nu sunt deloc confuz...

si sa te lamuresc cu b12 , ca ti-am ramas dator .....
Hehe, b12 este o vitamina ce se gaseste in intestinul animalelor si al omului, deoarece este "produsa" de bacteriile de acolo. Orice produs de fermentatie contine B12, drojdia de bere contine toate vitaminele B, spirulina contine B12.
Numarul de cazuri de carente in B12, se intalnesc in egala masura in randul celor vegetarieni cat si in randul celor carnivori, pentru ca ea nu tine de cantitatea de carne pe care o ingeri ci tine de functionarea optima a sistemului tau digestiv. Deci daca nu iti functioneaza sistemul digestiv , ai carenta de B12.

eu stiam ca B12 nu se gaseste in niciun fel de planta.

corect cu 2 exceptii drojdia de bere
iar cu spirulina e ceva interesant si controversat
" Neither plants nor animals are independently capable of constructing Vitamin B12.[4] Only bacteria have the enzymes required for its synthesis. The total synthesis of B12 was reported by Robert Burns Woodward[5] and Albert Eschenmoser in 1972,[6][7] and remains one of the classic feats of organic synthesis. Species from the following genera are known to synthesize B12: Aerobacter, Agrobacterium, Alcaligenes, Azotobacter, Bacillus, Clostridium, Corynebacterium, Flavobacterium, Micromonospora, Mycobacterium, Nocardia, Propionibacterium, Protaminobacter, Proteus, Pseudomonas, Rhizobium, Salmonella, Serratia, Streptomyces, Streptococcus and Xanthomonas.

Industrial production of B12 is through fermentation of selected microorganisms.[8] Streptomyces griseus, a bacterium once thought to be a yeast, was the commercial source of vitamin B12 for many years.[9][10] The species Pseudomonas denitrificans and Propionibacterium shermanii are more commonly used today.[11] These are frequently grown under special conditions to enhance yield, and at least one company, Rhône-Poulenc of France, at one point used genetically engineered versions of one or both of these species. It is not clear whether Sanofi-Aventis, the company which the pharmaceutical division of Rhône-Poulenc merged into, has continued the use of genetically modified organisms." ----- De pe wiki. asta asa rapid .....

Pe langa hamei, spirulina, soia, vitamina B12 se mai gaseste si in lucerna si alga marina..:-)

Soya e singura pe care as putea s-o consum dintre cele mentionate mai sus.
