Why is the amino acid/protein completeness of ground beef almost half that of steak?

I mean, isn't ground beef just ground up steak basically?

At 79, it's only 4 points higher than rice for being a complete protein, http://nutritiondata.self.com/facts/cereal-grains-and-pasta/5707/2 .

@Mscott, I agree. It's also a word of caution to some though, that if they eat most their protein from ground beef, they need to balance that with another protein source rich in tryptophan , possibly turkey or egg whites or something.

But yes the cartilage would add to the glutamine and junk.

Lol Mary, you shouldn't be flirting on ForeverYoung over here, you might explode his ego. @forever, I think it may have something to do with the tryptophan and the fact that ground beef has some cartilage and other incomplete proteins added in the mix which results in it being more incomplete. I'll have to research some more on it though to figure out the complete picture.

By that measure though ground beef is at 79 which is like an incomplete protein, but steak tops the list at like 154 or something depending on the cut.

They have , on the right a protein quality/amino acid score box where they give it a number based on the completeness of the protein.

I don't know man. That's weird. Mary is probably right though. Just different body parts. Like I'm sure chicken breasts have a different amino acid score than chicken thighs (which would account for their different colors as well).

@forever, I thought that too, but if you look closely at the data you'll see That the Ground is 47% calories by fat while that particular steak/roast is 67% calories by fat, so the nverse is actually true! And this one is almost identical calories from fat as the ground beef but the amino acid score is literally Almost double http://nutritiondata.self.com/facts/beef-products/3820/2 .

...the one for the ground beef is for 22 grams of protein, and the amino acid scores on the steak is for 64 grams of protein. So, the steak will show a higher amino acid score. Did you adjust them for the same amount of total protein and then look at the amino scores? they're prolly the same that way.

yes.. diffrent areas - sum more muscley, sum more sinewy and cartilaggy..sum more fatty... so it depends. I saw a steak at this fancy grocery shop it was litterally ..55 buxx! for one steak! it had fine fine marbling all through it. prolly similar to Kobe beef.Actually thats wut it prolly was. Click on that pic of the cow on bb.com it shows all the dif parts.

I don't get it though, why do steaks have a higher quality/more complete protein than the ground beef? Is it because of their location on the cow?

The ground beef is 10% fat and the steak is 0% fat. so, more protein/gram.

Usually they save the cheaper tuffer cuts for ground beef.. cuz its lil and more easy to digset and cook up cuz its in weeee lil itty bitty pieces.

Okay, so the reason Ground Beef has a lower Amino Acid Completeness score, and why it is a poorer source of protein than pure steak seems to be because regular ground beef tends to include more than just the muscle meat of the cow. It might include some

Because the ground beef can include more than just the pure muscle, it might be combined with more incomplete proteins, like gelatin (from the connective tissue) which is an incomplete protein and contains no tryptophan. This would help explain why ground beef is less of a complete protein than steak since it is combined with more incomplete proteins which are low or absent in tryptophan.

This is my best guess answer, I'm pretty sure it's right, but if you have more information on the subject please do share :).
