| 摘要: |
| 肥胖是2型糖尿病、心血管病和多种癌症的危险因素，其防治形势十分严峻。Omega-3多不饱和脂肪酸（n-3 PUFA）是一种从深海鱼类中提取出来的多不饱和脂肪酸，具有显著的抗炎和降低三酰甘油的作用，但其抗肥胖作用仍有争议。在动物模型中发现，n-3 PUFA可以有效降低脂肪含量；然而人体研究却表明n-3 PUFA可能无助于减肥，但可能会减少体质量进一步增加。n-3 PUFA可通过调节肠道菌群、调节脂质代谢、抑制食欲、缓解脂肪组织炎症和表观遗传改变等机制改善与肥胖相关的代谢变化，从而在肥胖与其相关代谢性疾病的防治中发挥重要作用。 |

| Abstract: |
| Obesity is a risk factor for type 2 diabetes, cardiovascular diseases, and various cancers. The prevention and treatment of obesity have become the focus of public health. Omega-3 polyunsaturated fatty acids (n-3 PUFA) are polyunsaturated fatty acids extracted from deep-sea fish. The anti-inflammatory and triglyceride-lowering properties of n-3 PUFA are well known, but its role in the treatment of obesity is still controversial. In animal models, n-3 PUFA can effectively reduce fat. However, in humans, existing studies have shown that n-3 PUFA may not contribute to weight loss, but may slow down weight gain. N-3 PUFA can improve the metabolic changes associated with obesity by regulating intestinal flora, regulating lipid metabolism, suppressing appetite, alleviating adipose tissue inflammation and altering epigenetic mechanisms, thus playing an important role in the prevention and treatment of obesity and the related metabolic diseases. |
