Using my limited ability with search engines and atrocious typing skills I have come across the following in the X, Y, Z range of fruits.
Yangmei
Yantok
Yardlong bean
Yellow buckeye - ineddible
Yellow granadilla
Yellow mombin
Yellow oleander - poisinous
Yellow plum
Yew cones with seeds unremoved - no eat with seed or else end up killdead
Youngberry
Yuzu
Zig-zag vine fruit
Zucchini
Zwetschge
I included legumes and the like since they are technically part of the plants fruiting bodies that are consumed
I would like to add to the list in no particular order
Sweet Pea
Currant - Black, Red and white though red is my fave and my bushes are ready for harvest early this year.

Mulberry because as kids we feasted on these every summer and our tree was HUGE with MASSIVE fruits, no little thanks to being within a few yards of the compost heap in the corner of the garden.
