What a portion report means
A report records the amount one contributor selected for one identified product. It is user-reported PerBiscuit data, not a claim about every purchaser and not dietary advice.
How to contribute
You can submit a portion from the homepage without creating an account. A free profile can link your reports to a product trail and helps PerBiscuit identify distinct contributing sessions.
When aggregates are published
Product-level community statistics remain pending until the relevant evidence threshold is met. The proposed Serving Match Score requires at least 30 valid reports from 20 distinct sessions across 30 days.
Published results will show the sample size, collection dates, median, uncertainty and key exclusions. Products with insufficient data will be marked pending.
Known limitations
Contributors are self-selected, so the sample may differ from the wider population. Reports can also be affected by product matching, unit entry and repeat submissions.
