Competing Interests

The Wageningen Centre for Food Sciences (WCFS) is an alliance of six industrial partners (AVEBE, Cosun, CSM, DSM, Unilever, and NZO) and four research organizations (Wageningen University and Research Centre, Maastricht University, NIZO Food Research, and TNO Quality of Life). Forty-seven percent of funding comes from the Dutch government, 29% from the industrial partners, and 24% from the research institutes. The partners have no say over the mode or content of publications resulting from work at WCFS but have the right to seek patent protection so that findings can be commercialized. MBK is a member of the editorial board of PLoS Medicine.
