Efficiency of getting nutrients from vegetables

[Guest guest]

I was eating a salad made from raw vegetables today,

and that got me thinking about how efficient is

getting nutrients from vegetables. I've heard that

humans lack cellulose digesting enzymes, and since all

nutrients in plants are protected by the cellulose, we

really need to chew them really, really well, if we

eat them raw. Otherwise, the vegetables (they are

mostly the hardy ones) will end up being just

roughage. Maybe that's why Bieler's broths were so

effective for what he used them -- the cellulose was

softened by cooking.
