Coffee and 3 Other Beverages Good for Type 2 Diabetes
Scientists have once again reported that drinking coffee may reduce the risk of developing type 2 diabetes. The verification is good news for coffee lovers and is worth reviewing. At the same time, I also want to mention three other beverages that are good for type 2 diabetes.
Coffee for type 2 diabetes
Investigators at the Institute for Scientific Information on Coffee, who conducted the study, report that consuming at least three to four cups of coffee daily may reduce the risk of developing type 2 diabetes by 25 percent when compared with drinking less than two cups a day. The authors found that each additional cup of coffee consumed reduced a person’s risk of developing the disease by 7 to 8 percent.
Moderation is key, however, and more is not better. In fact, four cups of coffee daily is considered to be the safe limit, because beyond that point individuals risk insomnia, restlessness, irritability, stomach upset, rapid heartbeat, muscle tremors, and nervousness.
What ingredient in coffee is believed to provide protection against type 2 diabetes? Because both caffeinated and decaffeinated coffee was found to reduce the risk of type 2 diabetes in this study, caffeine does not seem to be responsible for the benefit.
However, a previous study (the Multiethnic Cohort) that evaluated more than 75,000 adults found that caffeinated, but not decaffeinated coffee was much better at protecting against development of type 2 diabetes among women of all ethnic groups (Caucasian, Japanese American, Native Hawaiian) than all ethnic groups in men.
Therefore, the reason for coffee’s protective effect against type 2 diabetes remains uncertain at this point. What about the three other beverages I mentioned? What benefits do they have concerning type 2 diabetes?
Beer and type 2 diabetes
Scientists at the University of Washington reported in a study published in early 2013 that they had identified the exact structure of the molecules in hops called humulones. What does this have to do with type 2 diabetes?
It seems that understanding humulones may help researchers develop new treatments for diabetes. In addition, another study found that derivatives of humulones called isohumulones significantly reduced both hemoglobin A1c and blood sugar levels in mice and individuals with type 2 diabetes.
Green tea and black tea
Both green tea and black tea have been found to be helpful in fighting type 2 diabetes. Among the benefits associated with green tea in animal and human studies of type 2 diabetes are protection of the retina against diabetic retinopathy, reduced risk of developing type 2 diabetes, and help with weight control and obesity.
Black tea also can provide important benefits when it comes to type 2 diabetes. A study published in BMJ Open in late 2012 reported that black tea reduces the risk of type 2 diabetes. An earlier study from scientists at the University of Dundee noted that black tea may help protect against type 2 diabetes because it contains theaflavins and thearubigins, phytochemicals that act like insulin.
Infused water. Put down the diet soda (full of unhealthy artificial sugars) and make your own infused water. Infused water is good for people with diabetes because it provides pure water for good hydration along with the goodness of fresh fruit and for virtually no to only a few calories, depending on the recipe.
What is your beverage of choice? Coffee, green or black tea, beer (in moderation of course), and infused water all provide some type of benefits for people who have type 2 diabetes.
