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. [20] 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 >>

Nine Reasons Your Blood Sugar Can Go Up
Diet is the primary way diabetics control the level of sugar in our blood. Doing so, however, is not simple. Here are 9 reasons why blood glucose levels can increase. In order to prevent type 2 diabetes destroying our bodies, we diabetics need to control the glucose floating around in our bloodstream. Many of us are succeeding in doing so by the diets we eat. Sometimes however our diets do not work very well and our blood sugar readings rise for reasons we cannot fathom easily. This may be because of a lack of knowledge of how certain foods or other things can affect the level of glucose in our blood. Here are 9 typical reasons why our blood sugar can rise unexpectedly: caffeine sugar-free food fat-heavy food bagels sports drinks dried fruits a bad cold or flu stress steroids and diuretics Caffeine Drinking coffee, black tea, green tea, and energy drinks, all containing caffeine, has been associated with a small, but detectable rise in blood sugar levels, particularly after meals. This can happen, even if you drink black coffee with zero calories. Two to three cups a day (250mg of caffeine) can have this effect. In one experiment conducted on 10 people with type 2 diabetes, the subjects were given capsules of caffeine (the equivalent of four cups), rather than coffee. This increased their blood glucose levels by up to 8%. But how caffeine raises blood sugar has not been figured out yet. The irony is that coffee, both caffeinated and decaffeinated, has other components that reduce blood glucose, and coffee has been associated with a reduced risk of developing type 2 diabetes. Each person reacts differently to drinks containing caffeine, so it’s best to track your own responses to this little kicker and figure out for yourself whether the effect of caffeine on your bloo Continue reading >>

Does Drinking Coffee Release Insulin?
Coffee drinkers comprise 54 percent of the adult population of the United States, with the average coffee drinker consuming about 3 cups per day, according to Harvard Health Publications. Scientists have studied the health effects of this popular beverage; however, experts remain divided on coffee's effects on insulin and blood sugar levels. Insulin levels did not change after drinking a double serving, or shot, of espresso coffee in participants of a study published in the September 2012 issue of the journal "Metabolism." One hour after consuming either caffeinated or decaffeinated espresso, volunteers underwent a glucose tolerance test, in which they consumed 75 grams of glucose and had blood sugar levels measured at certain intervals for the following two hours. Researchers noted that there was also no change in insulin sensitivity in response to the single dose of double espresso. Diabetes Risk Daily coffee consumption decreases risk for Type 2 diabetes, according to a study published in the May 2012 issue of the journal "Current Diabetes Reviews." The review of previously published research found that participants who drank 4 to 6 cups per day showed lower rates of Type 2 diabetes than those who drank less than 2 cups per day. Filtered and decaffeinated coffees offer greater advantages over boiled and caffeinated coffees, note researchers. Individual Response Insulin levels did not change in response to either caffeinated or decaffeinated coffee in a study published in the November 2005 issue of the "Journal of Nutrition and Metabolism." Individual variations in insulin metabolism made a correlation between coffee consumption and insulin levels difficult to discern, according to researchers. Coffee consumption of 5 cups per day resulted in lower glucose levels two 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 >>

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? What does other research about coffee and diabetes suggest How much sugar and milk I personally add to my coffee? I’ll reveal my own easy recipe for diabetes-friendly coffee – I’m drinking one right now! In short, do coffee and diabetes go hand in hand together? Let’s find out: Coffee and Diabetes – An Age Old Question I don’t really know anybody that wouldn’t l Continue reading >>

Coffee And Insulin – How Caffeine Intake Affects Weight Loss
How do you start your morning off? Mine begins with a steaming hot cup of my favorite coffee. The black nectar also accompanies my workouts, my busy evenings when I have to work late, my headache treatments, and even my post-workout recovery shakes. I know I am not alone in my love for coffee. In the past 6 decades, researchers have conducted more than 21,000 studies on coffee’s signature stimulant, caffeine. That’s an average of one new study a day! If there is a disease then chances are that someone has already tried to link the effects of caffeine to it. Cancers, heart disease, infertility, brain malfunction, asthma, migraines, gallbladder disease, attention-deficit hyperactivity disorder, high and low blood pressure, diabetes and obesity have all been on the list. You have probably been warned to stay away from drinking too much coffee and given tips on how to gradually get off the java, but is it worth the effort to cut back and even quit? Hold onto your mug and keep reading! Calorie-Free Insulin SurgesThe problems regarding coffee’s impact on blood sugar and insulin levels have been brewing for a while and the arguments are steaming on both sides. Short-term metabolic studies have shown that caffeine intake can acutely lower insulin sensitivity and sometimes even raise blood sugar levels. One study published in “Diabetes Care” found that consuming 70 grams of coffee grounds for 4 weeks increased fasting insulin concentrations in 40 healthy volunteers without substantially affecting fasting glucose concentrations. The researchers suggested that such results reflect decreased insulin sensitivity from high caffeine intake. What’s worse is that after just 5 days of regular supplementation, the body’s blood glucose control system may become tolerant to th Continue reading >>

Does The Caffeine In Coffee All Turn To Sugar?
Simply put: caffeine does not turn into sugar. It can, however, raise the blood sugar levels inside your body. This is not because it contains sugar, but because of how it affects substances inside your body, primarily insulin. Insulin causes metabolism of food into blood sugar, which fuels your cells. Insulin is also associated with depositing excess energy as fat. Basics: Caffeine is a chemical compound found in foods, as is sugar. Blood sugar, however, is found in your bloodstream. Blood sugar rises or lowers as a result of many things, including the amount of sugar you've eaten, but also the amount of insulin your body has released, which affects blood glucose levels. Caffeine can affect insulin action and, therefore, blood sugar. Effects: Drinking coffee with meals has been shown to increase both insulin resistance and glucose levels dramatically. In the November 5, 2009, issue of "British Journal of Nutrition," Terry Graham, M.D., and colleagues found that in healthy young males, caffeinated coffee consumed with carbohydrate caused insulin insensitivity. They concluded that caffeine affects glycemic control. Warning: If you have diabetes, the effects of caffeine on your blood sugar levels may be worse. Duke researchers led by James D. Lane, Ph.D., reported in the February 2009 issue of "Diabetes Care" that drinking the equivalent of two 8-oz. cups of coffee with both breakfast and lunch increased daytime blood glucose levels plus glucose response immediately after eating. The researchers warn that repeated episodes of such elevation could jeopardize blood sugar control. Speculation: These recent studies conflict with past studies about coffee, which have consistently found that coffee drinkers have a lower risk of developing Type 2 diabetes. Harvard researcher Rob Continue reading >>

Caffeine And Type 1 Diabetes
Have you ever noticed a difference in your blood sugar after drinking a big cup of coffee or tea? According to the Mayo Clinic, caffeine can indeed have an affect on your blood glucose levels causing lower or higher fluctuations, so limited consumption is recommended for better control. Another study published by the ADA (2005) suggests that people with Type 1 or Type 2 diabetes can reduce their risk of hypoglycemia during the night by having a small to moderate amount of caffeine before bed. Some people also claim that symptoms of hypoglycemia become more noticeable when incorporating caffeine into their diet. The effects of caffeine on each person are varied though with the added factor of tolerance to the stimulant can build up as quantity increases. While some people claim that they see a noticeable difference in their BG levels when they drink caffeine, others say that they don’t have any issues incorporating caffeine with food. Let’s explore some variables that could contribute to the shift in BG levels in relation to caffeine consumption. Side effects Certain common side effects of caffeine consumption may often explain shifts in BG levels. Lack of sleep Not enough sleep has proven to contribute to insulin resistance in the body for people with Type 1. Too much caffeine could certainly contribute to insomnia, especially since caffeine tolerance decreases as we grow older. Elevated heart rate / “the jitters” Two common effects if too much caffeine is in the system, or if the body is not accustomed to it. These are also symptoms of hypoglycemia, which might cause someone with Type 1 to check their BG levels more frequently if mistaking the symptoms for a low. Heartburn / Upset stomach / Dehydration Some people are less tolerant to coffee and other caffeinat Continue reading >>

Does Caffeine Cause Blood Sugar Changes?
The first thing I did after reading the new study that caffeine can increase our blood glucose level was to switch to drinking green tea. The second thing I did was to switch again — this time to decaffeinated green tea. I overreacted. Several years ago I had switched from coffee to Darjeeling tea, which has about half the caffeine per cup. While green tea has even less, I don’t like it much and only drink it rarely. I disliked the decaffeinated green tea so much that I threw out the package after taking the first sip. Now, I’m almost entirely back to Darjeeling tea. People call it a black tea, although it is light-colored and is technically more oolong than black and is therefore lower in caffeine than true black teas. While I control my blood glucose level, I’m not a purist. I have to enjoy everything that I eat or drink. While my diet includes no starch, sugar (no sucrose or high-fructose corn syrup), salt, or alcohol, except occassionally when I eat out, I don’t miss any part of this standard American, or SAD, diet. My recent A1C result was 5.3 percent. Caffeine may well raise my blood glucose level. But after carefully reading the new study, I doubt it. The new study is a review in the April 7 issue of the Journal of Caffeine Research by James D. Lane, associate research professor in the department of psychiatry and behavioral sciences at Duke University Medical Center. Dr. Lane sent me the full-text of the study, which is now free online. Dr. Lane reviewed 17 studies that showed that caffeine increased insulin resistance or impaired glucose tolerance of people who don’t have diabetes. Using accepted study design — double-blind and placebo-controlled — and moderate doses of caffeine equivalent to two or three cups of brewed coffee, these studies con Continue reading >>

Decaffeinated Coffee And Glucose Metabolism In Young Men
Go to: RESEARCH DESIGN AND METHODS Eleven healthy male nonsmokers signed an informed consent and participated. The following participation requirements were started 1 week prior to the first lab visit: keep diet, exercise, and alcohol intake stable; no caffeinated drinks, foods, or medications; no smoking; and no alcohol or exercise during the 48 h prior to each visit. There were four visits separated by at least a week. Participants ingested one of four beverages assigned by researchers in a single-blinded randomized fashion at a temperature of 43–49°C (caffeinated coffee, decaffeinated coffee, caffeine in warm water, or warm water [placebo]). An oral glucose tolerance test (OGTT) was initiated 1 h later (t = 0 min) with ingestion of 75 g of glucose in water. Blood was drawn at time −90, −60, 0, 10, 30, 60, 90, and 120 min. Participants drank 500–600 ml of drip-filtered ground coffee (Chock Full O'Nuts Original; Massimo Zanetti Beverage, Portsmouth, VA). The recipe was eight cups of water with 40 g of grounds for caffeinated and 57 g of grounds for decaffeinated coffee. For the caffeine and hot water (placebo) beverages, we ran eight cups of water through the machine with filter paper without coffee grounds. For the caffeine beverage, we added food-grade caffeine powder (Spectrum Chemical Manufacturing, Gardena, CA). The volume ingested was the same for each beverage and differed by participant to yield 6 mg caffeine/kg of body wt in the caffeine and caffeinated coffee beverage. The caffeine content of the caffeinated coffee was measured as 0.73 mg/ml coffee, by high-performance liquid chromatography. Glucose was assayed in plasma using the oxygen rate method (Beckman Glucose Analyzer 2; Beckman, Brea, CA). Insulin was assayed in plasma (human-specific radioim Continue reading >>

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 >>

Pregnancy And Diabetes
Is coffee inherently a dangerous substance, and should caffeine be stripped from our diets? There are some who say yes, and others who ignore all that. We are true coffee addicts and would be hard-pressed to give it up, but we are always interested in new data on caffeine. So we couldn't avoid the two health alerts in the last week about coffee. The first is about diabetes and the other is a warning to pregnant women. UK researchers announced results of a study that shows coffee may raise blood sugar in diabetics. The effect that they found was especially pronounced in the evenings. The key element of course is the caffeine; does cutting caffeine help control blood sugar levels? The researchers feel that more research is necessary to say conclusively, but there may be a correlation. In other caffeine-related news, a study was released a week ago that ties increased rates of miscarriage and pregnancy issues to caffeine consumption. It is fairly standard in the West for pregnant women to completely go off caffeine, or to stick to decaf coffee, which has a small amount of caffeine. This study bolsters that accepted wisdom. Even though the data is not completely unambiguous, it supports again that in coffee and caffeine, like most other things, moderation is key. We're not giving up our coffee any time soon, but we did switch from 2 or 3 cups of drip brew coffee to one small, rich cup of French press in the mornings. Continue reading >>

How Does Coffee Affect My Diabetes And Can I Still Drink It?
Diabetes and Coffee – How Does It Affect You? There are many conflicting opinions about diabetes and coffee, and how drinking coffee can relate both positively and negatively to diabetes. Various studies demonstrate coffee may prevent individuals from developing diabetes, while other studies seem to prove coffee can negatively impact blood glucose levels in those who already have diabetes. The Theory Behind Coffee Reducing the Risk of Type 2 Diabetes Let’s 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 Age Blood pressure Occupational Commuting Smoking Leisure time physical activity Alcohol Tea drinking 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 Theory Behind Coffee Increasing Blood Sugar and Insulin Levels Research seems to show in those with preexisting diabetes and those without any diagnosis; coffee can raise blood sugars and affect insulin levels. One study demonstrated that a single serving of coffee, containing 100 mg of caffeine, negatively affected blood sugar control in healthy but overweight men. Other studies showed that consuming caffeinated coffee impaired blood sugar regulation and insulin sensitivity after meals. However, this does not happen with decaf co Continue reading >>

The Mystery Of Coffee And Diabetes
Is coffee good or bad for diabetes? Some studies show that coffee is protective, while others say it’s harmful. Some say decaf is better; others say it’s worse. Let’s try to sort this out. For years, various studies have reported that coffee drinkers are less likely to develop Type 2 diabetes. A recent UCLA study found that “women who drink at least four cups of coffee a day are less than half as likely to develop diabetes as non-coffee drinkers.” Lead scientist Simin Liu said that coffee may improve the body’s tolerance to glucose by increasing metabolism or lowering insulin resistance. In 2008, Diabetes Self-Management blogger Amy Campbell reported on several other studies showing benefits for coffee. A study published in Diabetes Care in 2006 followed about 900 adults, roughly 300 of whom had prediabetes, for eight years. The people who drank caffeinated coffee had a 60% lower risk of getting diabetes than those who didn’t drink coffee. Another Diabetes Care study published the same year looked at more than 88,000 women in the Nurses’ Health Study II. It found that women who drank two or more cups of coffee daily had a lower risk (slightly more than half the risk) of getting diabetes than those who drank just one cup of coffee daily, or no coffee at all. And it didn’t matter whether the coffee was regular or decaf. So right there you have a disagreement about caffeine. Meanwhile, other studies have shown that coffee, or the caffeine in coffee, raises after-meal (postprandial) blood glucose levels up to 20% in people with diabetes. These studies have not been large but have received a lot of attention. In the most-reported study, from Duke University, ten subjects, all with diabetes, were tested — given either caffeine capsules or a placebo (inacti Continue reading >>

Do Coffee Drinkers Die Young Or Live Long?
Many get caught in the sugar, nicotine, caffeine trap, thinking this combination is good for energy. But this combination feeds increasing fatigue, anxiety and weight gain. In my own research we surveyed over 55,000 people and found that the two foods that most predict fatigue and stress are caffeinated drinks and sugary foods, both addictive substances. Many people become hooked on caffeine and sugar to keep going, gaining weight and losing health as a result. But what are the long-term consequences? Do coffee drinkers live longer or die young? A study following the fate of almost 400,000 people has found that, overall, coffee drinkers are more likely to die younger. But is that a result of the coffee or associated habits? When the researchers adjusted for smoking, the risk of death actually reversed. Coffee drinkers tended to have a slightly lower risk of death, although the decreased risk didn’t consistently become greater the more coffee was drunk. Slightly less risk were observed for deaths due to heart disease, respiratory disease, stroke, diabetes, and infections, but not for deaths due to cancer. Coffee, diabetes and weight However, as far as diabetes is concerned you may be pleased to know that there is now enough evidence to show that coffee actually decreases risk. In fact there have been eighteen studies involving almost half a million people that do show overall that coffee, decaffeinated coffee and tea do slightly reduce risk of diabetes. There are various theories as to why this might be since having a lot of caffeine itself isn’t good for your health. Both tea and coffee are high in antioxidants which is a potential benefit. Two recent studies have shown that coffee doesn’t cause the release of insulin, and may even reduce insulin resistance. Inter Continue reading >>
