Scavenger receptor class B member 1 (SR-B1) is a multiligand receptor with a broad range of functions spanning from the uptake of cholesteryl esters from high-density lipoproteins (HDLs) and transport of micronutrients such as fat-soluble vitamins and carotenoids across cell membranes to roles in tumor progression, pathogen recognition, and inflammatory responses. As a target of exposome factors such as environmental stressors and unhealthy lifestyle choices, as well as aging, dysregulated expression and activity of SR-B1 can negatively impact human health. Intriguingly, not only is SR-B1 a major determinant of nutrient homeostasis and, hence, metabolic health status, but these same nutrients and some phytochemicals have also demonstrated their ability to modulate SR-B1. Therefore, an integrated approach that, taking into account human health, nutrition, and food technology sciences, aims to produce foods with health-promoting effects should take advantage of the multifaceted properties of SR-B1. Improved functional foods and novel nanoparticle-based delivery systems, rich in nutrients and phytochemicals, with precise targeting to SR-B1 in specific tissues or structures could represent a strategic advance to improve human health and promote well-being.
