Caffeine Blocks Insulin A survey reported in JAMA showed that drinking coffee reduces risk for developing type II diabetes, but other studies suggest that once you have diabetes, drinking coffee may be unwise. A report from the Netherlands showed that caffeine in coffee raises blood sugar levels. Diabetics suffer blindness, deafness, heart attacks, strokes, kidney failure, burning foot syndrome and many other serious side effects, and all are caused by a high-rise in blood sugar after meals. Anything that raises blood sugar levels too high increases cell damage in diabetics. This study shows that caffeine raises blood sugar levels by causing the body to put out large amounts of adrenalin that makes cells less responsive to insulin. When caffeine was removed from the coffee, blood sugar levels did not rise higher than normal. On the basis of this study, diabetics should drink decaffeinated coffee, rather than one with caffeine, in addition to severely restricting sugar-added foods, bakery products, pastas, fruit juices and they should eat root vegetables and fruits only with meals. Canadian researchers writing in Diabetes Care showed that caffeine significantly reduced insulin sensitivity. In another study in the same journal, scientists from Duke University Medical Center reported that drinking coffee could upset a diabetic’s ability to metabolize sugar. Blood sugar levels are supposed to rise after you eat. To keep your blood sugar levels from rising too high, your pancreas releases insulin. The researchers found that taking caffeine causes blood sugar and insulin levels to rise even higher after meals. If your blood sugar rises too high, sugar sticks to cells. Once sugar is stuck on a cell membrane, it cannot be released and is converted to a poison called sorbitol Continue reading >>
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 >>
Prediabetes? The Coffee-health Connection
New research has shown—yet again—that drinking coffee can reduce your type 2 diabetes risk. The study, in nearly 1,500 Greek adults followed for a decade, found that people who downed the equivalent of 2.5 to 3 cups of brewed coffee daily had half the risk of developing type 2 diabetes. And people who drank about 1.5 cups of joe a day cut their risk by about 30%. “Apparently healthy individuals with no history of cardiovascular disease may benefit from daily consumption of this amount of coffee,” one of the study’s authors, Efi Koloverou, MmedSci, a clinical dietitian and doctoral candidate at Harokopio University in Athens, told DiabeticLifestyle in an e-mail interview. The findings were published July 1, 2015 in the European Journal of Clinical Nutrition. There were too few decaf drinkers in the new study to draw conclusions about whether caffeine-free brew would have the same benefits. But there’s strong evidence from other research that decaf has similar protective effects, according to Mary Ann Johnson, PhD, the Flatt Professor in Foods and Nutrition at the University of Georgia in Athens and a national spokesperson for the American Society for Nutrition. Researchers suspect that a substance in the coffee bean itself is what helps to lower inflammation in the body. This in turn can reduce overall risk for developing type 2 diabetes. Johnson points to a 2014 meta-analysis (a study in which the results of several smaller studies are pooled and analyzed together) which included 28 studies and 1.1 million people and found both coffee and decaf coffee drinkers had a reduced likelihood of developing type 2 diabetes. And the more a person drank, the lower their risk. Java drinkers got more good news earlier this year, when the 2015 Dietary Guidelines Advisory Continue reading >>
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. Continue reading >>
Coffee And Diabetes
Tweet The effect of coffee on diabetes, when presented in the media can often be confusing. News stories can in the same week tout the benefits coffee can have on diabetes and shoot down coffee as being unhelpful for blood sugar levels. This doesn’t mean the articles are contradictory though. Put slightly more simply, coffee contains different chemicals, some of which have beneficial effects whereas others can have a less beneficial effect, such as caffeine which can impair insulin in the short term. Caffeine and blood sugar levels Regular high caffeine consumption, over a 4 week period, has been shown to impair insulin sensitivity in people with type 2 diabetes.  Whilst 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. Benefits of coffee Coffee has been shown to lower risks of the following conditions: Coffee contains polyphenols, which are a molecule that anti-oxidant properties which are widely believed to help prevent inflammatory illnesses, such as type 2 diabetes, and anticarcinogenic (anti-cancer) properties. As well as polyphenols, coffee contains the mineral magnesium and chromium. Greater magnesium intake has been linked with lower rates of type 2 diabetes. The blend of these nutrients can be helpful for improving insulin sensitivity, which may help to offset the opposite effects of caffeine. Coffee and prevention of diabetes Coffee and its effect on risks of developing type 2 diabetes have been studied a number of times and has indicated a notably lower risk of type 2 diabetes being associated with coffee drinkers. A 2009 study of 40,000 participants noted that consumptio Continue reading >>
Caffeine Raises Blood Sugar Levels In Type 2 Diabetics
It may come as quite a shock to those type 2 diabetics who regularly consume caffeine to hear that studies are now showing that caffeine raises blood sugar levels in type 2 diabetics. Are you trying to maintain healthy blood sugar levels naturally? Sugar Crush products are all natural and organic dietary supplements backed by clinical research to manage your blood sugar levels. Click here to read more. I’m a regular diet coke drinker and I thought that because there is no sugar in diet coke it was safe for me to drink regularly…I was wrong. The American Diabetes Association announced the findings of a Duke University study which showed that caffeine raised the blood glucose levels of type 2 diabetics throughout the day and especially after meals. But I thought caffeine was ok for diabetics? Previous studies on the link between caffeine and diabetes had shown that caffeine consumption lowered the risk of type 2 diabetes. Those who drank the most caffeine were the least likely to develop type 2 diabetes. It was these finding that may have lead to the misconception that caffeine had no ill effect on diabetics. What the Duke University study is now showing is that in people who have type 2 diabetes, caffeine raised their blood sugar levels throughout the day. So even if they drank caffeine in the morning it had an effect on their blood sugar level throughout the entire day making it difficult to keep it under control. So what is suggested? Well, if you are a type 2 diabetic such as myself, and you are finding it difficult to keep your blood glucose levels in the normal range you may want to examine the amount of caffeine you are consuming. Like I said, I am a diet coke drinker. This is the source of any caffeine that I consume. I have been having a hard time controlling Continue reading >>
The Best And Worst Drinks For Diabetics
Drinks for Diabetics iStock When you have diabetes, choosing the right drink isn’t always simple. And recent studies may only add to the confusion. Is coffee helpful or harmful to insulin resistance? Does zero-calorie diet soda cause weight gain? We reviewed the research and then asked three top registered dietitians, who are also certified diabetes educators, what they tell their clients about seven everyday drinks. Here’s what to know before you sip. Drink More: Water iStock Could a few refreshing glasses of water assist with blood sugar control? A recent study in the journal Diabetes Care suggests so: The researchers found that people who drank 16 ounces or less of water a day (two cups’ worth) were 30 percent more likely to have high blood sugar than those who drank more than that daily. The connection seems to be a hormone called vasopressin, which helps the body regulate hydration. Vasopressin levels increase when a person is dehydrated, which prompts the liver to produce more blood sugar. How much: Experts recommend six to nine 8-ounce glasses of water per day for women and slightly more for men. You’ll get some of this precious fluid from fruit and vegetables and other fluids, but not all of it. “If you’re not in the water habit, have a glass before each meal,” recommends Constance Brown-Riggs, MSEd, RD, CDE, CDN, a spokesperson for the Academy of Nutrition and Dietetics and author of The African American Guide to Living Well with Diabetes. “After a few weeks, add a glass at meals too.” Drink More: Milk iStock Moo juice isn’t just a kids’ drink. It provides the calcium, magnesium, potassium, and vitamin D your body needs for many essential functions. Plus, research shows it may also boost weight loss. In one study of 322 people trying to sl Continue reading >>
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 >>
How Does Coffee Affect Diabetes?
With diabetes, diet is of the utmost concern. What people with diabetes eat and drink directly affects their blood glucose levels. We often concentrate on food, but what people drink is just as important. For many people, the only way to get the day started is with a cup of coffee. Thankfully, recent studies have shown that drinking coffee may actually reduce the risk of getting diabetes. But what about for those who already have diabetes? Is coffee, or the caffeine in coffee, a problem for those with diabetes? Two 8-ounce cups of coffee contain about 280 milligrams of caffeine. For most young healthy adults, caffeine does not seem to make blood sugar levels higher. Even consuming up to 400 milligrams per day appears to be safe for most people. This article will take a closer look at caffeine and some of the research that has been done in this area. Diabetes and caffeine According to the American Diabetes Association in 2012, 29.1 million Americans or 9.3 percent of the population had diabetes. About 8.1 million of the 29.1 million were undiagnosed. The World Health Organization reported that the number of people with diabetes worldwide in 2014 was 422 million. Diabetes affects how the body uses sugar (glucose). The body needs glucose because it is an important energy source for certain cells and is the brain's main source of fuel. Glucose in the body comes from food and drink as well as being made by the liver. Insulin is a naturally occurring hormone in the body and helps the body to absorb glucose. People who have diabetes have too much glucose in their blood, which can cause serious health problems. Diabetes can occur due to either the pancreas not producing no or not enough insulin or the body being unable to use insulin effectively. Type 2 is the most common type Continue reading >>
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 >>
Caffeine Reduces Mortality Risk In Women With Diabetes
Drinking at least 1 cup of coffee per day could reduce the risk of all-cause mortality by 51%. There is growing evidence that caffeine can be beneficial when consumed in moderate amounts. A new study presented at the European Association for the Study of Diabetes suggests that coffee may have even more health benefits than previously known. The authors report that drinking 1 cup of coffee per day could reduce mortality rate more than 50% for women with diabetes, which is a significant reduction. In the study, the authors analyzed the link between caffeine consumption and mortality among 1568 women and 1484 men with diabetes. Patients self-reported caffeine intake, including the source of caffeine. The authors adjusted for potentially confounding factors, such as body mass index, income, education, alcohol intake, smoking, hypertension, and time since diagnosis. Over the 11-year study period, the researchers reported 618 deaths; however, there was no link between caffeine and all-cause mortality, cardiovascular mortality, or cancer-related mortality in men, according to the study. Interestingly, women who consumed up to 100-mg of caffeine—or 1 cup of coffee—had a 51% lower risk of premature death compared with women who abstained from caffeine. Women who consumed 100-mg to 200-mg of caffeine had a 57% lower risk of mortality than those who did not consume caffeine, while women who consumed more than 200-mg had a 66% lower mortality rate, suggesting a dose-dependent relationship, according to the study. "Our study showed a dose-dependent protective effect of caffeine consumption on all-cause mortality among women," the authors wrote. The authors also found that women who got their caffeine from tea also had lower rates of mortality. "Women who consumed more caffeine f Continue reading >>
How Does Coffee Affect Blood Sugar And Diabetes?
Type 2 diabetes is a massive health problem worldwide. About 29 million people, or 9% of all US adults, had type 2 diabetes in the year 2012 (1). Interestingly, long-term studies have linked coffee drinking with a reduced risk of type 2 diabetes (2, 3). Yet, oddly enough, many short-term studies have shown that coffee and caffeine can raise blood sugar and insulin levels (4, 5, 6). Why this happens is not fully known, but there are several theories. This article examines the short-term and long-term effects of coffee on blood sugar and diabetes. The health benefits of drinking coffee are well-documented. In observational studies, coffee is linked to reduced blood sugar and insulin levels, which are major risk factors for type 2 diabetes (7). Furthermore, consuming regular or decaf coffee on a regular basis is linked to a 23–50% lower risk of developing type 2 diabetes (3, 8, 9, 10, 11). Studies have also shown that each daily cup of coffee you consume may reduce this risk by 4–8% (3, 8). Additionally, people who drink 4–6 cups of coffee each day have a lower risk of type 2 diabetes than people who drink less than 2 cups each day (12). Regular coffee drinking has been linked to a 23–50% lower risk of type 2 diabetes. Each daily cup is linked to a 4-8% lower risk. A major paradox exists between the long-term and short-term effects of coffee. Short-term studies have linked caffeine and coffee consumption with increased blood sugar levels and insulin resistance (13). A recent study showed that a single serving of coffee, containing 100 mg of caffeine, can negatively affect blood sugar control in healthy but overweight men (14). Other short-term studies -- both in healthy individuals and in type 2 diabetics -- show that consuming caffeinated coffee impaired blood sug Continue reading >>
Caffeine Linked To Lower Risk Of Death In Women With Diabetes
Women with diabetes who regularly drink caffeinated coffee or tea may live longer than those who don't consume caffeine at all, according to new research being presented at this year's European Association for the Study of Diabetes (EASD) Annual Meeting in Lisbon, Portugal (11-15 September). No association was found for men with diabetes. This observational study found that the more caffeine women consumed the lower their risk of dying compared to those who never consumed caffeine. Importantly, the protective effect depended on the source of the caffeine: higher levels of caffeine consumption from coffee were associated with a reduced risk of death from any cause, particularly from cardiovascular disease; while women who consumed more caffeine from tea were less likely to die from cancer. More than 80% of the world's adult population consume caffeine daily, mostly from coffee and tea. Average daily coffee consumption is between 100 mg and 300 mg per day, depending on age and country. The mean in the USA, for example, is 165 mg per day. Many studies have shown a beneficial effect of drinking coffee on the risk of death from all causes in the general population, but little is known about the role of caffeine on mortality in people with diabetes. In this study, a group of medical residents from various institutions in Portugal (Dr. João Sérgio Neves and Professor Davide Carvalho from the University of Porto and colleagues across Portugal examined the association between varying levels of caffeine intake and mortality in over 3,000 men and women with diabetes from the 1999 to 2010 National Health Nutrition Examination Survey (NHANES)--a study tracking the health and nutritional status of a nationally representative sample of adults in the USA since 1971. Participants repo Continue reading >>
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 >>
