The easy fix is not to put sugar, in it's many and modified/synthetic forms into everything.
It'd also be nice if they only used natural fats, and did not process the hell out of everything to make an extra 5p per tonne of product.
Maybe take it as a hint that if, after preparation, in the commercial taste kitchens, something tastes like &*(&, then maybe people should not be eating it, and not as an excuse to fill it up with other things to make it more palatable.
Food is supposed to have some form of nutrition, not just calories.
It appears that the vast majority of 'food', stuff sold as food anyway, is so far from being food, according to our senses, that they have to fill it with possibly 30-40 other non food things, merely to convince our bodies that it is indeed edible, enough to allow us to eat it anyway.
They also seem to have perfected the 'art' of making such things addictive, so addictive non food, that contains nothing but calories and other nice things that muck up out bodies - recipe for a world full of healthy thin people, not.
..and in answer to the above point of shops no longer selling things that always used to be 'food', and other things.
Even over the last 2 years it has become impossible for me to buy, from supermarkets online, many items that I have eaten for years - in a lot of cases simple, natural ingredients. Other things like cleaning products (e.g. white vinegar, a really cheap cleaning constituent) are either, in most cases, unavailable, or repackaged and super expensive (e.g. again white vinegar can now only be bought in 500ml extremely dilute form in a supermarket, for about £1, in 5L containers it's around £4, and that's a significant hike, when the supermarkets used ot sell it in larger containers it worked out under half that price).
Many things that can still be bought online, and not in supermarkets, any more, work out 5-10 times the price on amazon or health food shops compared with what supermarkets charged, when they sold it.
