Identify the exact claim
Rewrite the sentence beside the citation in plain language. Is it reporting food composition, a recommended reference value, an association, a causal effect, or current product behavior? A source can be reputable and still be the wrong evidence type. Breaking a broad sentence into smaller claims often reveals that one link supports only part of what was written.
Match the source type to the job
Government food-composition databases can support reference nutrient values. Official guidelines can support population-level recommendations. Systematic reviews summarize a body of studies, while randomized trials test defined interventions under specified conditions. First-party product documentation is appropriate for what a company currently says or exposes, but it is not independent evidence that the product is more accurate or effective.
Check directness
Compare the source's food, population, setting, exposure or intervention, comparator, and outcome with the claim. A study of a supplement is not automatically evidence about a meal; a group-average association is not an individual prediction; and a nutrient value per 100 grams does not establish the weight of a photographed serving. The farther the match drifts, the more clearly interpretation should be labeled.
Inspect the date and version
Product capabilities, guidelines, databases, and regulations can change. Look for the publication date, update date, dataset release, and access date. For a living product page, confirm that the cited feature still appears in the current version. For data, prefer a stable identifier and release context so later readers can distinguish a corrected source from the one originally used.
Read beyond the abstract or headline
Find the methods, limitations, and definition of the outcome before relying on a result. Note sample size, missing data, duration, and whether the analysis was planned in advance. A statistically notable result may still be small, uncertain, or poorly matched to the decision at hand. When the full source is unavailable, describe the evidence boundary instead of filling the gap with confidence.
Keep inference and disagreement visible
When Feast draws a practical conclusion beyond a source's exact wording, that step should be labeled as editorial interpretation. If authoritative sources disagree, present the scope of the disagreement and avoid manufacturing a single answer. A citation is a trail a reader can audit; it is not a badge that makes every nearby statement true.
