Often perceived as the best option, home cooked meals are cheaper but they usually exceed energy density and dietary fat recommendations, researchers said.
It is recommended that the introduction of solid foods, known as weaning, begins when a child is six months old. It should include a variety of foods to provide a balanced diet rich in a broad range of nutrients.
The researchers from University of Aberdeen and University of Warwick in the UK wanted to assess how well homemade and commercially available readymade meals designed for infants and young children met age specific dietary recommendations.
In terms of the food group content, 16 per cent of the home cooked meals were poultry based compared with 27 per cent of the readymade meals; around one in five (19 per cent) were seafood based vs 7 per cent of the readymade meals; a similar proportion (21 per cent) were meat based compared with 35 per cent of the commercial products; and almost half (44 per cent) were vegetable based compared with around a third (31 per cent) of the readymade meals.

Home cooked meals also provided 26 per cent more energy and 44 per cent more protein and total fat, including saturated fat, than commercial products.
While almost two thirds (65 per cent) of commercial products met dietary recommendations on energy density, only just over a third of home cooked meals did so, and over half (52 per cent) exceeded the maximum range.
"Dietary fats contribute essential fatty acids and fat soluble vitamins together with energy and sensory qualities, thus are vital for the growing child, however excessive intakes may impact on childhood obesity and health," researchers said.
Parents may choose to vary the content of recipes, and there are likely to be natural variations in the nutritional content of raw ingredients, thus making direct comparisons harder to make, researchers said.
The research was published in the Archives of Disease in Childhood.
