Juicing Without Fiber? It May Be Disrupting Your Microbiome

Juicing is often considered a healthy way to incorporate more vitamin-rich fruits and vegetables into one’s diet, either as a daily practice or as a cleanse aimed at detoxification or weight loss.

However, new research shows that three days of drinking cold-pressed juice, which squeezes juice out of fruits and vegetables while stripping out their fiber, can cause a potentially damaging shift in bacteria living in the mouth and gut.
