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.

 

Albert Schweitzer

The thinking man must oppose all cruel customs no matter how deeply rooted in tradition and surrounded by a halo. When we have a choice, we must avoid bringing torment and injury into the life of another, even the lowliest creature; to do so is to renounce our manhood and shoulder a guilt which nothing justifies. 

Enterotypes and Microflora

An enterotype is a classification of living organisms based on its bacteriological ecosystem in the gut microbiome. Humans can be roughly divided into three enterotypes depending on which genus of bacteria dominates their gut: Bacteroides, Ruminococcus, or Prevotella. 

  • People who eat a lot of meat and saturated fat tended to have more Bacteroides in their flora
  • Ruminococcus prevailed in people who consumed lots of alcohol and polyunsaturated fats. 
  • Prevotella favored a diet rich in carbohydrates.

Long-term diet is strongly associated with the gut microbiome composition. If switching gut enterotype is possible, it may take a long-term dietary intervention. 

Chimpanzees have enterotypes that are compositionally analogous to those found in humans.
