My name is Eliza Kingsford I am a licensed psychotherapist specializing
in body image and eating disorders and obesity
and I am the Executive Director of Wellspring. Hi my name is Nicole Avena
I am a PhD neuroscientist and
author and expert in the fields of diet, nutrition and addiction.
I am an assistant professor of pharmacology at the Ichan School of Medicine
at Mount Sinai
in New York City and I also do work with Wellspring Camps in a
consulting role.
So according to you a recent survey conducted we found that 92% of
Americans believe that food can be an addictive substance
and even further more 66% percent of them said
that it could possibly take up to two weeks to recover
from a sugar or food addiction
and feel better from that so given those findings and what we know about addiction
we know that to recover from an addiction that
incredible support and commitment and consistency is necessary
oftentimes behavioral therapy and intervention is necessary and sometimes
medical intervention
is necessary. It is remiss to say
that folks suffering from a food addiction could be
cured or helped or relieved by just
asking them to eat less and move more and
just go to the gym and and eat fewer calories. We know that this is a complex
issue and a complex problem that is
incredibly more complicated than that.
Certainly food addiction is a concept that the scientific community has been
studying for many years now
and this is something that we've seen scientific evidence for not only in
terms of
evidence of addiction like behaviors that can emerge in response to eating
highly palatable foods but also more importantly
there's significant evidence that there's changes in the brain
that are associated with chronic overeating that resemble what you
would see
during an addiction like state, so there's certainly a significant amount
of research
that is being conducted and continues to be going
on that is looking at this area of food addiction
and I think we're at the point now where we're at beginning to be able to ask
questions about
what does this mean for treatment and it certainly does mean that we need to
revamp
and reconsider some of the approaches that we traditionally use to treat
overeating and obesity
It may work for some people but it may not work for others and so
adopting an
addiction model and considering that with respect to treatment really opens
the door
and can give the potential to help many different people who are suffering
from overeating.
So a lot experiments have been conducted
both in our laboratory and also in other laboratories throughout the country that
have been asking the question of how can foods act like drugs of abuse in
terms of what happens in the brain
and so one of the things that we've learned is that when
we consume food it's reinforcing and it feels good.
And as a result that releases a neurochemical in the brain called
dopamine. Now typically when we eat a food for the very first time
that dopamine release occurs but it has more to do with the novelty of the
food
and so we want to be careful to remember that very first time we eat
new food
we need to pay attention so that dopamine signal loss to pay attention
so once we've consumed a food a few different times we know that it's
safe
doughnuts release dopamine in response to eating it because
we don't have to necessarily worry about that food causing us to be sick or to
get
ill from consuming it anymore there's no more
of a threat really in terms of survival and so the dopamine release
tends to attenuate or lessen with repeated exposures
Now on the other hand, drugs of abuse release dopamine every time they're
administered so every time someone administers nicotine, cocaine, morphine
pretty much any drug releases dopamine that's one of the hallmarks of drug
use
What's interesting though is that science has shown us that
when laboratory animals over consume sugar
it acts more like what you see with a drug
that every time the animals were eating sugar it's releasing dopamine
and so in many ways this pattern of release looks more like what you'd
expect to see with a drug and less like what you would expect
typically see with a food. There's been lots of clinical studies that have
gone on to
expand on this area of research showing changes in the brain that are
consistent with
alterations in addiction areas is in humans as well
and so it seems that the dopamine systems are perturbed
by overconsumption of sugar and highly palatable foods.
And its preservation occurs in a way that is similar to what you'd see with
an addiction to drugs.
So from our survey results we found that 40%
of adults ages 18 to 34
did not feel like their parents set
a good example or or gave them good guidelines for being healthy with
food consumption. We thought that was really interesting and
wondered if
the emerging science specific to that age group 18-34
that is something has changed to
perhaps prevent people from being able to provide guidelines or is it
the guidelines or
example I should say
has changed over the years in what parents are doing with food.
Yeah I think that particular age range
falls within the range I'm just outside at that age range so I feel like I can
relate to the participants in many ways
in that the guidelines that were provided
to adults in terms of healthy eating and what we should be feeding our children
really haven't been very good. We're only now
recently seeing serious discussion in my opinion about changing the food intake
guidelines about making changes to
you know how much recommended sugar is consumed each day
and we're also seeing you know some discussion and debate about changes in
nutrition labels, making nutrition information
nutrition facts label more apparent and more obvious so that people can
understand it better.
So I I think that you know by no fault of the parents of those
individuals between the ages 18 and 34 I
do believe that there just hasn't been a lot of good information provided
for parents to educate children about healthy eating practices.
I also think that you know we live in a culture now in which
mom and dad often both work there's many opportunities
you know for us to just simply grab something quick
or eating out and so cooking at home and taking the time to prepare
meals at home often falls to the wayside
and I think that the sort of long-term ramifications of that
haven't necessarily been taken very seriously until recently where we're now
seeing
issues related to obesity and more importantly I think it's issues related
to behavior change
and so when children are exposed to
certain types of eating practices that they
receive from their family life at home it's hard to break those habits later in
life.
So if you grow up drinking soda and having dessert every single night, it
becomes a way of life
that becomes the norm and so it's difficult to make those changes once you
become an adult. You start to have medical problems that are
potentially related to those behaviors. Right.
I think now we're starting to see a bit of a change in tide in that
you know we're starting to see recommendations being made by the World
Health Organization for instance to
change the recommended amount of sugar intake that children should be having
and it's a drastic reduction. It's much less than what
is currently being consumed much less
of what's presently available so I think that
over time we should see some additional changes and hopefully with the next
generation
they won't necessarily feel the way that this particular one does.
I want to take the time to thank Dr. Avena for her time today and the incredible
work
that you do in the research field and research realm
that really changes and guides a lot of the treatment that is out there.
Without researchers like you, we
we wouldn't be able to advance and to tailor the treatment in the way
that we need to. Without the research
in the findings in the science we wouldn't be able to provide
the effective treatment outcomes that that we're able to provide
based on based on that research and based on your findings and I just
wanted to thank you for hanging out with me today and for anyone who's
watching or listening I hope this provides more information about the
the problems that we're facing with food and the struggles that people
can have with food
and why they might be struggling and let you know that
Wellspring is a program that's out there to help and to provide the treatment
necessary
to get you on your way to a healthier lifestyle.
As a final thought I would say that there is evidence that
food addiction is real and this is something that can be affecting
adults and children and young adults as well
and I think that it's important for people to realize that
by taking an addiction approach to the addiction
process in terms of the treatment there is
evidence that it can be effective and people who have struggled with obesity
and overeating for many years
may find that looking at their problem through an addiction lens
can be the way to finally achieve whatever their goals are for healthy eating
and this isn't necessarily something that can be done alone and I think we know
from
looking at the history of addiction to other substances like drugs and alcohol
it's not easy it's not something that people often can do by themselves and so
finding the right resources and the right groups that can assist you
with your goals is the way to go.
