Coffee and risk of type-2 diabetes

By Canada Cloud Pharmacy | Published Saturday 10 July 2021

Are you one of those who begin the day with a big mug of coffee? Although the quantity of caffeine in coffee varies depending on the types of coffee and several other factors, coffee happens to be the most significant source of dietary caffeine. While caffeine has been linked to several medical conditions due to its beneficial and adverse effects, drinking coffee in moderate amounts is beneficial. Here we will discuss the link between drinking coffee and a common health condition - type-2 diabetes.

Which factors affect the caffeine content in coffee?

Different coffee preparations will have different caffeine content. The following factors affect the caffeine content in coffee:

  • Type of coffee beans.

  • Type of roast.

  • Type of coffee (caffeinated or decaffeinated).

  • Serving size.

What happens in type-2 diabetes?

Your pancreas is responsible for insulin secretion, a hormone that controls glucose levels in the blood. In type-2 diabetes, either the pancreas does not produce enough insulin or does not work correctly. As a result, glucose gets accumulated, resulting in higher blood glucose levels. Diabetes can lead to complications involving the eyes, kidneys, and nerves.

What is the connection between coffee and type-2 diabetes?

While coffee is the most preferred beverage globally, you must be aware of the recommended intake of this high caffeine-containing drink. Several studies carried out in different countries worldwide suggest that habitual drinking of coffee is linked with lowering the risk of type-2 diabetes. Some studies also indicate that filtered coffee has a better capacity for lowering the risk of type-2 diabetes than boiled coffee. Caffeinated coffee also has more chances of reducing the risk of type-2 diabetes as compared to decaffeinated coffee. Some studies indicate a 12% lower risk of type-2 diabetes for every two extra cups of coffee.

How does coffee lower the risk of type-2 diabetes?

Some studies have proved that drinking coffee — whether caffeinated and decaffeinated may help reduce your risk of developing type 2 diabetes. Researchers have proposed several mechanisms by which coffee may lower the risk of type-2 diabetes. These are as follows:

  • In an animal study, caffeine has shown increased insulin sensitivity that positively impacts the glucose mechanism.

  • Caffeine also reduces the oxidative stress that may be the reason for type-2 diabetes.

  • Caffeine reduces glucose storage in the body acutely.

  • Several other ingredients in coffee, such as chlorogenic acid, magnesium, and quinidine, are also associated with lowering the risk of type-2 diabetes.

However, coffee also has specific adverse effects due to its caffeine content, and it is necessary to consume it as per the recommended intake. While some studies suggest that drinking coffee lowers the risk of type-2 diabetes, further clinical studies are needed to investigate the role of coffee in reducing the risk of type-2 diabetes. The effect of caffeine is different for every person.
