Oiled Again!

“High Fat Diet May Make You Stupid and Lazy,” screamed the headline. “A new study on rats finds that 10 days of eating a high-fat diet caused short-term memory loss and made exercise difficult,” said the copy. There’s just one problem with the press release: the rats in the experiment were not fed fat, they were fed an oil. The fatty acid composition of the “high-fat” diet that caused memory loss and muscle weakness was 27% saturated, 48% monounsaturated and 25% polyunsaturated, which would be liquid at room temperature (http://www.fasebj.org/cgi/rapidpdf/fj.09-139691v1.pdf). The predominant fatty acid in the mix was monounsaturated, the kind of fatty acid in olive oil, peanut oil, canola oil and high-oleic safflower oil, the kind that is supposed to be so good for us. The problems encountered in the rats are typical of those encountered in diets high in industrially processed vegetable oils. So while the Diet Dictocrats are urging you to avoid meat, sausage and cheese, the foods you really need to avoid are cooking oils, commercial salad dressings, fried foods, chips, snack foods and bakery products like donuts and cookies. If anything will make you stupid and lazy, it is foods like these.

  1. Also, they only fed the diet to these rats for ten days. If the rats had been accustomed to higher-carb fare before then, they were adjusting to the new fat content. The same thing happens in people who start very-low-carb diets that put them into ketosis. We call it “induction flu.”

    Not that rat studies are completely applicable in humans. They may be similar to us as far as dietary needs but there are still some species differences.

  2. 1) Rats.
    2) 10 days
    3) Oils not fat

    If evidence exists that one is stupid and lazy, it is the wholesale acceptance of misleading facts as spun by media. Thank you, Ms. Fallon for another expose, and Ms. Hartke for blogging it!
