Best sustainable food for maximum energy?

[Crazymacc]

I am doing a project to see whether we can make my school sustainable and I was wondering what would be the best food to grow for maximum energy?

pretty sure "most efficient foods" goes to insects and algae. Not exacting appealing, but very high in nutrients with very little input.

I like To have a cup of Coffee and a nut butter and Jelly sandwich on whole grain in the AM, and in the PM usually something like a Salad, Beans, Fruit, etc. in the PM. Ofcourse a lot of Water/Fruit juice throughout the day.

To make it sustainable, you just don't want to grow the "most efficient" food, because you need variety to have a healthy diet.

 

So that means:

Greens - lettuce and other veggies, carrots, brocoli, etc.

Starches - potatoes and/or rice

Grains - wheat most likely, then used to make bread

Fruits - Probably Apples - if you have a Greenhouse, you can grow just about anything, so I would add Oranges and berries (Strawberries, blueberries, etc)

Protein - this is where it gets tricky. You've got beans and nuts, but ideally, actual real meat is going to be best

 

So how much of that is practical to actually grow for a school? Probably not the Grains or any animals. Takes up too much space. You'd need a literal crop field.

 

However, having a diverse and well rounded Greenhouse Garden will be suitable to grow most of the rest of stuff. You can even have some fruit trees in the greenhouse as well. I would just stay away from exotic foods, especially those that require unusual or extremely specific growing conditions.

I'm going to guess potatoes in terms of cheapness, efficiency, and energy.
