Effect of drinking water containing trehalose on BAT. Histological analysis of BAT (a) hematoxylin-eosin staining, × 400). Arrows (→) indicate vacuolation of BAT cells by fat deposition. Fatty degeneration scores (b) were graded as negative: 0, slightly: 1, mildly: 2, and severe: 3. Subsequently, the personal score was plotted (n = 8). Statistical analysis was performed using the nonparametric Wilcoxon test. Values show statistical significance (9b; p < 0.01 and p < 0.05). BAT: brown adipose tissue
