How can ground turkey possibly contain more fat than ground beef, asks one Good Housekeeping reader. Hey, I'd like to know the answer to that question too. How about you?

GH Food Director Susan Westmoreland says in the January 2009 issue that both kinds of ground meat have varying amounts of fat. It all depends on what goes in the grinder.

OK, so here's the skinny: "Ground turkey breast" is the leanest, with one percent fat. "Lean ground turkey" mixes white and dark meat with some skin and totals about seven percent fat. This is comparable to "lean ground beef." Then there's "ground turkey," made from white, dark and skin, with 15 percent fat -- similar to "ground beef."

You've got to read labels, says Susan -- yes, that's what we're always saying -- in order to figure out exactly what you're buying. It can be tricky. Reading the word "lean" on a package of ground turkey can be misleading, because "lean" in this case is not the lowest-fat option.
