Boston, MA—A Harvard University study provides new insight into the long-term link between coffee consumption and risk of developing type-2 diabetes. The study, published in Diabetologia, is based off of previous observational data from three large studies: The Nurse’s Health Study, profiling female nurses from the ages of 30–55, the Nurse’s Health Study II, consisting of female nurses between the ages of 25–42, and the Male Professionals Follow-up Study, consisting of men ages 40-7–5. In all three studies, detailed information on diet, lifestyle, medical conditions, and chronic diseases were taken every two to four years for over 20 years. For the purposes of this study, the authors tracked 7,629 type-2 diabetes cases and the amount of tea and coffee they consumed daily, both caffeinated and decaffeinated. Results of the study showed that participants who increased their consumption by more than one cup a day over a four-year period experienced a 11% lower risk of type-2 diabetes in the following four years, while those that decreased their consumption by one cup or more experienced a 17% increase in risk of type-2 diabetes. In addition “high-stable consumers,” people who consistently had more than three cups of coffee a day, had a 37% overall lower risk than subjects that consumed one or less. While decaffeinated coffee at the baseline was associated with lower risk of diabetes, changes in consumption presented no shift, and tea consumption presented no change in risk at all. While this certainly presents a correlation between increasing coffee intake and decreasing type-2 diabetes risk, the heads of the research, Frank Hu, M.D., Ph.D., and Shilpa Bhupathiraju, Ph.D., caution that those with conditions associated with high diabetes risk (e.g., high cholesterol, cancer, cardiovascular disease) may have decreased their coffee intake following diagnosis, potentially creating some reverse causation. However, the researchers found that even after excluding these conditions from the data, the trend was still clear. Published in WholeFoods Magazine, June 2014

Kava može smanjiti rizik od dijabetesa? Novo istraživanje provedeno na Harvardu sugerira kako je češća konzumacija kave povezana s manjim rizikom za razvoj dijabetesa tipa 2 Podaci prikupljeni od 123000 ispitanika tijekom 4 godine pokazuju kako je povećanje konzumacije kave za više od jedne šalicu dnevno bilo moguće povezati s 11%-tnim smanjenjem izgleda za obolijevanje od dijabetesa tipa 2 u sljedeće 4 godine. Kod osoba koje su u promatranom razdoblju smanjili konzumaciju kave je uočena za 17% veća učestalost dijabetesa tipa 2 u sljedeće 4 godine, piše stručni časopis Diabetologia. Istraživači nisu sigurni koji sastojci kave mogu utjecati na rizik za dijabetes tipa 2, no vjeruju kako je riječ o djelovanju niza antioksidansa i drugih hranjivih tvari iz kave. Raniji eksperimenti su ukazali na postojanje uzročno-posljedične veze između većeg unosa kave i smanjenja rezistencije na inzulin. Rezistencija na hormon inzulin je jedan od znakova upozorenja za dijabetes. U novoj studiji je utvrđeno i kako kava bez kofeina ne utječe na rizik za razvoj dijabetesa tipa 2
