All about fruitarianism with a long-term fruitarian, Lena

An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized by the organism, and must be supplied in diet. 

The 9 amino acids humans cannot synthesize (F V T W M L I K H):

  • phenylalanine
  • valine
  • threonine
  • tryptophan
  • methionine
  • leucine
  • isoleucine
  • lysine
  • histidine

Animal and plant proteins are made up of about 20 common amino acids.

Synthesis of 6 other amino acids - conditionally essential - can be limited under special conditions (R C G Q P Y)arginine, cysteine, glycine, glutamine, proline, and tyrosine.

Dispensable amino acids can be synthesized in the human body, 5 (A D N E S): alanine, aspartic acid, asparagine, glutamic acid and serine .

Fructose, Glucose, Sucrose - Sugars in Plant Foods

  • Fructose and glucose are simple sugars, monosaccharides, with the general formula C6H12O6
    • Fructose, or fruit sugar, occurs naturally in fruits, some root vegetables, cane sugar and honey and is the sweetest of the sugars. 
    • Glucose, dextrose or grape sugar, occurs naturally in fruits and plant juices and is the primary product of photosynthesis. Most ingested carbohydrates are converted into glucose during digestion and it is the form of sugar that is transported around the bodies of animals in the bloodstream. 
  • Sucrose is a compound sugar, disaccharide, with the general formula C12H22O11
    Sucrose is found in the stems of sugarcane and roots of sugar beet. It also occurs naturally alongside fructose and glucose in other plants, in particular fruits and some roots (carrots). A molecule of sucrose is formed by the combination of a molecule of glucose with a molecule of fructose, and it is split into these parts during digestion.

The different proportions of sugars found in plant foods determines their sweetness
