Most teachers I know don't eat during the day.
They are so busy putting their students first, that they don't even drink an adequate amount of water during the teaching day, thereby ending the day and week feeling fatigued and tapped out. It's no wonder so many teachers retire with the highest incidence of post-career mortality. They have nothing else to live for.
It's very noble that one should place others before themselves, but nutrition is ultimately a very important element of holistic balance we ought not try to live without. How do we as teachers, keep our day fresh and filled with nutrition, while running a strongly organized classroom?
There is a healthy eating program that mostly gets circulated throughout the elementary school system. I was lucky enough to have this program offered to my students at the last middle school I attended. It was just wonderful because we all sat together and either ate fruit, or tasted the outcome of a recipe we all made together, and we discussed the nutritional goodness of the food we were eating. The students were always interested that I maintained a vegetarian lifestyle for 12 years. "Really Ms. Dunn, no carne asada? No pork chops or bacon?" those were the first questions from their lips. This would inspire a deeper conversation about health, not just the food we ate. This always made me feel that as a teacher, I was contributing to more than just their academic health, but their health as a whole.
Being the example of health is important. It is not enough to merely be book smart. It is more often that we pull ourselves out of balance because we feel our teaching curriculum and professional development classes and such should go first...but....if we are not well enough to complete the tasks required to be successful in each, how will we be able to continue educating these kids? We have to look at this piece and approach with patience and constancy.
