only in the last 50 years has it been possible to survive as a strict vegetarian. The reason people can now is that we can harvest vitamin b12 from animal/bacterial sources (also possible to synthesis in lab) and add it to cereals/bread/pasta/proccesed vegtable products/etc. Deficiency causes nerve degeneration and irreversible neurological damage, DNA replication problems, anaemia (excessive tiredness, breathlessness, listlessness, pallor, and poor resistance to infection), and blindness due to degeneration of optic nerve. *side notes: It is possible to build up stores of this vitamin that last for years. There are other dietary issues that are also "solved" by supplement enriched foods. |
I'm assuming when you say strict vegetarian you mean vegan, otherwise eggs would be fine for b12. Just remember it's a way of life, it doesn't necessarily mean it's better or worse for you.
