Good for your daughter leodis!!This 100% and sugar is the biggest contributor. One of my kids was having a lot of challenges last year and we just eliminated sugar and she is a brand new kid. 99% of the issues she was dealing with went away. It's pretty crazy actually what diet does.
The problem with the medical community is they DON'T want to cure anything that can lead to a lifetime of dependency on a drug(s). That's why I always applaud anyone who has found a non-prescription/all-natural way of eliminating any health/behavioral issues.
My son and his young boys consume raw milk, it is so fantastic for the immune system. You won't find any sugar in his house either. I have a moderate sweet tooth, no candy, sweets, etc, but I really like raw honey as a sweetener.
