Dental cavities form when bacteria living on teeth repeatedly turn sugar into acid, lowering the local pH and, over time, leading to mineral loss in the tooth. Scientists have suspected that some nutrients might help counter this process, but it has been unclear whether they can make dental plaque less harmful by changing how it behaves rather than simply removing bacteria. The study involved ten adults with active tooth decay, each wearing a custom lower-jaw splint that held small glass surfaces with a texture similar to enamel (the protective outer covering of teeth), where plaque could gro... microbes sugar dental

Watch nowA new study shows how omega-3 fatty acids increase nitric oxide production – a molecule that supports and enhances athletic performance. Endurance athletes who consumed supplemental omega-3s had higher blood levels of arginine, an amino acid involved in nitric oxide production. The study involved 26 men who underwent endurance training for 12 weeks. Half of the men took an omega-3 supplement (approximately 3 grams daily) for the duration of the training, while the other half did not. Researchers measured their Omega-3 Indices (https://pubmed.ncbi.nlm.nih.gov/15208005/) and blood amino acid lev... exercise omega-3 nitric oxide

Watch nowTau is a protein found in the brain. It plays critical roles in nerve axon stability and the transport of mitochondria, lipids, and cellular metabolites in the brain. New evidence suggests that high dietary salt intake increases the formation of tau tangles. Tau tangles are abnormal aggregates of tau protein that form when tau undergoes hyperphosphorylation. The formation of tau tangles is an early event in the pathogenesis of several neurodegenerative disorders, including Parkinson’s disease and Alzheimer’s disease. The authors of the study fed mice either a normal diet or a high salt diet ...

It also participates in many biological processes driving pregnancy outcomes, maintaining bone mineral density and muscle mass in older adults, improving neurological function, and aiding the immune system to fight cancer. Creatine is best known for its widespread use as a dietary supplement to enhance physical performance. Creatine uptake, synthesis, storage, and supplementation Creatine uptake Creatine can be supplied exogenously (from dietary or supplemental sources) ... metabolism neurodegeneration nutrition brain aging depression pregnancy
