospital with an eating disorder has risen approximately 7% each year since 2005 – 2006.
Senior author Dr Tom Jewell, Lecturer in Mental Health Nursing at King’s College London, said: “Our study highlights that people with lived experience of eating disorders are frustrated at being left out of the conversation around calorie labels.
“Striking a balance between the positive and harmful impacts of calorie labels on menus is vital in any public health policies. Policymakers should consider the impact on both obesity and eating disorders when making decisions about nutrition labelling. A recent review found that calorie labelling has a modest effect on people’s behaviour but this needs to be counterbalanced with the potential harm it does for people with eating disorders.”
Co-author Dr Nora Trompeter, Research Fellow University College London, said: “Our study provides an important addition to the evidence base around calorie labels. Typically, there is a lot of focus on whether policies are effective in reducing obesity, but it is also critical to investigate whether these policies inadvertently harm people with eating disorders. Our review also shows that more research is needed to fully understand the impact of calorie labels on individuals with eating disorders. For example, none of the studies included young people.”
The paper, titled ‘Impact of out-of-home nutrition labelling on people with eating disorders: a systematic review and meta synthesis”, is published in British Medical Journal Public Health.

Artificial intelligence model identifies potential risk genes for Parkinson’s disease
2025-01-28
Researchers from the Cleveland Clinic Genome Center have successfully applied advanced artificial intelligence (AI) genetics models to Parkinson’s disease. Researchers identified genetic factors in progression and FDA-approved drugs that can potentially be repurposed for PD treatment.
The npj Parkinson’s Disease report uses an approach called “systems biology,” which uses AI to integrate and analyze multiple different forms of information from genetic, proteomic, pharmaceutical and patient datasets to identify patterns that may not be obvious from analyzing ...

New avenues in quantum research: supramolecular qubit candidates detected
2025-01-28
Qubits are the basic building blocks of information processing in quantum technology. An important research question is what material they will actually consist of in technical applications. Molecular spin qubits are considered promising qubit candidates for molecular spintronics, in particular for quantum sensing. The materials studied here can be stimulated by light; this creates a second spin centre and, subsequently, a light-induced quartet state. Until now, research has assumed that the interaction between two spin centres can only be strong enough for ...

New clues to the mechanism behind food tolerance and allergies
2025-01-28
With every bite of food we take, our intestinal immune system must make a big decision. Tasked with defending us from foreign pathogens, these exquisitely sensitive cells somehow distinguish friend from foe—destroying invaders while tolerating food and helpful bacteria. How the gut separates the good from the bad has long puzzled scientists.
Now, new research identifies specific gut cell types that communicate with T cells—prompting them to tolerate, attack, or simply ignore—and explains how these opposing responses are triggered. The findings, published in Science, give scientists ...

Moffitt Research advocates for routine brain MRI screening in asymptomatic late stage breast cancer patients
2025-01-28
TAMPA, Fla. (Jan. 28, 2025) — A new study led by researchers at Moffitt Cancer Center shows that asymptomatic brain metastasis is more common in stage 4 breast cancer patients than previously believed. The study, published in Neuro-Oncology, suggests that doctors may need to rethink current screening guidelines for detecting brain metastasis in patients without symptoms.
Researchers examined 101 asymptomatic patients diagnosed with stage 4 breast cancer, including triple-negative, HER2-positive and hormone receptor-positive/HER2-negative ...

PROVIDENCE, R.I. [Brown University] — A study by researchers at the Brown University School of Public Health shows that nearly half of all primary care providers (PCPs) in the United States are affiliated with hospitals, while the number of PCPs affiliated with private equity firms is growing and concentrated in certain regional markets.
Compared with PCPs at independent practices, those affiliated with hospitals or private equity firms charged higher prices for the same services.
The findings were published in JAMA Health Forum.

Western Kenyan farmers favor restoring land with native trees. Yet barriers remain
2025-01-28
African nations have grand ambitions to green up landscapes with trees; the Kenyan government, for example, launched an initiative to plant 15 billion trees by 2032. The hope is that new trees could help fight desertification, create opportunities for livelihood diversification, support nutritional diets, restore biodiversity in highly degraded land and capture planet-heating carbon. Restoring lands using trees could empower millions whose livelihoods depend on working the land while generating multiple environmental and social benefits.
Yet tree planting projects often fall short because ...
