All Friday Fun Fact Marvelous Monday Messy Media News You Can Use Tuesday Talk
Media headline: What the media says: Reservatol is a compound found in red wine that has been shown to have positive impacts on health. Specifically, in rats it can increase physical performance, heart function, and muscle strength in similar ways as a workout. Journal title: What the article actually says: Ten-week old rats were randomly divided into four groups: (A) No exercise and standard diet (B) No exercise and diet supplemented with reservatol (C) Exercise and standard diet (D) Exercise and diet supplemented with reservatol. Exercise consisted of running on a treadmill for 60 minutes, 5 days a week, for 12 weeks. There were three main findings: (1) It was found that endurance increased in the rats who exercised compared to those who did not (i.e.,) groups C and D did better than groups A and B. (2) Among the two groups of rats who exercised, those who received reservatol had a 20% increase in performance and a noticeable increase in muscle strength (i.e., group D did better than group C). (3) When comparing the rats who exercised and ate a standard diet to those who did not exercise and ate reservatol, the rats who exercised outperformed sedentary rats (i.e., group C did better than group B). Why the media is messy: The article makes no mention of wine and other sources show that one glass of wine contains far less reservatol than the rats received in the study. The only human implications in the article suggest possible improved glucose performance and insulin sensitivity from a lifestyle of moderate exercised accompanied by reservatol. Bottom line: Red wine cannot take the place of regular exercise. Reservatol, a compound found in wine, can improve exercise outcomes, but it’s unclear how much a human would have to consume to see positive changes. AuthorsElizabeth C. Long & Jessica L.
