A fascinating examination of the three pounds of bacteria living in a typical human being.

We are a society obsessed with cleanliness -- but is this a healthy obsession? Do we use antibacterial products correctly? Should my child wash her hands after playing in the park? Why does my doctor insist that I finish the bottle of antibiotics even though I feel better? What is Lactobacillus? And superbugs?

The human body plays host to trillions of bugs -- living microorganisms too tiny to see -- including our own personal, unique set of bacteria. We're only just beginning to understand the important role these bacteria play in human health.

This highly topical and accessible book covers bacteria from all angles and includes:

• The different bacteria that live on and in various parts of your body (not just in the gut)
• What these bacteria do, and why some are beneficial and some harmful
• Practical advice for promoting the good and inhibiting the bad bacteria
• The latest thinking on "clean" environments and the links between bacteria and disease
• Bacteria in pregnancy and birth and how children's bacteria set them up for life
• The causes of an unhealthy gut, including travel, eating a different diet, prolonged stress, intestinal parasites and improper use or overuse of antibiotics
• The current research, including fecal transplantation from a healthy person's gut flora to that of an unhealthy gut
• The difference between prebiotics and probiotics and their health benefits, and much more.

Advertisers insist that bacteria are bad. Are they? Meet Your Bacteria has the answers.
