JANEANE DART: Foods have
been used historically,

00:00:13.380 --> 00:00:16.740 align:middle line:84%
across cultures and for
centuries in treating

00:00:16.740 --> 00:00:18.970 align:middle line:90%
disease and curing illness.

00:00:18.970 --> 00:00:21.710 align:middle line:84%
Over the past 20 years,
the evidence has built

00:00:21.710 --> 00:00:25.350 align:middle line:84%
and we're able to draw on that
now in making recommendations

00:00:25.350 --> 00:00:28.260 align:middle line:84%
for the public, and certainly
in specific diseases

00:00:28.260 --> 00:00:29.280 align:middle line:90%
and conditions.

00:00:29.280 --> 00:00:31.720 align:middle line:84%
For example, in
the past 20 years,

00:00:31.720 --> 00:00:35.770 align:middle line:84%
irritable bowel is a syndrome
which has grown in prevalence.

00:00:35.770 --> 00:00:38.210 align:middle line:84%
20 years ago, we were
recommending wheat bran

00:00:38.210 --> 00:00:40.830 align:middle line:84%
as a strategy for
people to try and help

00:00:40.830 --> 00:00:42.680 align:middle line:90%
manage their irritable bowel.

00:00:42.680 --> 00:00:44.170 align:middle line:84%
And what we know,
from studies that

00:00:44.170 --> 00:00:46.760 align:middle line:84%
have occurred subsequently,
is that made things worse

00:00:46.760 --> 00:00:48.710 align:middle line:90%
for about 50% of patients.

00:00:48.710 --> 00:00:51.540 align:middle line:84%
What we know now, and what
I've used in clinical practice,

00:00:51.540 --> 00:00:52.820 align:middle line:90%
is linseed.

00:00:52.820 --> 00:00:54.900 align:middle line:90%
So golden or cracked linseed.

00:00:54.900 --> 00:00:59.610 align:middle line:84%
It can be added into water,
sprinkled on yogurt, in salads.

00:00:59.610 --> 00:01:01.990 align:middle line:90%
So, really easy to consume.

00:01:01.990 --> 00:01:04.319 align:middle line:84%
Anywhere between about
a tablespoon to two

00:01:04.319 --> 00:01:07.240 align:middle line:84%
or three tablespoons a day
can have significant benefit

00:01:07.240 --> 00:01:08.960 align:middle line:90%
improving their symptoms.

00:01:08.960 --> 00:01:11.900 align:middle line:84%
And there is a modest
evidence in supporting people

00:01:11.900 --> 00:01:14.550 align:middle line:84%
with constipation
predominant irritable bowel.

00:01:14.550 --> 00:01:16.986 align:middle line:84%
In addition, it's also
really high in omega-3.

00:01:16.986 --> 00:01:18.610 align:middle line:84%
So it's a really good
vegetable source,

00:01:18.610 --> 00:01:21.290 align:middle line:90%
or plant source of omega-3.

00:01:21.290 --> 00:01:25.910 align:middle line:84%
Another strategy, or using
food to treat an illness,

00:01:25.910 --> 00:01:28.220 align:middle line:84%
this is a sample
here of some foods

00:01:28.220 --> 00:01:30.980 align:middle line:84%
that are high in
fermentable carbohydrates.

00:01:30.980 --> 00:01:32.710 align:middle line:90%
Or they high FODMAP foods.

00:01:32.710 --> 00:01:34.680 align:middle line:84%
That's the term
that's being used.

00:01:34.680 --> 00:01:37.290 align:middle line:84%
And so we know from evidence
of the past 15 years

00:01:37.290 --> 00:01:39.780 align:middle line:84%
or so, that reducing
someone's intake

00:01:39.780 --> 00:01:42.350 align:middle line:84%
of fermentable
carbohydrate can offer them

00:01:42.350 --> 00:01:44.550 align:middle line:84%
really significant
benefits to their symptoms

00:01:44.550 --> 00:01:45.980 align:middle line:90%
of irritable bowel.

00:01:45.980 --> 00:01:48.300 align:middle line:84%
While they're very
healthy foods generally,

00:01:48.300 --> 00:01:50.620 align:middle line:84%
for people with irritable
bowel they can potentially

00:01:50.620 --> 00:01:52.810 align:middle line:90%
cause symptomatic problems.

00:01:52.810 --> 00:01:55.760 align:middle line:84%
So, for about 3/4 of people
with irritable bowel,

00:01:55.760 --> 00:01:59.150 align:middle line:84%
having a diet that removes
these foods, temporarily

00:01:59.150 --> 00:02:02.510 align:middle line:84%
from their diet, can
actually reduce symptoms.

00:02:02.510 --> 00:02:06.170 align:middle line:84%
And then people with IBS
can work with a dietitian

00:02:06.170 --> 00:02:09.639 align:middle line:84%
to tailor how much tolerance,
or how much of these things

00:02:09.639 --> 00:02:12.310 align:middle line:84%
they can re-include
back into their diet.

00:02:12.310 --> 00:02:13.880 align:middle line:84%
So that's a really
significant thing,

00:02:13.880 --> 00:02:16.690 align:middle line:84%
where food can be used as
treaty in the management

00:02:16.690 --> 00:02:20.680 align:middle line:84%
of irritable bowel, which is
a syndrome which can really

00:02:20.680 --> 00:02:24.270 align:middle line:84%
have profound and debilitating
reductions in quality of life

00:02:24.270 --> 00:02:25.950 align:middle line:90%
for people who suffer from it.

00:02:25.950 --> 00:02:28.520 align:middle line:84%
Here are some oats, and a
range of different legumes,

00:02:28.520 --> 00:02:30.680 align:middle line:84%
so some lentils
and some chickpeas.

00:02:30.680 --> 00:02:33.380 align:middle line:84%
While they're not new,
there's nothing fancy,

00:02:33.380 --> 00:02:36.340 align:middle line:84%
including these foods
regularly into your diet

00:02:36.340 --> 00:02:39.510 align:middle line:84%
can have, again, significant
impacts in reducing blood sugar

00:02:39.510 --> 00:02:41.810 align:middle line:84%
levels, for people
with diabetes.

00:02:41.810 --> 00:02:45.286 align:middle line:84%
Because they're rich in fiber--
in particular, soluble fiber--

00:02:45.286 --> 00:02:46.660 align:middle line:84%
they also have a
really good role

00:02:46.660 --> 00:02:50.110 align:middle line:84%
to play in appetite regulation
and supporting weight

00:02:50.110 --> 00:02:50.970 align:middle line:90%
management.

00:02:50.970 --> 00:02:53.110 align:middle line:84%
And of course, a healthy
weight can actually

00:02:53.110 --> 00:02:56.160 align:middle line:84%
be a very important management
strategy in diseases

00:02:56.160 --> 00:02:57.450 align:middle line:90%
such as diabetes,

00:02:57.450 --> 00:02:59.540 align:middle line:84%
More recent research,
interestingly,

00:02:59.540 --> 00:03:00.800 align:middle line:90%
is looking at ginger.

00:03:00.800 --> 00:03:04.280 align:middle line:84%
And ginger is a root that's
been around for years.

00:03:04.280 --> 00:03:06.520 align:middle line:84%
It's been used in Indian
and Chinese medicine

00:03:06.520 --> 00:03:08.320 align:middle line:84%
for thousands of
years, and certainly

00:03:08.320 --> 00:03:10.010 align:middle line:90%
in other Asian cultures.

00:03:10.010 --> 00:03:10.680 align:middle line:90%
It's a root.

00:03:10.680 --> 00:03:13.680 align:middle line:84%
We can grate it into
curries, into stir fries,

00:03:13.680 --> 00:03:15.380 align:middle line:90%
we can use it in tea.

00:03:15.380 --> 00:03:20.050 align:middle line:84%
But ginger is being studied for
it's anti-nausea properties.

00:03:20.050 --> 00:03:22.260 align:middle line:84%
So it's been used in
pregnancy and travel sickness

00:03:22.260 --> 00:03:24.190 align:middle line:84%
for a long time,
but it's now being

00:03:24.190 --> 00:03:27.390 align:middle line:84%
researched in the context
of chemotherapy and cancer

00:03:27.390 --> 00:03:28.180 align:middle line:90%
treatment.

00:03:28.180 --> 00:03:29.650 align:middle line:84%
And there's some
promising evidence

00:03:29.650 --> 00:03:31.770 align:middle line:84%
that ginger can
have a role to play

00:03:31.770 --> 00:03:34.820 align:middle line:84%
to support chemotherapy
treatment and cancer

00:03:34.820 --> 00:03:35.610 align:middle line:90%
management.

00:03:35.610 --> 00:03:38.430 align:middle line:90%
Turmeric also is a rhizome.

00:03:38.430 --> 00:03:39.760 align:middle line:90%
It looks like ginger.

00:03:39.760 --> 00:03:42.260 align:middle line:84%
And it's been used in
Indian and Chinese medicine

00:03:42.260 --> 00:03:43.820 align:middle line:90%
for thousands of years.

00:03:43.820 --> 00:03:46.090 align:middle line:84%
In the West, we're just
beginning to use it more

00:03:46.090 --> 00:03:47.370 align:middle line:90%
and learn more about it.

00:03:47.370 --> 00:03:51.010 align:middle line:84%
And it's actually been
isolated into a supplement

00:03:51.010 --> 00:03:54.020 align:middle line:84%
because the active compound
in turmeric is curcumin.

00:03:54.020 --> 00:03:56.730 align:middle line:84%
It's an antioxidant and
it's really just beginning

00:03:56.730 --> 00:03:59.420 align:middle line:84%
to show some
benefits, potentially

00:03:59.420 --> 00:04:01.635 align:middle line:84%
in terms of
anti-inflammation, so

00:04:01.635 --> 00:04:04.530 align:middle line:84%
in managing something such
as rheumatoid arthritis,

00:04:04.530 --> 00:04:07.350 align:middle line:84%
and also my have a role to
play in cancer management.

00:04:07.350 --> 00:04:09.630 align:middle line:84%
So this is an interesting,
quite a small,

00:04:09.630 --> 00:04:11.190 align:middle line:84%
but an interesting
selection of how

00:04:11.190 --> 00:04:14.336 align:middle line:84%
food can be used in treating
illness and disease.

00:04:14.336 --> 00:04:15.710 align:middle line:84%
And you will have
an opportunity,

00:04:15.710 --> 00:04:18.240 align:middle line:84%
through the course, to do
some of your own exploration

00:04:18.240 --> 00:04:20.660 align:middle line:90%
and research around this.

00:04:20.660 --> 00:04:26.070 align:middle line:90%
