A recent study suggests that daily cocoa extract supplements, rich in flavanols, may play a significant role in reducing age-related inflammation, a process known as "inflammaging." This inflammation is linked to various chronic conditions, including heart disease and type 2 diabetes. The findings indicate a potential pathway for slowing down aging processes and protecting cardiovascular health.
Key Takeaways
- Cocoa extract supplements may help reduce inflammation and lower the risk of heart disease.
- Flavanols, found in cocoa beans, are believed to be responsible for these heart-health benefits.
- While beneficial, obtaining flavanols through whole foods is generally recommended.
Study Uncovers Anti-Inflammatory Effects of Cocoa Extract
The research, published in the journal Age and Ageing as part of the Cocoa Supplement and Multivitamin Outcomes Study (COSMOS), examined five markers of inflammaging in nearly 600 older adults over two years. A key finding was the significant reduction in high-sensitivity C-reactive protein (hsCRP), a marker associated with increased risk of chronic diseases, among those taking cocoa extract supplements. hsCRP levels dropped by approximately 8% annually in the supplement group compared to a placebo.
These results build upon earlier COSMOS findings involving over 21,000 participants, which indicated a 27% decrease in cardiovascular death and fewer major cardiovascular events in those who took cocoa extract supplements. Researchers believe the anti-inflammatory properties of cocoa flavanols may explain these observed cardiovascular benefits.
The Power of Flavanols
Cocoa extracts used in the study were specifically chosen for their high content of cocoa flavanols. These plant-based polyphenols act as antioxidants, neutralizing harmful free radicals in the body and thereby reducing inflammation. "We know the cocoa bean contains bioactives, flavanols, to improve cardiovascular health through improvements in hsCRP for inflammation and other vascular mechanisms," stated Howard D. Sesso, ScD, MPH, a study co-author and associate professor at Brigham and Women’s Hospital.
Should You Reach for Chocolate?
While the study highlights the benefits of cocoa flavanols, experts caution against simply increasing chocolate consumption. The processing involved in making chocolate bars often reduces flavanol content. Furthermore, the added sugars, saturated fats, and calories in many chocolate products could counteract any potential health advantages. "The study’s result doesn’t imply ‘eat more chocolate’—it implies that a purified cocoa flavanol extract, in controlled dose, may have health benefits," explained Lauri Wright, PhD, RDN, director of nutrition programs at USF College of Public Health. Achieving the flavanol dosage used in the study through dark chocolate alone can be challenging.
Considering Cocoa Extract Supplements
For individuals considering cocoa extract supplements, prioritizing whole-food sources of flavanols, such as dark chocolate with minimal processing, berries, tea, and grapes, is advised. These foods offer a broader spectrum of nutrients and fiber. The effectiveness of flavanols is also likely influenced by overall dietary patterns and lifestyle factors. While the findings are promising, experts emphasize that a modest reduction in one marker is a signal, not definitive proof of disease prevention.
