    Researchers have found that most people lose their appetite when served food dyed blue,
    because many blue plants and fruits in nature are poisonous.

    Extracted from my grammar book.

    I wonder if my grammar book has made an error regarding the unintentional omission of 'is' in front of dyed.

    I don't really think we can speak 'when served food dyed blue'.
    Instead, it should be 'when served food is dyed blue'

    Can anyone confirm it?

    Your book is correct. You don’t need “is” there.

    It's a reduction of a relative clause 'that has been dyed blue' so 'is' would be incorrect.
    'Served' is also a reduction, of 'when they are served'.

    Also, "served" isn't an adjective describing "food", it's a shortened version of a passive:
    Researchers have found that most people lose their appetite when served food dyed blue...
    Researchers have found that most people lose their appetite when they are served food dyed blue...
