Exploring Gut Microbiome Modulation for Disease Prevention

Carriers of gut Blastocystis, a single-celled organism that has been classified as either a parasite or harmless organism but is frequently found in the digestive system, were associated with markers of good cardiovascular health and decreased body fat in an analysis of over 50,000 people from around the world.

Investigating the Link Between Metabolism and Intestinal Development

Intestines can reach a length of 15 feet or more; how does it fit within human bodies properly? The gut tube dramatically loops and rotates to bundle the extending intestine as the digestive system grows. Intestinal malrotation is a common, but poorly understood, birth defect caused by the failure of the gut to rotate correctly during development.

Tomatoes as Nature's Antibacterial Agents

According to research published in Microbiology Spectrum, a magazine of the American Society for Microbiology, tomato juice can eliminate Salmonella Typhi and other bacteria that can damage people's digestive and urinary system health. Typhoid fever is brought on by the lethal human-specific bacterium Salmonella Typhi.
