In all, the study found, there were 52 transport and/or production processes needed to combine the various products together to make a single bottle of sauce. This WAS NOT including the crude oil being brought from whenever it first came from, the process of refining the oil, the resources involved in processing and transporting the sugar, salt, vinegar and other ingredients to Sweden, and the journey made (probably by car) to buy the product from the supermarket and return it home. Food production capabilities will see deeper, and deeper crisis, as energy supplies dwindle.
