The COSMOS (Cocoa Supplement and Multivitamin Outcomes Study) has recently brought to light intriguing findings regarding cocoa extract and its potential impact on cognitive health in older adults, particularly those with a lower quality diet. This significant research, a collaborative effort by specialists from Brigham and Women’s Hospital and Harvard Medical School, was detailed in The American Journal of Clinical Nutrition, offering new perspectives on the role of dietary supplements in cognitive wellness.

Exploring the Cocoa Extract Study: Composition and Participants
This study, delving into the health impacts of cocoa extract, involved a diverse group of 573 individuals, most of whom were around 70 years old, with a female representation of nearly half. Interestingly, before the study commenced, approximately 11% of these participants were regular chocolate consumers. The primary focus of the research centered on understanding the effects of daily cocoa extract supplementation. Each participant received a specific dose – 500 milligrams of cocoa flavanols daily, which included 80 milligrams of epicatechin. These flavanols, naturally occurring in cocoa products, teas, and a variety of fruits, are recognized for their potential health benefits.
Selective Cognitive Enhancements Noted in Cocoa Extract Study
The research yielded nuanced and specific outcomes regarding cognitive improvements:
Targeted Cognitive Enhancement: The study revealed that cognitive function enhancements were primarily observed in a subset of participants – those who began the study with a lower-quality diet. Contrarily, individuals who were already adhering to a healthy diet did not report similar cognitive benefits.
Boost in Executive Function for Some: Notably, among those with lesser dietary quality, the intake of daily cocoa supplements was correlated with significant improvements in overall cognitive abilities and executive function. Executive function, crucial for effective behavior management and self-control, appeared to be positively influenced by cocoa extract in this particular group.
Diverse Outcomes in Cocoa Extract Research
This study’s outcomes present a unique perspective when compared to other related research:
Alignment and Divergence with Previous Studies: The observed benefits of flavanols on memory enhancement in older adults, especially those with a lower diet quality, are consistent with previous research findings. However, these results present a contrast when viewed in the context of another segment of the COSMOS study. The latter indicated that a daily multivitamin/mineral regimen could enhance overall cognitive function, yet the cocoa extract did not demonstrate a notable impact in this regard. It is important to note that this particular segment of the COSMOS study did not differentiate the participants based on their dietary quality, which could account for the varying results.
Support and Independence in the Cocoa Extract Study
The research was financially supported by Mars Edge and Pfizer Consumer Healthcare, now known as Haleon. Importantly, while these companies provided funding, they were not involved in the crucial aspects of the study. Specifically, they did not participate in the analysis of the data, the interpretation of the findings, or the preparation of the study’s manuscript, ensuring the research’s independence and objectivity.
Future Directions in Cocoa Extract Research
The implications of this study on cocoa extract supplements and their potential benefits for cognitive function in older adults, particularly those with poorer diets, invite cautious optimism but not definitive recommendations. The research points towards a need for further exploration to fully grasp these findings. Dr. Chirag Vyas, a prominent figure in the study, advocates for the inclusion of diet and nutritional status in upcoming research to more accurately assess the impact of cocoa extract on cognitive health.
Dr. Thomas Holland from RUSH University in Chicago also underscores the study’s distinct focus on specific food compounds, namely flavanols. He draws a parallel with his own research, which delves into the dietary consumption of flavonols, a different class of flavonoids, and their potential association with a lowered risk of Alzheimer’s disease. This comparative perspective emphasizes the nuanced and complex relationship between specific dietary components and cognitive health.
Final Thoughts on the Cocoa Extract Study
This investigation into cocoa flavanols’ impact on cognitive health in older adults opens a new chapter in understanding the relationship between diet and brain health. However, the specific nature of these findings and the necessity for more extensive research mean that cocoa extract supplements are not currently advisable as a preventative measure against cognitive decline. This study serves to highlight the greater significance of individual dietary habits and their role in cognitive health interventions. It suggests a more personalized approach to nutrition, taking into account the unique dietary needs and patterns of each individual, especially in the context of aging and cognitive well-being.
