1. Introduction

Individuals feature unique glycemic reactions to exactly the same foods. (Bashiardes et al., 2018) Unsatisfactory adjustment to public dietary guidance and separate health feedback are not adequately displayed by population averages, because nonspecific public health recommendations are low on importance for people, personally and medically. (Michel and Burbidge, 2019) The main target of public health advice associated with the hindrance of food-related chronic disease is the choosing of nutritious dietary models. (Laddu and Hauser, 2019)

2. Conceptual Framework and Literature Review

Genome and microbiome information may elucidate particular clinical characteristics. (Bashiardes et al., 2018) A person's regime and environment may shape disease predisposition by influencing the expression of genes related to critical metabolic routes. (Laddu and Hauser, 2019) The developments in the knowledge base of the intricate synergies among genotype, nutritional therapy, style of living, and environment bring about modifications (Androniceanu, 2017; Bratu, 2017; Caruso et al., 2017; Faggianelli et al., 2018; Ionescu, 2018; Massey et al., 2018; Nica, 2017; Ralston et al., 2018; Smith and Stirling, 2018) in present medical routine to eventually generate personalized nutrition advice for health and risk evaluation, as intakes and dietary supplements distinctively impact the good physical condition of persons. An individual's gut microbiota is decisive in encompassing the multiple-functional links with elaborate metabolic processes entailed in preserving cellular homeostasis. (Aruoma et al., 2019) The big data tools of personalized nutrition are facilitating the advancement of more customized and predictive dietary advice and interventions against energy imbalance and metabolic disease that may alter how individuals make food choices and significantly enhance population health. (O'Sullivan et al., 2018)

3. Methodology and Empirical Analysis

Using and replicating data from ABS, CCHS, CRN, Euromonitor International, Ipsos Public Affairs, Mintel, and Statista, I performed analyses and made estimates regarding U.S. people who take nutritional supplements and top reasons for taking them (%, by age group and sex), healthy habits of U.S. adult supplement users vs. non-users (%), U.S. adults who use an app to track their diet and nutrition (%), proportion of calories from fresh food, packaged food, soft drinks, and alcoholic drinks (% of total calories purchased), prevalence of inadequate fruit and vegetable intake (%, age groups), and prevalence of usual intakes of sodium exceeding the tolerable upper intake level (%, by sex and age groups). The data for this article were collected through an online survey questionnaire and were analyzed via structural equation modeling on a sample of 4,800 respondents.

4. Results and Discussion

Personalized algorithms facilitate the precise prediction of glycemic reactions to foods. (Bashiardes et al., 2018) Personalized nutrition can explain findings concerning heterogeneity in nutrient metabolism between subcategories and the interindividual inconsistency in the feedback to dietary interventions, providing particular, applicable dietary treatment contingent on distinct nutritional phenotype, generated from the synthesis of genetics, metabolic profile, and environmental components (Benedikter et al., 2017; Bratu, 2018; Douglas, 2018; Freeman-Moir, 2017; Lupu-Stanescu, 2018; Mihaila, 2017; Popescu Ljungholm, 2017; Schinckus, 2018; Tanankem Voufo et al., 2017) for the purpose of preventing and treating chronic disease. (Laddu and Hauser, 2019) User's genetic composition is employed in the manufacturing operation of hyper-personalized consumer products (Banerjee et al., 2016; Carter and Yeo, 2018; Drugau-Constantin, 2018; Hurd, 2016; Machan, 2016a, b; Mirica (Dumitrescu), 2018; Popescu Ljungholm, 2018; Sharp, 2016) that prioritize refinement and exceptionality, and reap high prices. (Rosenbaum et al., 2019) (Tables 1-9)

5. Conclusions and Implications

Personalized nutrition employs data on separate features to advance targeted nutritional guidance, foods, or services to help individuals in attaining a perpetual dietary alteration in behavior that is health-giving (Ordovas et al., 2018), improving dietary metabolic syndrome treatment. (Bashiardes et al., 2018) As a pretreatment gut microbiota biomarker, enterotypes may eventually be a relevant component in personalized nutrition and obesity management. (Christensen et al., 2018) The prevalence and acuteness of ordinary and expensive human diseases may be determined by nutritional vulnerabilities and inadequacies that alter the epigenome, and the predominant intervals of exposure are the periconception phase and early prepubescence. (Skinner et al., 2019)
