Because of the high frequency of nursing mothers there is concensus that, in general, the diet of Norwegian newborns is good for the first six months of life. However, several publications have questioned the recommendations concerning the babies' diet from the age of six to 12 months with respect to time of weaning and introduction of cow's milk, and intake of energy, fat-soluble vitamins, iron and essential fatty acids. The Norwegian National Nutrition Council has therefore evaluated the available data, and has adjusted some of the recommendations, including the recommendations for energy intake, energy percent from fat and essential polyunsaturated fatty acids.
