Now, I know that a lot of people dismiss the importance of a natural diet for parrots choosing, instead, to feed pellets [which are nothing but 'dead' food] but it's important to remember that most [70%] of our immune system health comes from the flora in our guts as well as a good mood [95% of serotonin, nature's Prozac, is made there]. We are what we eat and parrots are what they eat so, please, feed food rich in phytonutrients!
