1/2 Chicken breast

Quote  |  Reply
Ok, so I've been told by some people that a whole chicken breast is ALL the meat off both sides of the chicken ribs.  Others have told me that the meat from only one side of the chicken is a whole breast.  SO...Which is it?

 A  serving of chicken is half a breast. A serving is also approximately 4 ounces. That leads me to believe that the whole breast is the meat from one side.
Original Post by mgrondin:

A serving is also approximately 4 ounces.

This is incorrect. A "serving" (as defined by the USDA) is 3oz. However, the "serving" system has been squashed since it creates confusion because people can't agree on how to define a serving. Its replacement is measuring ounces.

1 ounce is about the size of 2 board game dice. 3 ounces is about the size of a deck of cards, or if the meat is flat, the size of a checkbook. And, I don't know about you, but most of the chicken breasts I see are MUCH larger than that!

I define a chicken breast as a single side. If you were talking about a woman, one "breast" would not include lefty and righty, so why would chicken be evaluated this way?

"approximately 4 ounces".... 3 ounces.... I think I was in the ballpark.
Well it is 4 ounces of raw chicken in a serving.  Then once cooked it loses an ounce.  So you're both right! :)
ha, its nice when everyone can be right :)
The package of my chicken breasts says 1 serving = 4 oz. = 120 calories. 

I think a chicken breast is the meat  from one side of the chicken. It makes sense, right? Two breasts? 0_o

I think the back side of the chicken breast is called the tenderloin. So the breast is the white meat on the front side, and the tenderloin is darker and has more fat in it.. i THINK. Don't quote me on that. I'm pretty sure it's just the front side they are referring to.

If you cook a 4oz piece of chicken, you get aprox 2.5oz of chicken. At least from my kitchen experiments that tends to happen. USDA may suggest 3oz as a serving, but on a lot of packages it tells you the serving for 4ozs. *shrugs* Either way, I love my chicken.

I just checked my package of frozen chicken breasts, and it says on the package "whole chicken breasts"  and they are just the one half of the chest.  It also says "one serving (1/2 breast)=100cals.  So there you have it, one half of the one breast is a single serving.  Hope that helps.
Thanks everyone, I didn't think to check a package of chicken, duh!  I buy my chicken in bulk and then separate them into single piece packages to freeze.  I don't have scales, so I'm just ballparking it.  Kinda hard sometimes.  I eat a lot of chicken, mostly grilled on my George Foreman grill (love that thing!) or baked in the oven.  My husband keeps saying if we don't eat something else he's going to grow feathers, lol

Hi there,

I'm sorry to say that after some research I've come up with a different conclusion than you guys have. 

If you'll take a look at this site: -Tips--Techniques-642/cut-up-a-chicken.aspx

You'll see that a chicken has only 1 breast that is cut in half to make the two sides we think of as "two breasts."

I was pretty surprised, but it made sense once I looked at the cut up chicken.

Thanks for asking this question, I needed to know for a crockpot recipe.

Yes, a chichen has 1 breast but it's conveniently seperated by the chest bone making it easy to seperate into 2 pieces. Is a piece a serving, no. A serving (weight) is what you deem it to be based on your dietary food plan.

So the "left" and "right" parts of a chicken breast are considered together to be one chicken breast? I don't need to know serving size I'm just trying to figure the difference between one breast and one half.


I'm so glad you started this forum, because I have wondered the same thing. Judging from the replies, it seems the chicken industry considers one side of a chicken breast a whole breast, but technically a whole breast has two sides. You're right in that it has nothing to do with portion size.
