All about fruitarianism with a long-term fruitarian, Lena

Protein plays a crucial role in almost all biological processes and amino acids are the building blocks of it.

A large proportion of our cells, muscles and tissue is made up of amino acids - 20% Of the human body is made up of protein. 

~500 Amino acids are known, 20 appear in the genetic code, 9 are essential for humans because they cannot be created from other compounds by the human body, and must be taken from food.

Amino acids carry out many important bodily functions: 

  • give cells their structure;
  • play a key role in the transport and the storage of nutrients;
  • have an influence on the function of organs, glands, tendons and arteries;
  • essential for healing wounds and repairing tissue; 
  • important removal of waste deposits.

The question is not, "Can they reason?" nor, "Can they talk?" but "Can they suffer?” 

Carotenoids

Carotenoids are a class of more than 750 pigments synthesized by plants, algae, and photosynthetic bacteria. These richly colored molecules are the sources of the yellow, orange, and red colors of many plants. Fruit and vegetables provide most of the 40 to 50 carotenoid phytonutrients found in the human diet.

The most common carotenoids in North American diets are α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, and lycopene. 

Provitamin A carotenoids - α-carotene, β-carotene, and β-cryptoxanthin - can be converted by the body to retinol (vitamin A), but not lutein, zeaxanthin, and lycopene. 

Dietary lutein and zeaxanthin help maintain optimal visual function - they absorb damaging blue light that enters the eye.

The results of observational studies suggest that diets high in carotenoid-rich fruit and vegetables are associated with reduced risks of cardiovascular disease and some cancers. But high-dose β-carotene supplements did not
