Tag: Juice fasting risks

According to a Northwestern Medicine study, a juice-only diet can cause changes in the gut and oral bacteria associated with inflammation and cognitive decline in as little as three days. This underscores the importance of understanding the full scope of what happens if you juice for 7 days, beyond just the promise of a 'detox'.

According to a 2025 Northwestern University study, a vegetable and fruit juice-only diet for just three days can alter gut bacteria, sometimes with inflammatory effects. A 3 day juice fast is a popular but intense practice that temporarily replaces solid foods with fruit and vegetable juices to reset dietary habits and boost nutrient intake.
