Coffee Type 2 Diabetes

How Does Caffeine Affect Your Blood Sugar?

How Does Caffeine Affect Your Blood Sugar?

Whether it’s from coffee, tea, soda, or chocolate, most Americans get caffeine every day. For healthy people, it’s usually a harmless perk-me-up. But if you have type 2 diabetes, caffeine may make it harder to keep your blood sugar in check. A growing body of research suggests people with type 2 diabetes react to caffeine differently. It can raise blood sugar and insulin levels for those with the disease. One study looked at people with type 2 diabetes who took a 250-milligram caffeine pill at breakfast and another at lunchtime. That’s about the same amount as drinking two cups of coffee with each meal. The result: Their blood sugar was 8% higher than on days when they didn’t have caffeine. Their reading also jumped by more after each meal. That’s because caffeine can affect how your body responds to insulin, the hormone that allows sugar to enter your cells and get changed into energy. Caffeine may lower your insulin sensitivity. That means your cells don’t react to the hormone by as much as they once did. They don’t absorb as much sugar from your blood after you eat or drink. This causes your body to make more insulin, so you have higher levels after meals. If you have type 2 diabetes, your body already doesn’t use insulin well. After meals, your blood sugar rises higher than normal. Caffeine may make it tougher to bring it down to a healthy point. This may lead to too-high blood sugar levels. Over time, this may raise your chance of diabetes complications, like nerve damage or heart disease. 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 (also called adrenaline). Epinephrine can prevent your cells from proce Continue reading >>

Coffee, Caffeine, And Risk Of Type 2 Diabetes

Coffee, Caffeine, And Risk Of Type 2 Diabetes

A prospective cohort study in younger and middle-aged U.S. women Abstract OBJECTIVE—High habitual coffee consumption has been associated with a lower risk of type 2 diabetes, but data on lower levels of consumption and on different types of coffee are sparse. RESEARCH DESIGN AND METHODS—This is a prospective cohort study including 88,259 U.S. women of the Nurses’ Health Study II aged 26–46 years without history of diabetes at baseline. Consumption of coffee and other caffeine-containing foods and drinks was assessed in 1991, 1995, and 1999. We documented 1,263 incident cases of confirmed type 2 diabetes between 1991 and 2001. RESULTS—After adjustment for potential confounders, the relative risk of type 2 diabetes was 0.87 (95% CI 0.73–1.03) for one cup per day, 0.58 (0.49–0.68) for two to three cups per day, and 0.53 (0.41–0.68) for four or more cups per day compared with nondrinkers (P for trend <0.0001). Associations were similar for caffeinated (0.87 [0.83–0.91] for a one-cup increment per day) and decaffeinated (0.81 [0.73–0.90]) coffee and for filtered (0.86 [0.82–0.90]) and instant (0.83 [0.74–0.93]) coffee. Tea consumption was not substantially associated with risk of type 2 diabetes (0.88 [0.64–1.23] for four or more versus no cups per day; P for trend = 0.81). CONCLUSIONS—These results suggest that moderate consumption of both caffeinated and decaffeinated coffee may lower risk of type 2 diabetes in younger and middle-aged women. Coffee constituents other than caffeine may affect the development of type 2 diabetes. High coffee consumption has been associated with better glucose tolerance and a substantially lower risk of type 2 diabetes in diverse populations in Europe, the U.S., and Japan (1–3). However, it remains unclear what co Continue reading >>

Coffee Consumption And Type 2 Diabetes

Coffee Consumption And Type 2 Diabetes

Print this page Coffee and risk of type 2 diabetes Epidemiological studies suggest that drinking 3-4 cups of coffee per day is associated with an approximate 25% lower risk of developing type 2 diabetes, compared to consuming none or less than 2 cups per day1,2. Research also suggests a dose response relationship15-17. A systematic review with a meta-analysis of 457,922 individuals and 21,897 newly-diagnosed cases of type 2 diabetes from eight different countries showed a statistically significant negative association between coffee consumption and subsequent risk of type 2 diabetes2. The dose response analysis concluded that every additional cup of coffee, up to 6-8 cups per day, was associated with a 5-10% lower risk of developing type 2 diabetes. Drinking 3-4 cups of coffee per day was associated with an approximate 25% lower risk of developing type 2 diabetes, compared to consuming none or less than 2 cups per day. Additional epidemiological studies and reviews from different countries have also confirmed the inverse association with coffee consumption3-13. Furthermore, a 10 year follow-up study from Greece highlighted the significance of long-term habitual coffee drinking against diabetes onset14. Further dose response studies have also been reported. A 2014 study concluded that participants who increased coffee intake by more than one cup per day over a 4 year period had an 11% lower risk of type 2 diabetes, whilst those who decreased coffee consumption by one cup per day had a 17% greater risk of type 2 diabetes15. A meta-analysis of prospective studies suggested a 12% reduction in risk of type 2 diabetes for every additional two cups of coffee per day, and a 14% reduction for every 200mg increment of caffeine per day. This review also suggested that the effect w Continue reading >>

Is Coffee Good For Diabetes?

Is Coffee Good For Diabetes?

Should people with diabetes drink coffee? If you do, should it be decaf or regular? The health effects of coffee have been well studied, but we still have no definite answer. I have to admit — I don’t drink coffee and never have. The closest I get is coffee ice cream. But some of this data has me thinking I should start. • Coffee reduces risk of death. In a study of over 700,000 people done by the University of Southern California, people who drank coffee were 18% less likely to die in the next 10–16 years. The study group included people of various races and ethnic groups. • Coffee is linked with lower risk of stroke. Since stroke is a major complication of diabetes, lowering your risk seems like a good idea. • Studies indicate that coffee lowers risk ofliver and mouth cancer, improves memory, and protects against Type 2 diabetes and Parkinson’s disease. • A recent study from India found that coffee drinkers have lower fasting blood sugars. Other studies have found that coffee improves insulin function. It may lower insulin resistance. • Some nutritionists say coffee is a major source of antioxidants, molecules that slow aging and tissue breakdown. Downside of coffee Coffee has some undesirable side effects. The Mayo Clinic states that consuming more than 500–600 milligrams of caffeine a day may lead to “insomnia, nervousness, restlessness, irritability, an upset stomach, a fast heartbeat, and even muscle tremors.” It’s worth noting that 500–600 milligrams a day is a lot (about six cups of coffee or nine ounces of espresso), but some research has linked even moderate amounts of caffeine to bad health effects, according to Medical News Today. Coffee drinking in pregnancy may increase the risk of low-birth-weight babies. Drinking coffee with a Continue reading >>

Caffeine And Diabetes: How Much Is Safe To Consume?

Caffeine And Diabetes: How Much Is Safe To Consume?

Navigating what you can and cannot eat and drink when you have type 2 diabetes can be tricky. Of course, there’s the obvious stuff you know is good to cut out or limit in your diet, like processed sweets and other refined carbohydrates, which can cause blood sugar levels to soar when eaten in excess. But what about those murkier diet staples, which seem to straddle the line between healthy and indulgent, but are ingrained in so many of our everyday rituals? For millions of people in various cultures around the world, caffeinated drinks are likely the sort of thing that comes to mind when we talk about food or drinks in a healthy diabetes diet that aren’t so cut-and-dried. If you’ve recently been diagnosed with type 2 diabetes or have been living with the disease for a while and are seeking better blood sugar control, the subject of caffeine in a diabetes diet is a fair concern. Caffeinated Drinks for Diabetes: Are They Safe? “For people already diagnosed with type 2 diabetes, studies have shown caffeine consumption decreases insulin sensitivity and raises blood sugar levels,” says Toby Smithson, RDN, CDE, who is based in Hilton Head, South Carolina. According to a review published in April 2017 in Diabetes & Metabolic Syndrome: Clinical Research & Reviews, five out of seven trials studied found that caffeine increases blood glucose and keeps levels higher longer. That doesn’t sound good, but if you’re accustomed to having your morning java, don’t skip out on the drink just yet. Some studies suggest that other components of caffeinated coffee may offer some benefits for people with diabetes. In a study published in March 2016 in the International Journal of Pharmacy and Pharmaceutical Sciences, researchers looked at coffee consumption in adults with and w Continue reading >>

Coffee, Caffeine And Type 2 Diabetes

Coffee, Caffeine And Type 2 Diabetes

There has been extensive research into whether consuming coffee (caffeine) is safe for those with type 2 diabetes as well as whether or not coffee could help prevent diabetes. With the ever rising population of people suffering with type 2 diabetes, it’s good to hear that the diabetic or potential diabetic has a friend in coffee. A healthy diet, low in sugar and refined carbs, is still the number one dietary measure to treat or reduce the risk for diabetes. Most research shows that coffee can be part of a diet that’s designed to prevent, treat, and/or possibly reverse type 2 diabetes. Type 2 Diabetes and Coffee Research Studies A study published by the American Diabetes Association showed that those who drink coffee have lower sugar and insulin levels. It also appears that regular coffee is better than decaffeinated, so coffee could even prevent the onset of type 2 diabetes.15 overweight but otherwise healthy men were given either decaf coffee, a placebo, or the chemicals chlorogenic acid and trigonelline dissolved in water, which are two of the main antioxidants in coffee. The participants’ glucose and insulin levels were checked after consumption of each throughout the trial period. The only sample that showed lowered sugar and insulin levels was the chlorogenic acid and trigonelline solution group. Src. Another study analyzed much the latest research concerning diabetes and coffee consumption and was conducted by Harvard’s Dr. Frank Hu. His team found that the risk of type II diabetes decreased by 9% for each daily cup of coffee consumed. Decaf coffee decreased risk by 6% per cup. Src. An 11 year study looked at the diabetes and coffee risk association in postmenopausal women. They found that women who consumed 6 cups of coffee had a 22% lower risk of develop Continue reading >>

[email protected] An alarming increase the prevalence of type 2 diabetes is forcing to constant analysis the lifestyle factors which can affect the risk of this illness. The research in the last ten years revealed new knowledge concerning the inverse association between habitual coffee drinking and risk of type 2 diabetes. The study indicate that people who drink at least 3 cups of coffee per day more seldom have diabetes and positive effect of coffee is rising along with the amount of the coffee in the diet. It is not clear what mechanism may be responsible for such association but the attention is focus mainly on caffeine, polyphenols, magnesium. Because of the fact that high coffee consumption can cause other adverse health effects coffee should not be treat as a public health strategy to prevent type 2 diabetes, but collected data have scientific character at the moment.

5 Cups Of Coffee A Day For Type 2 Diabetes?

Coffee is one thing that we all love but can’t really decide if it’s good for us or not. Research in the past has shown that coffee and diabetes don’t go well together. However, a new research, funded by American Diabetes Association (ADA), indicates that coffee is good for: Cardiovascular diseases(myocardial infarction, high cholesterol…) Cancer (prostate, breast…) Parkinsons disease According to the research conducted by Marilyn Cornelis, PhD, from NFU School of Medicine: (Of all the foods we consume) coffee has the most potential to prevent type 2 diabetes. (Source: Diabetes Forecast) What is more, WHO has released guidelines for dietary recommendation for Americans for 2015-2020, in which they state that 3-5 cups of coffee is associated with health benefits (including for type 2 diabetes). Seems like both the latest research and even WHO is pro-coffee. I know I’m pro-coffee myself, being an avid coffee drinker and I think it’s great I’m doing something good for myself by having a cup of coffee a day! Let alone 5 cups! You can download the WHO statement here, I’ve copied the section about coffee for you here (be aware what is says about how much sugar and milk you should add to coffee): Let me pour myself another cup of coffee right now (and according to the coffee and diabetes research, you should grab a coffee yourself) because we’re going to see: Why is coffee good for us?

The Truth About Coffee: Is It Good Or Bad For Type 2 Diabetes?

The Truth About Coffee: Is It Good Or Bad For Type 2 Diabetes?

We all love a good cup of joe. But is coffee ok to drink if you’re living with diabetes? The effects of caffeine can work wonders in the morning; this “miracle bean” gives us a jolt of energy to keep us alert and can help you jumpstart your day. The health effects of coffee are often debated. Some claim it’s a superfood that will keep your body in check while others warn about the influence of too much caffeine on the body. So where does this leave coffee and diabetes? Can the bean help with your blood glucose? Or does it have a bad impact on your blood sugar levels? Research has shown that coffee may lower the risks of a number of conditions including strokes, Parkinson’s disease, dementia, and certain cancers. In fact, coffee may even help boost your cerebral power by enhancing your concentration and memory.[1] That’s because coffee beans are actually seeds and contain nutrients that are known to be beneficial to your health. Take polyphenols, for example. Coffee is full of them and they are believed to prevent inflammatory illnesses and contain anticarcinogenic properties.[2] Another beneficial compound is cafestol. Researchers at the Department of Endocrinology and Internal Medicine at Aarhus University Hospital in Denmark reported that cafestol increases insulin secretion. This excess insulin helped reduce fasting glucose levels and improved insulin sensitivity in mice during their research.[3] Another study from Dr. João Sérgio Neves and Prof. Davide Carvalho from the University of Porto in Portugal showed that caffeine may decrease the risk of death among women living with diabetes.[4] In fact, the study showed that one cup of coffee per day may cut the death risk by more than half. But can coffee actually help prevent the onset of diabetes, specifi Continue reading >>

Coffee And Type 2 Diabetes: From Beans To Beta-cells.

Nutr Metab Cardiovasc Dis. 2006 Jan;16(1):69-77. Epub 2005 Dec 13. Coffee and type 2 diabetes: from beans to beta-cells. Department of Nutrition, Harvard School of Public Health, 665 Huntington Avenue, Building 2, Boston, MA 02115, USA. [email protected] Coffee consumption has been associated with improved glucose tolerance and a lower risk of type 2 diabetes in diverse populations in the U.S., Europe, and Japan. This review discusses the strength of the evidence, relevant mechanisms, possible implications, and directions for further research. The finding that higher consumption of decaffeinated coffee was associated with a lower risk of type 2 diabetes suggests that coffee constituents other than caffeine play a role. Coffee is a source of several compounds that improved glucose metabolism in animal studies, including the chlorogenic acids and lignans. Further research on phytochemicals in coffee may lead to the identification of novel mechanisms for effects of diet on the development of type 2 diabetes. In addition, knowledge on effects of coffee components may aid in the development or selection of types of coffee with improved health effects. Longer-term randomized intervention studies that test the effects of coffee consumption on glucose tolerance are warranted. Physical activity and weight management should be the mainstay of public health strategies to prevent type 2 diabetes. For individual choices regarding coffee consumption, potential effects of coffee on various health outcomes should be considered. Continue reading >>

Coffee’s Effect On Diabetes

Coffee’s Effect On Diabetes

Part 1 of 8 Highlights For people without diabetes, coffee may help reduce the risk of developing diabetes. Caffeine has been shown in the short term to increase both glucose and insulin levels. Because of this, people with diabetes should be cautious when consuming coffee. Once sweetener is added to coffee, it removes the benefits of diabetes prevention. It can actually increase your risk of developing diabetes. Coffee was once condemned as being bad for your health. However, there’s growing evidence that it may protect against certain kinds of cancers, liver disease, depression, and Parkinson’s disease. There’s also compelling research that increasing your coffee intake may actually lower your risk for developing type 2 diabetes. This is good news for those of us who can’t face the day until we get in our cup of java. However, for those who already have type 2 diabetes, coffee could have adverse effects. Whether you’re trying to lower your risk, you have diabetes, or you just can’t go without your cup of joe, learn about coffee’s effects on diabetes. Part 2 of 8 According to the Mayo Clinic, diabetes is a disease (or group of diseases) that affects how your body processes blood glucose (sugar). Blood glucose is important because it is what fuels your brain and gives energy to your muscles and tissues. If you have diabetes, that means that you have too much blood glucose circulating in your body and it can cause serious health concerns. There are a number of different factors that can cause diabetes. Chronic diabetes types are type 1 and type 2. Other types include gestational diabetes, which occurs during pregnancy but tends to go away after birth. Another is prediabetes, which means your blood glucose levels are higher than usual but not as high as woul Continue reading >>

Caffeine Risks May Rattle Diabetic People

Caffeine Risks May Rattle Diabetic People

type 2 diabetes -- but it isn't caffeine. Caffeine makes it hard for people with diabetes to control their blood sugar, new studies suggest. In the latest of these studies, Duke University researcher James D. Lane, PhD, and colleagues put continuous blood-sugar monitors on 10 people with type 2 diabetes. All were regular coffee drinkers averaging four cups a day, but they stopped drinking coffee during the experiment. On one day, each patient took a 250 mg caffeine capsule at breakfast and another 250 mg caffeine capsule at lunch. That's roughly the same as having them drink two cups of coffee at each meal. On another day, the same people got placebo pills with no caffeine in them. The result: On the days the patients took caffeine, their blood-sugar 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. "These are clinically significant blood-sugar elevations due to caffeine," Lane tells WebMD. "Caffeine increases blood glucose by as much as oral diabetes medications decrease it. ... It seems the detrimental effects of caffeine are as bad as the beneficial effects of oral diabetes drugs are good." Lane warns against reading too much into this small, 10-patient study. But he says it does show that caffeine has real effects on the everyday lives of people with diabetes. "For people with diabetes, drinking coffee or consuming caffeine in other beverages may make it harder for them to control their glucose," he says. (If you have diabetes, how much caffeine do you consume on a regular basis? Talk with others on WebMD's Type 2 Diabetes Support Group message board.) Several studies have found that coffee drinkers -- especially those who drink a lot of coffee -- have a lower risk of diabe Continue reading >>

Can A Type 2 Diabetic Drink Coffee?

Can A Type 2 Diabetic Drink Coffee?

The American Diabetes Association identifies coffee as an acceptable beverage for people with diabetes. However, coffee's impact on blood sugars can vary. According to a review published in the February 2014 issue of "Diabetes Care," the risk of developing type 2 diabetes (T2DM) decreases with coffee consumption. However coffee and the additives in coffee drinks can influence blood sugar control in those who already have diabetes. Testing blood sugars may be the best way to learn the body's response to these beverages. Video of the Day A small study published in the May 2011 issue of "American Journal of Clinical Nutrition" reviewed the blood glucose effects of coffee when consumed with a meal, and found that caffeinated coffee caused more insulin resistance and higher post-meal blood sugars compared to decaffeinated coffee. An individual with insulin resistance will require more insulin to lower blood sugar compared to someone whose body uses insulin efficiently. Duke University research published in the February 2008 issue of "Diabetes Care" studied habitual coffee drinkers who had T2DM, testing their glucose levels after ingestion of caffeine supplements equivalent to four cups of coffee. Compared to a placebo, the caffeine supplements caused higher post-meal blood sugars. While the mechanism was unclear, the researchers suggested caffeine may worsen insulin resistance or affect glucose by increasing the production of stress hormones. Decaffeinated coffee may also have an impact on blood sugar levels. Researchers who studied these effects on a small group of healthy young men published their findings in the February 2010 issue of "Diabetes Care." Within 60 minutes of consumption, decaffeinated coffee raised blood glucose more than a placebo, but less than caffeinated Continue reading >>

Can Drinking Coffee Help Prevent Type 2 Diabetes?

Can Drinking Coffee Help Prevent Type 2 Diabetes?

If you begin your day with a steaming cup of joe, you could be protecting your health along with jump-starting your morning. That's because research shows coffee may reduce the risk of type 2 diabetes. But how much do you need to drink to reap the potential benefits? What the Research Says Researchers at the Harvard School of Public Health and Brigham and Women’s Hospital conducted one of the biggest long-term studies on the relationship between coffee and type 2 diabetes in 2004. They found that the more coffee people drank, the greater the protection against diabetes. The study followed 41,934 men for 12 years and 84,276 women for 18 years. At the beginning of the study, the participants did not have type 2 diabetes. They were asked to answer questions about their coffee-drinking habits (regular and decaffeinated) every two to four years. During that time, 1,333 new cases of type 2 diabetes were reported among the men and 4,085 cases were reported among the women. Men who reported drinking more than six cups of regular, caffeinated coffee per day cut their risk of developing type 2 diabetes in half when compared to nondrinkers of coffee. Women who reported drinking that much cut their risk by about 30 percent. Decaffeinated coffee also showed benefits, but the results were weaker. Another study suggested that the more coffee you drink, the better. In the same year as the Harvard study, researchers in Finland, the country with the highest per capita coffee consumption in the world, found that the risk of developing diabetes appeared significantly lower in people who drank at least 10 cups a day. People who drank fewer cups of coffee had the same risk as nondrinkers. Coffee consumption may also help people who are already living with type 2 diabetes, according to the Continue reading >>

Does Caffeine Affect Blood Sugar?

Does Caffeine Affect Blood Sugar?

The average U.S. adult consumes about two 8-ounce cups (474 milliliters) of coffee a day, which can contain around 280 milligrams of caffeine. For most young, healthy adults, caffeine doesn't appear to noticeably affect blood sugar (glucose) levels, and consumption up to 400 milligrams a day appears to be safe. Some studies suggest that drinking coffee, caffeinated and decaffeinated, may actually reduce your risk of developing diabetes. If you already have diabetes, however, the impact of caffeine on insulin action may be associated with higher or lower blood sugar levels. For some people with diabetes, about 200 milligrams of caffeine — or the equivalent of one to two 8-ounce cups (237 to 474 milliliters) of plain, brewed coffee — may cause this effect. Caffeine affects every person differently. If you have diabetes or you're struggling to control your blood sugar levels, limiting the amount of caffeine in your diet may provide a benefit.
