A study that has recently made headlines, has found some evidence that quitting smoking might increase the short-term diabetes risk. This increase in risk is believed to be due to weight gain often associated with quitting smoking. When accounting for weight gain, the increased risk was almost nonexistent.
Although this study has been misused as a pro-smoking argument, smoking is still considered a number one killer, alongside obesity, and although for unknown reasons can increase the risk of getting diabetes. The researchers point out that quitting smoking is still the best thing to do, but that this study highlights the importance of weight stability after quitting smoking.

According to a systematic review and meta-analysis of 18 studies on coffee and tea consumption (decaffeinated included) an inverse association between the consumption of coffee and tea and the risk of type 2 diabetes mellitus has been found. Each additional cup lowered the incidence of diabetes with an additional 7%. These results included decaffeinated coffee as well, removing the possibility that the caffeine might contribute to the positive effect. While the researchers are thrilled with the findings they warn that more studies need to be done before people are advised to consume these beverages in order to ‘avoid’ diabetes. Today diet and exercise is the still the main advice to lower the risk of type 2 diabetes mellitus.
