For the second time in a row, the Beer and Health Initiative offers a Publication Award of €1,000 for the best, most remarkable publication of the year focusing on moderate beer (or alcohol) consumption. Deadline of application is 31 March 2022.
A new meta-analysis finds a decreased risk of Parkinson’s disease with alcohol consumption. The lowest risk is present for people drinking 2,5 to 3,5 drinks a day. Interestingly, only beer is significantly associated with a lower risk, not wine and spirits. Whether the relation is causal is still unclear.
Can alcohol consumption influence erectile disfunction in men? The answer is more complicated than a simple yes or no. Drinking large amounts of alcohol can make it hard to get or keep an erection in that moment. But a recent meta-analysis finds that moderate alcohol consumption is associated with a lower risk of erectile disfunction.
Moderate alcohol consumption is associated with a lower risk of developing cardiovascular disease. But what if you already have cardiovascular disease? A recent meta-analysis still finds a decreased risk of mortality and cardiovascular events for those drinking moderately compared to current non-drinkers. Up to 10 drinks a week might have protective effects and there is no elevated risk with heavy alcohol consumption.
Age-related macular degeneration is a chronic disease of the eyes, and is the leading cause of severe visual loss in adults over the age of 50. A recent meta-analysis finds that moderate and heavy alcohol consumption are associated with the risk to develop early age-related macular degeneration. Late age-related macular degeneration, on the other hand, is not associated with any amount of alcohol.
Recently, two meta-analyses looked into the effect of moderate alcohol consumption in patients with non-alcoholic fatty liver disease (the most prevalent chronic liver disorder). Both studies find a decreased risk of advanced liver fibroses in patients who drink in moderation. The advice from the researchers: patients with steatohepatitis or advanced fibrosis should avoid alcohol, but patients with low fibrosis risk may be allowed to drink moderate amounts of alcohol.
For the first time, a study reviews all mendelian randomization studies on alcohol consumption and cardiovascular disease, diabetes and mortality. The authors conclude that due to a lack of consistency in methodology and results, it is not yet possible to draw conclusions on the causal role of moderate alcohol consumption on cardiometabolic health.
A new systematic review looks at the short and long-term effects of alcohol consumption on the ability of an artery to widen when blood flow increases; also called flow-mediated dilation. This is an important measure because a decrease in this ability can cause cardiovascular problems such as hypertension and coronary artery disease. The authors conclude that light to moderate alcohol consumption may have minimal effects, but heavy alcohol consumption is associated with a decreased flow-mediated dilation.
Based on an umbrella review, which is a review of existing meta-analyses, there is strong or highly suggestive evidence that alcohol consumption is positively associated with risk of postmenopausal breast, colorectal, esophageal, head & neck, and liver cancer.
Alcohol contains a lot of energy. With 7 kcal per gram it is the second most energy dense nutrient after fat (9 kcal per gram). Does that mean drinking alcohol is associated with overweight and obesity? Results are still inconsistent. A recent meta-analysis looks at almost 130 studies and finds different results per study design. Heavy alcohol drinkers have a higher risk of overweight and abdominal obesity than non-alcohol or light drinkers in cross-sectional studies, but this is not the case in cohort studies.
