Women with diabetes who consumed these substances increased their life hopes.
A diagnosis of diabetes entails a long list of things that should not be done.But new research suggests that coffee and tea should probably not be limited, because each of them could help prevent it from dying prematurely.
At least if you are a woman with diabetes.Men with diabetes did not seem to obtain the benefits of consuming caffeine in the new study.
The investigation discovered that women with diabetes who took up to a cup of coffee a day (100 milligrams of caffeine) had 51 percent less likely to die than those who did not consume caffeine during the study of 11 years.
"Since more than 80 percent of the world's adult population consume caffeine, it is essentialSergio Neves, resident of Endocrinology at the Sao Joao hospital in Porto, Portugal.
"Our study showed a significant inverse association between caffeine consumption and mortality for any cause in women with diabetes," Neves said.
"These results suggest that advising women with diabetes who drink more caffeine could reduce their mortality. This would represent a simple, clinically beneficial and cheap option for women with diabetes," Neves said.
But he also indicated that this observational study cannot demonstrate a direct causal relationship;He only found an association between caffeine consumption and the risk of death.
"More studies are needed, and the ideal is that they were random clinical trials, to confirm the existence of this benefit," said Neves.
The study authors reviewed the information collected in an American study that included more than 3,000 people with diabetes, both type 1 and type 2. The data were collected between 1999 and 2010.
In addition to collecting information about general health, researchers asked participants about their caffeine consumption from coffee, tea and soft drinks.
In the course of the study, a little more than 600 people died.
The researchers observed that the more coffee a woman consumed with diabetes, the lower the risk of death.Women who took between 100 and 200 milligrams of caffeine a day in coffee had a lower 57 percent death than those who did not take caffeine.In women who took more than 200 milligrams per day in coffee (two cups), the risk of mortality was reduced by 66 percent.
The researchers adjusted the data to take into account factors such as race, age, level of education, income, smoking, weight, alcohol intake, blood pressure and diabetic renal disease.
The study found a different benefit from drinking caffeine in tea: an 80 percent lower risk of death for women who drank more caffeine from tea than those who did not drink anything.But the authors of the study indicated that there were only a small number of people who drank tea in the study.
Neves said that researchers are not sure of the reason why this benefit was not observed in men with diabetes.
"A possible explanation is in the biological differences between the sexes, depending on hormonal and non -hormonal factors, mainly at the cardiovascular system level," Neves said."Even so, we cannot exclude the fact that the sample of our study could have had a low power when detecting a smaller benefit from the consumption ofCaffeine for men. "
And what about the benefit of coffee for survival?How could this drink reduce the risk of death of a woman?
"The observed benefits could be directly related to caffeine or other components present in drinks containing caffeine," Neves suggested.
Previous studies have shown that coffee or tea consumption is associated with a better insulin sensitivity and better blood sugar control after eating in patients with diabetes, Neves said."In addition, minerals, phytochemicals and antioxidants present in drinks containing caffeine could also contribute to the benefits observed in women's mortality," he added.
Dr. Robert Cougi is an endocrinologist and diabetes expert at Southside Hospital in Northwell Health in Bay Shore, New York.
"Other studies have found that caffeine could be beneficial, and here there are more evidence that confirms it," said Court, who did not participate in the study.
And like the authors of the study, Courgi said that "more prospective studies should be done to demonstrate this supposed benefit of caffeine."
Neves presented the study findings on Thursday at the European Association for the Study of Diabetes (European Association for the Study of Diabetes), in Lisbon, Portugal.
