All about fruitarianism with a long-term fruitarian, Lena

I composed two lists with a few examples of the fruitarian food sources of zinc: fruits, seeds, seaweeds and mushrooms. You can compare the amounts of zinc in them with the recommended daily allowance of the mineral. RDA is usually around 20% higher than the amount needed for half of the healthy people. 

The RDA (recommended dietary allowance) of zinc for healthy adult women and men is 8 mg a day and 11 mg a day, respectively. 

Examples of high in zinc plant food sources, fruits and seeds: 

  • Sesame seeds, whole, dried (~ 8 mg /100 g or ~ 1/5 of a pound, lb)
  • Pumpkin and squash seeds, dried - pepitas (~ 7 mg /100 g)
  • Pine seeds (~ 6 mg / 100 g) 
  • Sunflower seeds (~ 5 mg /100 g)
  • Tomatoes, sun-dried (~ 2 mg in 100 g)
  • Lentils, sprouted (~ 2 mg in 100 g)
  • Almonds (~ 1 mg zinc in about 25 whole almonds)
  • Green peas, fresh or unfrozen (~ 1 mg zinc in 1 cup)
  • Avocados (~ 1 mg zinc in one bigger fruit)
  • Blackberries (~ 0.8 mg zinc in one cup - 150 g)

Other fruitarian foods high in zinc, algae and mushrooms:

  • Seaweed agar, dried (~ 6 mg zinc in 100 g)
  • Seaweed, spirulina, dried (~ 2 mg zinc in 100 g)
  • Seaweed kelp, raw (~ 1 mg in 100 g)
  • Mushrooms, shiitake (~ 1 mg in 100 g)

Carl Sagan

A sharp distinction between humans and “animals” is essential if we are to bend them to our will, make them work for us, wear them, eat them–without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeeling toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.

Vitamin B12 Cobalamin

Vitamin B12, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system, and the formation of red blood cells. It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism.

No fungi, plants, nor animals (including humans) are capable of producing vitamin B12. Only bacteria and archaea have the enzymes needed for its synthesis. Proved food sources of B12 are animal products (meat, fish, dairy products). Some research states that certain non-animal products possibly can be a natural source of B12 because of bacterial symbiosis.

B12 is the largest and most structurally complicated vitamin and can be produced industrially only through a bacterial fermentation-synthesis. This synthetic B12 is used to fortify foods and sold as a dietary supplement.

Vitamin B12 consists of a class of chemically related compounds (vitamers), all of which show pharmacological activity. It contains the biochemically rare element cobalt (chemical symbol Co). The vitamer is produced by bacteria as hydroxocobalamin, but conversion between different forms of the vitamin occurs in the body after consumption

B12 aids in lowering homocysteine levels and may lower the risk of heart disease. 

Recommended daily amount: 2.4 mcg

Example sources: fortified cereals, doenjang and chunggukjang (fermented soybeans), nori (seaweed).
