If you're a diabetic, you may be wondering if you can drink coffee. Coffee has gotten a bad rap over the years, but is it actually bad for diabetics? In this article, I'll discuss if there a best coffee for diabetics, whether or not caffeine is bad for diabetics to how much coffee per day is safe for people with diabetes. 

How Does Coffee Affect Diabetes?

There is some evidence that suggests coffee consumption can interfere with blood glucose levels, but the research on this topic is inconclusive. Some studies suggest that coffee may create blood sugar spikes in people with diabetes, while others show no effect. However, it's important to keep in mind that most of these studies are observational and don't prove a cause-and-effect relationship. 

What Are the Benefits of Drinking Coffee?

Drinking coffee is related to lots of benefits. Coffee contains many antioxidants and polyphenols which have anti-inflammatory and anticarcinogenic properties. Coffee has been linked with a decreased risk of Parkinson's disease, type 2 diabetes, heart disease, stroke, and Alzheimer's disease.

What Is The Best Coffee for Diabetics?

The best coffee for diabetics is a matter of personal preference. Some people find that drinking black coffee helps to control blood sugar levels, while others prefer to drink espresso or lattes with low-fat milk. As long as you're not adding sugar or cream, any type of coffee should be fine.

The best way to make sure you're getting the healthiest cup of joe is by brewing it yourself using a French press or an Aeropress. If you don't have time to brew your own coffee, look for brands that are organic and fair trade. Coffee beans that are organically grown tend to be lower in acidity than conventionally grown beans. And, because fair trade coffees are ethically sourced, they often have a richer flavor than conventional coffees.

Green coffee beans are also a perfect choice for diabetics. Green coffee beans are unroasted, so they retain more of their natural nutrients. Roasting can destroy some of the antioxidants and health benefits of coffee. The health benefits of green coffee may be attributed to its chlorogenic acid, which is a powerful antioxidant that has been shown to keep blood sugar levels stable in our bodies.

Does Coffee Increase Blood Sugar Levels?

Coffee doesn't cause high blood sugar levels, but it can affect how quickly they return to normal after a meal.

Caffeine may alter how your body responds to insulin, the caffeine may reduce your insulin sensitivity. This implies that the hormone's cells don't react as strongly to it as they did previously.

After you eat or drink, they don't hold as much sugar in your blood. As a result, your body produces more insulin and you have higher blood sugar levels after meals.

Is Caffeine Bad for Diabetics?

So, is caffeine bad for diabetics? In general, moderate amounts of caffeine are safe for people with diabetes. However, if you're sensitive to caffeine or if you've been diagnosed with prediabetes, it may be best to limit your intake. 

How Much Caffeine Is Too Much?

According to the American Diabetes Association (ADA), up to 400 milligrams of caffeine per day is safe for most people with diabetes. That's about four cups of brewed coffee. The total caffeine amount in your coffee depends on the size of your cup and the brewing method.

Too much coffee consumption and caffeine can have an effect on your blood glucose levels, so it's best to stick to the recommended amount.

Your blood sugar levels rise after meals. Caffeine may make it more difficult to return them to a normal level. This might result in higher and uncontrolled blood sugar levels.

If you're not sure about the caffeine content in your coffee, check the label or ask your barista. 

Which Is Better for Diabetics Tea or Coffee?

If you're looking for a lower-caffeine option, try an organic decaffeinated coffee or an herbal tea or green tea. Teas made from herbs like ginger, chamomile, lavender, and rosehip are all good options for diabetics. They're low in calories and sugar, and they contain antioxidants that can help improve blood sugar control.


In general, coffee is considered safe for people with diabetes. However, it's important to moderate your intake and watch out for added sugars and creamers. The best way to enjoy a cup of coffee while still managing your diabetes is by brewing it yourself with organic, fair-trade beans or choosing an unsweetened version. And if you're sensitive to caffeine, be sure to stick to the recommended amount per day.
