In general worms can cope with nearly all garden- and kitchen waste you might offer them. Some products the compost worms can eat in large quantities and even live in them while others should only be fed in moderation.
Especially acidic foods should be fed with care. If the acidity of your worm bins bedding becomes very high it might force your worms to migrate out of the bin to avoid death.
