All foods provided in the household are those fit for consumption (8)

'all foods' is the definition.
'eatables' can be an answer for 'foods' (eatable is a kind of food). I am not certain of the 'all' bit.

'the household are those fit for consumption' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'are' could be 'a' (short for 'are', historical unit of measurement) and 'a' is found in the answer.
'fit' could be 'able' (similar in meaning) and 'able' is found within the answer.
The remaining letters 'es' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'provided in' acts as a link.

Can you help me to learn more?
