If you're concerned about your susceptibility to diabetes, a simple solution may be to brew yourself a cup of coffee. A recent study published in the Journal of Clinical Nutrition indicates that drinking coffee may be associated with a decreased risk of developing type 2 diabetes.
The study, which is set to be printed in May 2023, examined the impact of coffee consumption on two vast populations comprising over 150,000 individuals. It focused on the connection between coffee intake and markers of inflammation and discovered that the anti-inflammatory properties of coffee may provide protection against type 2 diabetes. The research found that an extra cup of coffee per day lowered the likelihood of contracting the disease by 4-6%.
How Coffee Could Potentially Lower the Probability of Developing Type 2 Diabetes
While previous research has established a connection between drinking coffee and a decreased risk of type 2 diabetes in those with a family history, a recent study has shed new light on how coffee's antioxidants can potentially reduce inflammation and protect against diabetes in individuals of various health backgrounds.
Inflammation is increasingly recognized as a significant factor in determining a person's likelihood of contracting type 2 diabetes. "Chronic inflammation, which occurs on an ongoing basis, can have negative effects on health and heighten the risk of developing conditions such as type 2 diabetes," according to Carrie Gabriel, MS, RD, of Steps 2 Nutrition. "A lifestyle that emphasizes anti-inflammatory foods and physical activity has been demonstrated to lower inflammation and safeguard against diabetes."
Thankfully, coffee is a rich source of inflammation-fighting antioxidants. "Coffee has many bioactive compounds, including chlorogenic acids and lignans, which possess antioxidant and anti-inflammatory qualities," says endocrinologist Dr. Adnan Zahid, MD. "These compounds have the potential to decrease inflammation and oxidative stress, two factors that contribute to the development of diabetes."
What Amount and Type of Coffee is Optimal?
The study published in the Journal of Clinical Nutrition indicates that drinking one extra cup of coffee per day (up to six cups) may lower the risk of type 2 diabetes. However, excessive caffeine consumption can cause anxiety and jitters, so it's essential to be mindful of intake. "Ideally, an average person should not consume over 400 milligrams of caffeine per day, equivalent to two cups of coffee," notes Gabriel.
Individuals with diabetes must also monitor their coffee intake and avoid adding sugar or flavored creamers. Gabriel suggests limiting caffeine consumption to one cup per day, as even a single cup of coffee can cause glucose levels to fluctuate rapidly in people with type 2 diabetes.
Dr. Zahid emphasizes consulting a doctor before consuming excessive amounts of coffee. "I encourage my patients to adopt a healthy lifestyle and consult their healthcare provider before altering their diet or physical activity," he says.
The research suggests that filtered coffee and espresso are the best types to drink for reducing the risk of type 2 diabetes.
