Title: Increase in intranuclear nuclear factor {kappa}B and decrease in inhibitor {kappa}B in mononuclear cells after a mixed meal: evidence for a proinflammatory effect

You probably need to be in a University or pay for it to access it. The point of the paper was different than what the press release etc. stressed. The authors talk about a 900 k meal, they don't stress the fat or the carbs.

I also should point out that they were trying to mimick a typical American breakfast by the authors point, they actually consumed a drink with defined carb and fat that the authors considered a mixed nutrient breakfast. The paper is actually better than all the press comments on it - while you are right that n of 9 is low, they measure each subject before, at 1 hr, at 2 hr etc.. so they measured changes what happened within each subject over time.

"the subjects were asked to eat a mixed meal containing 910 kcal (egg-muffin and sausage-muffin sandwiches and 2 hash browns, which contained 81 g carbohydrate, 51 g fat, and 32 g protein) over 15 min. "
