thank you everyone for being here today

thank you everyone for being here today good afternoon our early days in life in

good afternoon our early days in life in

good afternoon our early days in life in many ways they set the tone for the

many ways they set the tone for the

many ways they set the tone for the quality of life later on and even though

quality of life later on and even though

quality of life later on and even though we have known this for four years now

we have known this for four years now

we have known this for four years now what if I told you today that the health

what if I told you today that the health

what if I told you today that the health of our baby’s guts and specifically the

of our baby’s guts and specifically the

of our baby’s guts and specifically the microbes that live within their guts can

microbes that live within their guts can

microbes that live within their guts can help us predict their future health see

help us predict their future health see

help us predict their future health see this idea of microbes promoting health

this idea of microbes promoting health

this idea of microbes promoting health is quite new and the reason is that for

another bacterial cell just in your guts

another bacterial cell just in your guts and for every gene in your cells there’s

and for every gene in your cells there’s

and for every gene in your cells there’s 10 to 15 bacterial genes in and with you

10 to 15 bacterial genes in and with you

10 to 15 bacterial genes in and with you at all times and this we didn’t know

at all times and this we didn’t know

at all times and this we didn’t know about that much about this until very

and again we didn’t know that much about

and again we didn’t know that much about this until very recently and how did we

this until very recently and how did we

this until very recently and how did we figure that out well through research

figure that out well through research

figure that out well through research but not just any research we started

but not just any research we started

but not just any research we started working on this using germ-free mice

working on this using germ-free mice

working on this using germ-free mice germ-free mice are animals that are born

germ-free mice are animals that are born

germ-free mice are animals that are born and raised in sterile conditions and

and raised in sterile conditions and

and raised in sterile conditions and laboratories they’re completely devoid

laboratories they’re completely devoid

laboratories they’re completely devoid of microbes and using these mice and

of microbes and using these mice and

of microbes and using these mice and comparing them with regular mice that

comparing them with regular mice that

comparing them with regular mice that Harbor microbes in them we found three

Harbor microbes in them we found three

Harbor microbes in them we found three essential ways that microbes keep us

essential ways that microbes keep us

essential ways that microbes keep us healthy the first one microbes out there

healthy the first one microbes out there

healthy the first one microbes out there are energy metabolism if you take a

are energy metabolism if you take a germ-free Mouse and if you put bacteria

germ-free Mouse and if you put bacteria

germ-free Mouse and if you put bacteria on it again this germ-free Mouse is

on it again this germ-free Mouse is

on it again this germ-free Mouse is going to experience a gain in weight of

going to experience a gain in weight of

going to experience a gain in weight of about 60% without eating more bacteria

about 60% without eating more bacteria

about 60% without eating more bacteria we know they break down food for us and

we know they break down food for us and

we know they break down food for us and they also allow us to extract more

they also allow us to extract more

they also allow us to extract more energy from it they also produce

energy from it they also produce

energy from it they also produce compounds that help dictate how you

compounds that help dictate how you store and burn energy we also know that

store and burn energy we also know that

store and burn energy we also know that there are key components of our immune

there are key components of our immune

there are key components of our immune system bacteria allow our immune system

system bacteria allow our immune system

system bacteria allow our immune system to mature and developed germ-free mice

to mature and developed germ-free mice

to mature and developed germ-free mice have very sloppy immune systems they can

have very sloppy immune systems they can

have very sloppy immune systems they can now control the seeds very well bacteria

now control the seeds very well bacteria

now control the seeds very well bacteria do that for us from the moment that were

do that for us from the moment that were
