1

What are pathogens

Bad microorganisms

2

What is classed as good intestinal health?(2)

When we have 85% of good microbes
Less than 15% pathogens

3

Characteristics of an effective probiotic (7)

Non pathogenic
Species compatibility
GI attract survival
Good adherence
Short generation time
Production of anti microbial agent
Good survival in foods

4

Define probiotics (2)

Live microorganisms
That when administered in adequate amount will confer a health benefit to the host

5

Predominant types of bacteria colonising the GI tract (3)

Lactobacillus
Bifidobacterium
Streptococcus

5

The role of prebiotics

Favourably alter gut microflora in a similar way to probiotics

6

Ideal characteristics of prebiotics (3)

Ability to resist digestion
Be selectively fermented by the colon bacteria
Beneficially modulate gut bacteria

7

Suggested health benefits of pre/probiotics (6)

Cholesterol lowering
IBS
Childhood eczema
Colorectal cancer
Immunity
Diarrhoea treatment

8

Pre/probiotics mechanisms (7)

Modification of gut microflora
Stabilisation if indigenous microflora
Reduction in the duration of virus shredding
Reduction in increased gut permeability by viruses
Reduction in pathogenic bacteria - reduces inflammation
Lowering gut pH
Stimulates immune response

9

Criteria of health claims (3)

Characterisation of the strain or each strain
Identification of health relationship to benefit general population
Demonstration of health effects on normal healthy population

Probiotics may decrease the risk of which cancer?

Colorectal

16

What must scientific evidence demonstrate before a health claim can be made?(4)

Importance of the claimed health effect
Whether a scientific cause and effect had been established between consumption and health effect
Quantity of the product to obtain claimed effect
Target population and the evidence of the effect on that population
