Sorry to go a little off topic, but according to my dietician, the type of B12 our bodies need can only come from animal sources? B12 analogues she called it. Does anyone have knowledge on this?
i'm gonna say wrong. animals don't produce b12, they have it in their bodies because when they eat, they eat bits of soil with the bacteria in it. so it's all one source.
hi there, just a quick philosophical question for you.
How Do Vegans Exist, then?
are we just ignoring that Veganism has been around longer than the term was coined and that many people have lived full lives as Vegans?
I mean.. just a tiny fact worth consideration.
Edit:
oh! I wasn't being rude, that is just a pet peeve of logic that always gets me. um but knowledge... well just some information, unsure of its' scientific truth.
people were excited about spirulina (or a similar algae rich in soluble/digestible b12) due to it being a supposedly rich source of readily available nutrients.
but then a study was done that suggested the b12 provided by the algae were infact 'analogs'...
think of a virus.
an analog (from memory and in this context) is like a virus cell, in the way that it is called 'dead'. the b12 molecule fits the receptor, but does not function actively. thus it is actually a negative thing to have analogs of nutrients clogging up your system. was my understanding anyway.
ummmm another way to grasp this is through plants.
certain plants "require" certain nutrients.. simply because where they evolved/adapted/acclimatized/adjusted to symbiotically had soil of this constitution.
anyway... a little pithy: "one sign of a deficiency, is that of an excess' or an excess is a key sign deficiencies will be present. because ... think osmosis... when a thing is saturated, it is just that. it cannot 'absorb' any more.
thus an intricate system flooded with a highly soluble inorganic matter like salt, probably blocks the absorption of essential nutrients in the right balance.
sorry. plants! so when a plant has too much iron available, the leaves tend to die because it cannot get enough moisture, due to not being able to absorb other essential trace elements. thus an excess of one vital thing, causes a deficiency of another even if it is readily available.
oh if you ever wondered why soil PH (acid - alkaline) is so important, it is simply that plants are accustom to certain nutrients and certain nutrients become available to the plant when the soil is in different PH conditions. so acid and alkaline versions of the same soil would have different molecular structure. the acidity causes reactions between nutrients and so on.
hope that kinda helped. there have been studies saying that there is sufficient B12 RDI tested in ground water! *shrugs* noone cares to check things which will cause discoveries that cost them money. lol why discover something when people can simply live a life 'coping' without vital sustenance that could make their brain work properly to solve these problems. lol. who would be smart enough to promote such a discovery! ... when everyone suffers the same.
*le sigh
