Cheerios launched a huge advertising campaign, a heart healthy campaign.

"Cheerios lowers your cholesterol!" shouts the advertisements. Sure enough, many friends believe that eating cheerios actually directly lowers your cholesterol levels, wherein the study that came up with this catchphrase had to do with replacing extremely high cholesterol breakfast foods with one bowl of cheerios per day proved to lower cholesterol over 8 months by a small amount.

That's a huge discrepency. That's like me eating five slices of cheesecake a day for half a year, then only eating one slice of cheesecake a day for half a year and claiming "Eating a slice of cheesecake a day lowers your weight!" It's simply not true.

Cheerios rests its head on a bed of "whole grain" marketing, yet you boil the grains down and all you've got is more carbs, which equals more converted fat to the belly which, yes Virginia, equals higher cholesterol.

I don't have a problem with breakfast cereals. I don't eat them because I'm on a paleo diet. But many people do, and are fine and healthy and have amazing metabolism. What I have a problem with is when unhealthy foods take a sliver of a factitious piece of information, and masquerade themselves as healthy products. Those are the real killers.
