All about fruitarianism with a long-term fruitarian, Lena

A plant-based diet is a diet of any animal (including humans) based on foods derived from plants, including vegetables, whole grains, legumes and fruits, but with few or no animal products

"Plant-based diet" has been used to refer to the following diets:

  • Vegan diet - no food from animal sources.
    • Fruitarian  - consists primarily of fruit.
    • Raw vegan - food is uncooked and sometimes dehydrated.

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
