Tim Stockwell：关于酒精对健康益处的研究存在夸大甚至错误，许多研究存在利益冲突或方法学缺陷，导致结果夸大了适度饮酒的益处，而忽略了酒精对健康造成的多种危害，包括增加多种癌症、中风、肝病等风险，以及缩短预期寿命。他认为，即使是适度饮酒，也会增加患病和死亡的风险，并且长期饮酒会对人体组织造成损伤，导致DNA复制失败，从而增加癌症风险。他呼吁公众关注酒精的真实风险，并支持实施更严格的酒精监管政策，例如最低单位定价和警示标签。他还提到，疫情期间酒精消费量增加，与COVID-19感染人数增加之间存在关联。 Paul Rand：作为主持人，Paul Rand 更多地是引导访谈，提出问题，并对 Tim Stockwell 的观点进行总结和补充。他表达了对酒精危害的担忧，并就公众对酒精益处的误解、研究方法的缺陷以及酒精监管政策的必要性等问题与 Tim Stockwell 展开了深入探讨。他还提到了公众对酒精危害认知的转变以及“清醒的好奇心”的兴起。 Paul Rand: 作为访谈节目的主持人，Paul Rand 主要负责引导访谈的进行，提出问题，并对 Tim Stockwell 的观点进行总结和补充。他表达了对酒精危害的担忧，并就公众对酒精益处的误解、研究方法的缺陷以及酒精监管政策的必要性等问题与 Tim Stockwell 展开了深入探讨。他还提到了公众对酒精危害认知的转变以及“清醒的好奇心”的兴起。

Key Insights

Why did the research on alcohol's health benefits appear misleading?

Studies often compared moderate drinkers to abstainers, who were systematically less healthy due to factors like lower income, poorer access to healthcare, and poorer diets. This skewed the results to make moderate drinking appear healthier.

What is the J-shaped curve in alcohol studies?

The J-shaped curve describes the relationship between alcohol consumption and risk of premature death. Moderate drinkers appear to have a lower risk than abstainers, but this is likely due to confounding factors rather than alcohol's benefits.

How does alcohol consumption affect life expectancy?

Even moderate drinking reduces life expectancy. For example, six drinks a week can reduce life expectancy by 11 weeks for the average person.

What are the cancer risks associated with alcohol consumption?

Alcohol is linked to multiple cancers, including mouth, throat, esophagus, stomach, colon, rectum, and breast. For instance, about 15% of breast cancer deaths in the U.S. are attributable to alcohol.

How does alcohol cause cancer?

Alcohol is metabolized into acetaldehyde, which damages DNA and can lead to mutations that cause cancer. This process occurs with even moderate drinking over a lifetime.

What is minimum unit pricing, and why is it effective?

Minimum unit pricing sets a floor price per unit of alcohol, regardless of brand or type. It targets cheap, high-alcohol products favored by heavy drinkers, reducing consumption and related harms.

What impact did COVID-19 have on alcohol consumption?

During the pandemic, alcohol was declared an essential commodity, leading to increased availability and consumption. There was a direct link between higher alcohol sales and increased COVID-19 infections.

Why are young adults drinking less today?

Young adults are drinking less globally, possibly due to the rise of social media, increased health consciousness, and a shift in how they socialize and form relationships.

What is sober curiosity, and why is it growing?

Sober curiosity is the trend of questioning the necessity of alcohol in social situations and exploring alcohol-free alternatives. It's driven by health awareness and a desire for clearer minds and longer lives.

How do warning labels on alcohol impact public perception?

Warning labels, especially those highlighting alcohol's cancer risks, can increase public awareness and support for stricter alcohol policies. In some cases, they've doubled support for measures like minimum unit pricing.

Shownotes Transcript

We have long heard the claims that a glass of red wine is good for your heart, but it turns out that the research that fueled this wisdom was actually skewed. Some studies made it appear like moderate drinkers were healthier than people who didn't drink at all, leading the public to believe that alcohol was healthier than it is. While drinking alcohol occasionally might not have catastrophic effects on your health, the data shows that even moderate drinking will reduce your life expectancy.

In this episode, we speak with Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research and a professor of psychology at the University of Victoria. Stockwell has reviewed hundreds of studies that he claims embellished alcohol's effects, and he explains how the new science of drinking is changing the public perception of alcohol. Today, trends like sober-curiosity and “Dry January” are on the rise, and some countries around the world are even implementing new policies around alcohol regulation.
