The paleo diet is a nutritional plan that focuses on eating foods similar to those consumed by our ancient ancestors during the Paleolithic era. This diet emphasizes whole, unprocessed foods such as lean meats, fish, fruits, vegetables, nuts, and seeds, while avoiding processed foods, grains, legumes, and dairy products. Proponents of the paleo diet believe that modern diets contribute to various health issues, and that returning to a more natural way of eating can improve overall health. The diet encourages individuals to prioritize nutrient-dense foods and maintain a lifestyle that mimics the eating habits of early humans.
