How the ranking works

Each row is one product in one package size, with the shelf price and the protein figure from its nutrition label. Total protein is the package size times the protein per 100 g (or per piece for eggs and multipacks). Dividing the price by that total gives the price of one gram of protein, and the table sorts by it. A food that looks cheap per kilo can still be expensive protein if little of it is protein.

Prices come from shelf labels and receipts, and each row keeps the date it entered the table, so check the date before relying on a price.
