 The quality and quantity of diet has changed dramatically over the last fifty years. Of which, carbohydrates have the most significant changes; from unprocessed fruits and vegetables based carbohydrates to more processed cereal based ones Cordain et al. 2005. Epidemiological studies have shown that, as a result, ancestral diets had greater amounts of Non-Digestible Carbohydrates NDC than modern diets 100gday compared to 15gday with the inclusion of more indigestible intact cell wall plant material, such as tubers, grasses and sedges Eaton 2006. A strong association has been established between increased weight gain with decreased NDC intake Liu et al. 2003. Furthermore, increasing intake of NDC have shown to induce satiety and improve body composition in animals So et al. 2007 and humans Bouché et al. 2002.
