This is not a study, this is a press release based on a study. Always, always, always go to the actual study. The actual study is http://www.pnas.org/content/early/2014/12/25/1417508112.abstract http://www.pnas.org/content/early/2014/12/25/1417508112.abst... and it is paywalled. The main thing that jumps out about it, is that it is not just a dietary intervention; they also injected the mice with antibodies to Neu5Gc, supposedly to reproduce the levels found in the human immune system. Bad things happened only to those mice who were both fed Neu5Gc (at a concentration an order of magnitude higher than humans would encounter) and also gave them these antibodies. While this looks potentially promising, the human immunology would need to be studied, and what the effect size would be for a more typical diet is completely unknown.
