The study sounded really vague.
However, when getting a quote from a nearby rent a quote scientist, a bit of full (or even limited) disclosure on them might help people evaluate their comments.
.. e.g. how many million Tom Sanders has received from Tate & Lyle.
Obviously, massive funding from companies involved in all things sugary, does not necessarily mean a scientist is (knowingly or subconsciously) influenced, but transparency is a good thing.
(Govt is notoriously poor on funding basic research these days, so often industry has to be a cash source for scientists, though that carries risk of been seen as mouthpiece for sugary / fatty/ whatever food company gives you funding)
