OPEN A DRAWER
Six papers, read slowly. Keep the preparation, people, comparison and uncertainty beside each finding.
Abstract-based reading · consulted October 17, 2026. A selected teaching example, not a systematic review or dietary recommendation. Full-text methods, funding, registration and risk of bias have not been assessed.
These papers were selected to practise reading dose, preparation, substitution, and mixed or null findings. They are a starting shelf, not a ranking of foods.
Set two papers beside each other →28 older adults; mean age 75.
Testing at 1, 2.5, 4 and 6 hours; seven-day washouts.A reading card about dose, short-term tasks, and the distance between a result and a promise.
192 adults with LDL cholesterol of 130–190 mg/dL.
Six months; fasting lipids measured monthly.Read a trial that keeps raw garlic, two supplements, and its comparison group in view.
Two groups of 24 healthy adults.
Single-meal, postprandial testing.A meal-substitution study, read with the food on both sides of the comparison kept visible.
34 volunteers in one experiment; 40 in the other.
11 days of supplementation; follow-up after eccentric elbow exercise.A card about exercise-induced soreness, separate experiments, and the limits of a familiar ingredient.
367 randomized; 345 completed. Baseline LDL: 3.0–5.0 mmol/L.
Four weeks.A cereal trial that invites a closer look at fibre structure, a blood marker, and uncertainty.
12 healthy volunteers recruited; 11 completed.
Four breakfast visits, with postmeal measures and subsequent food intake.Glucose, insulin, appetite, and taste did not tell a single simple story in this small bread study.
