Baby foods 'lack nutrients', warn Scottish researchers
Baby foods made by firms including Cow and Gate, Heinz and Ella’s Kitchen have far fewer nutrients than homemade meals, according to a new study.
Many contain high levels of sugar and some are promoted for use from four months of age - a time when babies should still be on a diet of breast or formula milk.
Babies would need to eat twice as much shop-bought food to get the same energy and protein as meals cooked at home, researchers found.
The study, from the department of human nutrition at the University of Glasgow, said many weaning foods “would not serve the intended purpose” of giving a baby extra nutrients or a range of tastes and textures.
Current guidelines encourage weaning from six months of age, with babies fed only breast or formula milk before this time.
But some parents choose to wean early and baby foods are often marked as “suitable from four months”.
Experts analysed all the baby foods produced by the main UK manufacturers. These were Cow and Gate, Heinz, Boots, Hipp Organic, Ella’s Kitchen and Organix.
Products included ready-made soft foods and dry foods such as cereal that could be made up with milk or water, biscuits, rusks, bars, snacks and cakes.
Nutritional information for each product - such as calories, fat, iron and calcium - were collected from manufacturers’ websites, the products themselves and from email enquiries.
Of the 479 items, 364 (79%) were ready-made spoonable foods and 201 (44%) were aimed at infants from four months. Some 65% of the products were sweet foods.
The researchers said the typical calorie content of the spoonable foods was 282 kJ per 100g, almost identical to breast milk at 283 kJ per 100g.
But purees and spoonable foods made at home were “more nutrient dense” than the shop-bought foods. Examples of homemade foods included chicken stew, beef with mash, stewed apple with custard and apple with rice pudding.
And while commercial finger foods contained more calories, they had a “very high” sugar content.
The iron content of most of the foods was also lower than that found in formula.
Writing in the journal Archives of Disease in Childhood, the researchers said: The UK infant food market mainly supplies sweet, soft, spoonable foods targeted from age four months.
“Most products are ready-made spoonable foods that are no more energy dense than formula milk, and are generally much less nutrient dense than homemade foods.
“This meant that around 50g of a soft spoonable family food might supply the same amount of energy and protein as 100g of ready-made spoonable food.”
The Department of Health recommends a gradual transition to solids starting with cereals, vegetables and fruits, before moving on to proteins.
It recommends babies still continue to receive breast milk or a pint of formula a day while they are being weaned, up to their first birthday.
The experts said many shop-bought foods are sweet, possibly to cater for babies’ inherent preference for sweet foods.
“However, repeated exposure to foods during infancy promotes acceptance and preferences.”
While shop-bought foods use fruit sugars to sweeten foods rather than added sugars, both probably contribute to tooth decay in equal measure, the experts added.
