RDi

RDI is an acronym used in several different fields, with nutrition-based and policy-oriented meanings being the most common. In nutrition, RDI stands for Recommended Daily Intake. It refers to reference amounts of nutrients that are used to gauge whether a person’s daily consumption meets general guidelines. On nutrition labels, the RDI (or historical references to RDIs) helps consumers compare a product’s nutrient content against daily needs. Values for each nutrient vary by country and by nutrient, and some jurisdictions have moved toward different labeling conventions while others retain RDI as a reference point.

In policy and business contexts, RDI often stands for Research, Development and Innovation. This usage describes the combined activities of basic research, the development of new products or processes, and efforts to bring innovations to market. It is commonly found in European policy documents, government funding programs, and corporate reporting that group research, development, and innovation under a single umbrella. In French-language materials, the phrase Recherche, Développement et Innovation is sometimes abbreviated as RDI.

Other, less common uses of RDI may appear in specialized fields such as information technology or organizational branding, where the acronym can denote project names, interfaces, or specific concepts unique to a sector. Because the meaning of RDI varies by context, readers should rely on accompanying text to determine which definition is intended.
