All about fruitarianism with a long-term fruitarian, Lena

Food plants are known to produce a wide array of chemicals. The levels of many of the more toxic ones have been reduced by hybridisation, but many of these natural toxins are still present at low levels. Eating very large amounts of one type of such foods can possibly be somewhat toxic.

Common Plant Toxins and Antinutrients

Toxins (occurrence in plant foods) - possible effect on humans and animals in large amounts:
  • Cyanogenic glycosides (sweet potatoes, stone fruits, lima beans) - gastrointestinal inflammation, inhibition of cellular respiration.
  • Glulcosinolates (canola, mustard, radish, cabbage, peanut, soybean, onion) - impaired metabolism, reduced iodine uptake, decreased protein digestion.
  • Glycoalkaloids (potato, tomato) - depressed central nervous system, kidney inflammation, carcinogenic, birth defects, reduced iron absorption.
  • Gossypol (cottonseed) - reduced iron uptake, spermicidal, carcinogenic.
  • Lectins (most cereals, soybeans, other beans, potatoes) - intestinal inflammation, decreased nutrient absorption.
  • Oxalate (spinach, rhubarb, tomato) - reduces solubility of calcium, iron, and zinc.
  • Phenols (most fruits and vegetables, cereals, soybean, potato, tea, coffee) - destroys thiamine, raises cholesterol, estrogen-mimic.
  • Coumarins (celery, parsley, parsnips, figs) - light-activated carcinogens, skin irritation.

Erich Fromm

It is naively assumed that the fact that the majority of people share certain ideas and feelings proves the validity of these ideas and feelings. Nothing could be further from the truth. Consensual validation as such has no bearing on reason or mental health.

Genetics

Genetics is the study of genes, genetic variation, and heredity in living organisms. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. 

The Human Genome Project has estimated that humans have 20,000 - 25,000 genes. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but less than 1% of genes are slightly different between people. Poplar tree genome suggests more than 45,000 genes.
