Allergy or Food Intolerance

There comes a time when a negative reaction to food becomes a very real health concern. That time is when your immune system decides to become involved and the tummy ache you had last week turns into a serious allergic reaction to your dinner this week.

It is estimated that in the United States there may be as many as 15 million people who suffer from food allergies and of these approximately 100 to 200 allergy sufferers will lose their life each year in an acute reaction to the food they consume. Those are the extreme cases but food sensitivities are not an issue that anyone should take lightly.

It can be important to know if your tummy ache is just a tummy ache or if it is a signal to something potentially more. More serious symptoms could signal a food intolerance or a possible allergy reaction to one or more foods that you are consuming. At times it can be difficult to know if that after dinner bloating is a simple consequences of consuming a little too much food or potentially something more serious.

The main difference between food intolerance and an allergic reaction is the involvement of the immune system.

Our immune system is designed to fight potential threats within the body. It is an amazing defense mechanism designed to protect the body from illness. Germs, bacteria, infection and disease, are all attacked as they are detected.

Every now and then though something goes wrong and the immune system is over sensitive resulting in it confusing basic non threatening foods as a threat to its security.

The immune system creates antibodies to fight the offending substance and future ingestion of this triggering agent then result in the immune system launching a more aggressive attack against the intruder. The immune system releases a chemical battle which is the cause of the symptoms involved in an allergic reaction.

Symptoms can vary quite dramatically from mild to severe.

The symptoms of an allergic reaction can be mild and involve nothing more than a tingling of the lips, a runny nose, a tummy ache. or a slight rash. Reactions can also include breathing and swallowing difficulties, hives, reddening or itching of the skin, eyes or throat, or very serious involvement of the cardiovascular or respiratory system.

A severe reaction can cause swelling of the tongue, larynx, and trachea resulting in an inability to breath followed by collapse. An allergic reaction can be very dangerous. It can be severe enough to result in death.

This is why it is so important to recognize when you are indeed suffering from an allergic reaction. Your immune system may increase its attack and the next ingestion could be much more severe than the one that you suffer in the first few encounters with the triggering agent. This is the second major difference between a food intolerance and an allergy.

A food intolerance may have uncomfortable consequences

but it is rarely dangerous where as allergies can be extremely hazardous to your health.

Although the symptoms of intolerance may sometimes appear the same as those involved in a mild allergic reaction with gastrointestinal discomfort appearing in the form of indigestion, flatulence, bloating, acid reflux, diarrhea, loose stools or other similar symptoms. These symptoms usually do not progress past being uncomfortable and are usually just caused by our difficulty in digesting certain foods.


Negative consequences of milk consumption often occur due an intolerance to lactose but this generally does not involve the immune system. 

Consult with your doctor if you suspect a food allergy. A blood test can often confirm the presence of immunoglobulin-E (IGE) antibodies produced by the immune system and specific to the food groups that trigger the allergic reaction.

A skin test can also be performed where small amounts of the offending food product are injected just under the first layer of skin. A skin allergy to that substance will usually result in a rash or hive appearing at the location of injection indicating an allergic reaction.




The best way to control a food intolerance or a food allergy is to remove the offending food from the diet. By participating in an elimination diet plan you may be able to pinpoint the specific edibles at issue.
