Baby foods made with rice are showing signs of arsenic poisoning which can affect the neurological and muscular systems. It is better for parents to make homemade baby foods using cereals instead of ready-made packaged baby foods, especially for children up to 3 years old, as packaged foods contain preservatives that can harm babies from 3 months to 1 year old. For more information, parents can contact Satya Kovur, a wellness consultant.
