Cautious Studies Tend to Disprove Dietary Longevity Claims
A research group is presently working through a grand tour of replicating longevity claims in mice, using careful and cautious study designs that eliminate calorie restriction effects as much as is possible. This sort of approach shows that many past claims of dietary additions that modestly extend life in mice were probably the result of inadvertent calorie restriction - which is why you have to look carefully at every study to make sure that researchers controlled for this issue.
