Mark your calendars! Whole Grain Sampling Day is Wednesday, March 31, 2021.This year we’re calling on you to help us share the goodness of whole grains with those who need it most. Sign up to donate whole grain items to your local food bank or other food-related charity of choice. You choose what and how much to donate and where to send it. We’ll add your donation to our map to show all the places where whole grains are being shared.
