Serving Sizes

I got this today from my Bally's Fitness email of the day. I was so surpised to learn that two tablespoons of peanut butter (what I usually put on my pb and jelly sandwiches is equvalent in protein to an ounce of meat!

Here is what I read this morning:

Did you know that two tablespoons of peanut butter is the same size as a golf ball, which counts as one serving and is equivalent to an ounce of meat? Did you know that one serving (1 1/2 ounces) of cheese is about the size of three dominoes, and that one serving of leafy-green veggies is one cup, and about the size of a baseball?
