An<i>in Vivo</i>Study of the Antioxidant Potentials of a Plant Food Concentrate
Bibliographic record
Abstract
OBJECTIVE: A plant food concentrate (PF) is a source of antioxidants. Its influence on antioxidant status has never been studied. The present longitudinal study investigated the antioxidant and lipidemic responses in 15 moderately hypercholesterolemic (>5.2 mmol/L) male subjects to the supplemental intakes of PF. METHODS: The participants underwent a two-week period where any previous supplemental intakes were withdrawn. This was followed by a two-week baseline period at entry (control). The baseline period was followed by taking PF concentrate (8.5 g twice daily) for two weeks followed by a washout period for two weeks. All subjects completed food frequency questionnaires at pre-supplemental (baseline) and post-PF period. Fasting heparinized and EDTA blood samples were collected at the end of each period. Erythrocyte superoxide dismutase (SOD), whole blood glutathione peroxidase (GPX) and plasma concentrations of zinc and copper, along with plasma levels of lipids, were determined. RESULTS: The PF supplement contributed significantly to the daily intakes of total dietary fiber. The zinc and copper-dependent SOD but not GPX activity were significantly elevated. The total and LDL-cholesterol concentrations in the plasma were significantly decreased while the ratio of HDL/LDL cholesterol was increased post-PF intake. CONCLUSIONS: These results indicate that the antioxidant and cholesterol status of moderately hypercholesterolemic subjects can be potentially improved with the supplemental intake of PF concentrate.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
