Discover how dark chocolate might be a sweet way to reduce your risk of type 2 diabetes.
At a Glance
- Harvard study indicates dark chocolate may lower type 2 diabetes (T2D) risk by 21%
- Five servings of chocolate weekly linked to a 10% reduced T2D risk
- Milk chocolate associated with long-term weight gain, not T2D risk reduction
- Study data was drawn from over 30 years and 192,000 participants
The Study and Its Findings
A recent Harvard study found consuming dark chocolate could reduce the risk of type 2 diabetes by 21%. The research revealed that individuals who consumed at least five servings of chocolate weekly experienced a 10% lower risk, with dark chocolate being more effective than milk chocolate. The study data is based on a large pool of 192,000 participants from the Nurses’ Health Studies I and II, as well as the Health Professionals Follow-up Study over more than 30 years.
Dark chocolate’s benefits are attributed to its high levels of cocoa and polyphenols, ingredients known for enhancing insulin sensitivity and lowering oxidative stress. Research suggests these compounds may counteract the negative effects of saturated fats and sugars commonly found in chocolates.

Distinguishing Dark from Milk Chocolate
Researchers emphasized the health advantages of choosing dark chocolate over milk chocolate. While dark chocolate demonstrated a positive impact on diabetes risk, milk chocolate consumption showed a tendency toward weight gain and didn’t correspond with a reduced diabetes risk. Binkai Liu emphasized, “For anyone who loves chocolate, this is a reminder that making small choices, like choosing dark chocolate over milk chocolate, can make a positive difference to their health.”
The findings also highlighted that while moderate dark chocolate consumption can be beneficial, overindulgence might negate these advantages. Thus, moderation is recommended.
Impact on Long-Term Health
This study supports existing research on cocoa’s beneficial characteristics, including its role in combating insulin resistance, oxidative stress, and inflammation. As Qi Sun pointed out, “We were surprised by the clear split between dark and milk chocolate’s impact on diabetes risk and long-term weight management.” Such insights suggest that simple dietary choices can significantly impact diabetes prevention strategies.
The study was published in The BMJ on Dec 5th and was funded by the National Institutes of Health, underscoring the importance of ongoing research into dietary effects on chronic disease prevention. As a part of a broader health regimen involving balanced diet, regular exercise, and lifestyle modifications, dark chocolate could be a beneficial component.
