Good article with lots of useful information!
I scoured the list and found two that I consume nearly everyday.
One is a hot cup of green tea in the morning and a glass of lemon(squeezed lemon in water) in the afternoon. Never go wrong with them, for my daily dose of Vitamin C.
Cool, but keep in mind that tea on the spreadsheet is of the artificially fortified nature. The grey items are just there as filler, or sometimes as unrealistic alternatives (like many native American foods). Lemon on the other hand is great of course :-)
