In issue 21 of the CrossFit Journal, 1 oz. of protein powder is listed as 1 protein block.

A few days ago I purchased some whey protein powder. On the nutrition facts label, it lists a serving size of 28g (roughly 1 oz.) as having 20g of protein.

Since 1 block of protein is 7g, does this mean that one serving size of this protein powder should actually counts as ~3 protein blocks?

1 oz. @ 20g protein / 7 = 2.85 blocks

Am I doing this math correctly, or am I way off?

Thanks for any guidance!

I am guessing that they mean 1 ounce (by volume) of protein powder weighs 28 grams. Issue #21 is definitely using weight measurements in that protein table, not volume.

Aaron, you're doing your math right. Different powders will have different levels of protein. If there's a difference between what I read in a Zone block chart, and what I read on the nutrition label of the food I'm actually eating, I go with the label.

You are right Aaron, you'll find for most things, if you find the nutrition facts, it will be off.

For oats, for example, that 1/3 cup cooked has fiber in it, so it really is less. Just like your average kiwi has 11g of carbs, but if you eat the skin, that could be 6g of fiber, so you are only using 5g of it as a carb.

I tend to eyeball a scoop of protein powder as 1/3 of a scoop = 1 block of protein.
