Dont listen to these nerds. Humans are inherently born with the ability to photosynthesise, we evolved from triassic cordiceps fungi so its literally in our dna as a member of the chordata species (matthew 1:69). All u have to do is stare unflinchingly at a source of UV (uni-visual) light like the sun or the moon for an extended amount of time, and ur liver biochemically produces glucose for your endocrine (digestive) system.
lol!
