Soy's Role in Estrogen Production

Speaker 1
0:59

Let's

dive

in
.

What

role

does

soy

play

in

estrogen
?

Speaker 2
1:16

production

for

endometriosis

patients
?

Is

it

harmful

to

have

soy

or

is

that

kind

of

a

myth

estrogen

production
?

So

the

phytoestrogens

which

are

in

soy

products

generally

are

helpful
.

What

I

usually

counsel

patients

on

and

I

don't

really

see

in

our

American

diet
.

I

have

very

few

patients

who

are

eating

soy

regularly

in

general
,

not

because

they're

avoiding

it
,

but

we

don't

tend

to

drink

soy

milk
.

We

don't

tend

to

eat

a

lot

of

tofu

or

edamame
.

Having

it

a

couple

of

times

a

week

should

be

completely

safe

for

endometriosis
.

For

some

people

it

does

cause

bloating

and

symptoms

and

if

that's

you
,

then

don't

eat

it
.

But

tofu

is

a

really

great

source

of

calcium

and

healthy

lean

protein
,

which

a

lot

of

people

with

endometriosis

also

have

high

cholesterol

Research Studies on Soy and Endometriosis

Speaker 2
2:02

and

things

like

that
.

So

I

would

say

okay

for

soy
.

Speaker 2
2:05

There

was

a

study

done

by

Mumford

that

found

no

significant

difference

in

phytoestrogen

levels

between

women

with

and

without

endometriosis
.

So

that

suggested

that

phytoestrogen

intake

does

not

play

a

clear

role

in

preventing

or

progressing

endometriosis
.

There

was

another

study

done

by

I'm

going

to

butcher

it
,

but

Yusuflu
,

who

found

that

higher

intake

of

levels

of

isoflavones
,

lignans

and

phytoestrogens

correlated

with

endometriosis

risk
,

so

inversely
.

So

the

more

soy

that

they

consumed
,

the

less

endometriosis

that

there

were
.

So

there

was

less

risk

of

developing

endometriosis

with

soy

consumption
.

And

then

there

was

another

study

that

showed

that

the

urine

levels

of

soy

products

were

inversely

associated

with

it

as

well
.

Speaker 2
2:52

So

I

would

say

yes
,

soy

should

be

safe

for

endometriosis
.

One

of

the

things

we

might

want

to

look

at

is

using

like

non-GMO

soy

or

organic

and

kind

of

paying

attention

to

the

sources

of

soy
,

and

again
,

most

people

in

real

life

are

not

eating

like

two

or

three

serving
,

kind

of

paying

attention

to

the

sources

of

soy
,

and

again
,

most

people

in

real

life

are

not

eating

like

two

or

three

servings

of

soy

every

single

day

Individual Responses to Soy Consumption

Speaker 2
3:10

.

So

anything

we

eat

too

much

of

we

should
,

you

know

question
.

We

also

don't

want

to

eat

like

seven

servings

of

broccoli

every

single

day
.

Anything

too

much

is

going

to

make

you

feel

unwell
,

right
?

Speaker 1
3:22

I

mean
,

I

ran

into

that

fear

of

like

the

soy

for

a

really

long

time

and

it

doesn't

make

me

feel

great

so

I

don't

eat

it
.

But

I

think

there

are

a

lot

of

people

that

do

well

with

it

and

don't

have

adverse

reactions

to

it

and

you

know

have

had

excision

and

they

don't
,

and

they

eat

soy

after

and

they're

fine
.

Speaker 2
3:40

There's

a

lot

of

people

in

the

population
,

the

endometriosis

population
,

that

are

sensitive

to

gluten
.

So

like

soy

sauce

contains

gluten
,

but

the

soy

may

not

be

the

issue
.

And

then

I

have

some

patients

that

soy

really

bloats

them

and

makes

them

feel

unwell

or
,

you

know
,

might

cause

diarrhea
.

So

it's

just

so

hard

because

there's

so

many

people

who

have

endometriosis

and

every

body

is

going

to

react

differently

to

that

thing

and

it

may

not

actually

be

because

of

endo
,

but

just

your

genetic

history
.

What's

going

on

with

your

microbiome
,

things

like

that
.

So
,

as

with

anything
,

it's

individualized
,

but

soy

should

be

safe
.
