You want the sensational headlines to be true: "Pizza Packs Anti-Cancer Punch"; "Chocolate's Better Than Broccoli"; and "The Pub Is Better for You Than the Gym." But this month's issue of Popular Science debunks them by explaining their scientific sources in "Studies Suggest Headlines Are Bad for You."

The pizza that helps prevent cancer? It stems from a study, performed in Italy, in which the ingredients were olive oil, fresh tomatoes and mozzarella — not the extra sausage and double-stuffed cheese crust that Americans typically consume.

The notion that chocolate is better than greens comes from a short-term study at the Harvard School of Public Health that focused on high-cocoa-content dark chocolate — not the Snickers bars you find in the checkout line.

As for the study that appears to advocate logging in more pub time than gym time? It was from unpublished research showing that dogs injected with Guinness and Heineken experienced less clotting in their blood because of the high concentration of antioxidant flavonoids in the beer.
