All about fruitarianism with a long-term fruitarian, Lena

An increase in total fruit intake was associated with a change in weight of -0.53 lb (a weight loss of 0.24 kg), and an increase in total vegetable intake was associated with a weight change of -0.25 lb (a weight loss of 0.11 kg) - for each extra daily serving over a 4 years period.

133,468 US men and women were followed for up to 24 years. The benefits of increased consumption were strongest for berries, apples or pears, tofu (soy), cauliflower, and cruciferous and green leafy vegetables. Increased satiety with fewer calories could be partly responsible. Obesity is a primary risk factor for many life-shortening health conditions.

Charles Darwin

There is no fundamental difference between man and animals in their ability to feel pleasure and pain, happiness, and misery. 

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).
