Our origins

Our Nutrition division is above all the story of passionate people driven by an entrepreneurial mindset, a collaborative spirit and a philosophy of responsibility.

Created in 1990 as "Diana" from the synergy of different businesses, Nutrition roots go back to 1952 in Brittany, France, where a miller called Jean Guyomarc'h launched his company specialized in food products for poultry.

A passionate innovator, he constantly sought to develop new products, pushing his exploration further and further to turn co-products into natural, valuable food extracts. It was, at that time already, an avant-garde approach to sustainability.
