It’s probably ⁢too good to be true, but a ⁢recent study published on the British Medical Journalit brings ⁤encouraging news:⁤ Eating dark chocolate is ‌associated ​with a lower risk ‌of developing type 2 diabetes. The research is observational in nature and did not prove that ​chocolate was responsible for⁤ this health benefit (the cause-effect relationship was not ⁤proven); Another thing is that people who also consume‍ dark chocolate may be less likely to develop diabetes (a greater association has been observed among those who follow a healthy diet).

“Dark chocolate should not be considered a ‘magic bullet’ for preventing diabetes,” warns Professor Qi sun,⁢ professor ⁣of‌ epidemiology and ⁤nutrition at‌ the Harvard TH Chan School of Public Health and lead author of the ‍study. “Rather, the findings ⁣suggest that some ​dark chocolate is part of⁢ a healthy diet.”

The ‌results ‌of the study

researchers⁤ began studying three groups of healthcare workers in the mid-1980s. every four years,more than ‍190,000 participants ⁢filled out detailed‍ dietary questionnaires asking how often they consumed chocolate. Starting ⁤in ‌2006,researchers changed the questionnaires they asked participants How often did they ⁢consume dark and milk chocolate?. ‌Study participants were followed‍ for 34 years. During this period, approximately 19,000 ‍participants developed‌ type ‌2 diabetes.

After adjusting the data taking into account other aspects of your⁤ lifestylesuch as exercise,alcohol consumption,smoking,an overall healthy diet,and a family history of diabetes,researchers found that people who consumed at‌ least five servings of‍ any type⁣ of chocolate ⁣per ​week ‍had a 10% lower risk % ⁣of developing type⁣ 2 diabetes compared to those who rarely or never ate chocolate.

The debate: is chocolate good?‍ How much ⁤can you ‍eat ​per day?

When ⁣the researchers further analyzed data⁣ from 112,000 people who⁤ provided details on the types‌ of chocolate they consumed,they ​saw an even‍ more surprising result: Those who consumed at ​least five servings of dark⁣ chocolate per week had a 21 percent lower ⁣risk of developing the type 2 diabetes.⁣ compared to those who consumed dark ‌chocolate less than once a⁤ month.

Los participants who consumed milk⁢ chocolate, As this second analysis showed, the subjects were not protected against type 2 diabetes: rather, they were more likely to gain weight during the study.

limitations of the ⁤study

“Even though the ⁢study is large and well-designed,like all⁣ observational studies,it was unable to⁢ demonstrate a cause-and-effect relationship between dark chocolate consumption and ​the prevention of type 2 diabetes,” said Dr. Dr. Susan at the New York Times, ⁢endocrinologist and nutritionist at Duke University School of Medicine.The study shows an effect of correlation and not causation:‌ “Those⁢ who consume⁢ dark chocolate generally⁣ have a more health-conscious lifestyle”, agrees Stefano erzegovesi, psychiatrist and nutritionist.So it’s possible that the people in the study who ate dark chocolate ⁢were healthier for other⁤ reasons: perhaps they exercised more, ate a healthier‍ diet, or went⁢ to the ⁤doctor more often when they needed ⁢it.

Although⁤ the researchers took into account⁤ many factors related to diet, lifestyle and wealth, they showed that eating dark chocolate ⁣prevents type 2 diabetes. ⁤ 2 ​would require a clinical trial on a⁢ large group of people. Half ⁣of them should be “given” dark chocolate and the other half ​milk chocolate ‍and ⁤followed for decades: an unrealistic and expensive⁤ experiment ⁢to investigate the​ relationship between a single food and a chronic disease ‍such as⁢ diabetes.

The benefits of dark chocolate: the role of flavonoids

But why did‍ the ‌study reveal these results?‍ how ‌are they explained? “Dark chocolate and milk chocolate‌ have similar amounts of calories, sugars and saturated fats,”​ hypothesizes first ⁣author Professor Qi⁢ Sun, “but dark ⁣chocolate ‌contains more ‌cocoa, and this⁣ might potentially be the key to its benefits for health”.⁣

Cocoa is ⁣a seed extract rich in fiber and beneficial plant compounds called flavonoids.Much research suggests this Flavonoids ⁢have antioxidant and anti-inflammatory effects ‍ and ⁢may help⁤ keep blood⁤ vessels clear, which may explain cocoa’s health benefits. Some ⁣small clinical ⁣studies suggest that consuming dark chocolate or cocoa⁣ may‌ lower blood pressure and improve insulin sensitivity and resistance, both of which influence ⁤the risk of developing type 2 diabetes.

The failure of supplements

Not all studies have found beneficial effects, and some have used concentrated cocoa ⁣supplements that contain ​more‌ flavonoids ⁢than a typical dark chocolate bar.⁢ “Supplements based on concentrated cocoa⁢ flavonoids are not effective”underlines⁢ Stefano Erzegovesi, “and this is another ‌example of the synergistic ‌effect of natural foods: we are talking about⁣ flavonoids, but​ the effect of ⁣cocoa could be linked to ⁣a thousand other synergistic micronutrients, which perhaps have not yet been discovered”.

What and how much dark chocolate can you eat

“For both chocolate – reflects Erzegovesi – and coffee (they are ‘relatives’ due to the type of flavonoids they ⁤contain and, not in vain, they are both very bitter), Paracelsus’‍ saying ‘it is the dose that makes the‌ poison’ ⁤is‍ valid ‘. At low doses⁣ the value of antioxidants prevails, hence its ⁢beneficial effect, at high⁣ doses the substances ⁣that, in excess, are not ⁢good for health prevail: caffeine for coffee, sugar and saturated fats for chocolate.’

Dark⁤ chocolate can be part of a healthy diet, but it’s best to choose a variety with at least ​70%⁢ cocoa: “It’s a good compromise between lots of flavonoids, but not too‍ bitter like in the 90%, and not too​ much sugar,” says Erzegovesi. ​A delicacy that is good for your health (without exaggerating,of course) are​ nuts covered ⁣in dark chocolate,as ⁤they also contain phytonutrients,healthy fats and fiber.The right dose?⁢ “Ten grams a day”, advises nutritionist⁣ Erzgovesi, “which is equivalent to⁢ two small squares or one large square”.⁤


What are the key differences in‌ health ⁤benefits between dark chocolate and milk chocolate?

Title: Dark Chocolate and Diabetes: An Insightful Discussion⁤ wiht Professor Qi Sun

Time.news Editor: ‍ Good afternoon, Professor Qi Sun, and thank you for joining us today. Your recent study published ‌in the British medical⁢ Journal highlights a fascinating association between dark chocolate consumption and a lower risk of developing type 2 diabetes. ⁣Can ⁤you provide us with an ⁤overview of your findings?

Professor Qi ⁤Sun: Good afternoon! Yes, I’m excited to discuss our findings. Our research followed over 190,000 healthcare workers for ‌nearly four decades. Previous dietary ⁢questionnaires revealed that participants ​who consumed at least five servings of chocolate weekly had ⁢a ⁢10% lower risk of ⁣type 2 diabetes compared to those who rarely ate chocolate. Strikingly, those who favored dark chocolate ‌saw an even more ⁤significant decrease—21% lower risk—indicating that dark ​chocolate could⁤ have a favorable role in a healthy⁤ diet.

Time.news Editor: Those statistics are certainly intriguing. However, you ​emphasized that the study ‍is observational rather than causal.⁣ Can you‍ elaborate on what that means for the implications of your findings?

Professor Qi Sun: ⁣ Absolutely. While we ‌identified a correlation between darker chocolate ​consumption and lower diabetes risk, ‌we cannot definitively say that chocolate consumption⁣ directly‌ prevents diabetes. Correlation does not imply causation; it’s likely that individuals​ who consume more dark chocolate also lead healthier lifestyles ‍overall. They⁢ may exercise more, maintain a balanced diet, and have good healthcare practices, all of which⁤ contribute to their lower risk.

Time.news Editor: That⁤ makes sense. In light of these ⁢findings, how should the public ⁤approach chocolate ⁢consumption? Is there a recommended quantity they should⁢ aim for?

Professor Qi Sun: It’s essential ⁣to treat dark chocolate not⁢ as a ‘magic bullet’ but as part ‍of a complete healthy diet. We suggest moderation—consuming about five ⁢servings of dark chocolate per week, which averages to about 30-50 grams a ⁢day, can be a reasonable amount. However,one‌ should always consider individual ⁤health conditions and dietary⁢ patterns,and opting for quality dark​ chocolate with higher cocoa content is crucial.

Time.news editor: Your research highlighted some stark‍ differences⁢ between dark and milk chocolate‌ in relation to diabetes​ risk.Can you share why milk chocolate wasn’t associated with the same protective⁣ benefits?

Professor Qi sun: Certainly! While⁢ dark chocolate is rich in flavonoids and antioxidants, milk ⁢chocolate often contains higher sugar and fat levels, which could lead to weight gain and other health issues. Our ⁤analysis ⁤showed that participants who consumed milk⁢ chocolate not only ⁢didn’t have the same‍ protective factor but where also more likely to⁤ gain weight,‍ which is a significant risk ⁢factor ⁢for developing type 2 diabetes.

Time.news editor: Interesting! There’s always a discussion about the potential downsides of certain foods. How should we interpret the limitations of the study, especially with respect‌ to generalizing these findings?

Professor qi Sun: It’s ⁣vital to approach ‍these ⁣findings with ​caution. Our study provides a⁣ foundation for further‍ exploration, but we must acknowledge its observational nature.‌ Other​ factors such as lifestyle ⁢choices, genetics, and socioeconomic status play a role in ⁣diabetes risk, and these can complicate interpretations of‌ our results.‍ Future⁣ research can help ⁣unpack⁢ these relationships more thoroughly.

Time.news Editor: Thank you for shedding‍ light on this topic, Professor Sun. For our‍ readers⁤ who might ⁤be ​inspired to integrate​ dark chocolate into ​their diets, ‌could you recommend‌ some practical tips on how to enjoy dark chocolate ‌while maintaining overall health?

Professor Qi Sun: Certainly! When enjoying dark chocolate, choose varieties with at least 70% cocoa content⁢ for maximum health benefits. Pair it with⁤ fruits,‍ nuts,⁢ or even use it ‍in guilt-free baking. Also, savoring small portions can definitely help satisfy cravings without overindulging. Balancing it with regular physical activity and a nutritious diet will maximize its ⁤potential benefits.

Time.news‌ Editor: Wonderful‌ insights! Thank you once ⁢again for joining us and sharing your valuable ‍research findings. Your contributions to understanding nutrition⁣ and health are truly appreciated.

Professor Qi Sun: Thank you for having me! It’s been a pleasure discussing this important topic.
