How a city food page works

Overview

A clear explanation of the value and what it means.

A city food page shows the available price entry, calculated costs, comparisons with other cities and related foods.

How it is calculated

The formula or method behind the calculation.

city_product_page = product + city + available price row + calculated metrics

When there is no entry for a food and city, FATSL shows that the data is missing and does not substitute another value.

FATSL leaves the result unavailable if an input is missing or a zero value would require division by zero.

Example

A worked example using a food in the FATSL reference guide.

For example, a buckwheat page for Moscow can show the price per base unit and costs per 100 g, per 100 kcal and per 10 g of protein when the required data is available.

Example	kcal	Protein	Fat	Carbs	100 g	100 kcal	10 g protein
Buckwheat	346,0 kcal	11,7 g	2,7 g	75,0 g	no data	no data	no data

Use this on FATSL

Limitations

Keep these limitations in mind when using the values.

Values may differ by pack, brand, food state and preparation method.
Missing values are not filled in with guesses.
For your own purchase, the receipt or pack price is more accurate.
FATSL does not provide medical advice or make claims about a food’s health benefits.
