Many
people love to wake up to their morning cup of coffee. They simply cannot get
going until that first cup has passed their lips. But is safe for celiacs to
drink coffee? Coffee fanatics love the taste, they love the aroma and they love
to routine; not to mention they love the morning caffeine hit. Some of my
customers when I owned Bacio Café would come back for 3-4 cups in the morning!
Well
the fact is that pure coffee beans are gluten free and perfectly safe for
celiacs. You can buy them as beans or pure ground beans and they will be safe. If
you make your coffee at home you are in control of what goes into it. And you
can easily read the label on the packet to see if there are any other
additives. Using organic, whole-bean is definitely recommended.
But
it is a bit more difficult if you get your coffee from the local café, because the
problem is that many coffees are NOT pure, not organic and they can pose a risk
to the celiac. There is also a risk of gluten cross contamination if the
barista does not understand what it means to be gluten free. I have highlighted
some of the things to watch out for when ordering your coffee.
Many
of the coffee flavorings also known as monins, such as caramel (caramel latte)
and vanilla, (vanilla latte) are NOT gluten free. It is essential to check the
label to ensure any additives to your coffee are gluten free. This also applies to milkshake flavorings -
they are often NOT gluten free either.
Plain
unadulterated milk is also gluten free, but when it comes to soy milk you need
to be very careful. Not all soy milk is gluten free, and so once again, you
need to find out the brand you or your local café is using and check the label.
The
other additive commonly added to coffee is chocolate, either sprinkled on the
top of a cappuccino, or mixed in a mocha, or even just pure hot chocolate could
be the source of gluten contamination so a celiac must check it all out. Not
many baristas will be aware of the hidden sources of gluten when they make your
coffee, mocha or hot chocolate so it is up to you to check it all out.
But
recently, there have been some reports that perhaps those with celiac
disease should not drink coffee. An article on Facebook titled “Gluten Issues
or Celiac: Don’t Drink Coffee” reports:
“In a nutshell, fairly
recent lab research has revealed that 10% of coffee is a protein that
cross reacts with gluten antibodies.”
But
is this really true? If you’ve been eating a 100% gluten free diet and
are still experiencing gluten related symptoms, the problem may be your coffee
intake. That being said, there are actually several foods that cause some
sort of reaction in those who are sensitive to or intolerant of gluten. This is
because the proteins in these foods are perceived by the body as invaders in
the same way gluten is.
There
are several foods that cause what’s called a gluten cross-reactivity in those
who are sensitive to or intolerant of gluten. This is because the proteins in
these foods are perceived by the body as invaders in the same way gluten is.
Dairy
is the most common cross-reactive food for those with gluten issues, because of
its casein proteins. But coffee also contains problematic proteins and the
cross reaction to coffee has actually been found to be one of the most severe.
In
a study published in Food and
Nutritional Sciences, researchers found this reaction was limited to
highly-processed coffee, such as instant coffee, ground coffee and flavoured
coffee. What researchers believe is that the processing itself contributes to
the problem because organic, whole-bean coffees do not produce
cross-reactivity issues. While more research is needed, it’s thought that
the proteins in coffee are changed in such a way during processing that the
body perceives them as a threat, which causes the same inflammatory responses
and symptoms as gluten in those that are sensitive or allergic to it.
But
this same reaction can also occur in people who do not have celiac disease so
is it caused by a gluten reaction or a totally unrelated reaction to coffee
proteins? The processing of dairy products
is also known to cause a gluten-like reaction due to the changes to dairy
protein.
Common
coffee symptoms include migraine, mental fogginess and fatigue. Unfortunately,
when people experience these symptoms, they reach for yet another cup, which leads
to more symptoms. Add to this the fact that most people also add some form of
dairy to their coffee, and you now have two potential ways they could be having
cross reactive gluten like inflammatory damage.
The
possibility is that you are actually allergic to some other sort of food or
coffee additive is also a possibility. Contaminants in the coffee could also be
a cause of the symptoms.
Mycotoxins
Another
possible problem with coffee is that they may be contaminated with mycotoxins. Coffee
beans are often contaminated by a toxic mould known as ochratoxin A, which
produces these mycotoxins. Roasting the coffee tends to reduce the natural
levels. Most people do not react to it, but some others can have a severe
reaction to it. It seems to affect people with celiac disease more often than
the normal population. But once again this is not a reaction to gluten but a
totally unrelated reaction.
Pesticides
Coffee
crops are often heavily loaded with pesticides. Pesticides can cause
intestinal damage, leaky gut, and disrupt hormones (especially
estrogen). That is why it is best to drink organic coffee only.
Caffeine
The
caffeine content in coffee ranges from 100-200 mg per serve depending on the
type and strength of the brew. Caffeine is a common gastric irritant and
can lead to mucosal degradation in the stomach and oesophagus. Some people who
have gluten induced gastrointestinal damage may also have problems with regular
coffee consumption. Caffeine can also overstimulate the adrenal glands
which can be very detrimental for someone already suffering with adrenal
burnout or adrenal insufficiency. You may need to eliminate caffeine for
several months while your body is recovering.
It
can be hard for people to pinpoint the problem, because pure coffee is a gluten
free food. So if you are not feeling better on a 100% gluten free diet coffee
is a factor you need to consider. Stay off coffee for 2-3 weeks to allow the
coffee residues to be eliminated from your body. Hopefully you will show some
improvement.
Then
do a challenge test by introducing coffee back into your diet. Start with just
one cup in the morning, but make sure you use pure, organic, whole-bean coffee.
If your symptoms diminished or went away entirely after a couple of weeks
without coffee and your one cup of whole-bean coffee doesn’t produce any
symptoms, then it’s safe to say that you can go back to your normal coffee
intake, but stay away from instant and ground coffees and make sure that any
flavorings and chocolate sprinkling is gluten free.
Using
organic, whole-bean is definitely the better choice, and there are plenty of
interesting and exotic organic beans for you to discover. The upside of this is
that freshly ground coffee is superior in taste and aroma, and so, you can remove
your symptoms and still enjoy a great cup of coffee.
If you want to make sure your local cafe of restaurant is preparing your gluten free coffee and food correctly, pass on this book which details all the procedures they need to take to achieve 100% gluten free. Many of them certainly need this education to ensure you are safe!
