“I trouble to understand the structure of the last sentence. Each single word is understandable, but the whole construction I can’t get.”
Ok, let’s start with the original text.
While macadamia nuts and brazil nuts contain high amounts of unsaturated fats, they also contain higher amounts of saturated fats when compared to other nuts. Because of this, they are not allowed the “heart-healthy” distinction on their labeling.
In the second sentence, the word “this” refers to the statement that M and B nuts have higher amounts of saturated fat than other nuts.
Now for the rest of that sentence. First, some information I found. “Heart Healthy” is a term coined by the AHA. Food producers pay the AHA to have that term stamped on their food labels. So it is up to the AHA to either allow or deny a food producer the use of that term on the label.
The second part of that sentence implies that having “heart-healthy” stamped on the label of a food product would distinguish (“distinction” in the sentence) it from other foods as being good for you. Because the AHA considers the saturated fats in B and M nuts bad, the AHA will not allow the term to be placed on the label of B or M nuts.
“And another question is what describes of on their labeling quote?”
I am not sure but I think you are asking what “on their labeling” means. It means the printed information on the package of the nuts. They could also have written, “on the label”.
“If I wanted to implement this construction, how could I build my sentences by this way?”
Now lets get to your example, which is pure fiction and also a good opportunity to compare two different writing styles.
Fake name for organisation that regulates cell phone safety=CPS
Fake name of cell phone= NoXXX
Fake problem with the phone= health problems
Fake CPS stamp of approval= “Healty-Phone”
- The CPS has determined that use of the NoXXX causes health problems. For this reason, the CPS will not allow their “Healthy-Phone” distinction on the label of the NoXXX.
Now I will use the same style as the Nut example:
- While the NoXXX gets great reception, the phone also gets much hotter than other phones. Because of this, it is not allowed the “Healthy-Phone” distinction on its labeling.
Which one do you find easier to understand?
