All about fruitarianism with a long-term fruitarian, Lena

A survey of naturally occurring plant-derived food sources with high Vitamin B12 contents suggested that dried purple laver (nori, Porphyra yezoensis) is the most suitable Vitamin B12 source presently available for vegetarians.

The amount of total vitamin B12 in the dried purple laver was estimated to be 55 -59 mcg / 100 g dry weight. The purple laver contained 5 types of biologically active vitamin B12 compounds (cyano-, hydroxo-, sulfito-, adenosyl- and methylcobalamin), in which the vitamin B12 coenzymes (adenosyl- and methylcobalamin) comprised about 60 % of the total vitamin B12: 

  • cyanocobalamin
  • hydroxocobalamin 
  • sulfitocobalamin 
  • adenosylcobalamin 
  • methylcobalamin 

Dried purple laver also contains high levels of other nutrients that are lacking in vegetarian diets, such as iron and n-3 polyunsaturated fatty acids. Dried purple laver is a natural plant product and it is suitable for most people in various vegetarian groups.

Carotenoids

Carotenoids are a class of more than 750 pigments synthesized by plants, algae, and photosynthetic bacteria. These richly colored molecules are the sources of the yellow, orange, and red colors of many plants. Fruit and vegetables provide most of the 40 to 50 carotenoid phytonutrients found in the human diet.

The most common carotenoids in North American diets are α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, and lycopene. 

Provitamin A carotenoids - α-carotene, β-carotene, and β-cryptoxanthin - can be converted by the body to retinol (vitamin A), but not lutein, zeaxanthin, and lycopene. 

Dietary lutein and zeaxanthin help maintain optimal visual function - they absorb damaging blue light that enters the eye.

The results of observational studies suggest that diets high in carotenoid-rich fruit and vegetables are associated with reduced risks of cardiovascular disease and some cancers. But high-dose β-carotene supplements did not
