概括
经常食用乳酸发酵蔬菜 (LFV) 极少影响肠道微生物组合,但显著增强便代谢组的多样性和有益的短链脂肪酸,如丁酸盐.
科学领域:
- 微生物学 微生物学
- 营养科学 营养科学
- 代谢学 代谢学 代谢学
背景情况:
- 工业化的西方饮食减少了乳酸发酵蔬菜 (LFV) 的摄入量.
- 消费LFV可能通过肠道微生物组调节提供健康益处,但机制尚不清楚.
研究的目的:
- 调查定期食用LFV对肠道微生物组成,多样性和便代谢组的影响.
- 为了比较LFV消费者和非消费者之间的饮食习惯.
主要方法:
- 使用16S rRNA和ITS2 amplicon测序分析微生物组成的便样本.
- 对便样本应用的非向LC-MS代谢量.
- 从参与者那里收集了三天的饮食记录.
主要成果:
- 在LFV消费者中观察到特定细菌 (例如,Leuconostoc mesenteroides) 的轻微丰富.
- 在LFV消费者中,便短链脂肪酸 (丁酸盐,酸盐,酸盐) 的显著增加.
- 在常规LFV消费者中,便代谢组的多样性大大增加 (P < 0.001).
结论:
- 消费LFV对肠道微生物组合的影响有限,但对便代谢产生明显影响.
- 需要进一步的研究来阐明LFV在人类饮食中的健康意义.

Bacterial Flora of the Large Intestine
397
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines
71.6K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

What is Monogastric Digestion?
70.9K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
