I read the last two newsletters on your website and was amazed with the information. I am just starting to look at food additives/preservatives as our 6 year old son has difficult behaviours at times. We are vegetarian and eat a healthy diet but we have noticed these behaviours increasing since starting school...he is restless, has difficulty concentrating, can be anti-social and unable to share, aggressive (punching himself) and teary...however, this is not all the time...he can be calm, delightful and co-operative one day and then highly emotional the next. Specialists have no answers for us re the cause but after him having his first Redskin a few weeks ago and some Arnotts Family assorted cream biscuits (another first) he just went crazy and was angry and aggressive for the following 3 hours. - email
