Can drinking be beneficial for heart health?

New research suggests that the relationship between alcohol consumption and cardiovascular health is much more complex than previously thought. A recent study conducted by biostatistics experts from Boston University's School of Public Health analyzed the impact of alcohol consumption on metabolites, small molecules produced through metabolic processes. The researchers found that the metabolic traces left behind by alcohol consumption were often linked to higher cardiovascular risks. However, they also identified some metabolites that were associated with a lower risk of cardiovascular disease.

The study, published in BMC Medicine, used data from 2,428 individuals who underwent multiple in-person health examinations over a period of 20 years. Conducting thorough studies on the health risks of alcohol consumption is challenging due to the lack of randomized controlled trials in this area. Instead, researchers must rely on observational data or self-reported information from study participants, which may be influenced by biases or underreporting.

Chunyu Liu, one of the study's lead authors and a biostatistics professor at Boston University, emphasized that the effects of alcohol consumption on different molecules and biological processes are complex. Factors such as economic status, food consumption during drinking, the type of alcohol consumed, and the quantity consumed can all have mixed effects.

While the study itself presented mixed messages, Liu suggested that the overall body of literature sends a clear message: individuals who do not currently drink should not start, and those who do drink should stick to moderate levels. This sentiment was echoed by Deepak Bhatt, a top cardiovascular health expert from Mount Sinai Hospital in New York City. Bhatt emphasized that alcohol is generally detrimental to health and cautioned against placing too much emphasis on catchy headlines that suggest potential benefits for alcohol enthusiasts.

In conclusion, the relationship between alcohol consumption and cardiovascular health is complex and still not fully understood. While some metabolites associated with alcohol consumption may increase the risk of cardiovascular disease, others may have a protective effect. Therefore, it is recommended that individuals who currently do not drink should not start, and those who do drink should do so in moderation. It is important to note that the evidence supporting a "sweet spot" for alcohol consumption and heart health is weak.
