All about fruitarianism with a long-term fruitarian, Lena

Serum vitamin B12, serum folate and red blood cell folate levels were examined among 36 strict vegans of 5-35 years' duration.

Vitamin B12 levels among the vegans were generally lower than in a control population. Most of the vegans had vitamin B12 values less than 200 pg/ml

None of the vegans had any hematologic evidence of vitamin B12 deficiency, however four of them had neurologic complaints. Long-standing vegans should be monitored for vitamin B12 levels.

Red blood cell folate levels were normal but serum folate levels among the vegans were higher than among the controls. 

Albert Schweitzer

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. 

Phenylalanine

Phenylalanine is an essential amino acid.

Provided by diet, phenylalanine can be converted into another amino acid, tyrosine, in the body. Tyrosine is used to synthesize two key neurotransmitters that promote alertness: dopamine and norepinephrine. 

It has 3 forms:

  • D-phenylalanine;
  • L-phenylalanine - most common, the form in which phenylalanine is incorporated into the body’s proteins;
  • DL-phenylalanine.
