All about fruitarianism with a long-term fruitarian, Lena

Fruitarian

Fruitarian diet is based on fruits and seeds and excludes animal products.

  • My Fruitarian Story

    This is me.

    Hi, my real name is Lena, I founded this site Fruitarians.net in 2010 as an international fruitarian community. 

    Fruitarianism for me is a quest for optimal ethical ways to live and for all good diets based on fruits and seeds.  

    I am a long term vegan-fruitarian, who radically changed her lifestyle as a teenager, at 18, and maintained and adjusted it during two following decades. I doubted fruitarianism, but my fruitarian position remains surprisingly strong. This a very short version of my fruitarian story.

  • Open Letter

    Hi, thank you for checking out Fruitarians.net! My name is Lena, I am also known as Fruitarian Lena. I am a long-term vegan fruitarian, the founder of the site (the former International Fruitarian Network) - my attempt to provide an independent inviting platform for all people to tell about their ethical lifestyle choices, and to participate in the civil public debate. Currently, I am considering my options in building an interesting resource on fruitarianism. 

    I believe the future of humanity depends on our ability to come to certain agreements

    If you are interested in realistic approaches to fruitarianism and veganism, in ethical and environmental changes we can make, and in attracting people to an open conversation about these topics, beyond cooking, looks and fitness, please help me to to develop Fruitarians.net with new ideas and to join the conversation in public videos.

    My plans for the future of this site are summarized in this public letter to past and future participants and supporters.

Protein Digestibility-Corrected Amino Acid Score

The protein digestibility-corrected amino acid score (PDCAAS) has been adopted by FAO/WHO as the preferred method for the measurement of the protein value in human nutrition. 

PDCAAS = Amino Acid Score x Digestibility

The method is based on comparison of the concentration of the first limiting essential amino acid in the test protein with the concentration of that amino acid in a reference (scoring) pattern. This scoring pattern is derived from the essential amino acid requirements of the preschool-age child.

Although the principle of the PDCAAS method has been widely accepted, critical questions have been raised in the scientific community:

  1. the validity of the preschool-age child amino acid requirement values (more than 4 times greater than the EAA requirement for an adult),
  2. the validity of correction for fecal instead of ileal digestibility,
  3. the truncation of PDCAAS values to 100%.

The reference scoring pattern was based on studies performed more than 25 years ago on a limited number of 2-year-old children recovering from malnutrition.

According to the current official recommendations, a 2-year old child needs ~ 3x higher essential-to-non-essential amino acid ratio, and needs essential amino acids in different proportions than adult. Methionine/cysteine is the limiting essential amino acids for adults, and for children it is lysine or tryptophan.

The use of fecal digestibility overestimates the nutritional value of a protein because amino acid nitrogen entering the colon is lost for protein synthesis in the body and is, at least in part, excreted in urine as ammonia.
