Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

  • Researchers used a new MRI technique to precisely measure brain electrical activity.
  • By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
  • Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
  • MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

The human brain is a complex network of billions of neurons that communicate through electrical impulses. Brain conductivity refers to the efficiency with which these electrical signals travel through brain tissue. It's akin to the speed and clarity of a digital signal through a wire. In layman terms, your brain must function in its peak condition as it is essential for various cognitive processes, including memory, attention, decision-making, and motor control.

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

After a long day at work, the occasional glass of wine helps many people unwind. However, some struggle to strike a balance and get involved in binge drinking habits. If you are someone who is unable to give up that frequent dose of cocktails, then a study claims that weight loss drugs can come to your rescue. Experts have found that alcoholics who are obese, when given Wegovy, could curb their drinking habits by as much as 70 per cent. A study in Denmark was led by experts from the Mental Health Centre Copenhagen and Frederiksberg Hospital, and experts used semaglutide on 108 obese patients seeking treatment for alcohol use disorder.

Can weight loss drugs help curb drinking habits?

Half the participants in the study were given 2.4 mg of the drug for six months. The other half were also given a dummy drug. Researchers found that people who were on weight loss drugs had fewer days of binge drinking. Furthermore, their alcohol cravings also dipped compared to people on placebo. Before the trial began, participants engaged in binge drinking on an average of 17 days per month.

Researchers also noted that people who were given semaglutide for six months saw their binge drinking days reduce to five in a 30-day period. This correlated to a 40 per cent dip in drinking days in a month, compared to a 26 per cent dip in the placebo group. These dummy drugs helped reduce drinking days to nine. In terms of alcohol quantity, trial participants drank roughly 2,200 g in the 30 days before the trial started. This meant about 154 drinks in a month, or five per day. Over a period of six months after the trial, there was an impressive 70 per cent dip — from an average of 154 drinks a month to 46 drinks a month in people who were taking semaglutide.

What are the benefits of semaglutide?

Alcohol consumption dipped by an impressive 47 per cent in the dummy drug group as well. The study found that overall alcohol consumption can be reduced among semaglutide users compared to people who were taking the placebo. Researchers found that semaglutide not only affects appetite but also influences biological mechanisms associated with addiction.

Independent researchers found that the results were encouraging and strong enough to be used in helping people struggling with alcohol use problems. However, more research is required in this area. Researchers also noted that there were no follow-ups with the participants after the semaglutide treatment ended. This means that experts could not be fully certain whether people reverted to their old drinking habits once they stopped using the medicine.

What are the health benefits of weight loss drugs?

Apart from inducing weight loss, weight loss drugs have the following health benefits:

  1. Quitting smoking
  2. Can help kick drug habits such as cocaine use
  3. Lower risk of heart attack or stroke
  4. May help reduce blood pressure and cholesterol to improve heart health
  5. Lower risk of dementia

A whopping $600 million global vaccine aid meant for poorer nations has been put on hold by US Health Secretary Robert F. Kennedy Jr., according to a media report.

The delay in vaccines is putting pressure on the international humanitarian group Gavi, the Vaccine Alliance that distributes them, Politico reported.

Gavi noted that it has not received the funds due for the current and previous fiscal years, which account for about 15 percent of its budget.

The funds are set to expire on September 30 if the Trump administration does not release them.

The organization provides vaccines for 20 diseases, including measles, malaria and polio, to more than 50 low-income countries worldwide.

Sania Nishtar, Gavi CEO, told the newswire AFP, the funding gap, combined with reductions from other donors, has particularly impacted malaria vaccination efforts.

Gavi has delivered 39 million doses of a malaria vaccine to 25 African countries, where the disease predominantly affects children under five. Nishtar warned that tens of thousands of children could die as a result of the funding cuts.

Why Is Kennedy Holding Up Vaccines

Kennedy argues that the shots are obsolete with dangerous ingredients that the US has long since phased out.

“Gavi has refused to provide the United States with the specific data, studies, or detailed accounting of how US funds are used,” Emily Hilliard, senior press secretary at the Health and Human Services Department, said in a statement.

Advocates for Gavi, the Vaccine Alliance warn that withholding funds could cost children’s lives. They argue that the vaccines used are safe and better suited for developing regions, where refrigeration is limited and administering booster doses is more difficult.

Hilliard said Gavi has declined to create a plan to phase out thimerosal, a mercury-based vaccine preservative that Kennedy believes may be linked to autism. The administration has asked Gavi to stop using vaccines containing this preservative.

Thimerosal is used in several vaccines distributed by Gavi, including combination shots protecting against multiple diseases, according to former chief executive Seth Berkley. He explained that many developing countries rely on multi-dose vials, which require less refrigeration but may contain thimerosal to prevent contamination.

Without such vaccines, “kids would go without vaccines… and that would lead directly to deaths,” Berkley said.

During testimony before the Senate Appropriations Committee, Kennedy also raised concerns about a vaccine used to protect against diphtheria, tetanus and pertussis, claiming it had been discontinued in the US due to safety issues.

Gavi responded that the vaccine remains in use because it offers longer-lasting protection and requires fewer doses. The organization said the vaccine “is safe and effective and estimated to have saved 40 million lives in the past 50 years,” the report said.

A plant-based diet is highly recommended for a healthy heart — weight watchers can also benefit from it, as can diabetics. When one goes vegan, the biggest change comes when one moves from dairy milk to oat, almond, or soy milk. Parents, too, are now shifting their children to trendy vegan milk options — little do they realise that this could bring their worst fears to life. According to the British Society for Allergy & Clinical Immunology, drinks that are aimed at children and often marketed as healthy are usually loaded with sugar and offer little or no nutrition.

Why has plant milk become a preferred choice?

Experts found that children under five years of age are more prone to malnutrition, tooth decay, or even obesity. The study is the first of its kind, and its warning will be published in the coming week. It is backed by the British Dental Association and the British Dietetic Association. Doctors say that plant-based drinks are often compared to cow’s milk in terms of nutrition. However, these claims are not supported by current evidence.

Why is plant milk discouraged for children?

Plant milk has gained popularity in recent years because of the health benefits that many believe it offers. While adults may benefit from it in several ways, toddlers must not be given these packaged, sugary drinks. The added sugars can become nothing more than a frequent treat for children, who may lose their milk teeth sooner and suffer from decay. Researchers found that families are often convinced that plant milk is good for children, but these oat, almond, and soy versions of milk are processed and full of sucrose and fructose syrups.

According to a report, most of these drinks contain large amounts of sugar in the form of maltodextrin, glucose syrup, sucrose, and fructose. A 350 ml glass of such milk contains more than double a toddler’s daily sugar allowance. Ideally, toddlers should not be given more than 14 grams of sugar every day. Their young bodies can struggle to absorb vitamin B12 and calcium from plant drinks. The BSACI recommends that parents opt for unsweetened, fortified plant milk instead, as these can play a crucial role in supporting children’s health.

How do ultra-processed foods affect children’s health?

Ultra-processed foods (UPFs) are defined as food groups that undergo a great deal of processing — the most natural foods fall under Group 1, while heavily processed foods are placed under Group 4. While these do not definitively determine how healthy a food option is, they indicate the level of processing involved. Highly processed foods are associated with a range of health problems, which is why it is important to make informed dietary choices.

What are minimally processed foods?

In your kitchen, foods with a minimal level of processing include:

  1. Fruits
  2. Vegetables
  3. Grains
  4. Legumes
  5. Meat and poultry
  6. Eggs
  7. Fish and seafood
  8. Fresh milk
  9. Spices and herbs
  10. Coffee and tea
  11. Nuts and seeds
  12. Plain yoghurt

What are ultra-processed foods in your kitchen?
