Better foods for humans is one of Avril’s sustainable development commitments. This means constantly improving the quantity and quality of its products. As a major actor in this area, in 2010 Lesieur signed a charter on voluntary commitments to nutritional advances with the authorities in the context of the French National Nutrition and Health Program (PNNS), fixing precise goals to be achieved within three years.  100% of these goals were indeed attained, notably in terms of improving the nutritional profile of its products. As the inventor of ISIO 4, the first combined table oil to offer a significant Omega 3 content, Lesieur invests constantly in research in order to ally culinary trends with scientific advances.
