whats the difference? and which steaks the best
 

What is the difference between, Prime, Select, Choice, and all grade steaks?


And which of all these is the best/ leanest steak, to build muscle?

Beef, bottom round
- separable lean and fat, trimmed to 1/2" fat, prime,
- separable lean and fat, trimmed to 1/8" fat, all grades, raw
- separable lean and fat, trimmed to 1/8" fat, choice, raw
- separable lean and fat, trimmed to 1/8" fat, select, raw
- separable lean only, trimmed to 1/2" fat, prime, raw
- separable lean only, trimmed to 1/8" fat, all grades, raw
- separable lean only, trimmed to 1/8" fat, choice, raw
- separable lean only, trimmed to 1/8" fat, select, raw
- separable lean and fat, trimmed to 0" fat, all grades, raw
-separable lean and fat, trimmed to 0" fat, choice, raw
- separable lean and fat, trimmed to 0" fat, select, raw
- separable lean only, trimmed to 0" fat, all grades, steak, raw
-separable lean only, trimmed to 0" fat, choice, raw
- separable lean only, trimmed to 0" fat, select, raw


and same would go for

Beef Top Round
and
Beef Sirloin tip?

I think sirloin tips are all the fatty trimmings of the top sirloin

i guess there are all about the same for 8 oz raw- cube steak, bottom round steak, top round steak, sirloin tip steak-

320 cals
12 gram of fat and 50 grams of protein


for these cuts
