What Are Food Sensitivities?

Food sensitivities occur when a person's immune system reacts to certain foods in a way that doesn't involve the immediate, life-threatening response typical of a food allergy. Instead, food sensitivities can lead to more delayed and less severe reactions. These reactions are often mediated by IgG antibodies, as opposed to the IgE antibodies involved in true food allergies.

The symptoms of food sensitivities can vary widely and include digestive issues like gas, bloating, diarrhea, or constipation; skin problems like rashes or eczema; joint pain or inflammation; headaches or migraines; fatigue, sleep disturbances; and mood changes like depression. Over time, constant exposure to foods that trigger sensitivities can lead to chronic inflammation in the body, which is linked to a variety of health problems, including increased risk for autoimmune diseases, metabolic disorders like obesity and diabetes, and cardiovascular diseases.

Therefore, identifying and addressing food sensitivities can be crucial for improving a person's overall health and well-being, particularly for individuals dealing with chronic conditions where inflammation plays a significant role. 

Top 10 Conditions and Symptoms Associated with Food Sensitivities

Food sensitivities can impact various aspects of health. Here are the top 10 conditions or symptoms often associated with food sensitivities:

1. Digestive Issues: 

This is a common manifestation of food sensitivities. Symptoms can include bloating, gas, diarrhea, constipation, and Irritable Bowel Syndrome (IBS). The discomfort typically arises hours or even days after consuming the offending food.

2. Skin Problems: 

Foods that don't agree with your system can lead to skin issues, like eczema, acne, and rashes. The skin can be a reflection of internal inflammation caused by sensitivities.

3. Fatigue: 

Consistently feeling tired or experiencing a lack of energy, even after a good night's sleep, can be linked to food sensitivities. This may be due to the body's effort to deal with the inflammation or imbalances caused by the offending food.

4. Mood Disorders: 

There's a growing understanding of the gut-brain connection. Food sensitivities can contribute to mood swings, anxiety, depression, and other mental health issues.

5. Joint Pain: 

Inflammation from food sensitivities can contribute to joint pain and swelling, resembling arthritic symptoms.

6. Headaches and Migraines: 

For some individuals, certain foods can trigger headaches or migraines. This reaction can occur due to inflammation or specific food chemicals.

7. Respiratory Issues: 

While less common, some people with food sensitivities experience respiratory symptoms like a runny nose, sinus congestion, or asthma.

8. Weight Fluctuations: 

Unexplained weight gain or difficulty losing weight may sometimes be linked to food sensitivities, as they can impact metabolism and gut health.

9. Brain Fog: 

Difficulty concentrating, memory problems, and a general feeling of mental cloudiness can be associated with food sensitivities, potentially due to inflammatory responses in the body.

10. Autoimmune Responses: 

Evidence suggests that chronic exposure to foods that trigger sensitivities may contribute to or exacerbate autoimmune conditions, where the body's immune system attacks its own tissues.

Advanced Functional Medicine Lab Tests For Food Sensitivities

Precision Point Diagnostics offers superior testing solutions for food sensitivities. Here are two popular testing options that practitioners run:

The P88 Dietary Antigen Test IgG/C3d

The P88 Dietary Antigen Test IgG/C3d is a notable advancement in the field of food sensitivity testing. It uniquely measures both IgG antibodies and complement C3d reactions, providing a detailed analysis of the body's immune response to 88 common foods. This dual-marker approach offers a more comprehensive assessment than tests that only measure IgG antibodies. Using an indirect ELISA method, it can detect immune complexes that include the complement marker C3d, a significant indicator of inflammation.​

The P88-DIY IgG/C3d (Micro-Sampling "Do It Yourself Collection")

The P88-DIY IgG/C3d (Micro-Sampling "Do It Yourself Collection") is the same test above, differing in that this version enables patients to collect samples at home using a micro-sampling device. It is designed for convenience, allowing for easy sample collection compared to traditional finger stick methods. Typically, finger sticks involve pricking the finger and collecting the blood on a card or piece of paper. However, this method often does not yield enough blood to run tests with many markers. The micro-sampling device used in the P88-DIY test overcomes this limitation by extracting sufficient blood to conduct the comprehensive analysis of IgG and C3d reactions to 88 foods​.

How Do The Test Results Inform Treatment Plans?

For patients with food sensitivities identified by testing, the treatment typically involves a structured approach. 

Dietary Interventions

Initially, an elimination diet is prescribed, requiring the patient to completely avoid foods identified as sensitivities for about 3-4 weeks. This phase, crucial for identifying specific triggers, is accompanied by detailed symptom monitoring to track any changes or improvements in the patient's condition. Following the elimination period, each food is gradually reintroduced individually, allowing for the observation of any adverse reactions. Any returning symptoms indicate that the particular food that was challenged should be avoided for an additional 3 to 6 months. Supportive care, including nutritional guidance, is provided throughout this process to ensure the patient maintains a balanced diet. This protocol requires careful planning and ongoing support from healthcare professionals.

Gut Healing Herbs and Supplements

For patients dealing with food sensitivities, certain herbs can be particularly beneficial in healing and soothing the gut.

Turmeric, specifically its active component curcumin, is renowned for its potent anti-inflammatory effects. These properties make turmeric an excellent choice for mitigating gut inflammation often associated with food sensitivities. By reducing inflammation, turmeric can help heal the gut lining, improving its function and potentially reducing sensitivity reactions.

The mucilage and polysaccharides in slippery elm form a protective coating on the gut lining. This coating action not only soothes irritated mucosa but also promotes healing in the digestive tract. This can be particularly helpful for those with food sensitivities, as it helps restore the integrity of the gut barrier, potentially reducing the likelihood of adverse reactions to foods.

Like slippery elm, marshmallow root is rich in mucilage, which soothes and protects the gastrointestinal lining. Improved gut health can lead to a decrease in the severity of food sensitivity symptoms.

Stress Reduction Techniques

Stress significantly impacts gut health, which is particularly relevant for those with food sensitivities. The stress-activated Hypothalamic-Pituitary-Adrenal (HPA) axis releases cortisol, affecting gastrointestinal functions like gastric emptying and increasing colonic contractions. Additionally, stress can increase intestinal permeability, allowing unwanted particles into the bloodstream, thus triggering inflammation. Managing stress is vital for those with food sensitivities as it may help reduce these gut-related issues and alleviate sensitivity symptoms. Helpful stress reduction techniques include meditation, yoga, and breathing techniques.

Food Sensitivity: Key Takeaways

If you are a practitioner treating chronic diseases, understanding food sensitivities and their impact on health is vital. Unlike immediate allergic reactions, they often involve delayed and less severe symptoms mediated by IgG antibodies. Key symptoms include digestive issues, skin problems, fatigue, mood disorders, and joint pain, which can lead to chronic inflammation and increase the chances of developing autoimmune and metabolic diseases. Functional medicine lab tests, like the P88 Dietary Antigen Test IgG/C3d, help identify specific food sensitivities. Treatment involves elimination diets and reintroduction phases, supplemented by gut-healing herbs like turmeric, slippery elm, and marshmallow root. Stress management is also emphasized due to its significant impact on gut health, highlighting techniques like meditation and yoga for those with food sensitivities.
