The gut microbiome, composed of various microorganisms, is essential for maintaining health, and its dysbiosis is linked to the progression of inflammatory bowel disease (IBD).

IBD is a chronic inflammatory gut disorder that includes ulcerative colitis (UC) and Crohn's disease (CD), with symptoms such as diarrhea, rectal bleeding, and abdominal pain affecting millions globally.

While the precise cause of IBD remains unclear, environmental factors and microbiome dysbiosis are believed to exacerbate the condition in susceptible individuals.

Intensity-modulated radiotherapy (IMRT) aims to minimize side effects in cancer treatment but can still lead to significant salivary dysfunction, impacting survivors' quality of life.

The FDA's recent approval of Kisunla, a drug targeting amyloid-beta plaque accumulation, marks a significant advancement in Alzheimer's treatment strategies.

Despite advancements in understanding Alzheimer's disease (AD) mechanisms, including neuroinflammation and the role of gut microbiota, effective disease-modifying treatments remain elusive.

Recent research highlights the role of gut and oral microbiota in neuroinflammation related to AD through the microbiota-gut-brain axis, suggesting dietary interventions or probiotics could be promising strategies.

Factors such as gender, smoking, and oral hygiene can influence salivary metabolite profiles, which may indicate oral health status and disease onset.

Head and neck cancers (HNCs) account for 4-5% of all malignancies globally, and salivary metabolites are emerging as potential diagnostic biomarkers for these cancers.

Incorporating fermented foods like yogurt and kombucha can help replenish beneficial microbes in the gut, promoting overall health.

Daily physical activity and adequate sleep are crucial for gut health, supporting metabolism and the microbiome's connection to the circadian rhythm.

Maintaining a healthy gut involves consuming fiber-rich foods while reducing sugar and fat intake, as lifestyle choices significantly influence gut health.
