i was doing really well for a week, couldnt remember the last time i had one full week without an attack. Anyway, on Saturday i ate a very ripe nectarine on an empty stomach and i have violent D almost immediately after eating the fruit and it carried on to the next day as well. I had no choice but to take immodium to stop the cramping.
any thoughts on this?
thanks

The problem here is an empty stomach. You ate IF on an empty stomach and your bowels disagreed with that  Never eat IF on an empty stomach and always in combination with SF.

Nectarines, apricots, pears, peaches, plums and some other fruits contain a sugar called sorbitol. This sugar is known to produce D even in non-IBS individuals.

I'm not so sure about that. I'm IBS-A and since the good weather began I've been eating those fruits all the time without getting D.

I am glad to hear you can eat these fresh fruits. I wish I could. Of course the amount of any sugar including sorbitol in a given fruit depends on a number of factors including growing conditions and the variety of fruit.
The most important factor is the sensitivity of each individual to the various simple sugars. For example, some IBS suffers cannot chew a stick of gum containing sorbitol without getting problems. A stick of gum contains a tiny amout of sorbitol compared to a nectarine. If you happen to be sensitive to small amounts of sorbitol and you eat a whole nectarine on an empty stomach you will feel the effects quickly and strongly.
Gracie perhaps you are lucky and you are not particularly sensitive to sorbitol.

Granted if someone has a sensitivity to it then yes I agree it can be a problem. I thought you were making a general statement about those fruits, and that's where I disagreed.
Next time, the poster could try to eat a nectarine with some SF to see if it makes any difference. If not, then she may have a sorbitol sensitivity.

thanks for the replies
is there a test for Sorbitol intolerance?

Yes - there is a sorbitol malabsorption. Also, sorbitol affects fructose absorption from the GI tract too. You can read about it in this article.
A recent study showed that less than 10% of IBS suffers and those with functional bowel complaints absorb the sugars sorbitol, fructose and lactose normally.

I agree with Gracie that your problem was most likely eating IF without an SF base. I can eat any fruit I want as long as I make sure I've got some SF in my system. Next time try eating your nectarine after having some SF or - even safer especially until you've been on the diet a little longer - try it as dessert after lunch.
