Sea tangle (Laminaria japonica) is well known as having anti-diabetic and hypolipidemic effects in animals as well as in humans. In this study, we evaluated the effects of sea tangle-added patty on postprandial blood glucose and lipid profiles in borderline-hypercholesterolemic (cholesterol ≥200 mg/dL) adults. Eleven subjects voluntarily participated in the experiment, and each subject provided written consent. Experimental patty (E) was made by adding 2.25 g of sea tangle powder as a substitution to 1.125 g each of pork and chicken. In the first week, 200 g of Control patty (C) was provided to each subject, who had fasted more than 12 hours. In the second week, the same amount of E patty was supplied under the same conditions. Serum glucose levels increased significantly less at 30, 60, and 120 min after consumption of E patty compared to the levels at all time points after eating C patty. Thus, the change in the area under curve (ΔAUC) of serum glucose levels through 120 minutes was lower when consuming E patty compared to C patty. Although serum C-peptide concentrations were not significantly different at all time points between the two patties, the ΔAUC of serum C-peptide concentrations through 120 minutes was lower when consuming E patty compared to C patty. However, there were no differences in serum levels of triglyceride, total cholesterol, LDL-C, and HDL-C at 30, 60, 120, 180, and 240 min between the two patties. Further, each ΔAUC of these lipid levels through 240 minutes was not significantly different between the two patties. The results indicate that sea tangle-added patty may decrease postprandial plasma glucose concentrations and reduce insulin secretion, although it might not ameliorate serum lipid profiles in adults with borderline-hypercholesterolemia.
