There is fairly high confidence that there is little connection
between poor diet and Ulcerative Colitis/Inflammatory bowel
disease (IBD). This should not be confused with Irritable
Bowel Syndrome (IBS) - caused almost entirely by a poor diet
high in processed foods and low in dietary fibre.
In spite of this diet has a large part to play in minimizing the
effects of Ulcerative Colitis - and in the treatment of flare-ups.
Care must be taken though with Colitis - as a good diet for a person
with colitis differs slightly from that of a person without colitis.
Fibre - and Ulcerative Colitis
There is much confusion in the advice given to people about dietary
fibre and ulcerative colitis. To understand this properly it is
important to appreciate there are two distinct types of fibre. One
- soluble fibre should be encouraged when suffering from colitis
- the other - insoluble fibre tends to inflame colitis and should
be avoided.
Insoluble Fibre - Detrimental for Colitis
Insoluble fibre is generally bad for ulcerative colitis/IBD sufferers.
This is the type of fibre that most people would associate with
a high fibre diet. Examples of this type of fibre include -
- Wheat bran/wholemeal bread/bran flakes etc.
- Cabbage
- Broccoli
- Sweet corn
- Skins peel of vegetables such as apples and grapes
This type of fibre passes through the whole of the digestive tract
without being digested - and hence has a tenancy to adhere to the
wall of the colon when it is inflamed. This irritates the colon
- and hence will aggravate any colitis. As a rough guide if you
can see particles/undigested matter in the stool this is insoluble
fibre.
Soluble Fibre - Beneficial for Colitis
Soluble fibre is very helpful for colitis and differs from insoluble
fibre in that it is broken down/digested in the large intestine/colon.
This produces a soft stool and good motions - but does not produce
the type of particles that adhere to the bowel wall and cause inflammation.
Good examples of soluble fibre include
- The body of fruits - e.g. peeled apples, peeled pears
- Peeled Vegetables - e.g. peeled potatoes and carrots
- Oat bran - e.g. porridge/Ready Brek
- White rice
Fish Oils and Ulcerative Colitis
Fish oils - especially from oily fish such as sardines and sild
have been shown to have a beneficial effect on colitis. This is
because they help to reduce inflammation generally - and they also
have a topical effect on the bowel as they pass through. In order
to include fish oils in the diet it is recommended that actual fish
be used rather than dietary supplements. Sardines especially are
very cheap, nutritional - and contain large amounts of the required
oils.
Dairy products and Ulcerative Colitis
Those that suffer from ulcerative colitis should avoid excessive
amounts of dairy products such as cheese/cream etc. This doesn't
mean that they have to be avoided totally - just some common sense
used. I would suggest that probably about 2-3 ounces in a day is
about the limit. Quantities beyond this are likely to lead to lactose
in the colon - which will encourage unhelpful bacteria and inflammation.
Foods to Avoid when you have active Ulcerative Colitis (Flare
Up)
There are a number of foods which are best avoided during a flare
up of Ulcerative Colitis - or when Colitis is active (i.e.
blood or mucous in the stools). These are mainly foods that
either include a high amount of insoluble fibre - or very
high amounts of dairy fats-
Cabbage/sprouts
Cauliflower
Broccoli
Sweet Corn
Mushrooms
High Bran fibre items - such as wholemeal bread, and high
fibre cereal
Raw onions
Tomatoes - especially the seeds
Soya Protein (TVP)
Onions - Especially raw onions
Cheese/cream (tends to cause excess acid/irritation in the
gut)
