I am Jack Sprat

I was really "Jaqck Sprat" until I became 20-30 y/o.
I could not eat fat part of any meat except thinly sliced bacon of whales.
All because I felt sick if I ate.
I could not eat cream part of any sweet cakes. 
So I asked my parents not to buy a sweet cake with any cream on it for my birthday.
All because I felt sick if I ate.
I have never met such a person in my life except this "Jack Sprat".

"Jack Sprat could eat no fat
His wife could eat no lean
And so between the two of them
They licked the platter clean."

"Jack ate all the lean,
Joan ate all the fat.
The bone they picked it clean,
Then gave it to the cat."


Could this be any syndrome or even disease ?
