With the appearance of fast-foods, frozen semi-finished goods our nutrition turned to the strength test of our organisms. Often, when you are in a lack of time, you buy some sandwiches or burgers, because they are tasty, nourishing and rather cheap. Of course, you now that is fat and totally unhealthy, but you still buy it again and again. There is no doubt that you could by some fruit or vegetables, mineral water and some wholegrain bread and it would be a standard of healthy nutrition. But cellulose, which mostly constitutes fruit and vegetables that is digested in organism rapidly, will not give a feeling of satiety.
