Nutritionists don't stop there, because they can't: they have to manufacture complication, to justify the existence of their profession. These new nutritionists have a major commercial problem with the evidence. There's nothing very professional or proprietary about 'Eat your greens,' so they have had to push things further. But unfortunately for them, the technical, confusing, overcomplicated, tinkering interventions that they promote - the enzymes, the exotic berries - are very frequently not supported by convincing evidence.
