Regardless of the terms currently used,
the fact is that some of us have adverse reactions when we eat citric acid, and sometimes when
we put it on our skin. Citric acid is frequently made from Corn, and I believe that often a
reaction to corn is actually a reaction to the citric acid that is in the corn. Citric acid is
found in MANY foods naturally, and not just citrus fruits as most people
think.
It is also used as a cleaner and descaler
in concentrations around 6% to remove hard water stains from surfaces, and it is also used to
slow the rate at which concrete sets, so you can see it has many industrial and household
uses.
In food, citric acid frequently used as a
preservative, and many vegetable and fruits are washed in a mild citric acid solution to
prevent them going brown (and looking less appealing to shoppers) by reacting to oxygen in the
air (oxidization). It is also used as a flavoring to make foods taste tart, and is sometimes
used in place of lemon juice by food manufacturers.
You'll see it on the ingredients list of
many canned drinks, including many colas and root-beers. How Much in the World? In 2007 there
was an estimated 1,700,000 tons (that's 3,400,000,000 or three point four BILLION pounds) of
citric acid produced, most of it made in China.
Where did all this go? Here is the
breakdown: Half of it was added to drinks, 20% as food additives , another 20% added to
cleaners and the last 10% is estimated to be added to cosmetics, like shampoos and soaps. As
you can see, it isn't just something quite rare tat you find in a few things, but rather is
extremely common.
So what exactly IS the difference between
an allergy and an intolerance? Well, here is what I have managed to gather from my studies. To
be an allergy, technically, your immune system has to be involved. That is, something has made
your immune system start to do its job and try to protect you. The problem with allergies is
that too often, your immune system seems to start doing its job when it doesn't need to,
because it reacts to things that aren't really very harmful to you, such as
pollen.
A food intolerance (or food sensitivity)
on the other hand, is a body's inability to digest certain compounds in food, but does NOT
involve the immune system. The reasons that this happens seems to be caused by several factors,
and more research needs to be done to determine what all of these factors
are.
It's vitally important to determine
whether or not you do indeed have an allergy or intolerance, and the only way to do this is to
see a licensed doctor, preferably an allergist or other specialist in that field. Allergies can
be life threatening (hence me saying it's VITALLY important) and many people are now prescribed
"epi-pens" which are syringes full of epinephrine, which they must administer to themselves (or
have others do it for them) if an attack happens when you aren't near a physician (which is
most of the time of course).
There are several common food
intolerances, including Lactose Intolerance - which means you can't drink milk or eat milk
derived products, and Gluten Intolerance - which means you can't eat breads or any products
made with grasses, such as Wheat or Rye.
I've spoken with several doctors and
citric acid intolerance (often called citric acid allergy) seems to be new to many of them.
While this probably isn't a life threatening condition, because of its symptoms, it can be very
debilitating, and quite often very embarrassing.
