A long-term study from Harvard University indicates that consuming dark chocolate might be associated with a lower risk of developing Type 2 diabetes compared to milk chocolate. The findings suggest that flavonoids in cocoa could play a role, though the evidence does not confirm causation. The study analyzed data from over 192,000 participants and found those consuming more than five servings of dark chocolate weekly had approximately 20% reduced diabetes risk. Experts urge caution, emphasizing that chocolate should still be eaten in moderation due to its high calorie, sugar, and fat content.
