Dehydrated fruits portion =to fresh???

No, they aren't close. The hydration is water that doesn't have any calories but does take up room and has weight. 1/2 cup of dehydrated will have far more calories than 1/2 cup of fresh.

This article discusses fresh vs. dehydrated bananas.

ETA: I re-read your post. If you measure volume when it's fresh (or better yet weigh on a scale) and then dehydrate it yourself, you would use the fresh values because you've just lost the water and perhaps some water-soluble vitamins.

Oh no I wouldn't eat that much! LOL
That's not what I meant

Ok say (12 chunks) of fresh equals 1/2 cup
Then would those same (12 chunks ,just dehydrated) equal the same amount of nutrients. Just the same 12 chunks, not 1/2 cup fresh vs 1/2 cup dehydrated. Sorry if that was confusing. :-/

Yes, you'd use the fresh values in that case. 12 chunks of fresh would have the same nutrition (except perhaps for water-soluble vitamins) as those same 12 chunks when dried.

Are you buying them already dried, or drying them yourself?

If you're buying them already dried, I don't see how you can assume that the dried chunk started out the same size as a hypothetical fresh chunk. And if you're using MFP database entries for a fresh chunk, how do you even know that your mental image of a fresh chunk matches the chunk intended in the database entry? If you're buying them already dried, doesn't the package have nutrition information based on a serving size measured by weight?

Very good point.
Yes I buy fresh and make my own for my mix so it doesn't have stuff I don't want nor stuff I don't like in it. Most of my things are fresh and made from scratch (as much as I can). I've looked it up on the database and there are a lot that just had the calories and nothing else and some of those didn't seem right.

OK, then no problems. You can assume that the dried pineapple has the same calories, etc. as the fresh pineapple. Personally, I would weigh the total amount fresh, weigh the total amount dried, divide the before weight by the after weight, and use that number as a multiplier whenever I weighed and logged the dried pineapple. e.g., total weight fresh, 200 g; total weight dried, 50 g; 200/50 = 4; multiply dried weight by 4 and log it as fresh, using a database entry for fresh that mirrors the USDA database (https://ndb.nal.usda.gov/ndb/foods/show/2340?manu=&fgcd=Fruits and Fruit Juices&ds=Standard Reference)
