15. Water Kefir
Water kefir is made by adding kefir grains to sugar water, resulting in a fermented, fizzy drink that is loaded with probiotics. Unlike dairy-based kefir, water kefir is one of the leading natural vegan probiotic foods that can be appreciated as part of a healthy and balanced plant-based diet regimen. It’s also thinner than normal kefir and can be flavored using herbs and fruits.
