It is a carefully designed mixture of whole grains (such as oats, wheat, barley or corn) to which dehydrated fruits and/or nuts are added, which can be eaten with milk, yoghurt or honey. The basis of a correct diet is whole grains together with fruits and vegetables. If we add to this that breakfast should be one of the main meals of the day, muesli is one of the best options, because in the main meal we would give the body the main nutrients it needs. It is a food rich in essential nutrients such as carbohydrates, proteins, vitamins and lipids. By using whole grains the body assimilates sugars slowly, helping us to maintain energy throughout the morning. Its high fibre content helps to maintain a good intestinal transit, as well as to increase satiety and reduce appetite. It is also a good food in terms of protein intake, as well as for its high vitamin value, as it is a source of B vitamins.
