Sustainable food

I am currently up in Hood River Oregon where the valley is just glorious in all of the blossoms.  I am loving the conversations of all the fruit that is starting its growing process and keep asking when are these crops going to be ready to harvest?  You might notice I can't wait.

There are so many aspects to sustainable food and for this post I wanted to think about how much I really need to stay alive, thus sustain my existence.  And couple this will how much food I want to eat.  I could eat and do eat a lot more than I need to stay alive.
The balance of calories is a micro example of a sustainable system.
First you have to determine how many calories you need.  There are all kinds of website that can help determine this.  It gets a bit complicated when you factor in your exercise and lifestyle.  But the average person needs about 2000 calories a day.  So if you break down your meals into 3 a day that is about 667 per meal.  And some of us eat snacks, so move some calories over to snacks and take them away from meals.

Well we all can attest to not eating enough, or eating too much and finding that balance.  Maybe you eat too many calories at one time because you know you are going to be with less at another time and you are planning.  Also what happens when the calories we need are not available - pretend you can't just go to the grocery store and buy apples from around the world?

This has been a neat exercise for me, because it made me think how much I rely on connivence and what kind of changes I would have to make to plan out my food in take and caloric burning if food was limited.  Ultimately this is the kind of level of detail we should know to truly incorporate sustainability into our daily living...
