Characterizing Precision Nutrition Discourse on Twitter: Quantitative Content Analysis

Characterizing Precision Nutrition Discourse on Twitter: Quantitative Content Analysis

A related concept, nutrigenomics, is broadly understood as the study of gene-diet interactions but is most often used to refer more specifically to the effects of nutrients on the genome, such as on gene expression [6]. Therefore, in one sense, nutrigenetics can be subsumed under the broader term nutrigenomics, but in practice, most often the terms are discussed as complementary areas of study that both comprise precision nutrition (Figure 1). We used these terms in the latter way in this study.

Given that the interaction of nutrients with DNA can impact nutritional status and the development of complex diseases, nutritional genomics (nutrigenomics) has become increasingly important in nutrition practice. Nutrigenomics encompasses nutrigenetics, which investigates the effect of genetic variation on nutrient bioavailability and metabolism, and nutrigenomics, which examines how nutrients and bioactive food compounds affect human health through epigenetic modifications [1-5].

Nutritional genomics, which encompasses nutrigenomics and nutrigenetics, improves on current health practices by enabling more tailored nutritional advice targeted to individual needs. Nutrigenetics investigates the effect of genetic variation on nutrient bioavailability and metabolism. Nutrigenomics further investigates how nutrients and bioactive food compounds affect human health through epigenetic modifications [6-10].
