BOSTON — An all-day session aimed at giving Grain Foods Foundation investors a comprehensive look at G.F.F. activities and research will be held June 2 in Boston.

Companies that support the foundation are invited to send staff members to GFF Unpacked, a one-day event targeted toward marketing, communications, social media, public relations and nutrition professionals. The gathering will convene at the downtown Boston offices of G.F.F.’s longtime agency MullenLowe.

Topics to be explored during the event will include G.F.F.’s spheres of influence, including media relations and the group’s scientific advisory board. New grains research and consumer-facing resources generated by the organization will be shared to help investors “tell the grains science story.” The group’s creative vision, which drives new social media tools and campaigns, also will be shared.
