Sweet potatoes, potatoes, peas, etc convert to sugar and sugar feeds yeast. Brown rice is a complex carb and converts slower.
Grains aren’t always the problem, everyone at my work feeds a grain food and we all have a variety of dogs from little pups to mastiffs,pits, labs, and retrievers. We have more customers on a grain food that have left the grain free world due to the extreme high fat and carb protein sources.
This is out of one of Dr Beckers articles :
Yeast needs sugar as a source of energy. Carbohydrates break down into sugar. Both MDs and veterinarians advise patients with yeast to get the sugars out of their diets.
Dietary sugar isn’t just the white kind added to many pet treats and some pet foods. There are ‘secret,’ hidden forms of sugar that can also feed yeast overgrowth, for instance, honey. Although honey can be beneficial for pets in some cases, it does provide a food source for yeast. So if your dog is yeasty, you’ll need to carefully read his pet food and treat labels and avoid any product containing honey, high fructose corn syrup, and even white potatoes and sweet potatoes.
