New Coffee Compounds May Help Control Blood Sugar in Type 2 Diabetes, Study Finds

Coffee not just gives you energy but is capable of much more. According to a new study, certain compounds found in roasted coffee beans can slow how quickly sugar enters the bloodstream, a finding that

could one day support new foods aimed at managing type 2 diabetes. Scientists have been able to identify not one but three previously unknown compounds in roasted coffee that strongly block α-glucosidase, a key enzyme for carbohydrate breakdown, potentially slowing sugar entry into the bloodstream and helping control type 2 diabetes. Experts say these findings are built on existing knowledge that coffee's natural polyphenols, like chlorogenic acid, improve insulin sensitivity and reduce inflammation. The research, led by Kunming Institute of Botany and the Chinese Academy of Sciences, was published in the journal Beverage Plant Research and has come to the conclusion that coffee offers health benefits beyond basic nutrition.

How was the study conducted?

Scientists say it is challenging to find compounds in foods since they are interlinked with chemicals. And so, for this study, the research team used advanced lab tools, including nuclear magnetic resonance and liquid chromatography-mass spectrometry, to carefully analyze roasted Coffea arabica beans A three-step screening process was used by the scientists to narrow down the most chemically active portions of the coffee extract. After further testing and purification, they isolated three new compounds, which they named caffaldehydes A, B, and C. All three compounds strongly blocked α-glucosidase. In the end it was found that the compounds in coffee were more potent than acarbose, a common diabetes medication.

What about caffeine?

ou might be wondering if the caffeine in coffee plays a significant role. The answer is both yes and no. Caffeine itself may have a minimal impact on lowering the risk of diabetes. Instead, it is the combination of bioactive compounds, including antioxidants, that work together to create these positive effects. However, it is worth noting that excessive caffeine intake can lead to jitteriness, anxiety, or even sleep disturbances. Therefore, while coffee can be beneficial in reducing diabetes risk, it’s essential to consume it in moderation.

How much caffeine is too much?

While coffee offers significant health benefits, including potential diabetes prevention, it is essential to know your caffeine limits. Overconsumption of caffeine can lead to various side effects such as insomnia, rapid heart rate, and digestive issues. The FDA recommends a maximum daily caffeine intake of 400 mg for most adults, which is roughly equivalent to four 8-ounce cups of coffee.

How can coffee prevent type 2 diabetes?

Improve insulin sensitivity

Insulin regulates blood sugar levels, and since it becomes less effective in those with diabetes, bioactive compounds in it can enhance insulin sensitivity, meaning the body can use insulin more effectively, reducing the risk of developing type 2 diabetes.

Antioxidant power

Both coffee and tea are packed with antioxidants, which help protect your cells from damage caused by free radicals. This damage can lead to chronic inflammation, which plays a significant role in the development of diabetes.
