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).
A sharp distinction between humans and “animals” is essential if we are to bend them to our will, make them work for us, wear them, eat them–without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeeling toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.
Antioxidants - substances that may prevent or delay some types of cell damage. Examples of antioxidants include beta-carotene, lutein, lycopene, selenium, vitamins A, C and E.
Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet with lots of vegetables and fruits is healthy and lowers risks of certain diseases. But it isn't clear whether this is because of the antioxidants, something else in the foods, or other factors. Most clinical studies of antioxidant supplements have not found them to provide substantial health benefits.
