A new study conducted by researchers at American Academy of Pediatrics reveals that newborn infants are being fed solid foods earlier than recommended, putting them at serious risk of chronic diseases.

While it is recommended that babies should be on a liquid diet at least until they turn four months old, researchers found that two in five mothers are giving their babies solid foods before they are four months of age, increasing the risks of allergies and food sensitivities.

The researchers conducted the study, titled Prevalence and Reasons for Introducing Infants Early to Solid Foods: Variations by Milk Feeding Type, in more than 1,300 mothers in the US. The study has been published in the journal Pediatrics.
