That vegans - in the comparison to a conventional nutrition - take less of certain nutrients without food addition, is well-known. One can therefore ask why such a study is necessary. Possibly the chapter "Funding" of the study provides a hint: The work is supported by [...] Wellcome Trust Our Planet Our Health (Livestock, Environment, and People, LEAP 205212/Z/16/Z); see https://www.leap.ox.ac.uk/home https://www.leap.ox.ac.uk/home.
