短鏈脂肪酸(SCFA)近年來開始被認為是人體健康與否的指標之一，隨著腸道菌群檢測技術的日新月異，人們發現菌種的不同直接影響了一個人的一生，無論是肥胖、癌症、高血壓甚至對於心理疾病皆有所關聯，然而短鏈脂肪酸作為腸道中細菌的一級代謝物同樣的也與健康息息相關，根據研究指出在人體中短鏈脂肪酸的濃度比列可能會提高特殊疾病罹患的風險，並且短鏈脂肪酸隨著腸道的吸收，也會直接的影響人體的代謝機制，因此檢測短鏈脂肪酸成為與腸道菌群檢測共同判別的重要指標。

Short-chain fatty acids (SCFA) have begun to be considered as one of the indicators of human health in recent years. With the rapid advancement of gut flora detection technology, people have found that different strains of bacteria directly affect a person's life, whether it is Obesity, Cancer, High blood pressure and even Mental illness are all related. However, short-chain fatty acids, as primary metabolites of bacteria in the gut, are also closely related to health. According to research, the concentration ratio of short-chain fatty acids in the human body may increase the risk of special disease, the short-chain fatty acids will also directly affect the body's metabolic mechanism as they are absorbed in the intestines. Therefore, the detection of short-chain fatty acids has become an important indicator together with the detection of gut microbiota.
