Chicken is my favourite food.
However, it gets a little tricky and is open to interpretation when we have more than one subject that is non-count.
The issue to consider is whether the non-count items are to be considered as a unit, where "and" forms part of the compound-noun expression, or if "and" is being used as a conjunction, separating two completely different items, as if in a list.

Compound-noun expression - unit.

"And" is being used as a conjunction.
