A cross-sectional study developed by Akter et al. (2016) [51] reported that high PRAL and NEAP values were associated with the presence of insulin resistance (assessed by homeostasis model assessment insulin resistance—HOMA-IR and homeostasis model assessment β-cell function—HOMA-B) in 1732 apparently healthy Japanese workers, aged 19–69 years [51]. Here, PRAL is linked to Insulin resistance.
