The Autoimmune Protocol (AIP) Diet: Foods, Benefits & Practical Tips

The Autoimmune Protocol (AIP) diet is an elimination-style dietary approach that some people use to identify foods that may contribute to digestive discomfort or inflammatory symptoms.

Based on principles similar to the Paleo diet, the AIP diet focuses on nutrient-dense whole foods while temporarily removing certain foods that may be problematic for some individuals.

While research into the AIP diet is still evolving, many people use it as a structured way to explore how different foods affect their wellbeing.

This guide explains:

  • What the AIP diet is

  • Foods included and excluded

  • Potential benefits

  • The role of gut health

  • Practical tips for getting started

What Is the AIP Diet?

The Autoimmune Protocol (AIP) diet is a temporary elimination diet designed to help individuals identify foods that may not agree with them.

The process generally involves:

Phase 1: Elimination

Removing specific foods for a period of time.

Phase 2: Reintroduction

Gradually reintroducing foods one at a time while monitoring symptoms and tolerance.

The goal is not necessarily long-term restriction, but rather gaining a better understanding of individual food responses.

Why Do People Follow the AIP Diet?

People may choose to explore the AIP diet for a variety of reasons, including:

  • Digestive discomfort

  • Food sensitivities

  • General wellbeing

  • Interest in anti-inflammatory eating patterns

Because every person responds differently to foods, the AIP diet attempts to create a structured framework for self-observation.
