What Are Some Health Benefits Of Coffee
Numerous studies have shown that drinking multiple cups of coffee a day will actually . Both caffeinated and decaffeinated coffee has been associated with reduced diabetes risk.
The caffeine in coffee has also been shown to stimulate weight lossby increasing energy use and suppressing the accumulation of fat cells. This weight loss is beneficial in type 2 diabetes, given the link between excess weight and higher risk of disease.

Is Coffee Good For Diabetes
The average American adult drinks around 16 oz. of coffee a day. Thats two cups, with each cup containing about 140 milligrams of caffeine.
For most healthy people, up to 400 mg of caffeine a day isnt a problem. In fact, its possible that a daily cup of coffee can reduce the risk of developing type 2 diabetes in the first place.
In 2015, researchers published the results of a 10-year follow-up study¹ that looked at the connection between coffee drinking and diabetes. The original study followed 1,514 men ages 18 to 87 and 1,528 women ages 18 to 89 who didnt have diabetes when they enrolled in the study .
They divided the group into coffee abstainers, casual drinkers , and habitual drinkers, who drank at least 250 ml daily. During 10 years of follow-up, 191 study participants were diagnosed with type 2 diabetes. The authors found that habitual drinkers had a 54% lower risk of being diagnosed with diabetes compared to abstainers.
According to Koloverou, circulating levels of SAA may affect glucose homeostasis. “Postchallenge hyperglycemia might be an intermediate variable linking SAA to the development of type 2 diabetes, she explained.
The researchers defined a cup of coffee as 150 ml. This is about 2.5 to 3 cups of brewed coffee, or about three cups of instant coffee.
So we may hypothesize that apparently healthy individuals with no history of cardiovascular disease may benefit from daily consumption of this amount of coffee, she said.
The Theory Behind Coffee Reducing The Risk Of Type 2 Diabetes
Lets look first at why some researchers believe drinking coffee can lower the risk of developing diabetes.
One study of more than 12,000 people aimed to prove that the metabolic effects of coffee may reduce the possibility of diabetes.
After making adjustments for varying factors including:
- Body mass index
The study found coffee drinking showed positive effects on blood glucose levels.
In observational studies in people who have not been diagnosed with diabetes, coffee helped with reducing blood sugar and insulin levels the main risk factors for diabetes.
Studies show that drinking regular or decaf coffee on a daily basis can lower your risk of developing diabetes by 23 to 50 percent.

The Risks Of Fasting With Diabetes
As well as not eating food , fasting is also usually a time of prayer, reflection and purification. If you treat your diabetes with certain medications such as insulin, there is also the danger of the blood sugar levels after fasting becoming too low. This can lead to a hypo, or having your blood sugar levels too high which can lead to diabetic ketoacidosis , which would require hospital treatment. The symptoms of DKA include feeling very thirsty and passing a lot of urine.
If someone is fasting and does not take in fluids to reduce their thirst, this will accelerate dehydration and they will require urgent admission to hospital.
If youre worried about fasting with diabetes, check with your GP or diabetes team, particularly if youre not sure what to do with your diabetes treatment during fasting. If you cant get hold of them, its best not to fast. And if you require urgent medical help you can use the NHS 111 online service.
Test For Type 2 Diabetes
Health care professionals will ask you to fast for eight to 12 hours before you take a blood glucose test, says the Mayo Clinic. Many doctors recommend you get the test first thing in the morning to make it easier on yourself, having had nothing but water. Medline Plus also suggests that you don’t exercise, smoke or chew gum before this procedure.
The glucose tolerance test for Type II diabetes requires several steps, says the Mayo Clinic. First, you’ll give a sample of blood from a vein in your arm â that number will provide your fasting blood glucose level. Then you’ll drink a glass of glucose solution containing 75 grams of sugar. After two hours, your glucose will be measured again.
If your blood glucose level is normal, it will be below 140 milligrams per deciliter of blood. If it measures between 140 and 199 milligrams per deciliter, you may have impaired glucose tolerance, also known as pre-diabetes. This means you’re at risk of developing diabetes and heart disease.
If the level is above 200 milligrams per deciliter, you may have diabetes. Your doctor may want you to repeat the blood work test if that’s the case.

Effect On People Without Diabetes
Caffeine intake may actually help prevent the development of type 2 diabetes, explains Science Daily. People without diabetes are able to make up for the rise in glucose through the production of extra insulin. Insulin is the hormone that drives glucose clearance, and the body just needs to pump a little more out to take care of the effects of caffeine on blood glucose.
Coffee And Type 2 Diabetes: Is Coffee Safe To Drink For Type 2 Diabetes

Coffee And Its Effects On The Body
The FDA has generally suggested 400 mg of caffeine as the limit for healthy adults to drink coffee daily. If you have diabetes, a lower limit will be helpful since the high concentration will negatively impact the blood sugar level.
Coffee and caffeine, in general, have various effects on the body. According to a recent study, regular coffee consumption directly affects insulin, where the impact varies depending on the individuals health and overall caffeine consumption.
As per studies, coffee doesnt just provide energy and promote faster metabolism. Here are some of the common substantial effects of consuming coffee:
Why Caffeine Impacts Glucose And Insulin
But why does caffeine impair glucose metabolism? Caffeine stimulates the central nervous system , a metabolite that helps regulate our energy levels.
In the brain, adenosine acts as a neurotransmitter and promotes restful sleep by tamping down the activity of neurostimulators like dopamine. Caffeine can bind to adenosine receptors in the brain, preventing adenosine from binding at those sites and curbing its ability to inhibit dopamine. The effect: we feel more alert. Scientists have found genetic variation in those adenosine receptors among different people, which may explain why individual responses to caffeine vary.
The reason adenosine affects glucose is that in addition to the brain, there are adenosine receptors throughout the body, including in adipose tissue and muscle tissueboth sites where insulin facilitates glucose uptakeas well as in the liver, which controls the production of glucose and release of stored glucose. Scientists still arent precisely sure which adenosine receptors play the most crucial role in modifying glucose uptake and insulin sensitivity. But a recent animal study suggests its effect on muscle tissue uptake exerts the most significant influence. Either way, multiple studies demonstrate that restricting the action of adenosine, as caffeine has been shown to do, decreases insulin sensitivity.
If caffeines negative short-term effect on glucose metabolism is well established, so is coffees desirable impact on the risk of Type 2 diabetes.

How Does Caffeine Raise Your Blood Sugar
Caffeine signals your brain to release or produce adrenaline often referred to as the fight or flight hormone that helps you endure stressful events like a competitive sport, a car crash, or even a rollercoaster ride.
Adrenaline makes your heart beat faster, increases your muscles ability to contract, and tells your liver to release some of its stored glucose to give you energy.
That stored glucose is then released into your bloodstream but for those of us with diabetes, we dont produce additional insulin to accompany the extra glucose.
And thus, you can easily see your blood sugar spike by 100 points from a simple cup of black coffee.
Caffeine Diabetes And Insulin
A study examining the relationship between caffeine, insulin, and blood sugar found that diabetic people who consumed approximately the same amount of caffeine as you would get from drinking two cups of coffee had more variability in their blood sugar levels.
Specifically, the study broke diabetic subjects up into two groups, one taking two 250 milligram caffeine pills per day and the other a placebo. The caffeine pill group had 8% higher blood sugar levels than the placebo group on days when they did not take the caffeine pills.
The reason for this effect is how caffeine affects your bodys natural insulin sensitivity. Consuming caffeine kicks off a domino-like chain of chemical reactions in your body that ultimately means it doesnt process sugar as effectively. Caffeine intake raises epinephrine levels, and epinephrine reduces your bodys insulin production.
Caffeine also blocks adenosine, a molecule that helps regulate insulin production. In combination, these two effects mean that caffeine reduces your bodys ability to produce and regulate insulin levels, which indirectly raises blood sugar. If you only drink coffee occasionally, the ups and downs of insulin sensitivity on days you dont drink coffee causes blood sugar levels to fluctuate, making it difficult to monitor and treat diabetes.

Caution: Birth Control Pills
Estrogen in birth control pills can affect the way a person with diabetes may respond to insulin. The American Diabetes Association advises women with diabetes to use a birth control pill containing norgestimate and a synthetic estrogen. The ADA also says birth control injections and implants are safe for women with diabetes, but suggests they still have some effect on blood sugars. If women elect to use these birth control methods, they should monitor their blood sugar levels, especially for several weeks when these agents are first administered. Women with diabetes should discuss their birth control options with their doctor.
How Does Coffee Affect Blood Sugar Levels
Scientists are still trying to figure out how caffeine affects blood sugar levels and insulin sensitivity. One of the theories suggests that caffeine raises epinephrine. This hormone may prevent your cells from processing glucose by inhibiting insulin secretion.
Caffeinated coffee can also indirectly affect your blood sugar levels by causing a lack of sleep. People with type 2 diabetes who don’t get sufficient sleep may suffer from lower insulin sensitivity. Even if a person is sleep-deprived for just one night, they may experience higher insulin resistance.

Artificial Sweeteners May Alter Blood Sugar Response
Many people with diabetes reach for diet drinks as a substitute for regular soda or juice because they assume that sugar-free beverages won’t raise their blood sugar. But a review published in January 2021 in Frontiers in Nutrition suggested that artificial sweeteners may not be completely neutral after all, and may contribute to impaired glucose homeostasis.
But the research isn’t definitive most government and medical institutions maintain that most artificial sweeteners have no effect on blood sugar. So what could be going on? Mayo Clinic suggests that people can experience a rebound effect when consuming artificial sugars. They consider the sugar-free food healthy, so end up consuming excessive amounts or eating other carb-filled foods because they think the diet drink lets them afford it. The clinic also notes that some noncaloric sweeteners can cause diarrhea, which can contribute to dehydration.
“If you drink a lot of diet soda then you might want to cut back and see if it has an impact on your blood glucose,” says Patty Bonsignore, RN, CDCES, a nurse educator at the Joslin Diabetes Center in Boston. Keep things sugar-free by turning to water or seltzer as opposed to regular soda or juice.
How Caffeine Impacts Your Blood Sugars
While coffee and caffeine have been shown to possibly prevent the condition in people who dont already have it, that morning cup of Joe could have some serious effects on your diabetes.
The Science
According to WebMD, caffeine can impair insulin reaction. This means it may take more time for your dose of insulin to fully kick in. Caffeine can also increase your bodys resistance to insulin. This can ultimately lead to high blood sugar levels and to further diabetes complications.
In addition, a 2008 Duke University study showed that caffeine may have an impact on your blood glucose levels. The study examined people with type 2 diabetes. One group of participants took 500 mg caffeineabout the equivalent of about two cups of coffeeevery day for a week, while the second group abstained from caffeine. Each persons blood glucose levels were tested multiple times throughout the week, and it was found that those who drank caffeine had blood sugars around 8 percent higher than those who didnt take caffeine.
Alternative Solutions
So, whats the best option for people with diabetes who still want their coffee fix? Try making your order . Its also best to avoid added creamers, syrups and sweeteners. If youre really craving some extra flavor, opt for the sugar-free varieties. And make sure you say no-thanks to the mile-high swirl of whipped cream that tops most coffeehouse favorites.

Why Does Caffeine Have This Effect
Scientists are still learning how caffeine affects your insulin and blood sugar levels. But they think it may work this way:
- Caffeine raises levels of certain stress hormones, like epinephrine . Epinephrine can prevent your cells from processing as much sugar. It may also keep your body from making as much insulin.
- It blocks a protein called adenosine. This molecule plays a big role in how much insulin your body makes. It also controls how your cells respond to it. Caffeine keeps adenosine which plays a big role in how much insulin your body makes.
- It takes a toll on your sleep. Too much caffeine can keep you awake. Lack of sleep may also lower your insulin sensitivity.
