Does Coffee Spike Insulin

Coffee can be good for your insulin secretion and functioning if it is done right. Studies have shown that chronic and regulated amounts of coffee consumed over time can have advantageous effects on insulin and increase insulin sensitivity in the body.

On the other hand, high doses of caffeine from coffee can be bad for the insulin hormone and reduce the bodys response towards it. This can be bad for diabetic health as insulin is responsible for keeping blood sugar levels under control.

Therefore, it all depends on the frequency of coffee consumption and the intensity of caffeine. These are important factors to consider, and alter your choices accordingly to gain proper benefits.

Caffeine is naturally found in coffee beans. But low levels of it do not have any harmful effects on the body. 400mg of caffeine, which equals around 4 to 5 cups of coffee, is safe. But when we talk about diabetic individuals, these numbers change.


Diabetic patients have a different response to caffeine than non-diabetics, and hence, must be more cautious regarding the consumption of caffeinated coffee.

Therefore, decaffeinated coffee is a good option that fuels better insulin responses in the body and is also comparatively healthier than regular types of coffee.

The amount of antioxidants found in decaffeinated coffee is higher than that found in regular coffee. The process of decaffeination adds in more nutritional value and decreases harmful caffeine from it.

It Lowers Your Risk Of Parkinsons

No one wants to develop a neurodegenerative disease particularly those whove seen a family member go through it. Parkinsons is associated with a drop in dopamine.

Regular coffee drinkers have been shown to have a 32-60% reduced chance of developing this disease.

Okay, so those catecholamines described above include the production of adrenaline .

Adrenaline is known as the flight or fight hormone. It helps your body endure intense stress good or bad like a competition, a rollercoaster ride or a car accident.

Adrenaline helps you endure that stressful event by telling your liver to release stored energyglucose!

Your liver has stores of glucose, known as glycogen, that it releases at different times every single day. That glycogen is then broken down and converted into glucose to give your body fuel.

During everyday life, your liver is releasing tiny amounts of glycogen between meals to give your brain that second-by-second delivery of glucose it needs in order to function.

During stressful events like CrossFit or a car accident or a cup of coffee your liver will release a larger dose of glycogen, giving your body a larger dose of glucose to use for fuel.

And that is how caffeine spikes your blood sugar.

Note: Coffee consumption, especially in the evening, can also decrease sleep quality for some people, which is a known course of decreased insulin sensitivity.

Caffeine And Insulin Resistance

A study consisting of 10 people with type 2 diabetes set out to determine the impact of regular caffeine consumption on overall insulin levels.

All participants were regular coffee drinkers, consuming about 4 cups of coffee per day, but they all stopped drinking coffee during the study. Then half of them were given capsules containing 250 mg of caffeine, and the other half were given placebo pills containing zero caffeine.

The result, according to the study: On the days the patients took caffeine, their bloodsugar levels were 8% higher. And after every meal including dinner their blood sugar spiked higher than it did on the day they had no caffeine.

Does this mean people with diabetes shouldnt drink coffee and other caffeinated beverages? Not necessarily. It means we should look closely at our caffeine consumption and moderate it just like we would with other things that impact our blood sugar levels.

Just because black coffee and green tea contain zero calories doesnt mean we should drink them without limits. Instead, caffeine should ideally be something we consume carefully and set personal limits around for the sake of our overall diabetes health.

Increased Longevity & Cancer Protection

Coffee is valued for its high antioxidant value and phytochemicals, so it is no surprise that coffee has been linked to a decreased risk for certain types of cancers. It also may promote longevity.

Why Are Green Tea And Coffee Beneficial For Health And Diabetes

Is Coffee Bad for Diabetics? Does It Affect Blood Sugar ...

Research suggests that phenols and caffeine in coffee may be responsible for the reduced risk of developing type 2 diabetes, while another study found that decaffeinated coffee was equally effective and suggested that components other than caffeine are responsible for the beneficial effect.

The researchers noted that a phenolic compound called chlorogenic acid reduces oxidative stress and glucose absorption in the intestines, and this may be key in how coffee prevents diabetes.

Regarding green tea, compounds called catechins may improve glycemic response, but the beneficial effects in diabetes are inconclusive. Green tea is especially high in a polyphenol called epigallocatechin gallate, or EGCG, a powerful antioxidant that has been shown to have anti-cancer capabilities that may even be able to help halt tumor growth. Green tea contains more EGCG than other types of tea.

Past research suggests that losing many hours of sleep over one and/or multiple nights can have negative metabolic effects, so it is reassuring to learn that a single night of fragmented sleep does not have the same effect. However, strong black coffee consumed before breakfast substantially increased the blood glucose response to breakfast by around 50 per cent. This new study reveals that the common remedy of drinking coffee after a bad night’s sleep may solve the problem of feeling sleepy but could create another by limiting your body’s ability to tolerate the sugar in your breakfast.

Does Coffee Affect Blood Glucose And Insulin

Plain coffee does not seem to directly increase levels of blood sugar, or blood glucose. This is good news for people with diabetes who like black coffee.

However, some research suggests that the caffeine in coffee could impair insulin sensitivity, which is not ideal for people with diabetes.

That said, other compounds in coffee notably magnesium, chromium, and polyphenols may play a role in improving insulin sensitivity, which may offset the effects of caffeine.

Because of this, some experts suggest that people with diabetes drink decaffeinated coffee to get the benefits of components such as antioxidants and minerals without affecting insulin sensitivity.

Caffeine is the major stimulant in coffee. It occurs naturally in coffee beans and green tea. Caffeine speeds up the central nervous system and may increase mental alertness, relieve tiredness, and improve concentration.

In the general population, the Food and Drug Administration report, 400 milligrams of caffeine or 4 to 5 cups of coffee per day usually have no negative effects.

However, because research in people with diabetes has been mixed, it is a good idea to ask a healthcare provider about how much coffee is safe.

Some people are more sensitive to the effects of caffeine than others. This is true for people with or without diabetes.

Regular Coffee Decaffeinated Coffee And Insulin Sensitivity In Type 2 Diabetes

Health Benefits Of Drinking Black Coffee

Regular coffee, which contains caffeine, is shown to impair insulin sensitivity in people with Type 2 Diabetes. Caffeine has been shown to affect the bodys response to insulin, which is called insulin sensitivity. People with type 2 diabetes develop an inability either to secrete insulin or to respond to higher blood sugars the latter situation is known as insulin resistance, and thats where coffees effects need to be considered.

Research published in Diabetes Care in 2002 announced that caffeine decreased insulin sensitivity in healthy male volunteers by 15 percent when compared to placebo. Then, the American Journal of Clinical Nutrition in 2008 published a study, which found that coffee with caffeine significantly impaired insulin sensitivity in healthy men, while decaffeinated coffee did not have the same effect.

Regular high caffeine consumption, over a 4 week period, has been shown to impair insulin sensitivity in people with type 2 diabetes.

In addition, the study also wanted to look specifically at whether caffeine and caffeinated coffee had the same effect when it came to insulin resistance, citing other research that shows moderate coffee intake protects people against type 2 diabetes.

Having said that, though the researchers found a relationship between higher coffee consumption and lower sensitivity to insulin, they recognised that the rapid transition to having more coffee may have produced an atypical or emphasised response by the body.
