I saw this on MSN.com and thought it was interesting.
Here's the one Im going to try out
Myth #1: "High protein intake is harmful to your kidneys."
The origin: Back in 1983, researchers first discovered that eating more protein increases your "glomerular filtration rate," or GFR. Think of GFR as the amount of blood your kidneys are filtering per minute. From this finding, many scientists made the leap that a higher GFR places your kidneys under greater stress.
What science really shows: Nearly 2 decades ago, Dutch researchers found that while a protein-rich meal did boost GFR, it didn't have an adverse effect on overall kidney function. In fact, there's zero published research showing that downing hefty amounts of protein—specifically, up to 1.27 grams per pound of body weight a day—damages healthy kidneys.
The bottom line: As a rule of thumb, shoot to eat your target body weight in grams of protein daily. For example, if you're a chubby 200 pounds and want to be a lean 180, then have 180 grams of protein a day. Likewise if you're a skinny 150 pounds but want to be a muscular 180.

I am only allowed 6oz of animal protein per day, so I try to make do with plant proteins most of the time.
