Abstract: |
Oils and fats are one of the three main nutrients in the human body. A balanced diet of oils and fats provide energy to the body, enhance immune function, and maintain neurological and physiological activities. Triacylglycerol (TAG), the main component of edible oils and fats, is easily converted into stored fat after digestion and metabolism, which can burden the body. Diacylglycerol (DAG) is a natural substitute for TAG in edible oil and has been proven to have various nutritional functions. To provide a theoretical basis for the application of DAG as a new type of healthy fat, the metabolic mechanism and main nutritional functions of DAG were reviewed. DAG has similar physicochemical properties to TAG, but due to differences in metabolic pathways and the ability to regulate the expression of genes related to oil oxidation, DAG has multiple functions such as promoting fat oxidation, inhibiting body weight gain, reducing visceral fat content, improving serum cholesterol, regulating blood sugar, and lowering blood lipids. The intake of DAG can effectively reduce the risk of metabolic syndrome and cardiovascular disease. |
