During the 21st century, China has been experiencing an era of rapid nutritional transformation. The traditional Chinese diet, rich in carbohydrates and vegetable fibers, has been increasingly replaced by refined foods and a more Western-style diet (Tian & Wang, 2019). These steadily spreading eating habits, entailing the consumption of refined saturated fat-rich foods as contrasted with vegetable fibers are promoting obesity and metabolic syndromes/ diseases (dyslipidemias, insulin resistance, diabetes), steatohepatitis, and cardiovascular illnesses (Hosoi et al., 2016;Lindroos et al., 2021).Typically, microbes in the cecum and colon portions of the gut metabolize vegetable fibers into acetic, propionic, and butyric acids, altogether indicated as short-chain fatty acids (SCFAs) (Barber et al., 2020;Cheng et al., 2020). In their turn, SCFAs interact with enteroendocrine L cell receptors whose activation induces the tyrosine-tyrosine (PYY) peptide release (Farzi et al., 2021).
