If you have a problem with sweet fruits (like me!) you may have malabsorption of fructose especially. Sweet fruits especially are very high in fructose, and not everybody can handle this. I learned that in Central Europe for example 30-40% of the people have an intolerance to fructose! There is also a rare genetic disorder which we are not talking about here.
If you have malabsorption of fructose then you can eat acid or subacid fruits, yes, but in moderation. Those fruits also have fructose, and by eating a lot of them you may still get more than your system can handle. Tomatoes are also high in fructose. And if fructose is a problem for you then you may also have problems with wheat and onions for example which have a high percentage of fructans.
Glucose helps to absorb the fructose, so fruits with more glucose than fructose can be better tolerated. I found this list somewhere, see if it makes sense with your experience:
ratio glucose / fructose
apples 2,0 / 5,7
pears 1,7 / 6,7
pineapple 2,1 / 2,4
orange 2,3 / 2,6
kiwi 4,3 / 4,6
avocado 0,1 / 0,2
guava 2,1 / 3,4
mango 0,9 / 2,6
peach 1,0 / 1,2
watermelon 2,0 / 3,9
grapes 7,2 / 7,4
raspberries 1,8 / 2,0
strawberries 2,2 / 2,3
mandarin 1,7 / 1,3
muskmelon 1,6 / 1,3
litchi (lychee) 5 / 3,2
papaya (paw paw) 1,0 / 0,3
grapefruit 2,4 / 2,1
banana 3,6 / 3,4
granadilla (passion-fruit) 3,6 / 2,8
apricot 1,7 / 0,9
sweet cherries 6,9 / 6,1
dried dates 25 / 25
dried figs 26 / 24
dried plums 16 / 9
raisin (sultana) 31 / 31
prickly pear (opuntie) 4,9 / 0,1
sapodilla 6 / 6
sapote 3,4 / 1,4
mirabelle 5,1 / 4,3
