Food Sensitivities

Food sensitivity testing near you in Highland Park

Is it a food allergy or sensitivity?

The word “allergy” can be confusing because many people use it as a fully encompassing generic term. The term tends to apply to true allergic reactions and nonallergic adverse reactions, also called sensitivities or intolerances.

Immune reactions can result from the different types of food allergies or food sensitivities you may possess. The most common foods causing allergic reactions are peanuts, soy, wheat, shellfish, fish, milk, eggs, and tree nuts. Once identified, we recommend eliminating those problematic foods from your diet.

Oftentimes, if you have a sensitivity, you may not even know it. It may be subtle, like bloating or feeling tired after you eat. These sensitivities cause chronic inflammation in our bodies, preventing them from functioning optimally. Symptoms range from rashes, constipation or diarrhea, feeling tired, or gaining weight.

How it works


When an immediate food allergy reaction occurs, sufferers experience symptoms within hours of having ingested the food. Symptom onset is rapid and may include a variety of effects. These include tingling of extremities, wheezing, coughing, tightening of the throat, nausea, abdominal cramps, and diarrhea. Sometimes in cases where nuts, shellfish, fish, and peanuts have been eaten anaphylaxis can occur. An immediate food reaction is a fixed food allergy.

The food to which you are allergic will almost always provoke an immune reaction when ingested.


A food sensitivity, as opposed to a food allergy, happens gradually and isn’t life threatening. Symptoms of a delayed food allergy can take up to 72 hours to appear. This type of immune response is mediated by the IgG antibody, which is the largest circulating antibody in our immune system and can cross the placenta from mother to child. IgG antibodies are the most common form of immunologic mediated food responses. It can be difficult to identify the offending food since we eat so many foods that go through different processes and have many ingredients. It is estimated that 20% of the population have an adverse reaction to a certain food.

Food sensitivities may be caused by many factors such as stress, infections, overeating, artificial preservatives, additives, molds, pesticides, antibiotics, and environmental pollutants. Unidentified food sensitivities can then contribute to many chronic health conditions including irritable bowel syndrome, rheumatoid arthritis, headaches, ADD/ADHD, eczema, gut malabsorption, insomnia and more.

After a quick blood test done in our office, you blood sample will be sent to Alletess Medical Laboratory, which uses state of the art technology to identify the offending foods in your diet. You will be given a report showing 184 different foods to which you may be sensitive to, as well as the severity of the sensitivity. You will also be given a complete booklet ellaborating on your food sensitivites.
