Sounds very hermetic as a rejoinder. This way the cigarette industry could promote healthy smoking, because you know, scientists.
But you are right, lets have a closer look:
"Ian Givens is recipient of research grants from UK Biotechnology and Biological Sciences Research Council (BBSRC), UK Medical Research Council (MRC), Arla Foods UK, AAK-UK (both in kind), The Barham Benevolent Foundation, Volac UK, DSM Switzerland and Global Dairy Platform. He is a consultant for The Bio-competence Centre of Healthy Dairy Products, Tartu, Estonia, and in the recent past for The Dairy Council (London). Arne Astrup is recipient of research grants from Arla Foods, DK; Danish Dairy Research Foundation; Global Dairy Platform; Danish Agriculture & Food Council; GEIE European Milk Forum, France. He is member of advisory boards for Dutch Beer Knowledge Institute, NL; IKEA, SV; Lucozade Ribena Suntory Ltd, UK; McCain Foods Limited, USA; McDonald's, USA; Weight Watchers, USA. He is a consultant for Nestlé Research Center, Switzerland; Nongfu Spring Water, China. Astrup receives honoraria as Associate Editor of American Journal of Clinical Nutrition, and for membership of the Editorial Boards of Annals of Nutrition and Metabolism and Annual Review of Nutrition. He is recipient of travel expenses and/or modest honoraria (<$2,000) for lectures given at meetings supported by corporate sponsors. He received financial support from dairy organisations for attendance at the Eurofed Lipids Congress (2014) in France and the meeting of The Federation of European Nutrition Societies (2015) in Germany."
So basically they covered Givens and Astrup.
The very fact that scientific research has its ethics and is bound to be open to conflicts of interest should make everyone skeptical of the outcome: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2700754/
