All about fruitarianism with a long-term fruitarian, Lena

Provitamin A carotenoids are found in green leafy vegetables (e.g. spinach, amaranth, and young leaves from various sources), yellow vegetables (e.g. pumpkins, squash, and carrots), and yellow and orange non-citrus fruits (e.g. mangoes, apricots, and papayas).

Red palm oil produced in several countries worldwide is especially rich in provitamin A.

Some other indigenous plants also may be unusually rich sources of provitamin A: 

  • palm fruit known in Brazil as burití, found in areas along the Amazon River (as well as elsewhere in Latin America), 
  • fruit known as gac in Viet Nam (used to colour rice).

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
