Understanding Food Sensitivities and Allergies

Food sensitivities and food allergies are two terms often used interchangeably, but they refer to distinct immune responses in the body. In this blog post, we will explore the difference between food sensitivities and food allergies, with a focus on IgG and IgA antibodies. Additionally, we will delve into the impact of inflammatory foods on gut health and touch upon oxalates and salicylates. Let’s dive in!

Food Sensitivities and Food Allergies:

Food sensitivities and food allergies are both immune reactions triggered by certain foods, but they involve different components of the immune system. Food allergies are immediate and often severe reactions mediated by the IgE antibody, leading to symptoms like hives, difficulty breathing, and even anaphylaxis. In contrast, food sensitivities are delayed reactions that involve IgG and IgA antibodies, resulting in a range of symptoms that may affect various body systems, including the gut.

Gut Health and Inflammatory Foods:

Certain foods can have an inflammatory effect on the gut, exacerbating food sensitivities and contributing to a range of health issues. For example, in some individuals, casein (a protein found in dairy) and gluten (a protein found in wheat, barley, and rye) can be broken down into morphine-like compounds called casomorphins and gliadorphins, respectively. These compounds can bind to opiate receptors in the brain, potentially leading to ADHD symptoms such as spaciness, brain fog, fatigue, irritability, moodiness, anxiety, depression, and sleep problems.

The Role of Digestive Enzymes:

In individuals with inactive dipeptidyl peptidase-IV (DPP-IV), an enzyme responsible for breaking down casein and gluten, the levels of casomorphins and gliadorphins can become elevated. This can be further compounded by zinc deficiency. To address this, a dietary approach involving the elimination of gluten and casein is highly recommended. Additionally, supplementation with digestive enzymes is beneficial. 

IgG Food Allergies and ADHD:

Delayed hypersensitivity reactions mediated by IgG antibodies have been associated with symptoms commonly seen in ADHD. These symptoms may include hyperactivity, inattention, impulsivity, irritability, and mood fluctuations. If IgG-mediated food allergies are suspected, an IgG food allergy test from a reputable laboratory like Great Plains Lab can be ordered to identify problematic foods.

Food Sensitivity Assessment and Management:

To assess food sensitivities, it is essential to observe if there is a strong craving or dependency on specific foods, such as dairy products. Irritability upon discontinuing the consumption of a particular food and improved behavior after eating it may also indicate sensitivity. When this happens, you know that you should eliminate the problematic food. A food sensitivity test can be ordered to confirm the sensitivity. If positive, complete elimination of the food is advised. Additionally, supplementation with DPP-IV, gluten digest, or dairy digest enzymes (2 per meal) can be beneficial. 

Celiac Disease Consideration:

For older individuals with ADHD symptoms, it may be worth considering testing for celiac disease, an autoimmune condition triggered by gluten. If celiac disease is detected, a gluten-free diet should be followed to manage the condition effectively.

Understanding the differences between food sensitivities and food allergies is crucial for effectively managing symptoms and promoting overall well-being. While food allergies involve immediate reactions mediated by IgE antibodies, food sensitivities, including IgG and IgA reactions, manifest as delayed responses and can affect various body systems, particularly the gut.

In addition to the highly inflammatory foods like gluten, dairy, and soy that can trigger sensitivity reactions, it is important to note that some individuals may also experience adverse reactions to otherwise healthy foods due to gut impairment. This is where understanding the role of oxalates and salicylates becomes relevant.

Oxalates are naturally occurring substances found in many plant foods, such as spinach, beets, rhubarb, and nuts. While they are considered healthy, some individuals with compromised gut health may have difficulty properly metabolizing and eliminating oxalates. This can lead to the formation of oxalate crystals, which can contribute to inflammation. Tracking food intake and observing reactions, even up to a day later, can be helpful in identifying potential triggers. Elimination protocols, where specific foods high in oxalates are temporarily removed from the diet, should be implemented to assess improvements in symptoms.

Similarly, salicylates are natural compounds found in various fruits, vegetables, and herbs. They have anti-inflammatory properties and are present in foods like berries, citrus fruits, tomatoes, and spices. While salicylates are generally well-tolerated by most people, some individuals with sensitivities or compromised gut health may experience adverse reactions, such as digestive issues, skin rashes, or respiratory symptoms, when consuming foods high in salicylates. Tracking food consumption and associated symptoms can help identify potential salicylate triggers. Elimination diets or working with healthcare professionals who specialize in food sensitivity testing, such as Vibrant America’s Food Zoomer, can provide valuable insights into specific sensitivities and guide personalized dietary adjustments.

Clear observation and tracking of food intake, along with associated reactions, can be instrumental in identifying individual triggers and formulating appropriate elimination protocols. It is important to approach this process with patience, as it may take time to pinpoint specific food sensitivities and their effects on overall well-being.

It is worth noting that food sensitivities and intolerances can vary greatly among individuals, and what works for one person may not apply to another. 

Make the choice to be proactive about your child’s gut health as it will promote his overall well-being.
