1. Supports Gut Healing and Reduces Inflammation
The Paleo diet eliminates common gut irritants like grains, dairy, and processed foods that can cause inflammation and disrupt the gut lining. By eating whole, nutrient-dense foods, it helps soothe the digestive tract and promote healing.
2. Rich in Gut-Friendly Nutrients
Foods like bone broth, fermented vegetables, and omega-3 rich fish provide collagen, gelatin, and healthy fats that support gut lining integrity and reduce intestinal permeability (leaky gut).
3. Avoids Potentially Harmful Lectins and Gluten
Grains and legumes contain lectins and gluten, which can trigger immune responses and worsen symptoms in people with autoimmune diseases or gut sensitivities. Paleo’s exclusion of these foods helps reduce this immune activation.
4. Promotes a Healthy Microbiome
By emphasizing fermented foods (like sauerkraut, kimchi, and kombucha) and fiber-rich vegetables, Paleo helps nourish beneficial gut bacteria, improving digestion and immune function.
5. May Improve Symptoms of Autoimmune Diseases
Many people with autoimmune conditions report reduced symptoms—like joint pain, fatigue, and skin issues—when following a Paleo or autoimmune-specific Paleo diet (AIP), due to decreased inflammation and immune system regulation.
6. Eliminates Processed Sugars and Additives
Cutting out refined sugars and artificial additives reduces the growth of harmful bacteria and yeast in the gut, supporting better digestion and balanced immunity.
