They all contain food additives or chemicals that can be dangerous for children….In particular, the policy statement warns about:

• Bisphenols, such as BPA.
• Phthalates.

• Artificial food colors.
• Nitrates and nitrites.

Some food additives can cause reactions

• Digestive disorders – diarrhoea and colicky pains.
• Nervous disorders – hyperactivity, insomnia and irritability.
• Respiratory problems – asthma, rhinitis and sinusitis.
• Skin problems – hives, itching, rashes and swelling.

Some studies indicate that certain food colorings and preservatives may increase hyperactive behavior in some children.
