As people worldwide toast to the New Year, new research sheds light on the potential health benefits of moderate wine consumption — offering food for thought for those enjoying a celebratory glass. A recent multicenter study, led by the University of Barcelona and published in the European Heart Journal, suggests that drinking wine in moderation may reduce the risk of cardiovascular complications, though experts caution that more research is needed to solidify these findings.

Study Highlights: Wine and Cardiovascular Health

The study analyzed 1,232 participants in the PREDIMED project, a significant epidemiological study investigating the Mediterranean diet’s impact on heart health. Researchers used tartaric acid, a biomarker unique to grapes and wine, to objectively measure wine consumption — marking a departure from traditional reliance on self-reported data, which is prone to inaccuracies.

Results indicated that light wine consumption (one glass per week to less than half a glass per day) was associated with a 38% reduction in cardiovascular complications, while moderate consumption (half a glass to one glass per day) lowered the risk by up to 50%. However, these benefits disappeared when consumption exceeded one glass daily. Researchers emphasized that moderate wine consumption should always accompany meals, aligning with Mediterranean dietary practices.

The study adds to the ongoing debate surrounding alcohol’s role in health. While excessive alcohol consumption is unequivocally harmful, the effects of moderate wine consumption remain contentious. Some studies highlight protective cardiovascular benefits, while others find no significant effects. Lead researcher Ramon Estruch noted that conflicting results often stem from unreliable consumption records, a challenge this study sought to address through biomarker validation.

Despite the promising findings, experts, including co-author Inés Domínguez, urge caution. “The observational nature of the study limits our ability to establish causality,” she stated. The researchers highlighted two paths for future investigation: randomized nutritional intervention studies and mechanistic studies exploring wine’s anti-inflammatory compounds, such as resveratrol. However, randomized studies are resource-intensive, and results may take years to materialize.

A Balanced Perspective

While this study supports moderate wine consumption as a potential heart-healthy choice within the context of the Mediterranean diet, it underscores the need for further research. The findings offer a nuanced perspective for health-conscious individuals looking to embrace both tradition and science in the New Year.

As 2024 ends and 2025 begins, experts advise moderation and mindfulness — whether raising a glass or considering the broader implications of dietary choices. For now, the relationship between wine and heart health remains a topic of careful consideration, ripe for further exploration between health coaches and clients.

New research from the University of Sydney, published in the British Journal of Sports Medicine, suggests that just four minutes of vigorous incidental physical activity a day could nearly halve the risk of major cardiovascular events in middle-aged women who do not engage in structured exercise.

The study analyzed data from 22,368 non-regular exercisers (13,018 women and 9,350 men) aged 40–79 who wore physical activity trackers for nearly 24 hours a day, seven days a week, between 2013 and 2015. Cardiovascular health was monitored through hospital and mortality records, tracking major adverse cardiovascular events (MACE) such as heart attack, stroke, and heart failure until November 2022.

The findings revealed that after adjusting for factors such as lifestyle, co-existing conditions, cardiovascular health and ethnicity, vigorous intermittent lifestyle physical activity (VILPA)—defined as brief bursts of intense activity embedded in daily life—lowered the risk of major cardiovascular events in women, with greater VILPA correlating to a lower risk.

Women who averaged 3.4 minutes of daily VILPA were 45% less likely to experience a major cardiovascular event, 51% less likely to have a heart attack and 367% less likely to develop heart failure compared to women who did not engage in VILPA.

Although the researchers suggest further testing is needed to understand how VILPA can positively impact cardiovascular health, lead author Professor Emmanuel Stamatakis emphasized that, like most health-improving measures, commitment is key. He also indicated that the findings present an activity target for women who are unable or unwilling to engage in traditional exercise.

“Importantly, the beneficial associations we observed were in women who committed to short bursts of VILPA almost daily,” Prof. Stamatakis said. “This highlights the importance of habit formation, which is not always easy. VILPA should not be seen as a quick fix—there are no magic bullets for health. But our results show that even a little bit higher intensity activity can help and might be just the thing to help people develop a regular physical activity – or even exercise – habit.”

He added that as a starting point, short bursts of activity could be as simple as a few minutes of stair climbing, uphill walking, power walking or playing tag with a child or pet.

Interestingly, men were found to experience fewer benefits than women from brief bursts of VILPA. Men who averaged 5.36 minutes of daily VILPA were only 16% less likely to experience a major cardiovascular event compared to those who did not engage in any VILPA.

The research could help influence health coaches and fitness trainers who have middle-aged women as clients and are perhaps more reluctant or unable to engage in high-intensity interval training (HIIT). VILPA could potentially do more than lower cardiovascular events — other research (also led by Prof. Stamatakis) suggests it may lower cancer risk.

While HIIT remains a popular fitness method, low-impact modalities are on an upswing, according to ClassPass. The booking platform just released its Annual Look Back report, which noted low-impact training saw a notable increase in reservations (109%), demonstrating an interest in more accessible fitness options.
