Cocoa Extract Shows Promise in Slowing Aging Process Among Older Adults, New Research Reveals

Cocoa extract may offer significant benefits in reducing inflammation within the body, potentially lowering the risk of age-related diseases in older adults. This assertion comes from a substantial new study conducted by scientists at Mass General Brigham in Boston.

Study Overview and Methodology

The research involved nearly 600 participants, averaging 70 years of age, who consumed either 500 milligrams of cocoa extract or a placebo daily for two years. This investigation tracked key health markers to evaluate the effects of cocoa on inflammation.

Key Findings on Inflammation

Those who ingested cocoa compounds experienced an 8.4% slower annual increase in high-sensitivity C-reactive protein, known as hsCRP. This crucial blood marker is widely utilized to gauge systemic inflammation levels. In contrast, participants in the placebo group did not show such improvement.

Published this month in the British journal Age and Ageing, these findings represent a substudy of the Cocoa Supplement and Multivitamin Outcomes Study, commonly referred to as COSMOS. With over 21,000 participants, COSMOS constitutes one of the largest clinical trials focusing on cocoa’s flavanols, which are naturally occurring compounds renowned for their anti-inflammatory properties.

Understanding Inflammation and Aging

Inflammation plays a vital role in the body’s defense against injury and infection, proving beneficial in the short term. However, as people age, inflammation can linger at low levels, a condition termed “inflammaging.” This ongoing inflammation can incrementally harm blood vessels, muscles, bones, and even the brain, contributing to various age-related diseases.

Dr. Howard Sesso, an associate epidemiologist at Brigham and Women’s Hospital and a study author, explained that inflammation is intricately linked to the development of several aging-related diseases, particularly cardiovascular issues.

The Impact on Cardiovascular Health

Previous findings from the COSMOS study indicated that prolonged cocoa flavanol supplementation significantly reduced the rate of cardiovascular disease-related fatalities by 27%. This latest research provides crucial insights into the underlying mechanisms contributing to such improvements.

According to the Centers for Disease Control and Prevention, heart disease remains the leading cause of death in the United States, resulting in one death approximately every 34 seconds due to cardiovascular issues.

The Role of a Healthy Lifestyle

Dr. Yanbin Dong, the senior author of the study and director of Augusta University’s Georgia Prevention Institute, emphasized that while cocoa extract exhibits promising effects, it should not supplant a healthy lifestyle. Instead, it underscores the extract’s potential in modulating inflammation as individuals age.

Dr. Sesso echoed these sentiments, advocating for a diverse and colorful diet rich in flavanols from a variety of plant sources, not solely cocoa. He explained that this approach ensures a comprehensive range of health benefits.

Forms of Cocoa and Their Benefits

Cocoa, the primary ingredient in chocolate, undergoes processing that turns roasted cacao beans into cocoa solids and cocoa butter. Unlike chocolate bars, cocoa capsules provide concentrated doses of flavanols without the added sugars or fats that typically accompany chocolate products. However, processing can diminish the antioxidant properties of chocolate, a factor to consider when consuming cocoa-based products.

Importance of Continued Research

Although the study indicates that cocoa extract can lower hsCRP levels, researchers caution that these findings do not guarantee increased longevity or disease prevention. They highlighted the necessity of more extensive research to draw definitive conclusions.

Mark Kovacs, Ph.D., an exercise physiologist and longevity expert not involved in this study, stated that while lower hsCRP levels are indeed encouraging, the critical health outcomes we scrutinize—such as heart attacks, strokes, and improvements in mobility—have yet to be substantiated.

He further advocated that any dietary or supplemental approaches aimed at targeting inflammation should complement foundational aspects of healthy aging, including regular exercise, adequate sleep, and a nutrient-rich diet like the Mediterranean diet.

Demographics and Future Implications

The current trial primarily involved healthy older adults, predominantly from White backgrounds, raising questions about the generalizability of the results. Researchers express optimism that findings will hold true across more diverse populations, albeit they stress the need for future studies to confirm this.

Sesso remarked on the substantial interest in the scientific community regarding flavanols and their impact on cardiovascular health. He hopes that the new insights from the study will provide vital evidence for understanding the effects of cocoa on aging.

Funding and Affiliated Institutions

The study received funding from the National Institutes of Health, with contributions from Mars Edge and Pfizer in terms of study pills and infrastructure. Researchers disclosed connections to these companies but affirmed that they did not influence the analytical process.

Examining the Path Forward

The findings from this cocoa extract study lay the groundwork for future exploration into the relationship between flavanols and aging processes. As more research unfolds, the prospect of incorporating cocoa into a broader strategy for promoting healthy aging may become a crucial area of focus.
