TUESDAY, Feb. 18, 2025 (HealthDay News) – Juice cleanses are a popular way to kickstart a health journey, but these diets may do more harm than good in as little as three days. A study published recently in the journal Nutrients found that consuming vegetable and fruit juice-only diets for three days triggered detrimental gut and oral bacteria changes linked to inflammation, memory and thinking problems. Exactly how juice-only cleanses trigger such changes is not fully understood, but researchers suggest it may owe to the lack of fiber in juice. “Most people think of juicing as a healthy cleanse, but this study offers a reality check,” said study author Dr. Melinda Ring, director of the Osher Center for Integrative Health at Northwestern University Feinberg School of Medicine in Chicago. “Consuming large amounts of juice with little fiber may lead to microbiome imbalances that could have negative consequences, such as inflammation and reduced gut health,” she said in a news release. When fruits or veggies are juiced, much of the fiber is stripped away. Fiber feeds good bacteria that produce anti-inflammatory compounds. Without fiber, sugar-loving or bad bacteria can multiply, disrupting the balance of good and bad bacteria — known as the microbiome — in the gut and mouth. To see how juicing affects the gut and oral microbiomes, researchers studied three groups of healthy adults. One group… read on > read on >
