Is your teenager skipping breakfast? Why is that happening and what can you do? As per the data from the Centers for Disease Control and Prevention (CDC), which surveyed adolescent health and well-being found that 1 in 4 students in high school ate breakfast, which means 3 in 4 high school students are not eating their breakfast. This data is as per the 2023 survey.

What Did The Study Intend?

The report describes a 10-year long trend and also recent changes among the two years. The study delved deeper into adolescents' dietary, physical activity and sleep behaviors. The study is also based on a national youth risk behavior survey of a representative sample of students from grade nine to 12.

What Did The Study Find?

The study found that while high school students drank slightly less soda and sports drinks and consumed more water, other healthy eating habits declined. In 2023, only 27% of students ate breakfast every day in the past week. The numbers were even lower for female students, with just 22% eating breakfast daily, compared to 32% of male students. Boys were also more likely to eat fruits and vegetables daily and drink water at least three times a day. Poor mental health and lack of physical activity have also been linked to skipping breakfast.

The other findings included a survey across 10-year period, where a decrease in the percentage of students eating fruits from 65% to 55%, eating vegetables, from 61% to 58%, and having breakfast daily from 38% to 27% was noted.

However, there was a positive trend among this, which was in children drinking plain water at least three times a day, which increased from 49% to 54% from when the survey began in 2015.. There were fewer students who also said that they drank soda in 2023 than in 2013. On an average, in 2013, around 22% students avoided soda, whereas in 2023, 31% students avoided it.

The report also emphasized that a healthy diet, along with daily physical activity and sufficient sleep further contributes to a healthy lifestyle. “The 10-year trends from 2013 to 2023 also show a decline in healthy dietary, physical activity, and sleep behaviors,” the survey reported.

Why Do High School Students Skip Breakfast?

While there is no one straightforward answer to it, psychologists and those who study children, believe that for many high school going kids, it is the easiest time to skip a meal. This is because they are caught between rushing to school, or not just that hungry in the morning. So for them, to sit down to have a breakfast may seem hassle and something they would have to take time out from their busy schedule. They at this age also prioritize their extra-curricular activities.

There has also been a shift in their circadian rhythm, and most teens cannot fall asleep before 11 pm, or even at midnight. Which means they wake up tired and struggle to do things right in the morning, which is why they choose to skip breakfast or give extra minutes to any other activities.

There is of course another, more popular reason, to lose weight. While experts and studies, like the one published in the Journal of Nutrition that found skipping breakfast leads to higher levels of hunger hormones, the students still feel the need to do this. However, it could lead to a slow metabolism, prompt the body to conserve energy and burn fewer calories, weight gain and deprive yo off the essential nutrients like calcium, iron, and vitamin D.

Without a morning breakfast, your blood sugar might drop too, which can increase irritability and stress, along with including the risk of depression in teenage.

Anthropic CEO Dario Amodei has claimed that cancer, Alzheimer's disease, heart disease and mental illness could become “relics of the past” in less than a decade, thanks to artificial intelligence (AI).

The AI company has kicked off the roadshow for its US initial public offering (IPO), seeking to raise up to $64.4 billion at a valuation of around $1 trillion. The listing could mark the first public offering by a frontier AI lab.

In the company's IPO roadshow video, Amodei spoke about AI's potential to transform human health, describing a future in which diseases that have long challenged medicine could be overcome.

"I think if we do this right, we can create an age of miracles where humanity is able to solve problems that have eluded us for millennia," he said.

Amodei also addressed the risks associated with AI and invited investors to join the company's next phase of growth.

"We have to make sure that all the risks, all the ways that things can go wrong with this technology, we very carefully address those risks as we bring the benefits, and as we have a viable business at the same time".

Amodei isn't alone. His promise is echoed by other AI leaders including Elon Musk and Google's AI boss Demis Hassabis.

However, not everybody is convinced. Cognitive scientist Gary Marcus, and cardiologist and digital medicine expert Eric Topol point out that current AI models lack the deep causal and biological understanding required to reliably yield breakthrough cures, and as of 2026, no AI-designed drug has achieved full clinical adoption.

"Setting an unattainable objective. I wish it would come true, but curing all these diseases in the next 10 years is impossible. And I'm very optimistic about the impact of AI for improving health," said Topol, in a post on X.

Marcus added that "most likely none of these will be 'relics of the past in ten years'”.

This is not the first time Amodei has spoken about AI's potential to transform healthcare. In a post on X, he wrote: “I think it will actually be possible to cure most human disease in ~5-10 years.”

In two of his essays, Amodei discussed how advanced AI could accelerate biological and medical research, potentially compressing 50–100 years of scientific progress into five to 10 years.

His predictions have covered several major health conditions, including:

• Cancer
• Alzheimer's disease
• Genetic diseases
• Heart disease, diabetes and obesity
• Schizophrenia
• Major depression

He has also discussed the possibility of AI helping humans live significantly longer.

Major technology companies, including Google, are increasingly expanding their presence in healthcare through AI-powered tools and services. However, the growing use of AI in medicine also raises questions about patient safety, privacy and accountability.

The World Health Organization (WHO) has called for stronger ethical oversight of AI-related health research.

In a recent report, WHO warned that rapid advances in AI are creating challenges around privacy, bias, fairness, transparency and accountability. It said existing research ethics systems may need additional expertise to assess risks associated with AI and large datasets.

Dr Rajeev Jayadevan, former president of IMA Cochin and convener of the Research Cell, Kerala, told HealthandMe that AI-driven research, particularly when it involves large datasets crossing national borders, may require ethics committees to include experts in computer science, data ethics and bioinformatics.

“Ethics Committees by themselves will need to be upgraded to incorporate computer scientists, data ethicists, and bioinformaticians.”

WHO also said oversight should extend beyond ethics committees to researchers, funders, scientific journals, data governance bodies, professional societies and regulators.

Delhi continues to battle high PM2.5 levels, even as a new study estimates that meeting the World Health Organization's (WHO) air quality guidelines could prevent or postpone 9.4 million deaths annually across 136 low- and middle-income countries (LMICs).

Following Diwali celebrations on November 8, PM2.5 concentrations in several parts of the capital reportedly exceeded 66 times the WHO's recommended 24-hour guideline. By November 11, Delhi's AQI had improved to below 300, in the 'poor' category, after several days in the 'very poor' and 'severe' categories.

Led by University of Cambridge researchers, the modelling study also found that cleaner air could reduce disease burden, healthcare costs and productivity losses.

What Did The Study Find?

Published in Environment International, the study assessed the health and economic benefits of reducing PM₂.₅ and nitrogen dioxide (NO₂) levels across 136 LMICs.

Researchers used pollution, population and health data to model the impact of meeting WHO air quality guidelines and interim targets.

The findings suggest that meeting WHO guidelines could:

• Prevent or postpone 9.4 million deaths annually linked to PM₂.₅
• Prevent or postpone 1.1 million deaths linked to NO₂
• Reduce deaths associated with PM₂.₅ by an estimated 6.6 million and those associated with NO₂ by 435,000, even under less stringent interim targets

Meeting PM₂.₅ guidelines could also mean fewer new cases of:

• COPD: 2.8 million
• Dementia: 1.1 million
• Coronary heart disease: 7.3 million
• Stroke: 2.3 million

The researchers also estimated substantial economic benefits from meeting PM₂.₅ guidelines.

Annual direct medical cost savings could include:

• $11.8 billion for coronary heart disease
• $5.9 billion for stroke
• $8.6 billion for dementia

Productivity gains could reach $17.9 billion for stroke, $18.1 billion for COPD and $5.3 billion for coronary heart disease annually.

"Meeting the WHO's air quality guideline values will not be straightforward, but low- and middle-income countries have a critical opportunity to shape healthier futures as their populations grow and their cities expand," said Dr Haneen Khreis of IMS Epidemiology at Cambridge.

She called for better decisions on transport, urban planning and energy, saying these could significantly improve air quality and reduce pollution-related diseases.

What Causes PM2.5 And NO₂ Pollution?

Outdoor air pollution is a major environmental health risk, linked to respiratory and cardiovascular diseases, including asthma, COPD, heart disease and stroke, as well as dementia.

In 2021, the WHO revised its air quality guidelines, setting recommended limits for pollutants including PM₂.₅ and NO₂.

PM₂.₅ consists of particles measuring 2.5 micrometers or smaller. They can travel deep into the lungs. Major sources include vehicle exhaust, power plants, industrial emissions and construction dust. These particles can also form through chemical reactions in the atmosphere.

NO₂ is mainly produced by burning fossil fuels. Sources include vehicle exhaust, industrial emissions and gas stoves and heaters.

Air pollution is a particularly serious challenge in LMICs, where rapid urbanisation, economic development and increasing vehicle use have contributed to poor air quality.

Policymakers attending the 31st Conference of the Parties (COP31) in Türkiye must put health at the centre of every climate negotiation, Professor Marina Romanello, Executive Director of the Lancet Countdown, told HealthandMe in an exclusive interview.

Marina, who led the 2026 Lancet Countdown on Health and Climate Change report released ahead of COP31, outlined the growing health consequences of global warming and the urgent need for stronger climate action.

Drawing on findings from the report, Marina warned that climate inaction is putting lives, livelihoods and public health at risk.

The report noted that climate commitments made since the Paris Agreement have delivered measurable health benefits, but progress remains too slow and uneven.

“One of the things that we are calling for negotiators to realise is that when they go to COP, they're not just negotiating budgets or carbon emissions or degrees of heating. What they're negotiating is people's health,” Marina told HealthandMe.

“They're negotiating how many people die from climate change. They're negotiating how many of our children will grow in these dangerous environments and have less of a chance in life.”

She stressed the need to recognise that climate change is not just an environmental issue.

“It's important to be very clear that climate change is not just a problem of the inanimate world or even of nature and polar bears. It's a problem of people here and today, and that our failure to act is costing people's lives, livelihood and health.”

Health Must Be Included Across All COP Negotiations

Marina, who is also a researcher at University College London's Institute for Global Health, urged policymakers to integrate health into all COP31 discussions rather than confining it to side events.

“We're also calling for countries not just to have climate change as one of the action agenda items and side events, but to actually consider climate change throughout their whole negotiations. Every negotiation stream needs to have health considerations so that we are aware of the hazards and the dangers that we're dealing with here.”

Countries Must Go Beyond COP Commitments

Marina described COP as “a baseline” and “a starting point”, stressing that countries could go much further than the commitments agreed at the conference.

She cited India as an example of a country that stands to gain significantly from accelerating its climate transition, pointing to its natural resources, technological capabilities and opportunities to improve public health.

“In a country like India, where you have so many natural resources, where you have such impressive technology development, where you have so many opportunities from healthier air, improving access to energy, improving the transition towards more resilient, sustainable food systems, you are standing to win so massively from an accelerated transition at a country level.”

Marina also pointed out that countries rarely account for the health implications of their mitigation and adaptation plans. These include both potential negative impacts and the significant health benefits that stronger climate action could deliver.

Taking these benefits into account, she told HealthandMe, that it could increase the overall return on investment and make climate action more cost-effective.

Three Policy Interventions Governments Must Prioritise

Marina outlined three key areas for government action at COP31:

1. Phase Out Fossil Fuels

Governments must prioritise phasing out fossil fuel use, particularly in urban centres where people live, she said.

“That will reduce the burden of air pollution and will mean that people have much less burden of chronic conditions and much less exacerbation of those conditions that they already have.”

2. Strengthen Healthcare Systems

Marina called for health systems to be equipped to respond to climate hazards and for healthcare professionals to receive training on climate change and health.

“They should know how to recommend better care and better preventative measures to their patients.”

3. Accelerate Emissions Reductions

Marina stressed that reducing greenhouse gas emissions must remain a priority for every country.

“We absolutely need to stop our emissions, our greenhouse gas emissions. Every country needs to pursue efforts to reduce their greenhouse gas emissions. It's a global health imperative.”

She added: “Reducing our greenhouse gas emissions in line with the Paris Agreement, redoubling efforts to mitigate climate change is a health imperative.”
