So what single food can keep human being longest alive?
I think Gerben offered good advice for a vegan. I was one for 8 years (now I eat dairy a couple of times a week). I managed to stay very healthy by eating fruits, veggies, and combining incomplete proteins (beans/legumes plus grains).
In terms of a single food, which I don't think is a good idea (especially for a young person), I remember Georges Osawa (author of Zen Macrobiotics) a couple of decades ago claimed he lived on nothing but brown rice.
I've thought about this too, and if I had to choose just one food it would be types of
sprouted bread that I eat every day. Do you know about this? There is a company called "Food for Life" who makes several varieties. Their first product years ago they called "Ezekiel Bread" because the recipe can be found in the book of Ezekiel in the OT. It is bread made, not from flour, but from sprouting grains and beans, mashing them, creating a dough-like batter, adding yeast, and then baking it. It comes out looking very close to what flour bread looks like (there is another way to make it so it comes out more moist), but there are differences and major benefits to health and digestion.
For one, their Ezekiel recipe is a complete protein because they sprout both beans and grains (of course they are high in carbs too, but it's good carbs because they are "complex," and so break down much more slowly than refined carbs); I don't have a loaf in the house now, but if I remember correctly one slice is 7 grams of protein! I think their Sesame loaf is the same. I like the cinnamon raisen myself, which has only 4 grams per slice, but is great toasted with a little cold pressed oil brushed on.
Another benefit is how easy 100% sprouted bread is digested. You will never feel your energy sag from eating this bread (it digests MUCH easier than sticky flour bread, even whole grain varieties),and it zips thru the intestines giving one a nice cleaning. I actually do live on it during the day, except I eat fruit first thing in the morn, put oil on the bread (which I always toast), I take brewers yeast daily (great stuff); at night I usually have veggies and some grain, usually rice. Weekends I tend to party food-wise and eat cheese dishes (mmmmm, love pizza) and fine grain drinks (otherwise known as beer

).
