In recent times a study has been circulating that I have not reported on this blog, as happens a few times: in the sense that, before giving the news, I wait for it to be discussed again, even after a few months, or that the study is mentioned and taken into consideration by others, that there have been insights of some kind or, as has alas happened, sensational denials of its veracity.
In this case, I am happy to have waited to give the news of a study that sanctioned the usefulness (better than water, it was said) of dietary drinks such as Coca cola Zero in slimming diets , in spite of studies that have correlated a risk of obesity and diabetes also with the consumption of sweetened drinks. Previous studies had indeed finally founda link between diet soda consumption and weight gain , and although the aforementioned sodas are calorie-free, they would still cause insulin resistance .

Now, the new study, led by Dr. Peter Rogers, professor of biological psychology at Bristol University, and published in the International Journal of Obesity, contradicted the work of independent researchers in recent years with a major counterattack: not just diet drinks, it was said, they would not favor the accumulation of weight, but on the contrary from the analysis of the data of the previous studies they would be even more effective than water.
Instead, it turned out that the study would be funded by a research institute that has Coca Cola and Pepsi-co among its board members.. And the people who did the study would be paid by the institute. Let’s say there would have been a double conflict of interest. The justifications of the researchers, who would not have mentioned this funding, do not convince.
