The jury may be out on the exact effect of probiotics on the “good” gut bacteria, but protecting our flora is definitely important, given that we have ten times more microbes than cells in our body.

One way to get probiotics into your diet is through fermented foods. Sourdoughs, yogurts and things like kimchi and sauerkraut. To ensure that sauerkraut has been fermented and hasn’t been pasteurized, it’s best to make your own.
