IL6 and type 2 diabetes mellitus: In T2DM patients, yam gruel therapy (the concentration used is 0.5 g/mL made by 150 g yam and 300 mL water, taking yam gruel daily in the morning for 12 weeks) reduces fasting blood glucose and 2-hour postprandial blood glucose with the actions of modulating gut microflora, increasing the serum levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), while decreasing blood high-sensitivity C-reactive protein (hs-CRP) and serum interleukin-6 (IL-6) levels (Pang et al., 2017a; Pang et al., 2017b; Pang et al., 2017c; He et al., 2022).
