Increased Protein Digestion Reduces Food Allergenicity 
From Dr. Houston:

Dr. Devin Houston, Ph.D.


Food intake, considered a pleasure by most, also represents a health hazard in situations where metabolism is altered or if food proteins are recognized as harmful by the immune system.  In the latter case, IgG, IgE and IgA antibodies are produced by the immune system in response to the food "attack".  The number of food-allergic patients is increasing, as is the severity of the reactions.  The effects range from mild rashes, diarrhea, and/or migraine headaches to all-out systemic dysfunction. 


One of the functions of the digestive tract is to change food into a substance that won't trigger the immune system to launch an attack. 


Several methods are used in the body to accomplish this task.  Stomach acid denatures food proteins.  Denaturation removes the "glue" holding the structure of the food protein together and often results in loss of any function associated with the protein. 


However, even denatured proteins can be allergenic.  The next and most definitive step for rendering food proteins harmless is enzymatic degradation that begins in the stomach but predominates in the small intestine. Denaturation actually sets up the protein for optimal break down by protease enzymes. 


The immune system in the gut is triggered by a number of factors but size of the offending protein is the most predominant.  The larger the protein, the more likely it is to set off the alarm for IgG antibody production.  Conversely, smaller proteins or fragments are able to slip under the radar for immunity activation.  Research from several labs demonstrate that when protein digestion is compromised, antibody production to that food protein increases.1-3


A compromised digestive system can occur easier than one may think. 


The simple act of taking an antacid reduces the activity of pepsin, the major protease enzyme in the stomach, by raising the pH of the stomach over 5.0.  Many on H2 blockers have increased food allergy symptoms because the resulting low stomach acid fails to activate the pepsin enzyme system. 


Larger food protein fragments are then passed on to the intestinal tract and have the potential to become allergens.2-4 Conversely, research indicates that pre-treatment of food proteins with protease enzymes results in a less allergenic potential.5, 6   Heating of a protein alone will not break down a food protein sufficiently, so cooking is no guarantee of...

New! TriEnza Powder

Our popular TriEnza broad-spectrum enzyme product is now available in powdered form for easy mixing in food or drink. Economical, too.TriEnza Powder

Same great enzyme formula as our TriEnza capsules. One dose of TriEnza Powder is 1/4 teaspoon or 584 mg -- or a slightly heaping scoopful of the enclosed scoop. A dose is equivalent to 2 TriEnza capsules.

  • Cost savings per dose over capsules and chewables
  • Same powder as our TriEnza capsules - no added fillers or flavors
  • Broad-spectrum digestive support for all foods
  • For digestion of proteins, carbohydrates, fats and phenols
  • High in DPP IV for gluten, casein, soy and other sources of exorphin peptides
Keep in mind that enzymes are proteins, and anyone can become allergic to any protein. Minimizing skin exposure to enzymes as well as ensuring that the powder is not inhaled or rubbed into eyes helps prevent possible sensitization reactions.

 quotation marksFrom the earliest days when issues of maldigestion and malabsorption were recognized as problems for children with autism spectrum disorders, Devin Houston, PhD was in the forefront of research identifying beneficial enzymes to combat the problem. There are very few people we consider an expert in any issue related to autism (since we are all on the steep part of the learning curve when it comes to this medically-based disorder), but Dr. Houston is indeed an expert in the use of enzymes in conjunction with, or instead of, restricted diets for children on the spectrum.  


Dr. Houston's dedication to the kids is apparent as he strives to help caregivers understand not only what they can do for their loved ones with autism, but why they should do it.  He is five questions deep on every topic related to enzymes and, given that roughly 70 percent of children with ASD have digestive issues, he is a must-see for anyone with autism in the family.

Q and A with Dr. H

Your questions answered by Dr. Houston:     

Q: Sometimes a bottle of enzymes seems slightly darker or lighter.  Is that normal?

A: Yes, color can vary from lot to lot, and is always given consideration during organoleptic testing.  It is quite natural to have color variations in the enzyme powders and it has no bearing on potency or activity.     

Q: What foods can be mixed with enzymes?


A: You may mix with any food or drink, as long as temperatures do not exceed 150 degrees.  If the food is cool enough to eat, it's cool enough for enzymes.  Keep in mind that if the enzymes sit on some foods for long, the food texture will change as it is broken down.  A list of food and drink ideas for mixing can be found at our site.  

Q: Can enzymes have an effect on urinary pH levels?


A:  Enzymes have no direct effect on urinary pH.  The foods we eat may affect pH slightly, but the enzymes only break down foods which should not be a factor in urine acidity.
