脂肪酸和饮食在哮喘发病过程中炎症介质的形成中起着重要作用。由于摄入omega-6 (n-6)和omega-3 (n-3)脂肪酸的变化最终决定了细胞膜的掺入,饮食的改变有可能改变这些化合物衍生的炎症介质的下游生产。长期以来,人们一直假设,降低n-6/n-3比率可以减少更多促炎介质的产生,同时增加下游代谢物的形成,这些代谢物可以限制或缓解炎症。反过来,这些变化将导致哮喘结果的改善或降低哮喘发病率的风险。这篇综述将重点关注脂肪酸炎症和解决介质的作用,并将总结关于饮食和肥胖如何改变可能导致哮喘的脂肪酸谱的临床和流行病学数据。
Fatty acids and consequently diet play an essential role in the formation of inflammatory mediators involved in the pathogenesis of asthma. Because intake variations of omega-6 (n-6) and omega-3 (n-3) fatty acids ultimately determine cell membrane incorporation, changes in diet have the potential to modify downstream production of inflammatory mediators derived from these compounds. It has long been hypothesized that decreasing the n-6/n-3 ratio could reduce the production of more proinflammatory mediators while increasing the formation of downstream metabolites that can serve to limit or resolve inflammation. In turn, these changes would result in improved asthma outcomes or would lower the risk for asthma incidence. This review will focus on the role of fatty acid inflammatory and resolving mediators and will summarize the clinical and epidemiologic data on how diet and obesity alter fatty acid profiles that can contribute to asthma.
