The rate of blood glucose decline during the SITT, which reflects insulin sensitivity (Figure 2), was
also comparable between the two groups (−0.81%/min vs. −1.05%/min, p = 0.29) at baseline.
After 2 months of intervention, the rate of blood glucose decrease during SITT was significantly
greater in the spirulina group (−2.63%/min vs. −1.68%/min, p = 0.005) compared to the soyabeans
group (Figure 3).
