大多数超市面包都含有与肠道炎症有关的添加剂. 含有乳化剂和防腐剂的高度加工的面包可能会使炎症性肠道疾病 (IBD) 恶化. 建议IBD患者选择低加工面包.
科学领域:
- 胃肠病学和营养科学 胃肠病学和营养科学
- 食品科学和添加剂分析
- 微生物组研究 微生物组研究
背景情况:
- 超加工食品 (UPF) 的消费,特别是含有食品添加剂 (FA) 的面包,与炎症性肠病 (IBD) 风险增加有关.
- 工业面包生产经常包含乳化剂和防腐剂,引发了人们对其对肠道健康的影响的担忧.
- 了解面包中的特定FA及其生物学影响对于IBD管理至关重要.
研究的目的:
- 选面包产品的成分和FA,按加工水平分类它们.
- 审查科学文献关于已识别的FA对肠道微生物群和炎症的生物学影响.
- 评估商用面包中可能有害的FA的流行程度.
主要方法:
- 从以色列超市和健康食品商店检查了233种面包产品.
- 根据营养学家的成分分析,将面包分为低加工,中加工和高加工.
- 文献综述侧重于FA,肠道微生物群和肠道炎症之间的联系.
主要成果:
- 84%的选面包是高度加工的,含有防腐剂 (81%) 和乳化剂 (76%).
- propionate 和 stearoyl-2-lactylate 分别是最常用的防腐剂和乳化剂.
- 在现有文献中,超过50%的确定的FA与炎症恶化或肠道失调有关.
结论:
- 在以色列,大多数面包都经过过加工,含有可能促进肠道炎症的脂肪酸.
- 存在低加工面包选择,可能更适合IBD患者.
- 对FA在IBD病因学中的作用的进一步研究可以为临床饮食指南提供信息.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
