By Janet Colston In 2020 we spent a lot of time reflecting on functional foods from crops that we grow in controlled environments analyzing how they benefit human health.

By Janet Colston, PhD Raspberries and blackberries are among the fastest growing fruit categories in the U.S. in the last 5 years according to analysts at RaboResearch Food & Agribusiness [1].
