Coffee, Tea Consumption Linked to Lower Diabetes Risk

People who drink more coffee (regular or decaffeinated) or tea appear to have a lower risk of developing type 2 diabetes, according to a rigorous analysis of previous medical studies.

Each cup of regular coffee consumed in a day was associated with a 7% reduction in risk, according to researchers at the University of Sydney, Australia. Those who drank 3 to 4 cups per day had roughly a 25% lower risk than those who drank 0 to 2 cups per day.

People who drank more than 3 to 4 cups of decaffeinated coffee per day had about a 33% lower risk of developing diabetes than those who drank no decaf. And those who drank more than 3 to 4 cups of tea had a 20% lower risk than those who drank no tea.

“That the apparent protective effect of tea and coffee consumption appears to be independent of a number of potential confounding variables raises the possibility of direct biological effects,” the authors write in a paper published in the Dec. 14/28 issue of Annals of Internal Medicine.

Because decaf seems to offer protective benefits, caffeine is unlikely to be responsible for the reduced risk. Other compounds in coffee and tea—including magnesium and antioxidants known as lignans or chlorogenic acids—may be involved, the authors note.

Future studies will be required to determine whether therapeutic coffee and tea “doses” can help prevent type 2 diabetes—a disease that will affect 380 million people by 2025.

If such studies confirm these beverages’ interventional effects, the authors envision a time when “we advise our patients most at risk for [type 2] diabetes to increase their consumption of tea and coffee in addition to increasing their levels of physical activity and weight loss.”

We, of course, recommend organic coffee and tea to reduce your exposure to pesticides and toxic chemicals.

    There are so many health benefits to drinking coffee. This is one more reason to get up in morning and have a fresh cup of coffee!

    Findings from the Diabetes Control and Complications Trial (DCCT) and the United Kingdom Prospective Diabetes Study (UKPDS) have clearly shown that aggressive and intensive control of elevated levels of blood sugar in patients with type 1 and type 2 diabetes decreases the complications of nephropathy, neuropathy, retinopathy, and may reduce the occurrence and severity of large blood vessel diseases. Aggressive control with intensive therapy means achieving fasting glucose levels between 70-120 mg/dl; glucose levels of less than 160 mg/dl after meals; and a near normal hemoglobin A1C levels.

    I also think that one of the main reasons that is contributes to a better chance at avoiding diabetes is by being a better habit. It replaces drinking coffee or even in some cases smoking. So even though its not directly related, it helps by simply helping you avoid a more negative substance.

    In some diabetic patients the symptoms include loss of weight in addition to thirst, tiredness etc. When the glucose fails to enter the cells, the body starves for energy and the starved cells use fat and protein and this leads to weight loss.

    Drinking tea and coffee is a serious health hazard for the diabetic. Caffeine present in both tea & coffee is an addictive drug; stimulates Central Nervous System. Daily intake of tea and coffee increases blood sugar level and may lead to diabetes or aggravate symptoms.

    I would like to say, great blog. Im not sure if it has been addressed, however when using Opera I can never get the whole blog to load without refreshing several times. Maybe just my CPU. Enjoy!
