Precision Nutrition for Cardiovascular Disease Prevention

Abstract

Background: Cardiovascular diseases (CVD) are the leading cause of death globally, making their prevention a major challenge for modern society. For decades, treatments aimed at reducing CVD risk factors through nutritional recommendations and medications have had variable success. One of the main reasons behind this is the interindividual variability in response to drugs and nutritional interventions. The development of genomics has allowed the discovery of genetic variants influencing drug and food response, leading to more personalized treatments in the form of precision medicine and precision nutrition. The latter is based on the principle that one diet does not fit all and the need to stratify individuals into subgroups based on their response to nutrients. Despite showing great promise in pushing forward the field of nutrition, health professionals have very little knowledge of precision nutrition, even though the general population is showing interest in more personalized nutritional guidance. Summary: This review aims to provide an overview of key sources of interindividual variability observed in CVD risk factors in response to nutritional interventions. Despite some limitations, genetic testing is a mature predictive tool that should be at the forefront of tailored nutrition recommendations for CVD prevention. Although the epigenome-diet relationship shows great promise, it is still too early in its development to allow for its clinical deployment. Metabolomics has the potential to enhance genetic testing by complementing traditional self-reported dietary intake instruments as well as a very promising metabotyping method. Microbiome phenotyping, despite its complexity, provides a wealth of information on the health status of the host and its response to nutrients. Finally, current applications are discussed and an outline of the required steps for a successful implementation of precision nutrition in clinical practice as a tool for CVD prevention is presented. Key Messages: Precision nutrition is the cornerstone of a promising approach offering targeted nutritional recommendations for CVD prevention.

“…Omega-3 fatty acids, found in fatty fish and supplements, have been shown to reduce triglyceride levels and lower the risk of heart disease [31]. Plant sterols, found in certain margarines and supplements, can also help lower cholesterol levels [32].…”

A pilot retrospective study of a physician-directed and genomics-based model for precision lifestyle medicine

“…The SNP chip used in this study was designed in house on a standard GSA array adding approximately 6,000 additional SNPs to meet requirements supporting multiple validated polygenomic scores along with clinically relevant individual SNPs. Polygenic risk scores were taken from the available clinical literature and include cardiovascular, dementia, exercise, and nutrition, among others (13)(14)(15)(16)(17). Individual SNPs were chosen based on literature review and had to meet internal requirements for clinical quality including: (1) the SNP has had consistent and significant odds ratio or positive likelihood ratio with a specific disease process, and (2) has been proven in multiple studies of adequate power and applicability to the patient population.…”
