Category talk:Fermented foods

Are fermented beverages also foods?
Someone recently shifted some drinks from this category to a Fermented drinks category (whereupon I shifted them to Category:Fermented beverages since it was already well established). But are drinks like kefir, kombucha, kvass, and boza both fermented beverages and fermented foods? Which category do they belong in, or alternatively, do they belong in both?
