Conflicting steak stats

WraithTDK

I see a lot of conflicting information about the protein:fat ration lean cuts of steak. In particular, eye of round. Seems every article I read on leanest cuts of steak (example 1 and 2) lists it as have a 5-7:1 ratio of protein to fat.

On the other hand, any time I look at "nutrition stats" pages, they list it as having a 2:1 ratio. I'm almost wondering if the various stats sites just looked up stats for "steak" and applied them to anything that's classified as "steak."

Thoughts?

Digging further, I've emailed the writers of those articles. More examples of conflicting information on eye of round:


utritiondata.self.com/facts/beef-products/3553/2 lists 3oz as having 25g of protein, 3g fat. 8:1
calorieking.com/foods/calories-in-beef-beef-eye-round-roast-lean-only-roasted_f-ZmlkPTYxMjAz.html says 3oz has 24g protein, 3oz fat. 8:1
caloriecount.com/calories-beef-round-eye-i13184 24.6g protein, 4.2g fat. about 6:1
fitbit.com/foods/Beef+Eye+Of+Round+Raw+Slf/25973 6.1g protein per ounce, 2.3fat 2.7:1
sparkpeople.com/calories-in.asp?food=eye+of+round+steak 5.5g protein per ounce, 2g fat. 2.75:1


I think that I've come to the conclusion that different sites are counting different preperation methods, such as whether or not all the fat is trimmed completely off of it, and others are more community-based and are probably either mirroring each other, or entering generic "this is what steak has" without expecting there to be as much differences in cut. On average, I'm estimating 7:1 with about 8.16 grams of protein and 1.16 grams of fat per gram. I'm interested to see if the writers responde.

Can't help you with this, as I'm from the UK I actually had to look up what an 'eye of round' was. It's a beef silverside cut here.

Use the numbers from the USDA. That is as close as you are going to get because those sites are relying on US. government data. Some pork cuts are low-ish in fat too.
