A Johns Hopkins study shows Fusobacterium nucleatum, a mouth bacterium linked to gum disease, can travel to breast tissue via the bloodstream, causing inflammation, DNA damage, and cell changes that accelerate tumor growth and spread in mouse models, with BRCA1-mutant breast cells especially vulnerable; findings suggest oral microbes may influence breast cancer risk and progression.
Researchers report a vibration-activated ceramic powder (BSCT) that uses electric-toothbrush motion to trigger whitening reactions at the tooth surface, delivering noticeable whitening after hours, while also rebuilding damaged enamel and shifting the oral microbiome toward a healthier balance in rat studies—potentially enabling at-home whitening with enamel protection.
A Danish study from Aarhus University suggests that increasing arginine levels in saliva can shift mouth biofilms from acid-producing to protective, reducing tooth decay risk. In a real-world denture-biofilm setup, arginine treatment raised pH after sugar exposure, altered the bacterial and sugar composition, and reduced acid-producing Streptococcus populations, though responses varied among individuals. Arginine appears safe and could be explored as an additive in toothpaste or mouthwash, warranting further clinical research.
A study suggests that drinking beet juice twice daily can lower blood pressure in older adults within two weeks, likely due to nitrates in beets that convert to nitric oxide, relaxing blood vessels. However, more research is needed, and beet juice should be part of a comprehensive heart-healthy lifestyle.
A study suggests that drinking beet juice twice daily may help lower blood pressure in older adults by altering oral bacteria that convert nitrates into nitric oxide, which relaxes blood vessels. Experts recommend considering beet juice as part of a heart-healthy lifestyle, but more research is needed to confirm its effectiveness and identify who may benefit most.
Scientists discovered that people with multiple sclerosis have an imbalanced oral microbiome characterized by a loss of beneficial bacteria and lower levels of the protective metabolite hypotaurine, suggesting that oral bacteria may influence immune dysregulation in MS. These findings could lead to saliva-based diagnostic tools and new treatments aimed at restoring healthy oral bacteria to support neurological health.
Scientists have discovered large, mysterious DNA segments called 'inocles' in the human mouth's microbiome, which may influence the immune system and could serve as biomarkers for diseases like cancer. These giant extrachromosomal elements were identified using advanced long-read DNA sequencing, revealing new insights into the complex relationship between oral bacteria and human health.
A study finds that certain bacteria and fungi in the mouth can increase the risk of pancreatic cancer by more than three times, highlighting the importance of good oral hygiene and potential for microbiome profiling in cancer prevention.
Research suggests that specific microbes in the mouth are linked to an increased risk of pancreatic cancer, highlighting the importance of good oral hygiene not just for teeth but potentially for cancer prevention. Certain bacteria and fungi in the mouth may access the pancreas via saliva, and their presence could serve as early indicators for cancer risk, aiding in earlier detection and intervention.
A study links the presence of 27 types of bacteria and fungi in the mouth to a more than threefold increased risk of pancreatic cancer, highlighting the potential importance of oral health in cancer prevention, although causality has not been established.
Researchers in Japan have discovered large extrachromosomal DNA elements called Inocles in the human mouth, present in about 74% of people, which may influence oral health, immunity, and disease risk. These structures help bacteria adapt to the oral environment and could serve as markers for serious diseases like cancer.
Researchers at the University of Tokyo discovered giant extrachromosomal DNA elements called Inocles in the human mouth, which may influence oral health, immunity, and disease risk, including cancer, by aiding bacterial adaptation in the oral microbiome.
A study suggests that drinking beet juice rich in nitrates may help lower blood pressure by positively altering the oral microbiome, especially in older adults, and highlights the potential benefits of incorporating nitrate-rich foods like beets, spinach, and kale into a balanced diet for heart health.
A study by the University of Exeter found that drinking nitrate-rich beetroot juice can lower blood pressure in older adults by improving vascular health and altering oral bacteria, with potential benefits for healthy aging. More research is needed, and individuals should consult healthcare providers before making dietary changes.
A study found that daily consumption of nitrate-rich beet juice can lower blood pressure in adults, especially in older individuals, by altering oral bacteria and promoting vasodilation through nitric oxide production. Beets are a nutritious vegetable that may support heart health, digestion, and athletic performance, and should be consumed regularly alongside other nitrate-rich vegetables for optimal benefits.
