But in this final phase the addition of any nutrient of concern (e.g. sugars, fats or sodium) makes the product subject to any of the warnings regardless of the nutrient the product was added with (e.g. A pre-packaged product added with sodium is a processed or ultra-processed product and if its content is above the thresholds for any of the nutrients of concern or calories it should include all corresponding warnings. Conversely, in phase 2, if a product is added with sodium, but not with other nutrients, it is not subject to the application of other warnings apart from sodium's).
