A recent study has highlighted the potential benefits of caffeine in reducing the risk of type 2 diabetes. Published in BMJ Journals, the research reveals that individuals with higher levels of caffeine in their bloodstream are 19% less likely to develop type 2 diabetes compared to those with lower caffeine levels. The study further suggests that nearly half (43%) of this effect can be attributed to caffeine’s role in helping to reduce body weight.
While the study did not specify the source of caffeine, whether from coffee, tea, or other sources, it reinforces the understanding within the nutrition community that caffeinated beverages contribute positively to cardiovascular and weight management health.
Kathleen Moore, a registered dietitian at The Ohio State University Wexner Medical Center, explains that caffeine stimulates the production of adrenaline, which may help break down fat, curb appetite, and enhance physical activity. However, Moore suggests that coffee—especially without added sugar, cream, or flavorings—has a more significant impact on reducing the risk of type 2 diabetes, as it contains higher levels of caffeine than beverages like tea.
Moderation remains crucial, as excessive caffeine intake can lead to adverse effects such as anxiety, sleep disturbances, and increased heart rate. Moore advises limiting daily caffeine intake to 400 milligrams to avoid these health risks.
Incorporating caffeinated drinks like coffee or tea in place of sugary beverages is one way people have successfully managed their weight. Green tea, for instance, has also shown promise in boosting fat breakdown and increasing levels of leptin, a hormone associated with fullness. Still, Moore cautions that individuals with hypertension or other conditions may want to opt for lower-caffeine beverages.
While the study provides compelling evidence of caffeine’s role in health, the full range of its effects continues to be explored, offering diverse options for individuals looking to improve their metabolic health.
