Thanks Kora that’s really interesting, but how can we refer to a UDIN moment especially that they quit eating this at a very young age they were only one year and a half and may be younger than that ? Also regarding feeling disgusted of the texture or taste how can it be especially towards all kinds of fruits ? I mean it seems logical if it’s one or two kinds of fruit right? Especially that they used to love it at younger age let’s say bananas as an example , they used to eat about 4 bananas a day they loved the taste a texture and used to ask for more even strawberries and other kinds but when they cut suddenly eating this they began with bananas ! The kind they loved it the most they hate it the most later on . Even if they see a juice or icecream or even a chocolate with a colored color from outside they recognize at a very early age that since the cover is colored there may be some fruits they’ll not even touch it or taste it , wer’re talking about the age of one year and a half here ! Recognizing that colored packaging could mean that there are some fruits here even if there aren’t , that’s why even colored candies or icecream they will not eat ! 
And both are different in age my daughter is 17 now and my son is only 4 years old with same attitudes of his sister ! Could it be that he had some VAGOKS ? May be seeing his sister reactions at a very you g age toward fruits ? 

Regarding the other possibility (enzyme) , it seems reasonable but also how can it be to all kinds of fruits and veggies? And I forgot to tell you that with time they also began to cut any kind of protein but I was trying to let them not do that by exposing them to proteins more often , it worked with my daughter but her brother is now hardly eats them , and I realized when I let him sometimes eat meat or chicken he will for the coming days have flue like symptoms and he’ll lose his voice it affects his vocal cords but it’s not always like that !
