Dinh Bac drank one beer: A small matter blown out of proportion, yet science shows it's not worth the noise

During Tet this year, a photo spread across social media: Dinh Bac, a rising star of Vietnamese football, sitting among friends with a beer can on the table. Within hours, hundreds of articles ran with headlines like "player drinks beer," "unprofessional," "affects the national team's image." The public uproar was immediate, with many calling for severe punishment, even exclusion from the national team. But does science condemn such a mundane act so harshly? And why does a single ordinary action become the centerpiece of an entire footballing nation?

The incident occurred during the Tet holiday, when most leagues were on break. Dinh Bac is not the first player to be caught drinking beer during this period, nor will he be the last. But because he is a "prominent star," expected to "set an example," he became the focal point of a debate far beyond one beer. So what is the real issue here? Does one beer have the power to determine the future of a young talent, or is it merely a symptom of a deeper cultural disease in Vietnamese football management?

This article does not aim to defend or condemn Dinh Bac, but to dig into the layers of data and sports science to show that the story is far simpler than the current hype. As someone who has spent most of my life observing football from a structural and player-development perspective, I believe that when discussing alcohol and sport, we need precision, not emotion.

What does science say about one beer?

First, it must be established that alcohol is not on WADA's prohibited list. Since 2026, alcohol has been removed from the banned substances list because scientists realized its impact is negligible at typical doses for most sports. Previously, alcohol was banned in precision sports like archery, car racing, and karate, but football has never had a strict "zero alcohol" principle as some imagine.

UEFA, the leading football organization in Europe, has published nutritional guidelines for professional players. They do not impose an absolute ban but recommend that alcohol consumption "should be considered in a social and cultural context," and they set a limit: no more than 2 units of alcohol per day for men. One unit is roughly a 330ml can of beer. This means even UEFA, with the strictest standards, acknowledges that one beer at a social gathering is not a sin.

However, what matters is not the absolute number, but the specific dose. A 2026 study published in a sports science journal found that heavy drinking, about 1.5g of alcohol per kilogram of body weight, can reduce muscle protein synthesis by 24% to 37%. To reach this level, a 70kg player would need to consume about 100g of alcohol, equivalent to 5-7 cans of beer. Clearly, one beer during a Tet meal cannot reach that threshold. Even if he drank two beers, the numbers remain far from the study's parameters.

In 2026, a study by Dr. Koichiro Hayashi at Kokugakuin University produced results more relatable to real conditions. The team had male Asian runners perform 45 minutes of downhill running, then one group drank beer while the other drank water. The results showed no significant difference in muscle strength recovery or jumping ability between the two groups within 24 hours. The only difference was a slightly prolonged feeling of muscle soreness in the beer group, but at a mild level. For a player on holiday, not training or competing during that period, the impact of one beer is almost negligible.

So why do we still hear calls for bans, severe punishments, or warnings about "professionalism"? The reason may lie in another concern, not purely physiological.

Sleep - the overlooked puzzle piece

Modern sports science has shown that sleep is one of the most important pillars of recovery. Without quality sleep, the body cannot regenerate energy, repair micro-damage, or allow the brain to process tactical information. And here, alcohol has a negative impact even at low doses.

Numerous meta-analyses and studies in sports medicine journals show that alcohol, even one drink before bed, can reduce REM sleep - the deep sleep phase that helps the brain recover and consolidate memory. Fragmented sleep, waking during the night, and feeling inexplicably tired the next morning - these are what one beer can cause. For a player entering a high-intensity training period, losing a few minutes of REM can accumulate into a significant recovery deficit after 48-72 hours.

But look at the context: Dinh Bac drank beer during Tet, not within the competition schedule. If he had a poor night's sleep, he can compensate by napping the next day. The problem becomes serious only when drinking is repeated regularly or becomes a habit before training sessions. That is when sleep - and recovery - are subtly compromised.

In other words, the real risk is not in an isolated incident, but in the cumulative chain. One beer does not ruin a career, but if there's a beer every weekend, or a session every holiday, the body does not have enough time to recover. Vietnamese players, according to many assessments, often decline rapidly approaching age 30. This is not coincidental. It may be the result of a lifestyle lacking discipline in nutrition and recovery, accumulating over many years.

The culture of alcohol in Vietnamese football

The issue is not just about Dinh Bac. The beer story is just the tip of the iceberg. In a recent interview, an anonymous sports doctor in Vietnamese football said: "Occasionally drinking beer is fine, but if a famous star says drinking one or two beers is normal, it will create a bad effect." This remark reveals a concern not about physiology, but about image and influence.

Nutrition specialist Dr. Đỗ Thị Ngọc Diệp has also spoken about the "buffet culture" in Vietnamese football: teams let players eat whatever they like, without controlling quality or nutrition. She pointed out that many clubs only focus on nutrition during national team camps or before important matches, leaving players to fend for themselves. This is not an individual player's problem but a systemic flaw.

There is no standardized process for managing players' nutrition and recovery at Vietnamese clubs. While UEFA has clear, scientifically grounded guidelines, and top European clubs have dedicated nutritionist teams, in Vietnam this is largely left to each player's individual awareness. Consequently, when a player like Dinh Bac slips up and is caught drinking a beer, he is branded unprofessional, but in reality, it is the absence of a proper support system that is to blame.

Is comparing with Ronaldo and Messi fair?

Many fans often use Ronaldo and Messi as role models to demand that Vietnamese players practice extreme discipline. Ronaldo is famous for his strict diet, never touching alcohol. Messi transformed his eating habits after a series of injuries. But these are two of the greatest players in history, with world-class science and training facilities. Using them as a benchmark for a young Vietnamese player in a footballing nation with modest sports science infrastructure is an injustice.

Moreover, even Ronaldo and Messi have had moments of relaxation. Messi has been known to enjoy a beer at parties. What makes them elite is not perfection, but their ability to maintain focus and hard work throughout their careers. They understand that a few beers on a day off do not kill a career, but chronic lack of control will shorten their playing lifespan.

If we compare the professionalism level between Dinh Bac and Ronaldo, the gap is huge. But that comparison is not useful. Instead of demanding Vietnamese players be like European superstars, we should ask: have we equipped them with enough knowledge, habits, and environment to emulate such standards?

We need systemic reform, not individual punishment

Ultimately, the beer story of Dinh Bac should be seen as a wake-up call for Vietnamese football, not an opportunity to punish a young player. We need clear regulations, nutrition education programs, and management mechanisms based on scientific data, rather than on emotion and fear of public opinion.

UEFA did this long ago. They do not ban players from drinking beer, but they provide a guideline framework to help players make smart decisions. If Vietnamese football wants sustainable development, we need to build academies that teach not only tactics but also nutrition, sleep hygiene, and life skills. Medical teams and nutritionists should be present at clubs, not just for the national team.

Dinh Bac may have been unwise to allow himself to be photographed in a sensitive situation. But responsibility does not solely lie on his shoulders. Look at the face of the young man in the photo - a young guy still learning to navigate public life, no one has taught him how to manage his personal image or handle the pressure of fame. We rush to judge while forgetting that Vietnamese football still lacks many tools to produce well-rounded players.

I remember a line from my notebook: "A young player is not a polished gem. It's a broken shard still bearing the potter's fingerprint." Dinh Bac is such a shard, being shaped amid pressures and expectations. The potter here is not only himself but also the entire Vietnamese football system.

When the public condemns one beer, we can convict an individual. But when I dig into the sediment of this case, I see a footballing nation struggling to find a professional identity. We must change management practices, invest in sports science, and educate players from a young age. Otherwise, after Dinh Bac, another young player will be caught drinking beer, and we will conduct another online witch-hunt.

Vietnamese football needs a structural excavation, not to find a culprit, but to rebuild long-term foundations. Let's give young players the chance to be educated, supported, and guided. And remember, one beer during Tet does not determine the future of a person, let alone the future of an entire footballing nation.

As I once wrote: "At age 60, I learned that data only reaches the stadium gate. Inside, people play with fear and dreams." Dinh Bac's beer is a fear, but his dream still lies ahead. Let him live with that dream, and let us together build a healthier playing field where young talents can grow not only technically but also in character and longevity.
