All about fruitarianism with a long-term fruitarian, Lena

Vitamin B(12) concentrations of dried green (Enteromorpha sp.) and purple (Porphyra sp.) lavers nori were determined, in micrograms: 

  • green nori: 64 - 69 mcg per 100 g of dry weight,
  • purple nori: 32 - 25 mcg per 100 g of dry weight.

Non-coenzyme forms (hydroxo and cyano forms) of vitamin B12 predominate in both. 

Recommended dietary amounts (RDAs) for cobalamin, B12, are 2.4 mcg (micrograms) daily, one can cover it with 4 g of dry green nori. 

The dried lavers contained lesser amounts of dietary iodine (~ 4-6 mg per 100 g of dry weight) relative to other seaweeds, suggesting that excessive intake of the dried lavers is unlikely to result in harmful intake of iodine.

These results indicate that the nori are the best source of vitamin B12 among edible seaweeds, especially for strict vegetarians (vegans).

Charles Darwin

There is no fundamental difference between man and the higher animals in their mental faculties . . . The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery.

Nitrogen Balance

Nitrogen balance is a measure of nitrogen input minus nitrogen output

Nitrogen Balance = Nitrogen intake - Nitrogen loss

Nitrogen is a fundamental component of amino acids, which are the molecular building blocks of protein. Measuring nitrogen inputs and losses can be used to study protein metabolism. Apple
