From the article...What characterises ultra-processed foods is that they are so altered that it can be hard to recognise the underlying ingredients. These are concoctions of concoctions, engineered from ingredients that are already highly refined, such as cheap vegetable oils, flours, whey proteins and sugars, which are then whipped up into something more appetising with the help of industrial additives such as emulsifiers.
What a load of unwarranted assumptions in that paragraph! The original meaning of the phrase "begging the question" was in debate; where a debater would frame the subject in a way that it assumes that his premise is valid. The above is a pretty good example of that.
A pate, terrine, any bread, omelet, souffle, pizza, any pureed soup and many other dishes are all "so altered that it can be hard to recognize the underlying ingredients".
