All about fruitarianism with a long-term fruitarian, Lena

Fruitarian Philosophy

Fruitarian philosophy - system of fruitarian philosophical thought, the theoretical basis of fruitarianism, rational arguments for and against it, general presentation and definitions.

  • Defining Fruitarianism

    I was adjusting my definition of fruitarianism for 20 years, periodically changing it after reflecting on what I learned and experienced. You can read it on the top of the page, and the current version is this: 

    Fruitarianism - a quest for optimal ethical ways to live and diets based on fruits and seeds. 

    This is the line I just attempted to add to the definition of fruitarianism on the Wikipedia page
    "Fruitarianism can also be viewed as a set of ethical values, including respecting lives of plants, and their implementation in lifestyle." But I could not find eligible resources to cite.

    Wiki is the most popular resource online, and the article dedicated to fruitarianism requires some explanation for most people who are new to the term. In this article, I will also give my personal perspective of a practicing skeptic fruitarian.

  • 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.

Dalai Lama

Life is as dear to a mute creature as it is to a man. Just as one wants happiness and fears pain, just as one wants to live and not to die, so do other creatures.

Food Energy

Food energy is chemical energy that animals derive from their food and molecular oxygen through the process of cellular respiration. Humans and other animals need a minimum intake of food energy to sustain their metabolism and to drive their muscles.

Organisms derive food energy from carbohydrates, fats and proteins as well as from organic acids, polyols, and ethanol present in the diet. Some diet components that provide little or no food energy, such as water, minerals, vitamins, cholesterol, and fiber, may still be necessary to health and survival for other reasons. 

Using the International System of Units, researchers measure energy in joules (J) or in its multiples; the kilojoule (kJ) is most often used for food-related quantities. An older metric system unit of energy, still widely used in food-related contexts, is the "food calorie" or kilocalorie (kcal or Cal), equal to 4.184 kilojoules. 

<>Fats and ethanol have the greatest amount of food energy per mass, 37 and 29 kJ/g (8.8 and 6.9 kcal/g), respectively. Proteins and most carbohydrates have about 17 kJ/g (4.1 kcal/g). 

Conventional food energy is based on heats of combustion in a bomb calorimeter and corrections that take into consideration the efficiency of digestion and absorption and the production of urine.
