Unfortunately it appears that I cannot directly measure fructose amounts.
Nor can I differentiate between soluble and insoluble fibre.  Nevertheless
I can do basic macronutrient comparison which should give an inkling of the
truth.  I picked apricots, bananas, apples and oranges for no particular
reason except I like them, and because bananas and apricots are commonly
dried and apple and orange juices are the most popular.

Note: macronutrient content and fibre in grams.

One ounce of raw california (valencia) orange flesh: 13.89 calories, 0.28
protein, 0.09 fat, 3.37 carbohydrate, no fibre (?).

One ounce california orange juice: 12.47 calories, .23 protein, .09 fat,
2.86 carbohydrate, no fibre (?).

One ounce "all varieties" orange: 13.32 cals, .26 protein, .03 fat, 3.35
carbs, .68 fibre.

One ounce apricot nectar: 15.88 calories, .11 protein, .03 fat, 4.08 carb,
.17 fibre.

One ounce dehydrated apricot: 67.47 calories, 1.05 protein, 0.14 fat, 17.53
carb, 2.55 fibre.

One ounce raw apricot: 13.61 calories, .4 protein, .11 fat, 3.15
carbohydrate, .68 fibre.

One ounce banana flesh, raw: 26.08 calories, .28 protein, .14 fat, 6.63
carbohydrate, .68 fibre.

One ounce banana chips (dried banana): 147.14 calories, .65 protein, 9.53
fat, 16.56 carbohydrate, 2.18 fibre.

One ounce apple juice: 13.32 calories, .03 protein, .03 fat, 3.32
carbohydrate, .03 fibre.

One ounce apple flesh, with skin, raw: 16.73 calories, 0.06 protein, 0.11
fat, 4.34 carbohydrate, .77 fibre.


I'm still horsebacking this (I've only got so much time in one day) but it
looks to me that if I were particularly fond of dried fruits and fruit
juices (and I like both considerably more than I like fresh whole fruits),
I could pack in an awful lot of sugar from fruit in without trying hard,
and without getting in much fibre at all.

Let's quantify that: I could easily drink two quarts of either apple or
orange juice and five or six ounces of banana chips and dried apricots in a
day and still have room for regular meals.  I've done it many a time.  (I
drink more than two quarts of water a day.  I used to drink considerably
more than two quarts worth of soda pop and fruit juice every day.)  I would
be happy eating that way if I didn't know what it would do to my blood
sugar (it wouldn't be pretty, which is why I only drink water now except on
special occasion).

I'm not sure how this compares to the fructose amounts in the studies, I'll
have to look later.
