Why doesn’t Roudybush add sugars to their diets?
The main reason we don’t add sugar to our diets, except for the diets of birds adapted to high levels of sugar, is to avoid the growth of yeast. Yeast, Candida albicans, is a common oral and gut infection in birds. Birds resist yeast infections by passing the yeast through the gut at a rate that keeps the level of yeast low. In the presence of sugar, however, yeast thrives and multiplies and can infect a bird eating a diet containing sugar. If yeast infections are common in your bird or if you are treating a yeast infection in your bird now, eliminate sugar from the bird’s diet if possible. This will reduce the rate of reproduction of the yeast leading to easier resistance to or elimination of infection in your bird.
