Diet is an important factor influencing the pathogenesis of Crohn's disease (CD) and ulcerative colitis (UC). Several recent prospective cohorts have suggested various dietary factors may play a role in modifying the risk of these diseases. These include an inverse association between dietary fiber, fruit or vegetable intake and risk of CD and n-3 polyunsaturated fatty acids and UC. In addition to macro-nutrients, dietary additives such as emulsifiers may also play a role.
饮食是影响克罗恩病(CD)和溃疡性结肠炎(UC)发病机制的重要因素。最近的几项前瞻性队列研究表明,各种饮食因素可能在改变这些疾病的风险中发挥作用。这些因素包括膳食纤维、水果或蔬菜摄入量与CD风险之间的负相关,以及n-3多不饱和脂肪酸与UC之间的负相关。除了宏量营养素外,乳化剂等食品添加剂也可能起作用。
