Food Allergies & Sensitivities

The diet eliminates common allergens and focuses on whole, single-source proteins and limited ingredients, which can help identify and manage food sensitivities. The careful selection of ingredients reduces the risk of allergic reactions and supports digestive health.

How By using limited, whole food ingredients and avoiding common allergens, the diet helps reduce immune system reactivity. The single-source proteins and careful ingredient selection allow for easier identification of potential allergens and support the dog's immune tolerance.

Key foods Lean chicken, turkey, fish, sweet potato, brown rice, pumpkin

The Low-FODMAP diet helps identify and manage food intolerances and sensitivities, particularly to lactose, fructose, and fructans, which are common but often undiagnosed causes of digestive distress. The structured elimination and reintroduction phases allow individuals to pinpoint specific carbohydrate intolerances and determine personal tolerance thresholds. This personalized approach prevents unnecessary broad food restrictions while identifying true problematic foods.

How Many food sensitivities involve malabsorption of specific carbohydrates due to enzyme deficiencies (like lactase) or transporter limitations (like fructose transporters). The systematic elimination phase removes all high-FODMAP foods, allowing symptoms to resolve, while the structured reintroduction phase tests individual FODMAP groups to identify specific intolerances. This reveals whether symptoms are due to lactose malabsorption, fructose malabsorption, or sensitivity to specific oligosaccharides or polyols.

Key foods Lactose-free dairy alternatives, gluten-free grains like rice and quinoa, low-fructose fruits like strawberries and oranges, well-tolerated vegetables like carrots and bell peppers, eggs and unprocessed meats, firm tofu, garlic-infused oil instead of garlic cloves

The Macrobiotic Diet naturally eliminates many common allergens and sensitivity triggers including dairy, eggs, and when properly implemented, can avoid gluten by emphasizing rice, millet, and quinoa over wheat and barley. The diet's elimination of nightshades removes triggers for individuals sensitive to these foods, while the absence of processed ingredients removes artificial additives and preservatives that cause reactions. The emphasis on whole, simple foods and traditional preparation methods makes it easier to identify and avoid individual triggers.

How By eliminating common allergens (dairy, eggs) and potential triggers (nightshades, processed additives), the diet reduces immune system activation and histamine responses that cause sensitivity symptoms. The emphasis on gut-healing foods like fermented products and fiber supports intestinal barrier integrity, reducing the likelihood of food proteins crossing into the bloodstream where they can trigger immune reactions.

Key foods Brown rice, millet, quinoa, sea vegetables (nori, wakame, kombu), non-nightshade vegetables (leafy greens, root vegetables, cruciferous vegetables), adzuki beans, lentils, fermented foods (miso, tempeh)

SCD eliminates many common food allergens and irritants including gluten, lactose, soy, and processed additives, making it beneficial for those with multiple food sensitivities. By healing the gut lining and reducing inflammation, the diet may improve tolerance to foods over time. The elimination of complex carbohydrates that feed harmful bacteria also reduces the production of histamine and other inflammatory compounds that exacerbate food sensitivities.

How The diet's healing effect on intestinal permeability prevents larger food proteins from crossing the gut barrier and triggering immune responses. By eliminating processed foods with multiple ingredients and additives, SCD reduces exposure to hidden allergens and inflammatory compounds. The simplified, whole-food approach allows the immune system to calm down while the gut heals, potentially reducing reactivity to foods.

Key foods Single-ingredient whole foods like fresh meats, eggs, non-starchy vegetables, tree nuts (if tolerated), aged hard cheeses, fresh fruits, homemade yogurt fermented 24 hours, honey

The Raw Food Diet eliminates many common food allergens and sensitivities by removing processed foods, dairy, and gluten-containing grains in their conventional forms. The emphasis on whole, unprocessed foods reduces exposure to additives, preservatives, and inflammatory compounds. However, raw nuts and certain raw vegetables can still trigger sensitivities in some individuals.

How The elimination of processed foods removes common additives, preservatives, and modified proteins that can trigger immune responses. Sprouting and fermenting processes can reduce anti-nutrients and break down complex proteins, potentially making foods more digestible and less likely to cause reactions in sensitive individuals.

Key foods Raw fruits, raw vegetables, sprouted quinoa, raw coconut, raw seeds, fermented vegetables, raw herbs, cold-pressed oils

AIP diet is an elimination protocol that helps identify and manage food sensitivities by removing common inflammatory and allergenic foods. It provides a systematic approach to understanding individual food triggers.

How By systematically removing potential trigger foods and then carefully reintroducing them, the diet helps individuals identify specific food sensitivities while providing a nutrient-dense, anti-inflammatory dietary approach.

Key foods Grass-fed meats, wild-caught fish, coconut oil, fermented vegetables, bone broth, leafy green vegetables, turmeric

The Carnivore Diet serves as the ultimate elimination diet by removing all common food allergens and sensitivities except for animal proteins and dairy (if included). The diet eliminates the top plant-based triggers including gluten, soy, nuts, seeds, and nightshades, making it highly effective for identifying and managing food sensitivities. Most animal proteins are well-tolerated, and the diet can be further simplified to just beef and salt for those with severe multiple food sensitivities.

How By restricting the diet to animal-based foods, the diet removes lectins, saponins, gluten, and other plant proteins that commonly trigger immune responses and intestinal permeability. The simplicity of the diet allows the gut lining to heal from chronic exposure to irritants, reducing systemic immune activation. The highly bioavailable nutrients support immune system regulation and gut barrier integrity, further reducing sensitivity reactions.

Key foods Grass-fed beef, lamb, wild-caught fish like salmon and cod, pasture-raised eggs, pork, chicken, beef bone broth, ghee (if dairy is tolerated)

The Elimination Diet is the gold standard diagnostic tool for identifying food sensitivities and intolerances. By systematically removing the most common allergenic and inflammatory foods for 3-6 weeks, it allows the immune system to calm down and the gut to heal. When foods are reintroduced one at a time, reactions become clearly identifiable, enabling precise identification of problematic foods.

How Removing common allergens and inflammatory triggers allows IgG and IgE antibody levels to decrease and intestinal permeability to normalize. The gut lining repairs itself in the absence of irritating proteins, reducing systemic inflammation and immune activation. Upon reintroduction, specific immune reactions to problem foods become evident through symptoms like digestive distress, skin reactions, or fatigue.

Key foods Sweet potatoes, quinoa, wild-caught salmon, leafy greens like kale and spinach, blueberries, carrots, olive oil, lentils

A gluten-free diet directly addresses gluten-related food sensitivities and wheat allergies, eliminating a major category of food triggers that cause adverse reactions. This diet is essential for managing these specific sensitivities and often serves as a foundation for identifying other food intolerances through elimination protocols. By removing gluten-containing grains and focusing on whole, unprocessed foods, the diet reduces exposure to common allergens and additives found in processed wheat products.

How The diet eliminates gluten proteins and wheat components that trigger immune-mediated (allergic) or non-immune-mediated (sensitivity) adverse reactions, preventing the release of inflammatory mediators and reducing gut inflammation. By emphasizing whole, naturally gluten-free foods, the diet also minimizes exposure to additives, preservatives, and cross-reactive proteins found in processed foods, allowing the immune system and gut to stabilize.

Key foods Single-ingredient whole foods like fresh meats, fish, eggs, fruits, vegetables, rice, quinoa, legumes, nuts (if tolerated), seeds

The Paleo Diet eliminates the most common food allergens and sensitivities including gluten, dairy, soy, and peanuts, making it highly effective for those with multiple food intolerances. By focusing on whole, unprocessed foods and eliminating grains and legumes, the diet removes many compounds that trigger adverse reactions in sensitive individuals. Many people experience resolution of chronic symptoms like headaches, skin issues, and digestive problems when these triggers are removed.

How The diet eliminates gluten and other grain proteins that can trigger immune responses and increase intestinal permeability in sensitive individuals. Removal of dairy eliminates casein and whey proteins that are common allergens, while elimination of legumes removes lectins and other anti-nutrients that may cause digestive distress. The focus on whole foods reduces exposure to food additives, preservatives, and artificial ingredients that can trigger sensitivities or pseudo-allergic reactions.

Key foods Wild-caught fish, grass-fed meats, pastured eggs, sweet potatoes, leafy greens, cruciferous vegetables, berries, tree nuts like almonds and cashews (if tolerated)

Whole30 is specifically designed as an elimination diet to identify food sensitivities by removing the most common trigger foods for 30 days, then systematically reintroducing them. This protocol eliminates gluten, dairy, soy, legumes, and other common allergens and inflammatory foods, allowing the body to reset and symptoms to clear. The structured reintroduction phase enables individuals to pinpoint exactly which foods cause adverse reactions, making it one of the most effective dietary protocols for identifying food sensitivities.

How The 30-day elimination period allows antibodies and inflammatory markers associated with food sensitivities to decrease, giving the immune system time to calm down and the gut lining time to heal. When foods are systematically reintroduced one at a time, any immune or inflammatory response becomes clearly identifiable through symptom recurrence, allowing individuals to create a personalized diet that avoids their specific trigger foods while maintaining nutritional adequacy.

Key foods Grass-fed beef and lamb, wild-caught fish and shellfish, pastured eggs, variety of vegetables including nightshades and non-nightshades, fruits like apples and pears, compliant nuts like almonds and cashews, seeds like sunflower and pumpkin seeds, coconut products
