If you've got type 2 diabetes and love drinking green tea or coffee, new research suggests you may be reducing your odds of a premature death.
But you need to really love these drinks. The study found that having four or more cups of green tea along with two cups of coffee daily was linked to a 63% lower risk of death during the average five-year follow-up.
On their own, a single cup of coffee or green tea daily might lower your risk of early death by 12% to 15%, respectively.
"Familiar beverages such as green tea and coffee may have health-promoting effects. We have shown that higher consumption of green tea and coffee was associated with reduced all-cause mortality, and their combined effect appeared to be additive in people with type 2 diabetes," said lead author Dr. Yuji Komorita, an assistant professor at Kyushu University's Graduate School of Medical Sciences in Fukuoka, Japan.
Komorita said it's unknown how either drink may aid health. Both contain nutrients that may reduce inflammation, among other healthful benefits. Since coffee and green tea together were linked to an even lower risk of early death, Komorita suggested that each may have different beneficial substances that act on different diseases.
But Komorita added an important caveat: This study was not designed to prove cause and effect. As an observational study, it can only find an association. Komorita also pointed out that researchers didn't have a lot of information about participants that could affect the findings, such as their education, income and family history.
The study included almost 5,000 Japanese adults, with an average age of 66, with type 2 diabetes. Almost 2,800 were men. Their health was followed for about 5 years.
Participants completed a lengthy food and drink questionnaire that asked how much green tea and coffee they had daily. They were also asked lifestyle questions, such as how much exercise they did, alcohol and smoking habits, and how much sleep they typically got.
Only about 600 participants didn't drink green tea. About 1,000 didn't drink coffee.
Of those who sipped green tea, more than 1,100 drank up to a cup a day, almost 1,400 had two to three and nearly 1,800 drank four or more cups each day, the findings showed. For coffee drinkers, 1,300 had up to a single cup daily, more than 960 had one cup and 1,660 had two or more a day.
During the follow-up period, just over 300 participants died.
Compared to people who didn't drink either beverage, participants who had green tea or coffee were less likely to die during the study, the researchers found. Those who drank both had the largest reductions in death risk.
And, the more you drank, the lower your odds of dying, the study found. Folks who had more than four cups of green tea daily had a 40% lower risk -- the same as those who had two or more cups of coffee. Those who had just one of these beverages daily had a 15% or lower odds of early death.
Dr. Minisha Sood, an endocrinologist at Lenox Hill Hospital in New York City, wasn't involved in the study, but is familiar with the findings.
"The positive effects of green tea are not specific to people with diabetes," she said. "It has been shown in multiple population studies that people in Japan who consume significant amounts of green tea experience a lower mortality rate from all causes and cardiovascular disease."
While the researchers found a similar link for people in Japan with type 2 diabetes, Sood said the findings may not apply to the U.S. population. The quality of the green tea in Japan is likely different, as is the population, she explained.
"It is also important to be cautious when interpreting the findings of this study because this group of patients was, on average, non-obese patients with controlled blood pressure," she said.
Registered dietician Pat Talio also suspected that the quality of the green tea may be different in Japan. She's the clinical nutrition outpatient program coordinator at Northern Westchester Hospital in Mount Kisco, N.Y.
Even more important, she noted, the amount the Japanese are drinking may be different and they're not necessarily adding cream and sugar.
"Green tea and coffee may provide a benefit for everyone because they're made from plants, and all plants -- like fruits and vegetables -- come along with beneficial antioxidants and phytochemicals that may reduce inflammation," she said.
Still, Talio added when it comes to hydration, "water is our best bet. If you do drink coffee or tea, think about how you're drinking it." If you're sweetening it and adding milk or cream, you may be reducing its health benefits, she said.
“ What does kidney disease have to do with this?”
Kidney failure and diabetes go together like a hand and a glove.
My relatives on my dad’s side had diabetes but not all who did developed kidney problems. Not a 100 percent chance by far; the risk factor is between 10% and 40%.
I take green tea extract and green coffee bean extract, both. Neither do I frequently drink hot beverages.
If you have type 2 you be getting your urine creatine levels checked often.
Mine also, but I only drink arabica bean coffee now and have no problems. It's not easy to find 100%. 8 O'Clock is one brand I buy.
Kidney disease is often the result of years of type II diabetes.
Other organs can be damaged too, because of the effect on blood vessels.
Think of what sugar does when spilled on your counter top. Imagine that in your blood. Honestly, it shows what a miracle your body is...putting up with that junk for 50 years and more.
There are two possible problems with this determination. First of all, according to the Mayo Clinic, if you already have diabetes the impact of caffeine on insulin action may be associated with higher or lower blood sugar levels. For some people with diabetes, about 200 milligrams of caffeine — or the equivalent of one to two 8-ounce (240-milliliter) cups of plain, brewed coffee — may cause this effect.
Caffeine affects every person differently. If you have diabetes or you’re struggling to control your blood sugar levels, limiting the amount of caffeine in your diet may provide a benefit.
According to WEBmd: A growing body of research suggests people with type 2 diabetes react to caffeine differently. It can raise blood sugar and insulin levels for those with the disease.
One study looked at people with type 2 diabetes who took a 250-milligram caffeine pill at breakfast and another at lunchtime. That’s about the same amount as drinking two cups of coffee with each meal. The result: Their blood sugar was 8% higher than on days when they didn’t have caffeine. Their reading also jumped by more after each meal. That’s because caffeine can affect how your body responds to insulin, the hormone that allows sugar to enter your cells and get changed into energy.
In another article from the Mayo it states that excessive thirst and increased urination are common diabetes signs and symptoms. When you have diabetes, excess glucose — a type of sugar — builds up in your blood. Your kidneys are forced to work overtime to filter and absorb the excess glucose. When your kidneys can’t keep up, the excess glucose is excreted into your urine, dragging along fluids from your tissues, which makes you dehydrated.
More people in history died from dehydration than the rest of the problems associated with diabetes. But type II is relatively new and not totally studied as it was not differentiated from type I until 1936.
In an article from Timesulin, for those with Type 2 diabetes, the effect during dehydration is as if their diabetes had suddenly kicked into overdrive, and glucose stops being broken down almost completely. This can make the body go into the high production of ketones that can lead to diabetic ketoacidosis and if not treated can be fatal.

“Not a 100 percent chance by far; the risk factor is between 10% and 40%.”
You are correct. Looking at it from the other side (kidney failure), about 40% of kidney failure patients are diabetic. Here is another interesting fact. 85% of those with diabetes are overweight.
So, a high percent of kidney failure patients are a result of being overweight.
See the article below for diabetes and kidney failure.

I spent three years on dialysis and the first time I marched myself into a dialysis clinic my first thought was — “look at all the overweight people.” I am not and was not overweight.
Our kidney problems (including transplants) could be greatly curtailed if people would only pay attention to nutrition and exercise (both of which help control weight [and quality and length of life]). The amount that the government spends on dialysis and kidney patients is incredible! Over $30B a year!
Dialysis is NOT fun and paying for it is even worse!
