Shall I cover that? Thank you. So, at the moment, the majority of the manufacturing requirements placed on the industry are non-mandatory. This is generally approached through a voluntary engagement approach. As Kate has mentioned, reformulation is one part, and one of the things I would say, having been involved in the reformulation journey for a number of years, is that there are different models that work or have worked in better ways than others.
So, we, for example, have a very detailed salt structure and matrix, which have targets for 90-odd food categories. This is very clear, it's enabled us to communicate to suppliers in a very, very clear way; all the suppliers are getting the same information for every single retailer. I would say the salt reformulation strategy, although arguably slow—and we also have to bear in mind that we have had a couple of challenges with going too far in products, and therefore turning people off from the consumption of those products et cetera—I would say overall, it has been a success.
There have been other reformulation programmes, for example the sugar one, where we have made great strides on a number of categories, for example breakfast cereals, yoghurts. On other categories, it's been a lot more challenging. I think there are a number of elements that have made it very challenging. I think the first one being that, again, we don't have the detailed guidance that we've got with salt. So, people have had to trial and test—with different resources, obviously there have been different outcomes—what is possible in terms of the reduction of sugar from some of those categories.
And the other element that I think is challenging with elements like sugar is that they are products—Kate alluded to chocolate, but the same thing applies to biscuits, cakes et cetera—where you might be able to reduce sugar slightly, but it is an inherent ingredient within those types of products. They're indulging; sugar applies—not only is it important for the flavour profile of the product, but it also has a structural function. So, we in retail believe that if there was to be legislation pinning down the composition of certain products, we would have a similar effect to what has happened in South Africa, where there are a number of companies that went out of business because they just couldn't meet the targets, and it resulted in the Government withdrawing some of that legislation, because they felt it was just not possible to achieve many of the targets that they set. Alternatively, if you were to set targets that are achievable, they would have to be set so high that you wouldn't actually see the level of reformulation that has already happened by some companies.
We feel that voluntary approaches are still what works. I would call on the Government for some more robust guidance, because at the moment I don't think we have the necessary tools to be able to guide even companies the size of my members, but actually smaller companies, in that reformulation journey. We should learn from experience and we should have more detailed guidance. But I think in terms of how we can achieve better results, we feel in the retail industry—and we're better placed, perhaps, than individual manufacturers—I think we're moving into an area where a lot of the composition of products is being optimised, and we really have to move to talk about healthier balanced diets, healthier balanced baskets, talking of consuming certain categories, not necessarily in ways that they have been reformulated, but in lower quantities and less frequent.
