Beetroot Nitrate Cognition Randomized TrialDynamic cerebral autoregulation (dCA) is an important mechanism of cerebrovascular blood flow regulation and serves as a protective mechanism for the brain against large fluctuations in blood pressure that can result in hyper‐ and hypo‐perfusion of vulnerable brain regions (Claassen et al., ).2Gosalia Jigar (2026)A pilot randomized controlled trial of the effects of dietary nitrate supplementation on dynamic cerebral autoregulation in older adults with metabolic syndrome
Beetroot Nitrate Cognition Randomized TrialImpaired dCA may be a primary mechanism contributing to increased risk of cognitive decline in MetS and can be targeted therapeutically.2Gosalia Jigar (2026)A pilot randomized controlled trial of the effects of dietary nitrate supplementation on dynamic cerebral autoregulation in older adults with metabolic syndrome
Beetroot Nitrate Cognition Randomized TrialReduced NO bioavailability promotes inflammation, oxidative stress, and endothelial dysfunction, all of which negatively impact cerebral microvascular function and subsequent dCA (Deanfield et al., ; Delgado Spicuzza et al., ; Mcnally et al., ; Picón‐pagès et al., ; Seals et al., ; Stephan et al., ).2Gosalia Jigar (2026)A pilot randomized controlled trial of the effects of dietary nitrate supplementation on dynamic cerebral autoregulation in older adults with metabolic syndrome

Beetroot Nitrate Cognition Randomized TrialThis review aims to define the mechanistic, dietary and host conditions under which nitrate bioactivation becomes functionally relevant, with particular attention to its microbial determinants and to the level of inference the evidence actually supports.4Buzatu GD (2026)Dietary Nitrate Bioactivation at the Diet-Microbiota-Host Interface: The Enterosalivary Cycle, Food Matrix, Microbial Determinants and Health Implications-A Narrative Review Supported by a Structured Literature Search.
Beetroot Nitrate Cognition Randomized TrialThe oral microbiota is the principal microbial determinant of the response, whereas the gut microbiota acts as a context-dependent modifier of intestinal redox tone, barrier function and microbial ecology, supported by markedly weaker human evidence.4Buzatu GD (2026)Dietary Nitrate Bioactivation at the Diet-Microbiota-Host Interface: The Enterosalivary Cycle, Food Matrix, Microbial Determinants and Health Implications-A Narrative Review Supported by a Structured Literature Search.
Beetroot Nitrate Cognition Randomized TrialConclusions: We propose the Source-Matrix-Microbiota-Host (SMMH) framework, in which biological impact depends on the interaction between dietary source and dose, food matrix, microbial nitrate-reducing capacity and host susceptibility, rather than on nitrate dose alone, and in which pathway-level, physiological and clinical evidence are kept explicitly distinct.4Buzatu GD (2026)Dietary Nitrate Bioactivation at the Diet-Microbiota-Host Interface: The Enterosalivary Cycle, Food Matrix, Microbial Determinants and Health Implications-A Narrative Review Supported by a Structured Literature Search.
Beetroot Nitrate Cognition Randomized TrialBackground/Objectives: Dietary nitrate, long framed through food-safety concerns about N-nitroso compound formation, is now also recognised as a substrate of the nitrate-nitrite-nitric oxide pathway.4Buzatu GD (2026)Dietary Nitrate Bioactivation at the Diet-Microbiota-Host Interface: The Enterosalivary Cycle, Food Matrix, Microbial Determinants and Health Implications-A Narrative Review Supported by a Structured Literature Search.
