Is Alcohol Ultimately Dangerous? Latest Insights on Its Effects on the Heart and Cancer

An article from the New York Times dated December 16, 2025, spread on social media, igniting a debate over a particular sentence: the idea that "light drinking is good for the heart" has been "debunked" by research, with the warning that "alcohol causes cancer" weighing more heavily.Facebook

However, at the same time, the discussion that "a small amount may have no harm or even potential benefits for cardiovascular health" resurfaced, causing public perception to waver once again.professional.heart.org

From here, since the full text of the NYT article cannot be referenced due to automatic retrieval limitations, we will "reconstruct" the discussion points based on the summary shared on NYT's official social media and similar topics covered by public institutions, academic statements, and major media analyses. In conclusion, it is not a binary choice of "poison or medicine" regarding alcohol, but rather a discussion of **"which risks to accept, at what probability, and to what extent."**

1) What has "reignited" the debate: The "weak hope" regarding the heart and the remaining significant gaps

The complexity of cardiovascular discussions arises because academic societies have not definitively stated that "a small amount is good for health," while also not being able to completely deny it.

In a scientific statement from June 2025, the American Heart Association (AHA) stated that

• heavy drinking (generally more than two drinks a day) and binge drinking are consistently harmful (leading to high blood pressure, coronary artery disease, stroke, arrhythmia, cardiomyopathy, heart failure, etc.)

• However,there remains a knowledge gap regarding the "true impact" of light to moderate drinking, necessitating high-quality RCTs (randomized controlled trials).

• Currently, it is unclear whether "light to moderate drinking is part of a healthy lifestyle," and the basics such as exercise, smoking cessation, and maintaining a healthy weight should be prioritized.

Further analysis suggests that this AHA document is not a "guideline mandate"

but aims to provide clinicians with materials to explain the "risk ladder" to patients amid persistent popular misconceptions.tctmd.com

In other words, regarding the heart,
"there might be a benefit from a small amount," but the evidence is weak and varies too much from person to person,
leading to the most ambiguous situation.

2) How the "small amount is good for the heart" myth was created and debunked: The pitfalls of observational studies

The famous graph showing that "light drinking is associated with lower mortality" (the so-called J-curve) has been discussed for a long time. However, in recent years, the weaknesses at its root have been repeatedly pointed out.

A representative issue is the inclusion of "sick quitters" among "non-drinkers," those who used to drink but stopped due to illness. This can statistically make "non-drinkers appear unhealthy," resulting in "light drinking appearing healthy." A Stanford analysis explains that such classification distortions can cause "moderate drinking to appear beneficial."Stanford Report

The World Heart Federation (WHF) policy brief also highlights the limitations of observational studies,

• noting that reasons for non-drinking (religious, cultural, health-related) can confound results.

• There are studies involving industry funding.

• No study has confirmed health benefits through RCTs.
  The brief strongly states that the commonly believed message that "alcohol is good for the heart" was a myth.World Heart Federation

On the other hand, Harvard-affiliated researchers have a more "reserved" view. They argue that WHO's assertion that "the safe amount is zero" oversimplifies the current knowledge, stating that "a precise answer is still needed for small amounts," and offer practical advice to adhere to U.S. dietary guidelines (up to two drinks for men and one for women).Harvard Magazine

The key point here is that "the myth has been debunked" does not equate to "a small amount is inherently bad." However, there is not enough certainty to say it is "good." Hence, the debate continues.

3) However, the discussion on cancer is different: WHO and the U.S. Surgeon General say it's a "cause"

While the heart remains a gray area, cancer is much closer to black—this asymmetry makes the discussion even more challenging.

WHO Europe states that there is "no safe level" of alcohol consumption, classifying alcohol as aGroup 1 carcinogen by IARC, explaining that it causes at least several types of cancer (including colorectal and breast cancer). Furthermore, they assert that no threshold can be shown for when the carcinogenic effect is "turned on," and there is no research showing that cardiovascular benefits outweigh cancer risks even with light to moderate drinking.World Health Organization

In the U.S., the Surgeon General's advisory from the Department of Health and Human Services (HHS) outlines the causal relationship between alcohol consumption andat least seven types of cancer (including breast, colorectal, esophageal, laryngeal, liver, oral, and pharyngeal cancer), encouraging awareness and countermeasures.hhs.gov

The National Cancer Institute (NCI) fact sheet also provides sufficient evidence for IARC's Group 1 classification and its impact on oral, pharyngeal, laryngeal, esophageal, and liver cancers.cancer.gov

In summary, the notion of "drinking for health" is hard to justify from the cancer perspective. This is why WHO uses strong language.

4) So what should we base our decisions on? First, align "amount" and "drinking habits" with reality

The main reason this topic stirs up social media is that most people tend to underestimate their "one drink." The U.S. standard drink contains about 14 grams of pure alcohol, with a guideline of 12 ounces (about 355 ml) of beer, 5 ounces (about 148 ml) of wine, or 1.5 ounces (about 44 ml) of distilled spirits.niaaa.nih.gov

However, in reality, drinks at bars or home often exceed this standard easily. Mixed drinks or large glasses can add up more than perceived.

Moreover, recent U.S. government reviews covered in the media suggest that "risks begin at low consumption levels," and in some conditions, "exceeding seven drinks a week increases the mortality risk by 1/1000," offering quite specific numerical models.STAT

More important than the accuracy of these numbers is the understanding that risks increase in a stepwise manner, rather than being a matter of "all or nothing." The AHA's emphasis on understanding "risk levels" is crucial here.tctmd.com

5) Social media reactions: The most common are "confusion," "distrust," and "personal history"

The reactions to this topic on social media are very "human."

① "Another convenient study?" Voices questioning the distance from industry
On Threads, posts sarcastically asking if the NYT article was written by a brewery CEO, or outright declaring "it's bought/it's driven by money" are prominent.Threads

The background for such suspicions includes a history of alcohol research being embroiled in industry funding issues (as noted in a Harvard article regarding NIH research controversies), leaving distrust as a "memory."Harvard Magazine

② "Doctors have always said it's 'poison'" Voices driven by experiential rules
On Threads, there are also assertive statements like "doctors have always said 'alcohol is poison'" (life experience outweighs scientific details).Threads

③ Cancer survivor communities are more earnest and practical
In Reddit's breast cancer communities, discussions revolve around decisions to quit or reduce drinking as a lifestyle choice, with comments like "I stopped after diagnosis" and "recent studies made me believe there's no safe amount."Reddit

This difference in tone strengthens the sentiment that "drinking for health is not the way."

④ Ultimately, "what should I believe?" remains
As Stanford points out, differences in study design (biases in observational studies) and outcomes (heart disease vs. cancer, accidents, etc.) create confusion, making it appear to the general public that "conclusions keep changing."Stanford Report
