Nutrition and intestinal bacteria

Intestinal Flora and Nutrition

Sir,?There is one aspect of study in nutrition which does not yet appear to have been accorded its true value. I refer to the part played by the organisms living inside the alimentary tract of man. To the majority studies on nutrition end at the stage at which the food is Swallowed. Others, more exact, define conditions in which absorption of the ultimate products of digestion is disturbed as f...

Intestinal bacteria and ageing.

Advancements in science and medicine, as well as improved living standards, have led to a steady increase in life expectancy, and subsequently a rise in the elderly population. The intestinal microbiota is important for maintenance of host health, providing energy, nutrients and protection against invading organisms. Although the colonic microbiota is relatively stable throughout adult life, ag...

Parenteral Nutrition and Intestinal Failure

Severe short bowel syndrome (SBS) is a major cause of chronic (Type 3) intestinal failure (IF) where structural and functional changes contribute to malabsorption and risk of micronutrient deficiencies. Chronic IF may be reversible, depending on anatomy and intestinal adaptation, but most patients require long-term nutritional support, generally in the form of parenteral nutrition (PN). SBS man...

Intestinal bacteria and ulcerative colitis.

Convincing evidence from both animal models and the study of patients with ulcerative colitis (UC) implicates the intestinal microflora in the initiation and maintenance of the inflammatory processes in this condition. Despite this, no specific pathogen has been identified as causal and the disease is widely believed to occur as the result of a genetically determined, but abnormal immune respon...
