Figure 5. Effects of spirit vinegar and natural fermented vinegar products on epidydimal triglyceride content (A), representative findings (B), and adipocyte size (C) in rats fed a high-fat diet. Epididymal fat tissues were visualized by hematoxylin and eosin staining. Adipocyte size was measured using a microscope and quantified using an image analyzer. Values are the mean ± SE (n = 10). Bars with different letters are significantly different at p < 0.05 by Tukey’s test. N: normal diet group, HF: high-fat diet group, HF-A: high-fat diet + spirit vinegar administered group, HF-B: high-fat diet + apple vinegar administered group, HF-C: high-fat diet + brown rice vinegar administered group, HF-D: high-fat diet + lemon vinegar administered group, and HF-E: high-fat diet + balsamic vinegar administered group Hee-Kyoung Son et al.
