Alcohol and heart health have always had a complicated relationship. While some studies in the past have suggested that moderate drinking might be good for your heart, more recent research is challenging this idea.
A new study has added another layer to this debate by examining the effects of alcohol on the body at a molecular level.
The research, published in BMC Medicine, took a deep dive into how alcohol affects our body’s metabolites. Metabolites are molecules that are created when our body processes substances like alcohol. They can tell us a lot about our health and are used to study various diseases.
The researchers found 60 different metabolites related to alcohol consumption. Surprisingly, these metabolites seemed to have mixed effects on the risk of cardiovascular disease (CVD), which includes heart attacks and strokes.
They identified seven metabolites linked to a higher risk of CVD from moderate drinking. But at the same time, they found three other metabolites that were linked to a lower risk of CVD from the same level of drinking.
This discovery is important because it shows that the effects of alcohol on heart health aren’t straightforward. Alcohol can cause changes in our bodies that might be both good and bad for our hearts.
This research helps us understand the complex ways in which long-term drinking affects our heart health.
Chunyu Liu from Boston University and Jiantao Ma from Tufts University, who led the study, emphasize that their findings are particularly relevant because most of their study participants were moderate drinkers.
This means the research sheds light on a common pattern of alcohol consumption and its impact on heart health.
To get these results, the team studied blood samples from 2,428 participants in the Framingham Heart Study Offspring Study.
They looked at the link between drinking beer, wine, and liquor over 20 years and the levels of 211 metabolites in the blood. Among these participants, 636 developed heart disease during the study.
One interesting finding was that alcohol affected men and women differently. Thirteen of the 60 alcohol-related metabolites were more strongly associated with alcohol consumption in women than in men.
This could be because women typically have smaller bodies and might end up with higher blood alcohol levels after drinking the same amount as men.
The type of alcohol consumed also made a difference. Beer, wine, and liquor each had a unique impact on metabolites. Generally, beer had a slightly weaker association with these metabolites compared to wine and liquor.
Despite these intriguing findings, the researchers caution that more work is needed.
In conclusion, this study doesn’t settle the debate about alcohol and heart health. Instead, it highlights the complex and sometimes contradictory ways in which alcohol affects our cardiovascular system.
It opens up new paths for future research and underscores the importance of considering individual responses to alcohol when discussing heart health.
