Figure 1.

The precision nutrition (PN) network. PN is shown in this figure as a synergistic network with food composition data at its core. Bidirectional arrows connecting the icons represent the constant flow of both PN and food and nutrient data. Over time, these relationships remain tightly connected as data expand, understanding improves, and an individual changes. The “professional” icon represents experts in nutrition and medicine and AI-based algorithms that work directly with an individual. “Your personal code” represents all descriptive data, including but not limited to genomics, metabolomics, and human and microbiota phenomics, along with social and anthropometric data on eating behavior, physical activity, and economic and demographic data. “Optimal requirements” are specific nutrient requirements for an individual and are determined by one’s personal code. Personalized dietary recommendations, or a “personalized diet,” are the goal of PN, wherein the professional, the individual’s personal code, and optimal requirements are factored into a dietary plan best suited to provide the best tasting, achievable diet for optimal health.
