All about fruitarianism with a long-term fruitarian, Lena

Notes: current

It has been seven years since I tried to find researches or philosophers who might be interested in fruitarianism. Back then I have joined but nobody seemed to be involved into anything close to fruitarian diet or ethics. I left this note on my profile (

Hi, I have joined this site for scientist (not being one myself) to find someone who is interested in researching nutritional aspect of fruitarianism. I hoped someone would be interested in a case study. I gave up, maybe too early. I'll keep this profile for the history, without participation, but you are welcome to contact me directly - thank you!

I am not as eager anymore to offer my time for this purpose, but I will definitely consider serious offers.

John Stuart Mill

A person may cause evil to others not only by his actions but by his inaction, and in either case he is justly accountable to them for the injury.

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. Apple
