A Measurable Shift in the Gut Microbiome
A 2017 study published in Scientific Reports followed 20 healthy adults drinking six cold-pressed vegetable and fruit juices per day for three days. Researchers observed a rapid shift in gut bacteria toward Bacteroidetes — the family associated with leaner metabolic profiles — along with an average 1.7 kg weight loss and a significant drop in plasma lipid peroxides (a marker of oxidative stress).
