They both had their points but failed to see where they are in agreement. Literacy and good food work well together. Really well. Kids, and anyone for that matter, think and learn much better when well fed. It seems ridiculously self evident that good food optimizes learning and behavior. Having a 6 year old reminds me of this every day. It would be a whole lot easier to give her 'regular' food but we would pay for it in increased irritability, tantrums, meltdowns not to mention sick days and doctor visits. So imagine what a classroom of well-nourished children could look like and what that classroom looks like today in every classroom in the country.
This is one of the great lesssons from Google. When Google was just a struggling company of 50 or so people, they hired a chef. Not just any chef, but a whole-real-organic-food lovin' guy to feed everyone in the company for free!
Bottom line: Good food is good brain fuel.
