We all enjoy a good slushie every now and then. While they do not add any great nutritional value to our meal, they are a delightful snack made with shredded ice and sugar. To make them more accessible to people who cannot or do not wish to have sugar, there are many sugar free options to pick from. However, a recent study has revealed that sugar-free slushies containing glycerol, which is a sugar alcohol used to maintain their icy texture, can cause severe health problems in young children. The study was published in the journal Archives of Disease in Childhood, it explains that having these sugar free slushies can lead to children having a condition called "glycerol intoxication syndrome". In this condition there is a rapid drop in blood sugar, reduced consciousness, and a buildup of acid in the blood.

Rapid Onset of Symptoms

Kids who drank slushies with glycerol got sick very quickly. Within an hour, they started showing serious symptoms. Their blood sugar would plummet, sometimes dangerously low. Many became confused or lost consciousness, and some even had seizures. Doctors studied 21 children who got sick from these drinks between 2018 and 2024. Most of these kids were very young, seven years old or younger. By the time they got to the hospital, many were in bad shape, either unconscious or barely awake. This quick reaction time makes it especially scary, as parents might not realize the slushy is the cause right away. It's important to recognize these signs fast.

Why is Glycerol Harmful?

According to WebMD Glycerol is a type of naturally occurring alcohol, and it's used in lots of food products. You might find it in protein bars, diet foods, and even sugar-free candies. In slushies, it plays a key role in keeping the drink icy. Usually, slushies use tons of sugar to stop them from freezing completely. But because people are trying to cut back on sugar, companies are using glycerol instead. This is especially true in places with "sugar taxes," where sugary drinks cost more. So, to make sugar-free versions, they add glycerol. This switch means more kids are being exposed to this ingredient, which can be harmful to them.

What Does Glycerol Damage Children's Health?

The study explains that little kids are more at risk from glycerol because their bodies are still growing and developing. Their tiny bodies and young metabolisms might not be able to handle glycerol as well as adults' bodies can. This means that even a small amount can cause a big problem. Also, the amount of glycerol in a slushy can vary, and it's hard to know exactly how much is safe. Factors like how fast they drink it, if they've eaten recently, or if they've been exercising can also make a difference. Even the standard size of a slushy drink can be too much for a small child. This makes it hard to give a safe dose.

Health authorities in the UK and Ireland have already started warning about glycerol in slushies. They suggest that kids under four shouldn't have them at all, and older kids should only have one at most. But doctors are worried that these warnings might not be enough. They point out that it's hard to know how much glycerol is actually in each drink, making it difficult to give safe advice. Parents are being told to be very careful and consider avoiding these drinks altogether for young children. In the US, glycerol is approved for use in food, but parents should still be aware of the potential risks. More research is needed to understand the full impact.

Higher temperatures in the US could increase heat-related heart disease by 200 per cent by 2050, according to an alarming study.

The research, published in JAMA Cardiology, predicts rising temperatures driven by climate change will dramatically increase heat-related heart disease in the US.

It is already known that extreme heat is detrimental to heart health and can potentially trigger heart attacks and other cardiovascular events.

"But this study is the first to map out exactly how bad the problem could get—county by county, across the US. It also highlighted how states with lower median household incomes are likely to face higher heat-related heart disease burden," said Gokul Parameswaran, research associate at the Case Western Reserve School of Medicine's Cardiovascular Research Institute and the study's lead author.

Regional Hot Spots

Researchers analyzed heart disease data in each county in the contiguous US from 2010 to 2016 to develop projections through 2050.

They found that the Pacific Northwest has the highest heat-related heart disease rate in the country. Southern states, however, are projected to see the steepest increases by 2050.

"Climate change is not just an environmental issue—it is a health equity crisis, and prioritizing vulnerable communities must be at the center of any heat mitigation strategy," said Salil Deo, associate professor in the Department of Surgery.

The study also found that aging — independent of temperature increases — will contribute an additional 34 per cent increase in heat-related heart disease by 2050, simply because there will be more older adults by then.

Heat Events In The US

The study comes amidst more frequent heat events in the US, which is also lasting longer, and the temperatures during heat events are going up.

The past 10 years, from 2015 to 2024, were the hottest on record globally. But in cities across the United States, the average rate of extreme heat events increased from two per year in the 1960s to 10 per year between 2010 and 2020, according to Center for Climate and Energy Solutions (C2ES), a Washington-based NGO.

Additionally, as of 2024, the average length of heat-wave season in the US has increased by 46 days since the 1960s.

How Does Heat Raise Heart Risks?

According to the Centers for Disease Control and Prevention, when temperatures rise, the heart must work harder to keep the body cool, and the likelihood of developing sudden clots in the bloodstream increases.

This extra stress on the heart due to high heat may lead to heart attacks or sudden worsening of heart disease, especially in the elderly or those with prior heart conditions.

How To Tackle The Risk

• Expanding green spaces and tree cover in urban areas could help reduce temperature-related adverse effects.
• Expanding access to cooling centers and air-conditioning assistance programs for low-income communities can also help bridge the gap in underserved communities.

"Climate change is not a distant, abstract threat," said Sanjay Rajagopalan, director of the Cardiovascular Research Institute and chief of Cardiovascular Medicine at University Hospitals Harrington Heart & Vascular Institute.

"It is a present and growing danger to the hearts of every American, and it is coming for the most vulnerable among us first. The choices made today about greenhouse gas emissions, urban planning, and health care policy will determine whether tens of thousands of Americans live or die from heat-related heart disease by 2050," he added.

Amid increasing contamination and adulteration of food products, India’s food regulator has introduced new safety standards across a wide range of foods such as besan (gram flour), edible and cold-pressed seed oils, as well as prawns.

The draft regulations by the Food Safety and Standards Authority of India (FSSAI) cover heavy metals, toxins, antibiotic residues, and quality standards for both commonly used foods and emerging edible products, the Times of India reported.

The new regulations are expected to come into force on December 1.

What Has Changed Under The New Rules?

Under the new rules, the FSSAI has:

• Expanded contamination standards related to lead and cadmium to include pulse flours such as besan and packaged mixes in addition to pulses.
• Updated limits for aflatoxins — toxic substances produced by certain fungi — in oils, oilseeds, and ready-to-eat oilseed products.
• Revised testing norms for arsenic in fish oils and updated standards for saffrole, a naturally occurring substance found in foods and beverages containing nutmeg and mace.
• Introduced residue limits for antibiotics such as trimethoprim and oxolinic acid in seafood products, including shrimps, prawns, and fishery products.

New Standards For Seed Oils And Edible Seeds

In a separate draft notification, the FSSAI proposed quality and safety standards for lesser-used edible oils made from chilli, tomato, muskmelon, and okra seeds as demand rises for cold-pressed oils, seed-based snacks, and plant-based nutrition products.

The proposed norms require these oils to remain free from adulteration, harmful impurities, rancidity, and mineral oil contamination, while also prescribing limits for moisture, acidity, and metal content.

The draft rules also cover edible seeds such as watermelon, cucumber, pumpkin, sunflower, sesame, and flaxseed sold in raw, roasted, or salted forms, requiring them to be clean and free from insects, fungus, and visible contamination before sale.

FSSAI has invited public comments on the draft regulations for 60 days before finalization.

Crackdown On Food Adulteration

In Ghaziabad, the state food regulator seized 10 quintals of suspected paneer stored in unhygienic conditions. With contamination risks high, the joint team swiftly sampled the batch and destroyed the entire 1,000 kg consignment.

In Muzaffarnagar, food safety officials inspected an ice cream outlet. The drive focused on ice creams and ice candies to ensure they met regulatory standards. A total of three legal samples were collected.

How Adulterated Foods Can Affect Your Health?

The FSSAI noted that hidden adulterants in everyday food can create serious concerns for consumers.

Food adulteration happens when there is an intentional addition of foreign or inferior substances to original food products.

A 2024 study published in SAGE Open Medicine noted various health impacts of adulterated food, including:

• Cancer
• Lathyrism
• Liver disease
• Cardiac failure
• Kidney disease
• Nervous system-related diseases

The study also noted that adulteration could lead to allergic reactions. Pregnant women, children, and the elderly are more prone to developing illnesses if adulterated food is consumed.

Do you smoke herbal cigarettes believing they are “natural”, “chemical-free”, and “tobacco-free”? You may be mistaken. New research, ahead of World No Tobacco Day 2026, has raised concerns over the growing popularity of herbal cigarettes, suggesting that herbal cigarettes are not safer than conventional cigarettes and may be equally harmful to health.

The new joint study by the Indian Institute of Technology Gandhinagar (IITGN) and the University of Illinois Urbana-Champaign (UIUC), US, has found that herbal cigarettes can produce emissions comparable to — and in some cases more harmful than — those generated by tobacco cigarettes.

The study, published in the Journal of Hazardous Materials, highlight significant health concerns surrounding herbal smoking products, many of which currently fall outside India’s primary tobacco control laws.

Leaf-wrapped Herbal cigarette Most Hazardous

The study compared emissions from two of India’s best-selling tobacco cigarette brands and four popular herbal cigarette varieties containing ingredients such as basil, clove, cinnamon, mint, green tea, water lily, and chamomile.

Two of the herbal products also used tendu (ebony) leaves as wrappers — the same material commonly used in bidis, India’s most consumed smoking product.

Researchers analyzed the physical, chemical, and oxidative properties of mainstream smoke generated from the products. According to the study, herbal cigarette smoke released extremely fine particles and toxic compounds at levels similar to or exceeding those found in tobacco smoke.

“Our findings challenge the widely held belief that tobacco-free means risk-free. Emissions from herbal cigarettes are comparable to or exceed those from tobacco cigarettes on nearly every metric we measured. Leaf-wrapped herbal variants turned out to be the most hazardous of all the samples tested,” said Prof. Sameer Patel, Assistant Professor at IITGN’s Department of Civil Engineering and Chemical Engineering.

Fine Particles And Oxidative Stress

Further, the researchers combusted each cigarette inside a sealed automated two-chamber system designed to mimic human inhalation patterns, to decode particle size, chemical composition, and oxidative potential.

Shockingly, the team found that particles smaller than 500 nanometers — associated with cardiovascular and respiratory diseases — were emitted at nearly 20 per cent higher concentrations in herbal cigarette smoke compared to tobacco smoke.

The study also measured the “oxidative potential” (OP) of smoke particles — a marker of their ability to generate reactive oxygen species that contribute to inflammation, lung damage, and vascular disease.

According to the researchers, particulate matter from herbal cigarettes showed significantly higher oxidative potential than tobacco cigarettes. Tendu-leaf-wrapped variants recorded OP levels nearly 49 per cent higher than paper-wrapped products.

Notably, one basil-filled herbal cigarette marketed as “100% natural” and “chemical-free” showed the highest lead concentration among all products tested.

Prof. Vishal Verma, Associate Professor of Environmental Engineering at UIUC and co-author of the study, said the results are particularly significant because many consumers believe nicotine-free products are less harmful.

“That finding is important because many consumers associate nicotine-free products with reduced harm,” he said.

Concerns Over Regulatory Gaps

Researchers also pointed to regulatory loopholes surrounding herbal cigarettes. India’s Cigarettes and Other Tobacco Products Act (COTPA), 2003, regulates tobacco products through health warnings, advertising restrictions, and public smoking rules. However, many products marketed as tobacco-free do not fall under the same regulatory framework.

Lead author Dr. Alok Kumar Thakur said several herbal cigarette brands claim therapeutic benefits, including relief from cough, anxiety, and sleep problems, despite limited scientific evidence on their safety.

“However, there is limited scientific evidence evaluating the emissions and toxicological impacts of these products,” he said.

The findings also align with the World No Tobacco Day 2026 under the theme, “Unmasking the appeal: countering nicotine and tobacco addiction.”

The researchers stressed the urgent need for evidence-based regulation and stricter oversight of alternative smoking products to prevent misleading health claims and protect public health.
