The Life-Altering Effects of Food Sensitivities

Updated: Nov 12, 2023


Our lives are busy, and it's common to overlook the impact our food choices can have on our overall well-being. However, understanding the relationship between food sensitivities, gut health, and metabolic function is crucial for maintaining optimal health. In this article, we will delve into the science behind IgG food sensitivities, the concept of "leaky gut," and how they are interconnected with various diseases and health conditions. We will also explore how naturopathic integrative, functional medicine methods can support gut and metabolic health, ultimately leading to a healthier and more balanced life.

IgG Food Sensitivities: Unveiling the Science

Food sensitivities occur when the body's immune system reacts adversely to certain foods. Unlike immediate allergic reactions, which are mediated by IgE antibodies and can be severe and life threatening, food sensitivities involve a delayed immune response mediated by IgG antibodies. These IgG reactions can manifest in a wide range of symptoms, including digestive issues, skin problems, fatigue, and mood disturbances and can occur up to 72 hours after you’ve consumed triggering foods.

Leaky Gut: The Gateway to Systemic Inflammation

Leaky gut, or increased intestinal permeability, is a condition where the lining of the digestive tract becomes compromised due to chronic irritation and inflammation, allowing harmful substances, such as partially digested food particles and toxins, to leak into the bloodstream. Chronic consumption of foods an individual is sensitized to can contribute to the development of leaky gut syndrome.

Leaky gut triggers an immune response in the body, releasing inflammatory molecules that circulate throughout the whole body creating systemic inflammation. This immune response can also cause the body to be on constant high alert, leading to a cascade of hormonal imbalances and chronic stress. These imbalances further contribute to inflammation and, if allowed to continue, can pave the way for the development of numerous chronic diseases and health conditions. (This is why I tell patients that no one system in our body acts alone and that we need to treat the whole person to treat the cause.)

The Link to Prevalent Diseases and Health Conditions

The impact of leaky gut syndrome goes beyond digestive issues. Research suggests that it may contribute to the development of various conditions, including:

  • Autoimmune Disorders: Leaky gut can initiate or exacerbate autoimmune conditions, as the immune system mistakenly attacks healthy tissues due to the increased presence of foreign substances in the bloodstream.

  • Metabolic Disorders: Insulin resistance, obesity, type 2 diabetes, and dyslipidemia have all been linked to chronic low-grade inflammation caused by leaky gut.

  • Neurological Disorders: The gut-brain connection suggests that inflammation originating in the gut can trigger neuroinflammation. Studies have indicated that leaky gut may play a role in neurological conditions such as ADHD, Alzheimer's Disease, Parkinson's Disease, and Multiple Sclerosis.

  • Mood Disorders: Inflammation caused by leaky gut can negatively impact brain function and neurotransmitter production, contributing to anxiety, depression, and other mood disorders.

Supporting Metabolic Health Naturally

Recognizing the importance of addressing food sensitivities and leaky gut, it's important to explore naturopathic and integrative functional medicine methods to address the cause. Some effective strategies include:

  • Elimination Diet: Identifying and temporarily removing the trigger foods from your diet can help heal the gut lining and reduce inflammation. Working with a qualified health practitioner can simplify this process. An elimination diet can be as simple as taking out the 8 most common allergens or going down to a 4 foods diet and adding back in foods over weeks and months. Many people find the use of Functional Lab testing such as IgG Food Sensitivity Testing helpful in shortening this elimination process and jump starting the gut healing process.

  • Nutrient-Dense Diet: Emphasizing whole, unprocessed foods rich in antioxidants, vitamins, and minerals can provide the necessary building blocks for gut repair and support overall well-being.

  • Probiotics and Prebiotics: Introducing beneficial bacteria through probiotics and nourishing them with prebiotic fibers can restore a healthy balance of gut microbiota, promoting gut health and reducing inflammation.

  • Stress Management: Chronic stress can wreak havoc on gut health and hormone balance. Implementing stress management techniques such as meditation, yoga, and mindful practices can lower the body’s inflammation and have a positive impact on overall gut and metabolic health.
