Chatbot Helps Users Adopt a Low FODMAP Diet
In a randomized controlled trial, they found that chatbot-assisted dietary advice with brief guidance effectively reduced high FODMAP intake, bloating severity, and improved dietary knowledge, particularly in patients with bothersome bloating.
'Chatbot-assisted dietary advice for FODMAPs restriction was feasible and applicable in patients with bloating symptoms that had baseline symptoms of moderate severity,' study chief Pochara Somvanapanich, with the Division of Gastroenterology, Chulalongkorn University and King Chulalongkorn Memorial Hospital, Bangkok, Thailand, told Medscape Medical News.
Somvanapanich, who developed the chatbot algorithm, presented the study results at Digestive Disease Week (DDW) 2025.
More Knowledge, Less Bloating
The trial enrolled 86 adults with disorders of gut-brain interaction experiencing bloating symptoms for more than 6 months and consuming more than seven high-FODMAPs items per week. Half of them had IBS.
At baseline, gastrointestinal (GI) symptoms and the ability to identify FODMAPs were assessed. All participants received a 5-minute consultation on FODMAPs avoidance from a GI fellow and were randomly allocated (stratified by IBS diagnosis and education) into two groups.
The chatbot-assisted group received real-time dietary advice via a chatbot which helped them identify high, low, and non-FODMAP foods from a list of more than 300 ingredients/dishes of Thai and western cuisines.
The control group received only brief advice on high FODMAPs restriction. Both groups used a diary app to log food intake and postprandial symptoms. Baseline bloating, abdominal pain and global symptoms severity were similar between the two groups. Data on 64 participants (32 in each group) were analyzed.
After 4 weeks, significantly more people in the chatbot group than the control group responded — achieving a 30% or greater reduction in daily worst bloating, abdominal pain or global symptoms (19 [59%] vs 10 [31%], P < .05). Responder rates were similar in the IBS and non-IBS subgroups.
Subgroup analysis revealed significant differences between groups only for participants with bothersome bloating, not those with mild bloating severity.
In those with bothersome bloating severity, the chatbot group had a higher response rate (69.5% vs 36.3%) and fewer bloating symptoms ( P < .05). They also had a greater reduction in high FODMAPs intake (10 vs 23 items/week) and demonstrated improved knowledge in identifying FODMAPs ( P < .05).
'Responders in a chatbot group consistently engaged more with the app, performing significantly more weekly item searches than nonresponders ( P < .05),' the authors noted in their conference abstract.
'Our next step is to develop the chatbot-assisted approach for the reintroduction and personalization phase based on messenger applications (including Facebook Messenger and other messaging platforms),' Somvanapanich told Medscape Medical News .
'Once we've gathered enough data to confirm these are working effectively, we definitely plan to create a one-stop service application for FODMAPs dietary advice,' Somvanapanich added.
Lack of Robust Data on Digital GI Health Apps
Commenting on this research for Medscape Medical News , Sidhartha R. Sinha, MD, Director of Digital Health and Innovation, Division of Gastroenterology and Hepatology, Stanford University in Stanford, California, noted that there is a 'notable lack of robust data supporting digital health tools in gastroenterology. Despite hundreds of apps available, very few are supported by well-designed trials.'
'The study demonstrated that chatbot-assisted dietary advice significantly improved bloating symptoms, reduced intake of high-FODMAP foods, and enhanced patients' dietary knowledge compared to brief dietary counseling alone, especially in those with bothersome symptoms,' said Sinha, who wasn't involved in the study.
'Patients actively used the chatbot to manage their symptoms, achieving a higher response rate than those in the control arm who received brief counseling on avoiding high-FODMAP food,' he noted.
Sinha said in his practice at Stanford, 'in the heart of Silicon Valley,' patients do use digital resources to manage their GI symptoms, including diseases like IBS and inflammatory bowel disease (IBD) — and he believes this is 'increasingly common nationally.'
'However, the need for evidence-based tools is critical and the lack here often prevents many practitioners from regularly recommending them to patients. This study aligns well with clinical practice, and supports the use of this particular app to improve IBS symptoms, particularly when access to dietitians is limited. These results support chatbot-assisted dietary management as a feasible, effective, and scalable approach to patient care,' Sinha told Medscape Medical News .

China rushes to build out solar, and emissions edge downward
TALATAN, China (AP) — High on the Tibetan plateau, Chinese government officials last month showed off what they say will be the world's largest solar farm when completed — 610 square kilometers (235 square miles), the size of the American city of Chicago. China has been installing solar panels at a blistering pace, far faster than anywhere else in the world, and the investment is starting to pay off. A study released Thursday found that the country's carbon emissions edged down 1% in the first six months of the year compared to a year earlier, extending a trend that began in March 2024. The good news is China's carbon emissions may have peaked well ahead of a government target of doing so before 2030. But China, the world's biggest emitter of greenhouse gases, will need to bring them down much more sharply to play its part in slowing global climate change. For China to reach its declared goal of carbon neutrality by 2060, emissions would need to fall 3% on average over the next 35 years, said Lauri Myllyvirta, the Finland-based author of the study and lead analyst at the Centre for Research on Energy and Clean Air. 'China needs to get to that 3% territory as soon as possible,' he said. China's emissions have fallen even as it uses more electricity China's emissions have fallen before during economic slowdowns. What's different this time is electricity demand is growing — up 3.7% in the first half of this year — but the increase in power from solar, wind and nuclear has easily outpaced that, according to Myllyvirta, who analyzes the most recent data in a study published on the U.K.-based Carbon Brief website. 'We're talking really for the first time about a structural declining trend in China's emissions,' he said. China installed 212 gigawatts of solar capacity in the first six months of the year, more than America's entire capacity of 178 gigawatts as of the end of 2024, the study said. Electricity from solar has overtaken hydropower in China and is poised to surpass wind this year to become the country's largest source of clean energy. Some 51 gigawatts of wind power was added from January to June. Li Shuo, the director of the China Climate Hub at the Asia Society Policy Institute in Washington, described the plateauing of China's carbon emissions as a turning point in the effort to combat climate change. 'This is a moment of global significance, offering a rare glimmer of hope in an otherwise bleak climate landscape,' he wrote in an email response. It also shows that a country can cut emissions while still growing economically, he said. But Li cautioned that China's heavy reliance on coal remains a serious threat to progress on climate and said the economy needs to shift to less resource-intensive sectors. 'There's still a long road ahead,' he said. One solar farm can power 5 million households A seemingly endless expanse of solar panels stretches toward the horizon on the Tibetan plateau. White two-story buildings rise above them at regular intervals. Sheep graze on the scrubby vegetation that grows under them. Solar panels have been installed on about two-thirds of the land. When completed, it will have more than 7 million panels and be capable of generating enough power for 5 million households. Like many of China's solar and wind farms, it was built in the relatively sparsely populated west. A major challenge is getting electricity to the population centers and factories in China's east. 'The distribution of green energy resources is perfectly misaligned with the current industrial distribution of our country,' Zhang Jinming, the vice governor of Qinghai province, told journalists on a government-organized tour. Part of the solution is building transmission lines traversing the country. One connects Qinghai to Henan province. Two more are planned, including one to Guangdong province in the southeast, almost at the opposite corner of the country. Making full use of the power is hindered by the relatively inflexible way that China's electricity grid is managed, tailored to the steady output of coal plants rather than more variable and less predictable wind and solar, Myllyvirta said. 'This is an issue that the policymakers have recognized and are trying to manage, but it does require big changes to the way coal-fired power plants operate and big changes to the way the transmission network operates,' he said.

China Emissions Fall While Chemicals Emerge as New Hotspot
A surge of renewable power led to declining emissions in China over the first half of the year even as a growing chemicals sector becomes a major new source of heat-trapping gases, according to new research. Carbon dioxide emissions from the world's largest polluter fell 1% on an annual basis from January to June, according to a report from the Centre for Research on Energy and Clean Air. The power sector led the decline, with steel and cement also contributing to the drop.
