How much table foods should be given to a bird per day?

I have a healthy cockatiel. He is on a pelleted diet, and occasionally gets treats, fruits, and veggies. My question is, how much table foods should he have a day? My vet said one small amount of table food a day. Such as one day he gets broccoli, the next a carrot etc. Is this a good recommendation? Thanks!How much table foods should be given to a bird per day?
Personally I think you can give more than that . Raw is better than cooked. No salt is best. Many people give their birds mixed veggies and fruit everyday. You can also give your bird a pasta noodle . most birds like it cooked,a small piece of whole or12 grain bread,sweet potato and dandelion greens.How much table foods should be given to a bird per day?
Keep a sprig or bloom of fresh broccoli in his cage daily. The carrot is good too, raw, alternating with different mixed vegetables - fresh or thawed-from-frozen. Remove dried or stale food, just as regularly as you add it. I believe that various melons would make good treats, and are good for digestion. I can not verify or refute the offering of carbs or bread, but might give a little bran muffin - northing too sugary. Fruits will have natural sugar, and carbs convert to sugar already.
