I agree with most of the commenters of yesterday's post... Good for him.
The reason I brought this topic up was the numerous articles and blogs that I had read that all included comments from various doctors and nutritionists that commented that Wheaties is a far more healthful product than Frosted Flakes, like this and this and this and this and this and this.
I think the endorsement is fine. Phelps should get all he can while staying legit (what I mean is Frosted Flakes is good, while an on-line porn site is bad). Kellogg's is a business to make a profit, and apparently Frosted Flakes is a good brand for them. Kudos to Phelps for getting a deal, kudos to Kelloggs for reeling in a big fish, and kudos to the responsible parents out there that monitor their childrens junk food intake.
Some junk food is good, and as long as the parents are teaching dietary balance and keep reasonable serving portions, I see no problem with this endorsement at all. And about the parents that aren't montioring their kid's intake of sugarey cereal... well, that isn't Phelps or Kellogg's problem.
