While still the smallest of the specialty diet categories, paleo eating is gaining traction with sales forecasted to reach $300 million by 2018, according to Nutrition Business Journal. This nutrition plan proposes that because humans evolved as hunter-gatherers who ate primarily nuts, seeds, fruit, vegetables and meat, our bodies are not prepared to digest many of the foods found in the modern diet. The solution? You guessed it: Dining only on foods our early ancestors would have recognized.

While most big CPG companies appear to be taking a wait-and-see approach before developing paleo-specific lines, smaller brands are jumping at the chance to attract the growing paleo audience with minimally processed, whole food-focused convenience products. Look for paleo answers for everything from trail mix to cereal, all made without grains and minimal, if any, sweeteners.
