Everyone is missing the point here I think.
The mucousless diet is based on non-starchy vegetables and fruit.
Bella Lucia may still be eating starchy vegetables (mucous-forming for some) which should be avoided.
The most common foods to cause mucous (from personal & others experience) are cheese, dairy generally, and wheat products, in whatever quantity and however miniscule this may be.
Any mucous forming foods will need to be eliminated from the diet "completely" for any benefit to be had, regarding Hay Fever and skin diseases generally.
This is a trial, which I think will work for Bella Lucia in the long-term.
