Diet plays a very important role when it comes to your health. There are many people who have to adhere to strict diets because of certain conditions they have. While the basic understanding that we need all kinds of foods to fulfill our body’s needs, sometimes these foods can also cause harm to your body. For example, lactose intolerant people cannot eat or consume any kind of dairy product as their bodies do not have the necessary compounds, known as lactose, to break down dairy foods. Similarly, there are many foods that may be ok for others to consume, but not for people who have digestive issues like IBS. But this new clinical trial may be able to help us know what food we can eat based on our blood test! The blood test, called inFoods IBS, looks for a special type of antibody in the blood. Antibodies are like tiny soldiers that our bodies make to fight off things that could make us sick.

IBS is a very common problem, affecting a large number of people. Many people know that what they eat can make their IBS symptoms worse, but it's often hard to figure out exactly which foods are the culprits. This is because everyone is different, and what triggers one person might not trigger another. Doctors hear from patients all the time, asking for help in determining which foods are causing their problems. So, finding a reliable way to pinpoint those foods is important. This test is attempting to provide that reliability.

How Does This Blood Test Work?

Basically, the test is looking for an antibody called IgG. When the gut reacts badly to a food, it makes more of this IgG antibody. The test checks for reactions to 18 common foods, like wheat, milk, and certain fruits. If the test finds high levels of the IgG antibody for a certain food, it means that food is likely causing problems. Therefore, the patient should try to remove that food from their diet.

Many people with IBS struggle to find relief from their stomach pain and discomfort. This new study looked at whether a special blood test could help. The idea was to see if the test could tell people which foods were making their IBS worse. The results were encouraging. When people changed their diets based on what the blood test showed, about 60% of them felt less stomach pain. This is better than the 42% who felt better when they just tried a general diet change. This shows that the blood test might be a useful tool for people with IBS to get real relief.

How Does This Personalized Nutrition Approach Work?

Many doctors suggest that people with IBS try elimination diets, where they cut out certain foods to see if their symptoms improve. However, these diets can be very hard to follow, because they often require people to cut out a lot of different foods. Doctors are always looking for ways to give patients care that's tailored to their specific needs. In the case of IBS, that means figuring out exactly which foods each person should avoid.

This blood test is a step in that direction. Experts are calling it a move towards "precision nutrition." This means that instead of giving everyone the same diet advice, doctors could use the blood test to create a personalized plan for each patient. While more research is needed, this test brings hope that doctors will soon be able to give much more precise dietary recommendations to those people that suffer from IBS. While this test is yet to be approved by FDA, it could be a world of comfort and ease for people who suffer with IBS.

As artificial intelligence becomes a go-to source for quick answers, a new University of Oxford-led study on AI chatbots and medical advice is raising serious concerns about how safe it is to rely on these tools for health guidance.

The research suggests that while AI chatbots can provide medical information, their advice is often inaccurate, inconsistent, and difficult for users to interpret, potentially putting people at risk—especially when dealing with symptoms that need urgent care.

What the Oxford Study Found

The study involved 1,300 participants who were given realistic health scenarios, such as experiencing a severe headache or being a new mother feeling constantly exhausted. Participants were divided into two groups: one group used AI chatbots to understand their symptoms and decide next steps, while the other did not.

Researchers then assessed whether participants correctly identified what might be wrong and whether they made appropriate decisions, such as seeing a GP or visiting A&E.

The results were troubling. People who relied on AI frequently failed to identify the severity of their condition and were often unsure about when to seek professional medical help.

Why Chatbot Advice Can Go Wrong

According to the researchers, one major issue is that people don’t always know what to ask. The study found that chatbot responses varied widely depending on how questions were phrased. Even small changes in wording could lead to completely different answers.

The AI often produced a mix of helpful and misleading information, leaving users to decide which advice mattered. Many participants struggled to distinguish between reliable guidance and unnecessary or confusing details.

As one of the study’s authors explained, when an AI lists multiple possible conditions, users are left guessing which one applies to them—precisely the moment where mistakes can happen.

A Dangerous Gap in Symptom Interpretation

Dr Rebecca Payne, lead medical practitioner on the study, warned that asking chatbots about symptoms could be “dangerous”, particularly when users delay seeking professional care based on AI responses.

Dr Adam Mahdi, the study’s senior author, noted that while AI can share medical facts, people often share information gradually and leave out key details—something chatbots struggle to manage effectively.

Bias, Data, and the Limits of AI

Experts also point out that chatbots are trained on existing medical data, which means they may repeat long-standing biases baked into healthcare systems. As one psychiatry expert put it, a chatbot is only as accurate as human clinicians—and humans are far from perfect.

That said, not everyone is pessimistic.

What Comes Next for AI in Healthcare

Digital health experts argue the technology is evolving. Health-specific versions of general AI chatbots have recently been released by major developers, and these could perform differently in future studies.

The consensus among experts is clear: AI in healthcare should focus on improvement, regulation, and guardrails, not replacement of doctors. Used responsibly, it may support healthcare—but without safeguards, it risks doing more harm than good.

This common pregnancy drug could be linked to cancer. Wes Streeting has been urged to launch a public inquiry into a miscarriage drug called Diethylstilbestrol, which, reports say has "ruined and devastated" the lives of countless women. On Monday, the Health Secretary Streeting met victims of the pregnancy drugs, which has been linked to cancer, early menopause and infertility.

What Is Diethylstilbestrol?

Diethylstilbestrol, commonly known as DES, is a synthetic form of female hormone estrogen, which was prescribed to thousands of pregnant women from 1940 to 1970s.

The drug was used to prevent miscarriage, premature labor and complications of pregnancy. This was also used to suppress breast milk production, as an emergency contraception and to treat symptoms of menopause.

What Is The DES Controversy?

In 1971, Diethylstilbestrol (DES) was linked to a rare cancer of the cervix and vagina known as clear cell adenocarcinoma, prompting US regulators to advise that it should no longer be prescribed to pregnant women. Despite this, the drug continued to be given to expectant mothers across parts of Europe until 1978. DES has also since been associated with other cancers, including breast, pancreatic and cervical cancers, The Telegraph reported.

Campaign group DES Justice UK (DJUK) is now urging Health Secretary Wes Streeting to order a public inquiry and introduce an NHS screening programme to identify people who may have been exposed to the drug before birth.

Victims described DES as “one of the biggest pharmaceutical scandals this country has ever seen,” warning that “the impact of this terrible drug cannot be underestimated as it has ruined and devastated so many lives,” according to The Telegraph.

In November, Streeting acknowledged that the “state got it wrong” and issued an apology to those affected. He also advised anyone who believes they may have been exposed to DES to speak to their GP.

Susie Martin, 55, from Manchester, whose mother was prescribed DES during pregnancy, told The Telegraph she has undergone between 20 and 30 operations as a result of the drug’s effects.

“The impact of this terrible drug cannot be underestimated as it has ruined and devastated so many lives, including my own,” she said. “The physical and emotional pain has been unbearable. I live with a constant fear that I will need more surgery or develop cancer—and I am far from the only one.”

Calling DES a “silent scandal,” Martin said she hopes the government’s engagement will lead to concrete action. “While I welcome Mr Streeting meeting us, it will only matter if he commits to meaningful steps for victims of this shameful chapter in British medical history, including a screening programme and a full statutory public inquiry,” she added.

What Is Happening With The DES Victims?

The Telegraph reported that compensation schemes have been set up for DES victims in the US and Netherlands, however, UK does not have one yet.

"There are harrowing accounts of harm caused by the historic use of Diethylstilbestrol (DES). Some women and their relatives are still suffering from the associated risks of this medicine which have been passed down a generation, and haven’t been supported. The Secretary of State has been looking seriously at this legacy issue and carefully considering what more the government can do to better support women and their families who have been impacted. NHS England has alerted all cancer alliances to this issue so that healthcare professionals are aware of the impacts of DES and the existing NHS screening guidance which sets out the arrangements for those who show signs and symptoms of exposure,” said a Department of Health and Social Care spokesman to The Telegraph.

The World Health Organization (WHO)'s Montreal meeting focused on wearable technology like smartwatches and activity trackers as a reliable source of health tracking. The meeting discussed that wearables could in fact generate objective real-time data, which helps governments design targeted and evidence-based health interventions.

Physicians in the Montreal meetings discussed that wrist-worn devices are more reliable than traditional self-reported surveys. This is because the self-reported surveys could underestimate the levels of physical inactivity.

“Metrics such as step count, moderate-to-vigorous physical activity and sedentary time directly correlate with cardiovascular disease, diabetes and mental health outcomes. Having population-level data allows for early and preventive strategies,” said Dr Venkat Nani Kumar, consultant in internal medicine.

WHO Montreal Meeting: How Have Doctors Reacted The Shift To Wearables?

Doctors in India have welcomed this shift to wearable devices as a better way to generate data and make policies. Dr Kiran Madhala, professor at Gandhi Medical College, Secunderabad, said WHO’s shift reflects rapid advances in artificial intelligence and digital health tools, calling it a progressive step towards improved monitoring of physical activity worldwide.

City-based doctors also underlined the need for inclusive validation of devices. “Wearables must recognise varied movement patterns and step equivalents, especially in ageing populations,” a physician said, while stressing the importance of data privacy and ethical use of health information.

WHO Montreal Meeting: What Are Wearable Health Devices?

As per a 2022 study published in JMIR MHealth and UHealth, wearables refer to devices that are worn by individuals. In health care field, they assist with individual monitoring and diagnosis. Wearables are “seamlessly embedded portable computers...worn on the body," notes another 2018 study published in Telematics Informatics.

A 2018 study published in the journal Sensors noted that wearable health devices are increasingly helping people to better monitor their health status both at an activity/fitness level for self health tracking and at a medical level providing more data to clinicians with a potential for earlier diagnostic and guidance of treatment.

WHO Montreal Meeting: What Are Some Examples Of Wearables?
