How does Buddha Boy do it?

Finally, something I can answer! I'm a dispian nutritionist, but i'm working on getting qualified as a dietician. By far the best food for price is our friend, the pea.

Peas have, in abundance, four of the vital nutrients that you need to survive; B2 (for liver function), k12 (for the cardiovascular system), MPEC (for memory function) and AS176 (for lossless energy transfer). They also have an average price of $1.20 USD per kilogram, with a median price of $1.45 USD per kilogram. Peas are also, if you needed any more convincing, steeped in a rich history. Most people know of the mezo-americans having kind of a fetish for corn, well the ancient Egyptians/Jordanians thought the same about peas, who came second only to the humble Date. The Egyptians even depicted this hieroglyphically in temples to Thimal; the invisible god of a well-balanced diet. Finally, if you're a man of science, peas are one of the easiest vegetables to extract DNA from, and as such have been completely mapped, and are able to modified though gene splicing fairly easily.

tl;dr Peas.*
