Food trend panda is permitted, eating last of bamboo cube? (5,4)

'food trend panda' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'permitted eating last of bamboo cube?' is the wordplay.
'permitted' becomes 'palet' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'eating' means one lot of letters goes inside another.
'last of' suggests the final letters.
'cube?' becomes 'die' (die is a kind of cube).
The last letter of 'bamboo' is 'o'.
'o'+'die'='odie'
'palet' enclosing 'odie' is 'PALEO DIET'.

'is' acts as a link.

Can you help me to learn more?
