আমরা কনটেন্ট আর সংখ্যাগুলো কীভাবে প্রস্তুত করি

CalCalc content is written to explain what a metric means, how to use a tool, and where interpretation usually goes wrong in real life.

We avoid pretending that informational pages are medical advice, and we do not frame calculator estimates as perfect precision.

Food pages and derived summaries start from Open Food Facts data and are normalized before publication so names, portions, and nutrient fields are easier to read and compare.

If a page conflicts with the package in your hand or a newer local label, trust the package first.

Methodology pages and practical guides are reviewed when calculation logic changes, wording needs clarification, or the source set behind an explanation is updated.

Where freshness matters, we show a last-updated date so readers can judge whether a page is still current enough for the task.

The calculators provide a starting estimate, not a diagnosis. Real calorie needs depend on behavior, tracking accuracy, weight trend, and day-to-day context.

The food catalog is useful for comparison and planning, but it cannot guarantee that every page is fresher or more precise than the package sold in your market.
