Muesli is a blend of oatmeal and other cereals (grains), dried fruits, and nuts, eaten with or without milk at breakfast. The term muesli originated in Switzerland, but similar mixtures of cereals, fruits, and nuts were eaten in other European countries under different names. There really is no difference between "muesli" and "Swiss muesli" - it is simply a marketing strategy. The Swiss are portrayed in the media as healthy, outdoorsy folk with an inordinate fondness for cheese fondues, a mania for cleanliness and order, and an odd fixation with yodelling. Labelling a muesli product as "Swiss" would seem to imply that the recipe originated in Switzerland. This may not be the case. The final proof of the matter is in the nutritional information printed on the side of the package. There is nothing inherently better or more nutricious about "Swiss" muesli compared to other mueslis and muesli-like products. The advertisers are trying to form a linkage in your mind between the image of the youthful, healthy, and outdoor-loving Swiss and a product that might have helped them achieve this sparkling vitality and good health. Read the labels and make your decision to buy based on nutritional information alone.
