Prebiotics and probiotics

Question 1

Probiotics

Answer 1

live micro-organisms that when administered in adequate amounts provide a health benefit to the host.

• colonise the gut - crowd out pathogenic bacteria
• supress the growth of pathogenic bacteria - block epithelial attachment or invasion by pathogens. (out compete pathogenic bacteria for nutrients)
• enhance mucosal functions (cell lining GIT)
• improve the ability for immune cells to destroy pathogens
