Juicing is frequently viewed as a nutritious method to boost intake of vitamin-packed fruits and vegetables, whether as a daily habit or a cleanse for detox or weight loss. A study on juicing diets suggests it could be having the opposite effect and shows alterations can happen to the oral microbiome, with potential subsequent health impacts that may be harmful.
Recent research reveals that a three-day regimen of consuming cold-pressed juice, which extracts juice from fruits and vegetables while eliminating fiber, can cause changes in gut and oral bacteria associated with inflammation and cognitive impairment.
Juicing may harm gut health by eliminating vital fiber, resulting in a high sugar content that can promote harmful bacteria and upset the gut microbiome. Fiber plays a key role in supporting healthy gut bacteria that create anti-inflammatory substances such as butyrate.
The study involved three groups of healthy adults: one group drank only juice, another combined juice with whole foods, and the third followed a diet of exclusively whole plant-based foods. Researchers measured the bacterial communities from saliva and stool samples before, during, and after the diets, using gene-sequencing methods to examine bacterial shifts.
The group that drank only juice exhibited the greatest rise in bacteria linked to inflammation and increased gut permeability, whereas the whole plant-based food group displayed more beneficial microbial changes. The group combining juice with whole foods experienced some bacterial shifts, though less pronounced.
The results indicate that although juicing delivers nutrients, its lack of fiber and high sugar levels may harm microbial balance, causing long-term health issues. If you often begin your day with juice, try combining it with whole foods to minimize the risk of microbial disruptions.

Effects of Vegetable and Fruit Juicing on Gut and Oral Microbiome Composition
When working to control your weight, you probably prioritize your diet. Yet an often-ignored element that’s vital is your sleep quality. Sleep deprivation affects millions. It is estimated that more than one-third of adults consistently get less than seven hours of sleep per night. How well you sleep impacts your body’s processes, influencing your behavior, blood sugar, and eating habits.
Do you struggle to fall asleep or stay asleep? A poor night's sleep often leaves your brain feeling foggy the next day. Ongoing sleep difficulties could have serious long-term effects on brain health. New research indicates that sleep is essential for various brain functions, including cognitive health.
Although research on the gut-brain axis has surged, the role of intestinal inflammation, such as IBD, in speeding up cognitive decline among individuals with existing dementia remains poorly understood. A recent study investigates the gut-brain axis, focusing on ways to enhance and better manage this condition.
