What studies show about the heart health benefits of moderate drinking
Moderate drinking, defined as up to one drink per day for women and up to two drinks per day for men, has been linked to potential health benefits for the heart [1]. Research suggests that moderate drinkers may have a lower risk of heart disease, heart attacks, and strokes compared to non-drinkers. A meta-analysis of 40 studies found that moderate drinking was associated with a 18-25% reduction in the risk of heart disease [2].
Why does moderate drinking possibly have a heart health benefit?
Several mechanisms may explain the potential heart health benefits of moderate drinking. One theory is that moderate drinking helps to increase levels of high-density lipoprotein (HDL) or "good" cholesterol, which can aid in removing excess cholesterol from the bloodstream [3]. Some studies also suggest that moderate drinking may improve blood flow and lower blood pressure, which can help reduce the strain on the heart [4].
How does moderate drinking compare to abstinence?
While moderate drinking may have heart health benefits, complete abstinence appears to have its own advantages. A study of over 1 million Swedish adults found that drinking 7-14 drinks per week was associated with a reduced risk of heart disease compared to non-drinking, but abstinence was linked to an even lower risk [5]. Therefore, it's essential to weigh individual risks and health considerations before making any changes to one's drinking habits.
Can everyone benefit from moderate drinking, or are there risks to consider?
Unfortunately, not everyone can enjoy the potential heart health benefits of moderate drinking. Excessive drinking, defined as more than two drinks per day for men and one drink per day for women, increases the risk of heart disease, high blood pressure, and other cardiovascular problems [6]. Pregnant women, people with a family history of addiction, and those with certain medical conditions should avoid drinking altogether to minimize potential risks.
When does the patent on potential heart health benefits expire?
There is no patent on the idea that moderate drinking may have heart health benefits. The concept of moderate drinking and its potential effects on cardiovascular health have been extensively studied over several decades.
