it/Human Nutrition Unit
Propose a simple and efficient lever: the three golden rules for healhty, ethical and sustainable food systems.
Evidence show that the protective diet for human health, animal biodiversity and well-being, and environment follows the rule of the 3V for “Végétal, Vrai, Varié”: Végétal (Plant-based foods): maximum 15% daily animal calories; Vrai (Real food): maximum 15% daily ultra-processed calories; Varié (Varied foods): among real foods eat diversified, if possible organic, local and seasonal. Thus, decreasing ultra-processed food consumption has an immediate positive impact on global food system sustainability, notably protecting small farmers, culinary tradition, socioeconomics, environment, biodiversity
