The health of our children is as important as our own. Last summer, I wrote: Is it the Food? Or is it Something Else? https://songdove.fa-ct.com/wordpress-mu/tame/is-it-the-food-or-is-it-something-else/ in an effort to ensure my own circles understand that childhood behaviour has multiple potential causes and not to just look at one. While that article talked about the need to uncover any food that could be causing undesirable behaviour, the flip side is ensuring food is included in the diet that encourages beneficial behaviour. For many years I have felt that what kids are fed has a direct impact on various kinds of behaviour from hyperactivity (ie: red food dye and sugar), to lethargy (ie: lack of vit B and too much sugar), to always being sniffly and whiny (ie: lack of vit C), etc. I ran across this article from 1971 saying similar things. The authors of this article used very high amounts of the vitamins and minerals in question, which reminded me of how for many years, my sister always seemed deficient in Vitamin C. She would take 1000mg tablets three to four times per day to stay on top of it and never hit saturation (the point where you get a soft stool or the runs). If she didn't do this, she'd suffer the consequences very quickly. I haven't asked if she still does this, but considering she has her family on Camu Camu powder, I'd say it continues to be a concern to have enough Vitamin C in her system. High levels are required for her. In the same way, this article's authors found that Vitamin C, some of the B vitamins, and other nutrients also needed to be high for various children affected by learning disabilities, brain damage, etc. The article is 11 pages long, and spends a few pages in the middle talking exclusively about childhood Schizophrenia, but before those pages and after them, there is a fair bit of useful discussion around nutrition and it's benefit to the growing brain of a child. Incidentally, brain damage can happen at any point in a child's growing years, so the tidbits of knowledge offered here, can be a useful jump-off point for others who may be looking for ways to make positive changes in a child's apparent behaviour. http://orthomolecular.org/library/jom/1971/pdf/1971-v03n02-p095.pdf
