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.

Grains

Grains are small, hard, dry seeds, with or without attached hulls or fruit layers, harvested for human or animal consumption. The two main types of commercial grain crops are cereals (e.g. wheat, rye) and legumes (e.g. beans, soybeans). Seeds

After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (e.g. plantains, breadfruit) and tubers (e.g. sweet potatoes, cassava). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported, stored for long periods, and milled for flour or pressed for oil. Major global commodity markets exist for canola, maize, rice, soybeans, wheat, and other grains but not for tubers, vegetables, or other crops.
