Why is it so hard to follow the FODMAP
diet, especially when there is so
2
:much information available online?
3
:Actually, the more information there
is, it can make it more confusing.
4
:The low FODMAP diet was developed
to help people with IBS.
5
:And most research shows it helps
about three out of four people
6
:better manage digestive symptoms.
7
:But it is not an intuitive diet to follow
on your own and it can be very confusing.
8
:So this is what I'm going
to be talking about in this
9
:episode of The Inside Knowledge.
10
:You'll learn what are FODMAPs,
when to try this diet and
11
:when not to, and how to start.
12
:And you'll also find out some of my
top tips on making the guidelines
13
:as easy as possible to follow.
14
:And welcome to episode 17 of the
Inside Knowledge for People with
15
:I B S, with me, Anna Mapson.
16
:Today we are going to dive into
the low FODMAP diet for I B Ss.
17
:I want to explain to you what it
is, how to do it, and whether it
18
:could be a good option for you.
19
:It's been developed specifically
for people with I B s and around
20
:75 percent of people will see
some kind of benefit from it.
21
:Now, if you have never heard of the low
FODMAP diet, it's basically an acronym.
22
:It stands for Fermentable
Oligosaccharides, Disaccharides,
23
:Monosaccharides and polyols.
24
:Those are the various letters and they
are each different types of starch.
25
:They're basically short chain
carbohydrates which are found in food.
26
:They can't be well digested
by humans and they're often
27
:broken down by our gut bacteria.
28
:This is a good thing.
29
:We want to feed our good beneficial
bacteria, but for some people with IBS
30
:these particular carbohydrates can draw
water into the bowel which creates loose
31
:stools or Because of the fermentation
process it can create excessive gas.
32
:So if you've never thought about what
these foods might actually involve Let us
33
:just go through a list of them and see.
34
:So oligosaccharides, this includes
two key subsections, really.
35
:There's galacto oligosaccharides,
which is often found in nuts and
36
:seeds, beans and lentils, almonds,
chickpeas, those are all high goss foods.
37
:And then also in that first
oligosaccharides, we've got, uh, fructans.
38
:And these are long chains of fructose
modules that are linked together.
39
:This is found in foods like wheat,
onions, garlic, grapefruit, courgette.
40
:If you haven't listened to my episode
about gluten and fructans, I did mention
41
:a bit about that last week, episode 16.
42
:So you go back and listen to a summary
of fructans but just as an example,
43
:those are some of the foods included
in the oligosaccharide category.
44
:Then we've got the D, the
disaccharides, that's lactose,
45
:which is found in dairy foods.
46
:The monosaccharides, that's a single
saccharide, and the disaccharide,
47
:obviously two saccharides stuck together.
48
:Um, but this includes fructose in,
so monosaccharides category includes
49
:fructose, which is in tomatoes, mango.
50
:red pepper, grapes, and
some stone fruits as well.
51
:And then we've got the and for the
A, and then the P is polyols, which
52
:includes sorbitol, xylitol, mannitol.
53
:Sorbitol foods include
sweet corn, avocado, um,
54
:blackberries, and white cabbage.
55
:And the mannitol section includes
butternut squash, cauliflower,
56
:mushrooms, celery, and fennel.
57
:So What you might see from this
list of foods I've just Drawn out is
58
:that they're all healthy good foods.
59
:Like these are not food you want to
restrict long term So the process of
60
:the low FODMAP diet is not to restrict
these foods in the long term the way
61
:you approach the diet is to Follow
this low FODMAP elimination phase for
62
:somewhere between two to six weeks.
63
:This is to see if you feel better
without these fermentable carbohydrates.
64
:So if you feel better, you get less
bloating, maybe less diarrhea, less gas.
65
:That's a good sign and it
means you can continue.
66
:The reason it's up to six weeks is that
sometimes people find it takes a little
67
:bit longer to see improvements and you
probably would want to go up to at least
68
:two weeks and I find sometimes if you
have a bit of a slip up and you eat
69
:something high FODMAP you didn't realize.
70
:You might want to do another week,
or you might want to do a little
71
:bit more in order just just to
help you get a good baseline.
72
:That's what the first phase is all about.
73
:Establishing a good baseline and
reminding yourself of what good
74
:digestion should actually feel like.
75
:Then the important bit, the most
important bit that most people don't
76
:get to is the reintroduction phase.
77
:You wanna do a careful reintroduction of
higher FODMAP foods whilst monitoring.
78
:All your symptoms.
79
:This phase can take a really long time
because there is a specific way to
80
:do it with suggested extended periods
of reintroduction and increasing
81
:amounts and you need a bit of time
in between each trial to wash out
82
:and make sure that you are resetting.
83
:Most people do not go
through this process.
84
:Properly and they say I tried the low
FODMAP diet didn't work and I still
85
:don't know what my triggers are and that's
because of the reintroduction phase.
86
:Anyway, the final phase is your new
diet, which is a longer term eating plan.
87
:So including as many of the high FODMAP
foods as you can manage and excluding
88
:anything that triggered your symptoms
during that reintroduction phase.
89
:So who should not be
doing the low FODMAP diet?
90
:Well, firstly, if you haven't actually
got a diagnosis of IBS, I don't suggest
91
:starting with this low FODMAP diet.
92
:It's not the first thing that I would
try anyway, because it is complicated.
93
:, the first thing to do would be to
go to your doctor and understand if
94
:there's any medical tests you need and
make sure you get checked out before
95
:launching into a restrictive diet.
96
:If you haven't looked at the...
97
:Basics yet.
98
:I would also start there.
99
:If you haven't yet addressed, how
you're eating, looking at slowing
100
:down to eat, chewing, all the basics,
spacing out your meals, making sure
101
:you're getting a good nourished diet
full of protein, fats and carbs.
102
:Maybe if you haven't looked at other
factors that can really influence
103
:digestion, like alcohol intake,
caffeine intake, whether you've
104
:got sleep, is there any medication
that's upsetting your digestion?
105
:How is stress affecting you?
106
:These are all things I would start
with first, because these are like
107
:the baseline things that you can
do without the restrictive diet.
108
:And then the other time I would be very
cautious of starting a low FODMAP diet is
109
:if you have a history of disordered eating
or diagnosed eating disorder, if you have.
110
:an existing eating disorder, then you
should be working with somebody who
111
:understands your condition anyway.
112
:But if you have maybe a history of an
eating disorder, like it was in your
113
:teens and now you're in your 40s, there
is still a chance that following lots
114
:of diet rules could be quite triggering.
115
:And so, I think it's worth investigating,
maybe if you have a therapist talking
116
:that through, if you have a practitioner
you work with in terms of nutrition,
117
:making sure they fully understand
how that eating disorder has affected
118
:your current approach to eating.
119
:Because if you're following a lot of
rules, sometimes it can bring back some
120
:of those thoughts about controlling.
121
:If you've now listened to this
and thought, actually I do want
122
:to give it a go, it's worth a try,
here are some tips to get started.
123
:First of all, I would Start by
thinking about what you can eat.
124
:So really focusing on foods that you can
eat freely that are low FODMAP foods.
125
:These include things like rocket,
spinach, green beans, collard
126
:greens, olives, parsnips, papaya,
rhubarb, kiwi, green bananas.
127
:Oranges.
128
:You can eat lots of these as
well as things like potatoes.
129
:Protein does not have any of these
starches in it, so you can eat as
130
:much meat, fish, eggs as you like.
131
:and the low FODMAP diet is not a
caloric restrictive diet, so it's
132
:not meant for you to lose weight.
133
:The important thing is that you don't
get too hungry because that can also.
134
:Triggered IBS symptoms sometimes,
so you want to make sure that
135
:you know what you can eat lots of
136
:And then the next step is to identify
which foods are allowed in moderate
137
:amounts but You can't eat too much of
them, so you can have a small amount.
138
:This would be things like, a quarter of
an avocado is okay, but when you get to
139
:half an avocado, that becomes high FODMAP.
140
:This is why the diet is highly confusing.
141
:You will read blogs that say, Yes,
you can eat peppers, peppers are fine.
142
:Then you'll read another blog
that says, Don't eat peppers.
143
:They are high FODMAP.
144
:And this is because bell peppers,
there are different colors.
145
:There's red, yellow, orange, and green.
146
:And each of them has a different FODMAP
rating for the size of the portion that
147
:is allowable under the diet guidelines.
148
:So for example, with red peppers, you
can only have about 40 grams before it
149
:tips into a higher, moderate FODMAP.
150
:Whereas with green peppers, you can
have up to like 60 or 70 grams, I think.
151
:Before it becomes higher FODMAP.
152
:So you can have a lot more for
your portion because of the
153
:amount of fructose in the fruit.
154
:So it is all dependent on portion
sizing, and this is why it's good
155
:to understand what you can eat
lots of without worrying too much.
156
:And then what foods you
can eat in small portions.
157
:The other thing to know is that
this diet is not gluten free.
158
:It is not dairy free, but it does.
159
:Limit your intake of wheat due to the
high fructans and milk and high lactose
160
:foods such as yogurt and creamy cheeses.
161
:So you can have around 40 grams of hard
cheese, for example, which is not too bad
162
:a portion if you want to have a sandwich
or if you want to grate some cheese
163
:on your dinner or something like that.
164
:It's doable, but it's not.
165
:a huge portion.
166
:So if you're used to eating a
lot of cheese, you may find this,
167
:you know, just understanding what
40 grams of cheese looks like.
168
:And then my last tip on getting started
would be to make a plan of two to
169
:three versions in your head or on some
paper of breakfast, lunch and dinner.
170
:You want to know two to three things
that you can eat for breakfast.
171
:Maybe a nice weekend one that might
be a bit more tasty and time consuming
172
:and something else that's really
quick that you know you can prepare
173
:the night before or that you can do
quickly in the morning before work
174
:or taking the kids out, whatever.
175
:And then do the same for your lunch
and your dinner so that you've
176
:just got a couple of options that
you Understand how to make them
177
:and you understand what to do.
178
:The final thing to remember in terms
of like quick tips for getting going
179
:is that this phase of restriction
is only for two to three weeks.
180
:It is not forever.
181
:If you can just get through this week,
the first week is probably the hardest.
182
:And once you've established.
183
:A little bit of a routine,
you'll feel a bit more confident.
184
:I'm going to record a part two of
this podcast, specifically about the
185
:reintroduction phase, because that is
one of the most tricky parts of the diet,
186
:and I want to give it sufficient time.
187
:But, whilst you're in this low
FODMAP phase, the first bit, where
188
:you're just cutting everything out,
a couple of things to help you.
189
:One would be...
190
:Thinking about FODMAP stacking.
191
:If you have more than one portion of
a moderate FODMAP in a meal, and you
192
:add it to another portion of another
moderate FODMAP meal, it could make it a
193
:high FODMAP meal without you realising.
194
:So, as an example, two
tablespoons of apple is about
195
:moderately high for sorbitol.
196
:The same as a quarter of an
avocado, or half an avocado, might
197
:be moderately high with sorbitol.
198
:If you're adding these together in
the same meal, you could end up with a
199
:higher FODMAP meal without realising it.
200
:So this is one of the traps that
people can fall into, is putting a meal
201
:together including lots of small or
moderate portions that actually then
202
:will add up to be a higher FODMAP meal.
203
:This is where keeping as much
diversity in your diet as possible
204
:is really, really helpful.
205
:You also need to be aware that some foods
do contain more than one type of FODMAP.
206
:So, like apples, I just mentioned, have
got sorbitol and fructose, and cashew
207
:nuts have got gauze and fructans.
208
:And this can make it more confusing
when you're trying to work out
209
:what you've actually eaten that
might have triggered your symptoms.
210
:You must also remember
that you are not a machine.
211
:You may not react to foods in
the same way that a machine did
212
:when the foods were classified
in terms of their FODMAP content.
213
:The Monash University in Australia
is where the FODMAP diet was created,
214
:and the way they measure the amount of
FODMAPs in food is by some standardized
215
:processes that shows the amount of sugar
in grams per hundred grams, and they look
216
:at the particular sugars, like fructose
and lactose and that sort of thing.
217
:And whilst they do try and pick a
selection of foods, like I think they
218
:have five different supermarkets or
five green grocers and they pool it
219
:all together, or they might, you know,
choose the main brands that are available
220
:on the market, they are choosing
things that are from the Australian
221
:market mostly, and there can be some
difference in when the food was picked.
222
:So if we think about tomatoes, they can
taste completely different if they are
223
:slightly underripe and they've been kept
in the fridge or if they've been out
224
:in the sun, getting all ripe and juicy.
225
:It depends on the variety that's used.
226
:It depends on the climate
that the food was grown in.
227
:The season that the food was grown
in, whether it was force grown
228
:under polytunnels or naturally
grown because it's the season.
229
:How long the food has been
stored before it was tested.
230
:So all of these things you can see
can affect the potential to have
231
:higher FODMAPs in a food that may be
classified as low to moderate FODMAP,
232
:but may still give you a reaction.
233
:And that is because You can't
standardize everything that you eat
234
:and compare it to something that has
been tested in a lab in Australia.
235
:Now that doesn't mean it's not accurate.
236
:They have done so much work into
how these FODMAPs affect your gut
237
:and what particular cutoff point is
thought to induce symptoms in people.
238
:So there is so much
research behind this diet.
239
:However, It may be an individual
response to a certain food that
240
:could still trigger your symptoms.
241
:And this is down to individual
genetics, your own digestive processes,
242
:maybe other health conditions, your
mental state when you're eating.
243
:All of these things could have some
impact on your ability to digest your
244
:food and that's why there is some trial
and error expected in the low FODMAP even
245
:if you follow the diet to the letter.
246
:It is not an exact science, and I know
that can feel very frustrating when
247
:you are trying so hard, but you're
not seeing any of the improvement.
248
:The other thing to remember is
that it might not be FODMAPs in
249
:the food that is the issue for you.
250
:There are other kind of triggers in
foods that can set off IBS like symptoms,
251
:including histamine, salicylates, which
is in things like oranges, berries,
252
:sweet potato, broccoli, almonds, and tea.
253
:Alcohol intake, that can be a real
trigger if you are drinking a lot of
254
:alcohol alongside the low FODMAP diet.
255
:Sometimes dairy, and it can be like a
dairy allergy that's been undiagnosed,
256
:or maybe you just can't even tolerate
small portions of the lactose.
257
:it could be a problem
with gluten intolerance.
258
:Other things in foods like soy and
corn or other allergens that are known
259
:to be a problem for people like eggs.
260
:And this is where the sulfur content of
food may be an issue for some people.
261
:So if you find that things like
onions and garlic and processed
262
:meats, that kind of thing, are all
triggering for you, consider whether
263
:sulfur might be a problem as well.
264
:I just listed those things out, that's
not an exhaustive list of other things
265
:that could, but it's a Common list of
things that I will cycle through in
266
:my mind when working with somebody who
says the low FODMAP diet doesn't work.
267
:Other issues that are worth
considering, if you feel like the
268
:low FODMAP diet doesn't work for
you, is to think about gut bacteria.
269
:This is really important because these
are the things that are helping to
270
:break down the fiber in your diet.
271
:If you have a lack of the beneficial
bacteria, or you have an overgrowth
272
:of pathogenic or like bad bacteria,
or maybe some particular strains
273
:are overgrowing out of control
in your small or large intestine.
274
:These can affect your ability to
process fibres and you may find
275
:you're reacting significantly
to carbohydrates in your food.
276
:Then the last two things that you
should be aware of is maybe you've got
277
:a problem with gut motility, so that
migrating motor complex that comes
278
:to sweep out your small intestine.
279
:That should be happening.
280
:And if it doesn't, it may lead to
an increase in bacteria overgrowing
281
:in your small intestine that can
impair your digestive enzymes.
282
:So motility in terms of fast transit
time or a slow transit time can really
283
:affect your ability to digest the
food and can lead to IBS symptoms.
284
:So whether you've got fast or slow
transit time, some of that, yes, is
285
:affected by diet, but it might also be
affected by nervous system issues, by,
286
:a lack of maybe movement if you're not
actually doing any exercise, that can
287
:lead to slow digestion, for example.
288
:And then finally, the visceral
hypersensitivity that's so common, so
289
:that gut brain connection, thinking
about your gut's nervous system, you
290
:may be experiencing heightened sensation
of pain, , and Experiencing more
291
:sensations of gas and movement within
your body than other people could.
292
:And it might not have anything
to do with the FODMAP, so it
293
:might be almost like your gut's
nervous system, that is the key.
294
:And in that case, you should work
on your vagus nerve, um, other
295
:nerve system support in terms
of managing anxiety and stress.
296
:And also be aware of how hypervigilant
you are, which can be a bit of a
297
:conundrum when you are doing this diet
in order to focus on your symptoms.
298
:And yet, if you're someone who's sort of
symptom obsessed, it can be pretty tricky.
299
:I'm going to leave it
here for this episode.
300
:The next episode will all be about
how to do that reintroduction, what
301
:you'd be looking for, what kind of
things you can do in order to know
302
:whether FODMAPs are your trigger and
if they are which particular ones.
303
:So do join me next time for a bit more
on the FODMAP reintroduction process.
304
:See you then.
305
:Goodbye.
