An App to Help Find Allergens in School Lunches

Working for a company that treats food allergies, I’m always on the lookoutfor Facebook posts, allergy blogs, or practically anything related to allergies.

Nutrislice App

Today, I ran across a really cool app while reading my son’s school monthly newsletter.  Our school district has adopted the use of an app called Nutrislice.  I can digitally find the school menu for the month, and with a few clicks I’m able see a real picture of the food with a description, nutrition information, and allergen information.

For example, on Monday, my son will have the choice of a Classic Chicken Sandwich or a PB & Grape Jelly Uncrustable as a main item.  Good for him to be able to see the options, along with pictures.  Great for a mom who may be dealing with a child with food allergies.  I can tell that the chicken sandwich contains both wheat and soy, and the pb&j contains wheat, soy, and peanuts.  We can also see  the nutrition information for all of the sides, milk choices, and condiments.

For our family, this is a great tool to plan lunches for the week, and for my son to determine if school lunch really looks gross or not.  (OK- the turkey nachos don’t look appetizing, so I can’t blame him for not liking that choice!)

For food allergy families, this app could literally be a lifesaver!  Kudos to our school district for providing this app!

Research for alternative testing method for food allergies looks positive

According to a new study published in the journal Scientific Reports, researchers have developed an alternate method to more accurately detect and identify the presence and severity of peanut allergies, without directly exposing patients to the allergen.

A team of chemical and biomolecular engineers at the University of Notre Dame designed nanoparticles, or “nanoallergens”, that mimic natural allergens by displaying each allergic component one at a time on their surfaces.  These nanoallergens are used to dissect the critical components of major peanut allergy proteins and evaluate the potency of the allergic response using the antibodies present in a blood sample from a patient.

“The goal of this study was to show how nanoallergen technology could be used to provide a clearer and more accurate assessment of the severity of an allergic condition,” said Basar Bilgicer, associate professor of chemical and biomolecular engineering and a member of the Advanced Diagnostics and Therapeutics initiative at Notre Dame.  The goal of this new testing procedure is to replace the oral food challenge; which requires a patient to ingest small amounts of the offending food to the point of intolerance or anaphylaxis; and skin prick testing, which may have false-positive test results.

“We are currently working with allergy specialist clinicians for further testing and verification of the diagnostic tool using a larger patient population. Ultimately, our vision is to take this technology and make it available to all people who suffer from food allergies.”

Autism Spectrum Disorders and Food Allergies

In honor of the upcoming World Autism Awareness Day on April 2, I wanted to share some information regarding autism spectrum disorders (ASD) and food allergies.

 

General Information:

IgE-mediated allergic diseases (e.g., allergic rhinoconjunctivitis, atopic asthma and food allergy) are among the most common chronic conditions worldwide, and are continuing to rise each year.  In addition to easily recognized symptoms, such as a runny nose, itchy eyes, sneezing and coughing, allergic diseases can cause neuropsychiatric symptoms, such as irritability and hyperactivity, in otherwise healthy individuals. This is also likely to occur in children with autism spectrum disorders (ASD). Moreover, the discomfort and pain associated with allergic diseases could aggravate behavioral symptoms in ASD children. [1]  This may be due the child’s inability to communicate or fully understand or explain his or her discomfort.

 

Allergy Testing:

Autism spectrum disorder children are known to suffer from additional issues, with gastrointestinal (GI) and sleep disorders being the most common. It may be useful to test for food allergies to confirm or rule out allergies as a cause for GI issues.  Allergy testing can be done by skin testing or blood work.  Many times these tests indicate that children do, in fact, have true allergic responses to foods. Other times, the tests come back “negative” for food allergies.

 

Allergy Treatment:

If a patient tests positive for food allergies, they can be treated with sublingual immunotherapy (allergy drops), by avoiding the allergy-inducing foods altogether, or a combination of both.
