Babies fed taster portions of the new Nordic diet of fruit, berries, roots, and vegetables, as well as breast or formula milk, from the age of 4-6 months of age, were eating almost double the number of vegetables (46% more), than those fed a conventional diet, by 18 months of age.
Researchers from , Stockholm County Council Centre for Epidemiology, and the University of California, USA, followed two groups of babies from 4-6 months through to 18 months, as part of the OTIS trial (see editor's notes below). A total of 250 babies took part and 82% completed the trial.
The study found marked differences in the dietary habits of the toddlers in the 2 groups. Those on the new Nordic diet, who had been supplied with Nordic home-made baby food recipes, protein-reduced baby food products, and offered parental support via social media, consumed 42-45% more fruit and vegetables at 12-18 months of age, compared to those who were fed the conventional diet currently recommended by the Swedish Food Agency.
While fruit consumption within the conventional group remained consistent, babies fed the conventional diet reduced their vegetable intake by 36% between 12-18 months.
Babies on the Nordic diet had an average protein intake 17-29% lower than those on the conventional diet at 12-18 months of age. This was still within recommended protein intake levels and the overall calorie count between the two groups was the same. The protein reduction in the Nordic diet group was replaced by more carbohydrates from vegetables, not more cereals, together with some extra fat from rapeseed oil.
Lead researcher Dr Ulrica Johansson, a Medicine Doctor in pediatrics and registered dietitian at the University of Umeå, Sweden, said there did not appear to be any negative effects from having a lower protein intake.
