Wording a sentence for "A, B, C, D, or E" with inclusive and exclusive "or"

In my papers, I often need to formulate disjunctions textually (for example, when providing conditions for the fulfillment of a statement).

Let’s see two examples:

1. When you eat (a) apple, (b) pear, (c) orange, (d) banana, or (e) pinapple,
   you provide important vitamins for your body.

   (inclusive disjunction)

2. I don’t know whether Joe has (a) one, (b) two, (c) three, (d) four, or (e) five children.

   (exclusive disjunction)

Of course, the meaning of or is clear in these sentences, but one could give examples, where it is not evident whether inclusive or exclusive or is used.

Is there any way to emphasize the real meaning of or in (1) and (2)?

I usually fix in my papers that A, B, C, …, or Z always indicates an inclusive disjunction, but what can I do when A, B, C, …, or Z should mean an exclusive disjunction? How should I express such an exclusive choice?
