Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.

Question: original question: How many dietary restrictions are incompatible with [Lamb and mutton]? 
answer: 2
answer type: Dietary restriction.
auxiliary information: Lamb, hogget, and mutton are terms for the meat of domestic sheep at different ages. A sheep in its first year is called a lamb; and its meat is also called lamb. The meat of a juvenile sheep older than one year is hogget; outside North America this is also a term for the living animal. The meat of an adult sheep is mutton, a term only used for the meat, not the living animals. The term mutton usually refers to Goat meat in the Indian subcontinent or South Asia. Lamb is the most expensive of the three types, and in recent decades sheep-meat is increasingly only retailed as "lamb", sometimes stretching the accepted distinctions given above. The stronger tasting mutton is now hard to find in many areas, despite the efforts of the Mutton Renaissance Campaign in the UK. In Australia, the term prime lamb is often used to refer to lambs raised for meat. Other languages, for example French and Italian, make similar, or even more detailed, distinctions between sheep meat by age and sometimes by gender, though they generally lack the particular habit of English in having different terms for the living animal and its meat.

Answer:
What are the main nutritional benefits of [Lamb and mutton]?
