Cocoa Flavanols

You are here

What are cocoa flavanols and what could they mean for our health?

Cocoa flavanols are naturally occurring dietary compounds that are found in the cacao plant. So why are they relevant for human health? A growing body of research has shown that they can support the function of our blood vessels. Flavanol intake increases nitric oxide which improves blood vessel elasticity and supports cardiovascular health. Working with a network of academic partners, we have spent the past twenty years trying to thoroughly investigate the role that cocoa flavanols can play to support health.

So, is chocolate healthy because of flavanols?

No, chocolate is not a health food. We’re clear that chocolate is a treat and our research into cocoa flavanols is not about promoting chocolate as healthy. Cacao beans are a rich source of flavanols, but chocolate is not the best source for these nutrients, because they are actually destroyed in the chocolate making process.

“We do not study chocolate either in the context of our clinical research programs, and we don’t look at the relationship between chocolate intake and health outcomes”

The research we participate in has two aims. One – to answer comprehensively whether they are good for our health. And two – if they are, to investigate how we can translate these benefits into products that deliver health benefits to consumers, based on scientific evidence.

How do we make sure our research is sound?

When it comes to research, we take our responsibility to produce credible and robust science seriously. We follow well-established methods of scientific best practice and mitigate bias in all the research we are involved with.
When we work with partners, we do not tie our support of research to specific outcomes. We always encourage our research partners to publish studies we’ve collaborated on – whether the outcome is favorable to Mars or not.
The clinical trials we are involved in use matched controls or placebos alongside our test materials. This means that neither the participants nor the scientists know who is receiving the active ingredient. This is critical to addressing the issue of bias. This also enables us to conduct randomized controlled trials, which are widely thought of as the “gold standard” in scientific research.

Now we want to take this research further...

Mars, Incorporated is partnering with scientists at Brigham and Women’s Hospital to thoroughly answer the question of whether flavanols are good for people’s health. The study, COSMOS, is a randomized, double-blinded, and placebo-controlled trial. It’s also the largest clinical trial on flavanols and cardiovascular health.
Our hope is that through continued research we can harness the power of flavanols and potentially develop healthy products that support cardiovascular health.
