Gluten Intolerance
Year 11 Integrated Science
Food Science
More than 55 diseases have been linked
to gluten.
 We will look at:
-Coeliac disease
-Gluten sensitivity

What it is?

Gluten intolerance is when a person cannot
tolerate gluten, a protein found in wheat,
rye, oats and barley products.
Coeliac disease
Coeliac disease is not an allergy. It is an
autoimmune disease, which means that the
body produces antibodies that attack its own
tissues.
Essentially the body is attacking itself every
time a person with celiac consumes gluten.

Remember : Digestive system
Small intestine
Large intestine
Cause : Coeliac disease

When people with coeliac disease eat
gluten, the villi become damaged. They
become inflamed and then flattened,
leaving less surface area to absorb
nutrients.
Let’s have a closer look!…
Symptoms
What to do?
Coeliac disease is treated by a lifelong gluten free
diet.
Once gluten has been removed from the diet, the
process of gut healing will begin and the lining of the
small bowel to recover completely.
However, it can take up to two years or more for
the gut to recover completely and the absorption of
nutrients to get back to normal.
How to test?
Biopsy/endoscopy
Gastroscopy procedure in
which several tiny samples
(biopsies) of the small bowel
are taken
Blood test
‘Coeliac serology’ measures
antibody levels in the blood
Gene testing
Gluten sensitivity?

Describe individuals who cannot tolerate gluten and
experience symptoms similar to those with celiac disease.

They don’t have an intestinal damage as seen in coeliac
disease.

The science on gluten sensitivity is evolving. New research
suggests that gluten alone may not be responsible for
the symptoms produced.

FODMAPs, a group of poorly digested sugars, may be the
cause of the symptoms instead. (wheat, barley and rye are
high in FODMAPs) (FODMAPs :fermentable, oligo-, di-,
monosaccharides and polyols).

The people in the study did not see their intestinal
symptoms worsen with pure gluten.
Quiz!!!!!!

malt is derived from the glutencontaining grain barley.
Gluten-free?
Remember

The issue: Reaction to gluten The disease: Coeliac disease

It is an autoimmune disease, which means that the body
produces antibodies that attack its own tissues : the body is
attacking itself every time a person with celiac consumes gluten.

Symptoms include digestive issues, fatigue, dizziness, headaches,
mood issues, joint pain, eczema …….

The only treatment for celiac disease is a strict, lifelong
gluten-free diet.

Gluten-free alternatives are now made with potato, rice, soy, or
bean flour. In addition, plain meat, fish, fruits and vegetables are
naturally gluten-free.
