A test of 479 shop-bought products from leading manufacturers of baby foods sold in the UK were found to be deficient in nutrients that is needed to meet infants' dietary weaning needs

During the tests, researchers found that 50% of the products were classified as sweet. It is advisable to avoid sweet foods during weaning time for sugar can encourage sweet tooth and tooth decay.
"People might think that something sweetened with fruit is healthier, but it's not. Young babies like sweet food because it tastes like breast milk but it is not moving them on. It is processed food that's been put in a jar so it's not that surprising that it does not match up with home-cooked foods."
It is advisable for parents to get advice from a healthcare professional when they plan to begin weaning.
