[QUOTE="BravoKilo, post: 2455651, member: 548600"] The problem is more with the Headlines that the study itself, IMHO. The study was small (49 people), but at least was an RCT. Not much can be read into the findings given the size of the experiment; all you can say is that in their they found some effect from eating raisins. The study itself showed (not in the Media or Abstract!) that snacks made things worse for the Snack group ... so Raisins are better than Snacks, but no snacks....? For the geeks: Looking quickly at the study [URL]http://www.californiaraisins.de/fileadmin/user_upload/2015_Bays_H.__Raisin_DM_Sports_Medicine_Final.pdf[/URL] yes, it was sponsored by the California Raisin company! - the randomisation itself left the two groups somewhat different (e.g much higher pre test lab results in raisin group (eg 30% higher post prandial glucose ) higher BMI, waist circumference, more race diversity, etc). This could easily dominate any effect due to raisins alone. - the snacks (which look like they were calorie matched and approx carb matched) all led to increases in the measurements for the snack group), some of which would be statistically significant - "statistically significant" used in the conclusions can easily mislead, especially in a small study like this, and of course doesn't directly relate to the truth of whether Raisins caused a real effect.
