What is FATSLIM FATSLIM - reference sloy for comparison foods by Nutrition, calculated price-based metrikam, city rows, rankings and param foods. Sayt shows analitiku based on available data, a not magazinnuyu vitrinu.
How prices are used A price row links a food, city, unit, currency and observation date. Missing data is left empty rather than replaced with an invented price.
What price per 100 g means Price per 100 g normalizes a price row by weight. For prices per kilogram, the formula divides the value by 10 so foods are easier to compare.
Chto znachit calculated cost per 100 kcal Calculated cost per 100 kcal uses the normalized price per 100 g and calories per 100 g. No Result is shown when calories are missing or zero.
What price per 10 g of protein means Price per 10 g of protein uses the normalized price per 100 g and protein per 100 g. No Result is shown when protein or price data is missing or zero.
How rankings are used Rankings sort foods by price, carbs, protein, sugar, fat or calculated protein and calorie cost. Missing values appear last and are not replaced with invented numbers.
How food comparison is calculated Food comparison combines nutrition, a price row or an average calculation, and calculated metrics in one table. Results remain neutral: higher, lower, nearly equal or no data.
How city comparison is calculated City pages compare only rows available in FATSLIM data. A highlighted minimum is the lowest available row among selected cities, not a verified store price.
What source verification means Some nutrition values is linked with vneshnimi methodology. These value remain reference values: they may differ ot specific package, variety or method preparation.
What reference rows are Some rows support catalog coverage and navigation. They are limited reference values, not confirmation of current market conditions.
How to read FATSLIM does not provide medical advice, promise health benefits, show store baskets or claim a current store price without separate source verification.
