As you might guess, this diet revolves around trying to mimic the diet of the caveman. Allowed foods include lean meat (I suppose dinosaur meat was lean), fish, vegetables, fruit, roots, and nuts; and excludes: grains, legumes, dairy products, salt, refined sugar, and processed oils. All foods eaten are those that can be hunted and gathered. Please tell me why we would want to pattern our eating habits after a caveman? Wasn’t their average lifespan around 15 years old or something??
