Oat-Protein-Based Diet Lowers Blood Pressure and Prevents Cardiac Remodeling and Dysfunction in Spontaneously Hypertensive Rats
Bibliographic record
Abstract
Background/Objectives: Hypertension and its associated complications, such as cardiac remodeling and dysfunction, continue to impose a significant burden on global healthcare. Nutritional interventions have been recognized as playing a crucial role in addressing this devastating condition termed a ‘silent killer’. Plant-based proteins could potentially be utilized as a non-pharmacological strategy to combat hypertension and its related risk factors. In this study, we investigated the efficacy of an oat protein diet in managing hypertension and cardiac abnormalities. Methods: Four-week-old male spontaneously hypertensive rats (SHRs) and Wistar–Kyoto (WKY) rats were fed a regular diet with casein as a protein source or an oat-protein-based diet for 16 weeks. Twenty-week-old male SHRs showed high blood pressure (BP), cardiac remodeling, cardiac dysfunction, higher levels of markers of oxidative stress [malondialdehyde (MDA)] and inflammation [tumor necrosis factor-α (TNF-α)], as well as lower levels of a marker of vascular function (nitric oxide). Results: The oat protein diet was able to significantly lower high BP, prevent cardiac remodeling and dysfunction, improve the levels of nitric oxide, and reduce the levels of TNF-α. Oat protein, after in vitro gastrointestinal digestion, also exhibited angiotensin-converting enzyme inhibition and significantly higher antioxidant activity than casein when assessed with the 2,2-diphenyl-1-picrylhydrazyl and the iron-chelating assays in vitro. Conclusions: oat protein lowers BP and prevents cardiac remodeling and dysfunction partly via improving the levels of nitric oxide and TNF-αin SHRs. Its high antioxidant potential could contribute to the observed cardiovascular effects.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
