With every fiber of my being I hate those cereal commercials claiming that "studies show" that people who eat whole grain live longer or weigh less than people who don't eat whole grain. It's statistic BS. Of course people health conscious enough to toss delicious fluffy carbs for scratchy brown carbs will live healthier, longer lives. This doesn't make cereal some miracle cure for death or obesity. It just shows a marketing tactic of showing causation by correlation.
It'd be similar to say that people who don't eat whole sticks of butter rolled in sugar everyday live longer than people who do. What kind of condition/mental state would one need to be in to eat a whole stick of butter rolled in sugar everyday? He/she is more likely on the edge of death more often than going for a morning jog.
