Abstract

Metabolic syndrome is known as an important risk factor for cardiovascular disease. Hyperlipidemia and visceral fat accumulation could be caused by excessive fat intake. Soybeans contain several components, such as phytosterols (PS), that lower the levels of serum triglycerides (TG) and cholesterol (Cho) and prevent obesity. In addition, soybean paste (miso) is also known to have inhibitory effects on lipid absorption in animals. In this study, the synergistic effects of PS and miso on mouse plasma lipid levels were investigated. Administration of a high-fat diet or lipids increased the levels of TG and total cholesterol (TC) in mouse plasma. The concurrent ingestion of PS and miso significantly prevented the increase of these lipids in mouse plasma. The usage of PS and miso would be expected to suppress lifestyle-related diseases, such as atherosclerosis.

Key words: Plasma cholesterol, Phytosterols, Miso, Mouse
