There is a problem with the research and their conclusions: "7.5% fat to a diet that was 55% fat (and 29% protein and 16% carbohydrate)"; that is too much PROTEIN for rats. I raised rats for a while in the 1990s, and giving rats too much protein causes visible skin problems; I would not at all be surprised to learn that it could cause the sort of minor mental deficits noted in the research.
