Eating Dark Chocolate May Reduce Risk of Type 2 Diabetes, Study Suggests
A new study published in The BMJ found that eating dark chocolate may be associated with a reduced risk of developing Type 2 diabetes. The study, which followed over 190,000 participants for up to 34 years, found that those who consumed at least five servings of dark chocolate per week had a 21% lower risk of developing Type 2 diabetes compared to those who consumed less than once a month.
The researchers also found that consuming at least five servings of any type of chocolate per week was linked to a 10% lower risk of developing Type 2 diabetes, but the effect was more pronounced for dark chocolate. The study’s lead investigator, Dr. Qi Sun, noted that the findings do not necessarily mean that dark chocolate is responsible for the reduced risk, but rather that it may be a marker for other lifestyle factors that are beneficial for overall health.
The study’s results build on a broader body of research linking dark chocolate consumption to reduced risks of certain health conditions, including high blood pressure, cardiovascular disease, and insulin resistance. Dr. Sun emphasized that while the findings are encouraging, they should not be taken as a recommendation to overindulge in chocolate.
The study also highlighted the importance of considering other lifestyle factors in addition to diet, such as exercise, alcohol consumption, and smoking, which may have an impact on the risk of developing Type 2 diabetes. Dr. Susan Spratt, a professor of medicine, noted that while dark chocolate may be a part of a healthy diet, it should not be seen as a substitute for a balanced diet and regular exercise.
Experts suggest that the potential benefits of dark chocolate may be due to its high content of fiber and beneficial plant-based compounds called flavonoids, which have antioxidant and anti-inflammatory effects. However, they also acknowledge that more research is needed to fully understand the relationship between dark chocolate and Type 2 diabetes.
In the meantime, health experts recommend choosing dark chocolate with at least 70% cocoa content and consuming it in moderation, about an ounce per day. It is also important to be aware of potential contaminants like lead and cadmium, which have been found in some dark chocolate products. Ultimately, a healthy diet rich in whole grains, vegetables, and lean proteins, combined with regular physical activity and limited added sugars, remains the best way to reduce the risk of Type 2 diabetes.
