I don't agree with your first point. "Healthy" eating in this article (and in general) is quite unambigious in that it refers to the avoidance of foods that have been shown (to varying degrees of ambiguity) to increase your risk of developing health problems. This has nothing to do with an athlete's (short term) goals to build muscle or run a certain distance. Your second point should be included as a disclaimer by anyone trying to sell us the latest health craze.
