The meddlesome, cancerous lump also presents a counterpoint to supporters of the paleo diet. The paleo diet simulates what our hunter-gatherer ancestors might have eaten before the invention of organized agricultural systems. It focuses on increasing the amount of protein, fiber, potassium, vitamins and healthy fats, while cutting back on carbohydrates and removing all processed sugars and chemicals. The permissible food groups comprise grass-produced meats, seafood, fresh fruits and veggies, eggs, nuts and seeds and healthful oils. However, this healthful eating regimen comes at a high cost to many food lovers. Dairy, potatoes, salt, and cereal grains are just a few of the items paleo dieters aren’t allowed to savor.
