4. Individual diet has little effect on the diversity of an individual's gut microbiome.

Question 4 of 10

5. Probiotics are foods or dietary supplements that contain live microorganisms that, when administered in adequate amounts, have been shown to provide a health benefit for the individual who consumes them. If the microorganisms are not alive, they are not true probiotics.

Question 5 of 10

6. Although there are many probiotic foods and supplements on the market, research evidence to date about health benefits in humans is inconclusive, though promising.

Question 6 of 10

7. Research shows that the content of an individual's diet does not affect the amount and diversity of microbes in the GI tract.

Question 7 of 10

8. To date, research in animals has suggested a relatively strong relationship between the individual gut microbiome and obesity; however, research on such a potential link in humans remains inconclusive.

Question 8 of 10

9. The composition and variety of an individual's gut microbiome has not yet been shown to be one factor in an individual's post-meal blood glucose response.

Question 9 of 10

10. Overall, the webinar presented research that indicates that the gut microbiome is integral to human physiology and plays a role in the maintenance of health and development of disease.
