I had to find out what a quiche is to know what you had eaten. Although it sounds very tasty to me, the truth is that I would have skipped that base as well.
And not because I'm on a diet, but because I also avoid carbs and sugar.
I don't suffer from any health problems so far (knock on wood), but I avoid a lot of things so I don't suffer from anything.
I'm sorry you have something wrong with your health, but a good diet I think cures most illnesses.
As they say, food can be your medicine or your poison.
