Coffee And Heart Health
Studies suggest coffee helps protect our hearts, rather than harm them. Let’s be honest—who doesn’t enjoy a cup of coffee (or two) in the morning, afternoon, or somewhere in between? Each day, Americans drink more than 400 million cups of coffee, and for regular coffee drinkers, kicking the habit can be tough. But according to a recent study published in the Journal of the American College of Cardiology, we shouldn’t feel guilty about our coffee drinking habits as it may help protect our hearts. This paper reviewed recent research on the subject, looking into the impact of coffee consumption on a number of markers of heart health like blood pressure, cholesterol, and blood sugar. And here’s what they found: Blood pressure: Drinking coffee—as much as six cups a day—does not increase blood pressure levels long-term. Blood sugar: The antioxidants in coffee (caffeinated and decaf) aid in blood sugar control, reducing risk for type 2 diabetes. Even drinking a small amount of coffee each day can reduce risk for type 2 diabetes, and drinking as many as six or more cups a day may further reduce risk. Cholesterol: Coffee contains a cholesterol-raising compound called diterpenes, but the concentration of this compound depends on how the coffee is prepared. Boiled coffee has a higher concentration of diterpenes, which can increase total cholesterol and “bad” cholesterol levels. Filtered coffee, however, has no effect on cholesterol levels. Risk for irregular heartbeat: Despite initial concerns that caffeine may increase risk for an irregular heartbeat, called arrhythmia, drinking coffee appears to have no impact on arrhythmia risk. In fact, drinking coffee on a daily basis may actually reduce arrhythmia risk. Cardiovascular risk: Moderate coffee consumption (1-2 Continue reading >>
Coffee May Lower Risk Of Type 2 Diabetes
People who drank three to four cups of coffee per day had an approximate 25% lower risk of diabetes than people who drank no coffee Nearly two decades into the coffee renaissance in North America, it is reassuring to find that this popular beverage might protect us against an alarmingly common contemporary malady—type 2 diabetes, a disease affecting at least 171 million people worldwide and causing enormous economic, health, and social costs. A new analysis of previous research concluded that drinking coffee, as well as decaffeinated coffee and black tea, was associated with a reduced risk of developing type 2 diabetes. A cup of protection The report on coffee, published in the Archives of Internal Medicine, was based on the results from 18 studies, which included a total of nearly 458,000 people. A combined analysis of the findings identified a significant relationship between coffee-drinking and reduced risk of diabetes: People who drank three to four cups of coffee per day had an approximate 25% lower risk of diabetes than people who drank no coffee or fewer than two cups per day. Every additional cup of coffee per day was associated with an additional 7% reduction in risk. Six studies with a total of 226,000 participants included data on decaffeinated coffee consumption, and seven studies with 287,000 participants included data on black tea. Protective effects were identified for both: Decaf drinkers taking 3 to 4 cups of decaf per day had a 36% lower risk of diabetes compared with people who did not drink any. Tea drinkers consuming 3 to 4 cups of tea per day had an 18% lower risk of diabetes compared to non-tea drinkers. Caffeine: virtue or vice? Health concerns about coffee drinking are most often related to its caffeine content. Caffeine can temporarily increa 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?

Caffeinated And Decaffeinated Coffee Consumption And Risk Of Type 2 Diabetes: A Systematic Review And Dose-response Meta-analysis.
High consumption of caffeinated or decaffeinated coffee may reduce type 2 diabetes risk. The objective of this research work was to determine the correlation between the consumption of caffeinated and decaffeinated coffee and the incidence of type 2 diabetes. Researchers analyzed data obtained from 28 studies that examined 1,109,272 subjects and 45,335 type 2 diabetes cases. They found out that subjects who drank between 1-6 cups of caffeinated or decaffeinated coffee per day had slim chances of developing type 2 diabetes. The findings of this review reveal that high intake of caffeinated or decaffeinated coffee may decrease an individual's susceptibility to the development of type 2 diabetes. Note: This is another study that seems to indicate that caffeine does not promote diabetes. Although other studies do indicate that caffeine makes it harder to keep blood sugar under control.

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 >>

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 >>
Benefits Of Decaf Coffee
Almost everyone loves a strong cup of coffee in the morning. It's warming, it's comforting and it's invigorating. And when you're having a hard day it's one of the best pick me ups and one of the best ways to feel ready to go again. But is it good for you? Well the answer is yes and no. Coffee is good for you in a number of ways and if you drink coffee then you will benefit from antioxidants and other positive ingredients. The problem though is the caffeine – and this in many ways is not good for you. While caffeine can boost your mood and help you to lose weight, it also has many unwanted consequences. One of the benefits of decaf coffee over regular coffee then is the fact that it doesn't include this caffeine and so won't have these same effects. So what does this lack of caffeine mean? What does caffeine normally do to you that's so bad? Here are some of the negative effects of caffeine and things that it can cause. Jitters: If you're sensitive to caffeine or drink too much then it can cause jitters causing your body to shake. Headaches: Many people get headaches from drinking tea and coffee in large amounts and conversely from stopping drinking coffee once they have developed an addiction. Nervousness: Coffee triggers the 'fight or flight' response meaning that adrenaline is secreted which is the same thing that happens when we are highly stressed. If you have a presentation to give and are nervous then drinking coffee just before might be the worst thing you could do. Likewise if you are of a nervous disposition already then it is not advisable, and if you are prone to panic attacks then this could even act as a trigger. Addiction: As mentioned if you stop drinking coffee after you have grown accustomed to it then you can suffer from headaches and this is becaus Continue reading >>

Effects Of Caffeinated And Decaffeinated Coffee On Body Weight And Glucose Tolerance
Habitual consumption of coffee may have substantial beneficial effects on glucose metabolism according to recent findings of epidemiological studies in the U.S., Europe, and Japan. However, data from longer-term human intervention studies with appropriate outcome measures are lacking. We will study the effects of caffeinated and decaffeinated coffee consumption on body fatness, insulin sensitivity and glucose tolerance that may underlie the observed associations with a lower risk of type 2 diabetes in a randomized controlled trial. We hypothesize that both caffeinated and decaffeinated coffee will improve insulin sensitivity and glucose tolerance. Before starting a larger, long-term intervention study, we will conduct a pilot study to test the feasibility of such a trial. The pilot study will be an 8-week parallel trial in 45 overweight individuals, who will be randomized to drinking 5 cups per day of 1) caffeinated coffee (n=15), 2) decaffeinated coffee (n=15), or 3) water (n=15). Body fatness (weight, waist circumference, bioelectrical impedance), insulin sensitivity (HOMA model), and glucose tolerance (oral glucose tolerance test) will be the primary outcomes. We will assess the adherence of participants to their assigned treatment by measuring serum caffeine concentrations, documentation of coffee use in diaries by the participants, and counting unused coffee packets. We will also obtain feedback from participants on how to improve compliance in a future trial. If successful, this study will form the basis for a definitive trial of coffee consumption, body fatness, and glucose tolerance. Given the extensive use of coffee and the rapidly increasing health burden of type 2 diabetes, such a trial would have important public health implications. Habitual consumption of 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 >>

Does Decaf Coffee Reduce The Risk Of Diabetes?
The release of a new study about coffee and diabetes has raised questions again about whether decaffeinated coffee is a healther choice for coffee lovers than regular coffee. A number of earlier studies on coffee and diabetes have shown that people who drink four or more cups of coffee a day reduce their risk of developing type 2 diabetes by 50 percent or more. The new study, published in the Dec 2011 issue of “Journal of Agricultural and Food Chemistry”, found that three compounds found in coffee may be the agents of that risk reduction. Kun Huang of Huazhong University of Science and Technology led a team of researchers who examined the effect of several compounds in coffee on the toxic build up of hIAPP (human islet amyloid polypeptide), a protein chain that has been implicated in the development of type 2 diabetes. They found that three of those substances — caffeine, caffeic acid and chlorogenic acid — appear to block the build up of hIAPP. More importantly, they found that the two acids have a significantly stronger effect against the toxic buildup than the caffeine. The team speculates that this inhibitory effect on the buildup of hIAPP may be the reason that coffee has a beneficial effect on preventing diabetes. If that’s the case, their research may provide a starting point for new, more effective treatments for type 2 diabetes and pre-diabetes. When asked about the effects of decaffeinated coffee, Huang states that he believes decaf coffee may be even more beneficial than regular coffee because the concentration of caffeic acid and chlorogenic acid is higher than it is in regular coffee, while the level of caffeine, which has uncomfortable side effects for many people, is greatly reduced. Huang’s team did not use actual coffee in their experiments, Continue reading >>
Effects Of Caffeinated And Decaffeinated Coffee On Biological Risk Factors For Type 2 Diabetes: A Randomized Controlled Trial
Abstract Coffee consumption has been associated with a lower risk of type 2 diabetes in prospective cohort studies, but the underlying mechanisms remain unclear. The aim of this study was to evaluate the effects of regular and decaffeinated coffee on biological risk factors for type 2 diabetes. Randomized parallel-arm intervention conducted in 45 healthy overweight volunteers who were nonsmokers and regular coffee consumers. Participants were assigned to consumption of 5 cups (177 mL each) per day of instant caffeinated coffee, decaffeinated coffee, or no coffee (i.e., water) for 8 weeks. Average age was 40 years and body mass index was 29.5 kg/m2. Compared with consuming no coffee, consumption of caffeinated coffee increased adiponectin (difference in change from baseline 1.4 μg/mL; 95% CI: 0.2, 2.7) and interleukin-6 (difference: 60%; 95% CI: 8, 138) concentrations and consumption of decaffeinated coffee decreased fetuin-A concentrations (difference: -20%; 95% CI: -35, -1). For measures of glucose tolerance, insulin sensitivity, and insulin secretion, no significant differences were found between treatment groups. Although no changes in glycemia and/or insulin sensitivity were observed after 8 weeks of coffee consumption, improvements in adipocyte and liver function as indicated by changes in adiponectin and fetuin-A concentrations may contribute to beneficial metabolic effects of long-term coffee consumption. clinicaltrials.gov NCT00305097.

Decaf Coffee Benefits The Brain
MORE Caffeine addicts may wonder: What's the point of decaf coffee? A new study suggests it may benefit the brain and protect against the mental decline that comes with aging and certain diseases. In the study of mice with Type 2 diabetes, those that consumed decaffeinated coffee for five months were able to better utilize sugar in their brains than those who did not consume decaffeinated coffee. Sugar metabolism — the breakdown of sugar by cells for energy — is often reduced in the brains of people with Type 2 diabetes, which can lead to cognitive problems. Similar impairments in sugar metabolism are seen in the brains of people with Alzheimer's disease. The study is the first to show the potential benefits of decaffeinated coffee for both preventing and treating the mental decline caused by Type 2 diabetes or other neurodegenerative disorders said study researcher Dr. Giulio Maria Pasinetti, a professor of neurology and psychiatry at Mount Sinai School of Medicine in New York City. Although regular coffee has been found to bring a number of health benefits, including a reduced risk of Alzheimer's disease, diabetes and some cancers, it also contains caffeine, which poses risks for the heart. Caffeine can increase blood cholesterol and blood pressure — both risk factors for heart disease. Decaffinated coffee contains compounds called pholyphenols, which are known to boost cognitive performance, Pasinetti said. The new study suggests some of the non-caffeine components of coffee, including pholyphenols, may also be able to ward off cognitive problems, Pasinetti said. However, because the study was conducted in mice, scientists don't know whether the same will be true for people. The researchers hope to study whether decaffeinated coffee can prevent age-related cogn Continue reading >>
