Evidence-based health tools and expert articles for smarter, healthier living.
An engineer's look at betaine (trimethylglycine) using real USDA FoodData Central records, FDC IDs included, and why the famous wheat-bran value is missing from the main database.
An engineer's look at fisetin in USDA data: why strawberries dominate, how the flavonoid database differs from FoodData Central's core panel, and what the senolytic research really claims.
An engineer's look at how the USDA FoodData Central database tracks choline (nutrient ID 421) — top food sources, NIH Adequate Intake values, and the data caveats behind a single 'choline, total' field.
An engineer-builder's look at the USDA Flavonoid Database r3.3: where EGCG and catechins actually live in tea, cocoa, apples, and berries, what the human research supports, and what aggregating this data for 1,465+ foods on HealthSavvyGuide revealed about quality, gaps, and brewing variability.
An engineer's look at the USDA polyphenol data behind resveratrol — what red grapes, peanuts, and red wine actually deliver per 100 g, and why the numbers fall far short of clinical-trial doses. Informational only, not medical advice.
An engineer's aggregation of USDA FoodData Central inulin data — which whole foods actually deliver meaningful prebiotic fiber, where the published numbers diverge, and the side-effect ceiling most articles skip.
