Many studies have previously shown that tea and coffee can reduce the risk of death. A new study shows that people who have type 2 diabetes can also get these benefits.
Drinking green tea and coffee has been linked to a reduced risk of death in people who have type 2 diabetes. New research suggests this. published at BMJ Open Diabetes Research & Care.
The study was conducted in Japan. It involved almost 5,000 diabetics with an average age of 66 years, they were followed up for 5 years. Scientists have focused on the potential effect of drinking tea and coffee, individually and in combination, on mortality.
In people with type 2 diabetes who drank one cup of green tea a day, the risk of death was reduced by 15%, two to three cups by 27%, and four cups by 40%. Similar data were obtained for coffee: one cup a day was associated with a 19% reduction in the risk of death, two cups – 41%.
When alternating green tea and coffee, the effect was enhanced:
- two to three cups of green tea and two cups of coffee a day were associated with a 51% risk reduction;
- four cups of green tea and one cup of coffee – 58%;
- four cups of green tea and two cups of coffee – 63% higher.
This was an observational study. Scientists emphasize that this type of study cannot prove that it was the consumption of tea and coffee that extended the lives of its participants.
The authors of the scientific work point out that tea and coffee are high in antioxidants and anti-inflammatory components. This could potentially explain the fact that their use is associated with a reduced risk of death.
