Timothy had always been health-conscious. After years of social drinking, she decided to quit alcohol for good. But giving up the ritual of sipping on a drink at social gatherings felt impossible. That's when alcohol-free beer and wine seemed like the perfect alternative—offering the taste and experience without the intoxication. However, what Sarah didn't realize was that these supposedly "harmless" drinks might still be affecting her liver in ways she hadn't anticipated.

With a global shift toward healthier choices, the rise of alcohol-free beverages has been fuelled. Do these drinks, however, live up to their promise of being risk-free? New research shows that while they may eliminate the dangers of intoxication, they still pose metabolic and liver-related risks, which calls for moderation in the long run.

What Happens in your Body within 10 Minutes of Drinking Alcohol-Free Beverages?

The first time you take a sip of an alcohol-free beverage, your body responds almost instantly. Anshul Singh, Lead Clinical Nutritionist and Dietetics Department says, "In as little as 10 minutes, your taste buds have picked up on the flavors, and your brain might even get a placebo effect, giving you the sensation that you're about to be drunk. Some alcohol-free drinks have up to 0.5% ABV, which goes into the bloodstream in minute quantities but will probably not affect you in any significant way."

By the 30-minute mark, your body has metabolized the sugars, artificial sweeteners, or additives in the drink. "Some people may experience a mild insulin spike, which can cause temporary energy boosts. Some non-alcoholic drinks also contain fermentation byproducts or botanical extracts that mimic the sedative effects of alcohol, causing slight drowsiness or relaxation," adds Anshul.

After 60 minutes, most of the drink has been metabolized. Although there is no risk of intoxication, repeated consumption can subtly affect metabolism, gut health, and even trigger cravings for alcohol among those in recovery. Those sensitive to sugar, caffeine, or preservatives might experience even more pronounced effects over time.

How Alcohol-Free Drinks Affect Your Gut and Liver Connection

Your liver and gut health are connected, forming what is called the gut-liver axis. Anshul emphasises, "Even though drinks without alcohol seem harmless, they usually contain sugars, artificial sweeteners, and fermentation byproducts that can disturb this delicate balance."

• High sugar content may lead to insulin resistance, inflammation, and fat accumulation in the liver.
• Artificial sweeteners may change the gut microbiota, causing metabolic imbalances.
• Preservatives and artificial flavors can also enhance gut permeability, thus potentially leading to leaky gut syndrome.

Long-term consumption of these drinks may gradually affect digestion, liver detoxification, and overall metabolic health, making moderation necessary.

Do Alcohol-Free Drinks Still Trigger Liver Enzymes?

Even though these nonalcoholic beverages contain virtually insignificant alcohol, the liver processes them as well. "These small concentrations of alcohol-which may go as high as 0.5% ABV-trigger the liver's detoxification pathways but only at much weaker intensities compared to ordinary alcoholic drinks. But the added sugars, artificial sweeteners, and preservatives in the products could pose significant pressure on liver functions over the long term," explains Anshul.

High sugar intake causes insulin resistance, which can lead to the buildup of fat in the liver and increase the risk of developing NAFLD. Some fermentation byproducts in these beverages also trigger oxidative stress, which puts extra pressure on the liver. Though occasional consumption will not pose a significant threat, regular consumption might lead to chronic liver stress and metabolic imbalance.

Do Non-Alcoholic Beverages Affect Liver Detoxification?

Although trace amounts of alcohol exist in alcohol-free beer and wine, the body will still have to metabolize them. The body employs the same enzymatic pathways used for alcoholic beverages but at a much lower intensity. However, the added sugars, preservatives, and fermentation byproducts present their own set of challenges:

• Mild inflammation to the liver due to the additives and byproducts within the drinks.
• Insulin resistance resulting from excessive sugar intake, causing fat accumulation in the liver.
• Detoxification pathways are overburdened, and impairment of liver function occurs gradually.

Alcohol-free drinks do not cause the liver to become overwhelmed as traditional alcohol does, although it does have a lower, but still important, risk for someone who is drinking too much. For someone with a problem of liver disease or metabolic syndrome, limiting alcohol-free drinks is also important.

Should You Drink Alcohol-Free Beverages?

Alcoholic beverages have always been a dangerous drink, but the safer option for those who want to avoid intoxication. However, it is not totally risk-free. Its impact on metabolism, gut health, and liver function cannot be ignored. Although they are not harmful at first, their consumption over a long period leads to insulin resistance, liver stress, and imbalance in the gut.

For the consumers who love these drinks, moderation is the way forward. The expert shares, "The choice of brands with the least additives, lower sugar, and natural ingredients will reduce risks. In addition, supplementing with a diet that is rich in antioxidants, fiber, and hydration can complement the liver in general."

For most, thought that adopting alcohol-free beverages was a healthier decision. On discovering their side effects on liver health, though, she learned to limit its intake and settle for alternatives that included infused sparkling water, herbal teas, or even kombucha with controlled sugar levels.

The bottom line? Alcohol-free doesn't mean consequence-free. The best way to achieve long-term health is by paying attention to what goes into the body and yet still enjoy social rituals of preference.

An international team of researchers has developed an artificial intelligence (AI)-based tool that can significantly improve care for glaucoma -- a leading cause of irreversible blindness worldwide, according to a study published in The Lancet Primary Care journal today.

Researchers led by those from the University of Lisbon in Portugal found that the AI-based screening tool halved the number of unnecessary referrals for glaucoma.

The study, released during the Glaucoma Awareness Week, also showed an accuracy level at par with human eye doctors.

"The high accuracy at excluding people without glaucoma is especially important, as false alarms can lead to unnecessary hospital visits, patient anxiety, and added strain on healthcare services," the researchers said.

According to the researchers, AI-based screening could:

• support earlier detection,
• reduce unnecessary specialist referrals,
• prevent avoidable vision loss,
• can be integrated into routine primary care in a cost-effective way

Key Findings

The study was carried out at a single screening center in Lisbon, Portugal, in 2023.

The experts screened 671 adults aged 55-65 for glaucoma via the AI tool, analyzing images of the eyes. The images were then independently graded by six glaucoma experts.

The AI-tool:

• referred 66 people (9.8 percent) vs 118 referrals (18.0 percent) by the eye doctors,
• diagnosed glaucoma in 40 participants (6.4 percent).
• It correctly identified 78 percent of people who truly had glaucoma, vs 75 percent identified by the eye doctors
• Correctly ruled out the disease in 95 percent of people, vs 91 percent by eye doctors

While modelling studies suggest that screening could substantially reduce glaucoma-related visual impairment and blindness, barriers include the need for specialised diagnostic equipment and trained personnel, particularly in low- and middle-income countries, and the intrinsically low positive predictive value of screening tests.

In such a scenario, the new study showed that "AI may provide a more viable option than population-wide screening", which may seem impractical.

What Is Glaucoma?

Glaucoma is a chronic disease that affects an estimated 80 million individuals globally, according to the World Glaucoma Association.

It is a progressive, degenerative disorder of the optic nerve that produces characteristic visual field damage.

The disease stems from a long asymptomatic phase, resulting in substantial underdiagnosis and delayed treatment.

Even in high-income countries, up to 50 percent of individuals with glaucoma remain undiagnosed, frequently presenting moderate to advanced disease at first detection.

By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma.

When to see a doctor for glaucoma:

• Vision suddenly gets blurry
• Severe eye pain
• Headache
• Nausea
• Vomiting
• Rainbow-colored rings or halos around lights

In adults, long periods of sleep deprivation has been linked to problems such as weakened immunity, weight gain, depression, and an increased risk of dementia. However, scientists are now paying closer attention to how sleep affects the brain much earlier in life.

However, a new University of North Carolina School of Medicine study suggests that disrupted sleep during early childhood may interfere with key stages of brain development and asl well as increase the risk of developing autism.

Why Sleep Matters For The Developing Brain

Sleep plays a crucial role in helping these synapses form and strengthen. During sleep, the brain organizes and stabilizes these neural connections, shaping the foundation for future brain function. If sleep is repeatedly disrupted during this delicate stage of development, the process may be affected.

Frequent waking or sleep disturbances could interfere with how these neural connections are formed, potentially influencing behavior and cognitive abilities later in life.

The Link Between Sleep And Autism

“The unique effects of sleep loss during development are largely unexplored,” Diering said. “Our data show that babies and children are more vulnerable to the negative effects of sleep disruption. We also found that sleep loss during this crucial period of time can negatively interact with underlying genetic risk for autism spectrum disorder.”

Sleep problems are already known to be common in people with autism. In fact, sleep disruption has been reported in more than 80 percent of individuals with autism spectrum disorder. However, researchers have long debated whether these sleep issues are a cause of the disorder or a consequence of it. Understanding how sleep interacts with brain development could help scientists detect autism earlier and potentially develop new treatment strategies.

Studying Sleep Disruption In Early Life

In earlier work conducted in 2022, researchers examined how sleep disruption during early life might interact with genetic factors linked to autism. Using mouse models, they disrupted sleep during the third week of life, a developmental stage roughly comparable to ages one to two in humans.

The study found that sleep disruption during this period produced long lasting behavioral changes. Male mice that were genetically vulnerable to autism showed deficits in social behavior later in life. These results suggested that sleep disruption during critical stages of development may interact with genetic risk factors in ways that shape long term behavior.

Younger Brains Respond Differently To Sleep Loss

To investigate further, researchers studied how developing and adult mice respond differently to sleep deprivation.

Using specially designed housing systems equipped with sensitive sensors, scientists tracked the animals’ breathing and movement. This allowed them to determine when the mice were awake and when they were asleep.

The researchers observed that adult mice were able to compensate for lost sleep. After experiencing sleep deprivation, the adults increased their sleep later during their normal active period. This process, known as sleep rebound, allowed them to recover some of the lost rest.

Younger mice behaved very differently. They showed no sleep rebound at all, meaning they did not compensate for the sleep they had lost. This finding suggests that younger brains may be far more vulnerable to the effects of sleep disruption.

The consequences were also visible in cognitive performance. Sleep deprived young mice performed poorly on learning and memory tasks, while adult mice were significantly more resilient after losing sleep.

Changes At The Level Of Brain Synapses

The results showed that sleep deprivation in young mice significantly altered the formation of synapses. These changes were not seen in adult mice. “This now provides one of the largest and most comprehensive datasets to examine the molecular effects of sleep loss across the lifespan,” Diering said.

Potential Future Treatments

“Development is not something that one can go back and do again,” Diering said. “Sleep is important for the entire life and especially during development. Understanding what we know now will place greater emphasis on understanding sleep issues in ASD and could lead to an important therapeutic avenue to treat ASD and other developmental conditions.”

The findings highlight an important message for parents and caregivers. During early childhood, healthy sleep patterns may play a critical role in shaping the brain for years to come.

Using amphetamines, cocaine and cannabis can significantly increase your risk of having a brain stroke particularly among younger adults, according to a new University of Cambridge analysis

The findings highlight how recreational drug use may contribute to a preventable health risk, especially among people under the age of 55.

Megan Ritson, a stroke genetics researcher at the University of Cambridge and lead author said the results provide strong evidence linking certain drugs to stroke risk.

“These findings provide compelling evidence that drugs like cocaine, amphetamines, and cannabis are causal risk factors for stroke,” Ritson noted.

A stroke occurs when blood flow to part of the brain is interrupted. This can happen when a blood vessel becomes blocked by a clot, known as an ischemic stroke, or when a blood vessel bursts and causes bleeding in the brain, known as a hemorrhagic stroke. Both types can lead to serious brain damage and can be life threatening.

Amphetamines Associated With The Highest Risk

When researchers combined data from eight previous studies, they found that recreational amphetamine use was associated with more than double the risk of stroke across all adult age groups. For individuals under the age of 55, the increase was even greater. In this group, amphetamine use was linked to nearly triple the risk of stroke compared with people who do not use the drug.

Across all age groups, the analysis found that amphetamine use increased the risk of ischemic stroke by 137 percent and hemorrhagic stroke by 183 percent. These figures reflect relative risk, meaning the probability of stroke is higher among users compared with non users.

Cocaine Shows A Similar Pattern

The analysis showed that cocaine use nearly doubled the risk of stroke of any kind and more than doubled the risk of hemorrhagic stroke. Additional genetic investigations were conducted alongside the main analysis to better understand whether the relationship might be causal rather than simply linked to other lifestyle factors.

Eric Harshfield, a genetic epidemiologist at the University of Cambridge, said the findings suggest the drugs themselves may play a direct role. “Our analysis suggests that it is these drugs themselves that increase the risk of stroke, not just other lifestyle factors among users,” Harshfield said.

Cannabis Linked To Smaller But Significant Risk

Among people under the age of 55, cannabis use was linked to a 14 percent increase in stroke risk. Although the increase is lower than that associated with stimulant drugs, researchers say it remains important because cannabis is widely used.

Opioids Showed No Clear Association

A Preventable Health Risk

The researchers also note that many of the studies included in the analysis relied on participants reporting their own drug use. Because of this, other lifestyle factors could potentially influence the results. Further research will be needed to better understand the biological mechanisms involved and how different patterns of drug use may affect stroke risk. Still, scientists say the evidence now available provides an important foundation for future public health strategies.

“These findings give us stronger evidence to guide future research and public health strategies,” Ritson said.
