Water intake and protein:carbohydrate ratio confound Drosophilia calorie restriction studies, implications?

Ja et al. (1) recently published the results of a study exploring how hydration and nutrient manipulation effects the results of calorie restriction in Drosophilia. In non mammalian models, feeding rate is difficult to control, and often food is diluted with water without giving them a separate source of water.  Therefore, the specimens could be dehydrated and this could impact lifespan.  In mammal models of calorie restriction, water is given ab libitum. The first experiment used groups of Read more [...]
