1 What is in my food?

Manufacturers must list the ingredients for a food or drink product if it has two or more ingredients. These must be listed in order of weight, with the main ingredient first. If water has been added, that also appears in the ingredient list.

You will see that a percentage value is sometimes given for some ingredients in the list (Figure 1). Look at a few food packages and see if you can find any examples of this.
