All about fruitarianism with a long-term fruitarian, Lena


  • All Known Essential Minerals

    Minerals (nutrients) are inorganic substances (contain no carbon) that are necessary for normal body function and development.


    Macro-minerals are needed in large doses (approximate recommended daily intake, milligrams (mg) per day ): 

    1. potassium, K (3500 mg) - metal, ions are necessary for the function of all living cells; 
    2. chloride, Cl− (3400 mg) - essential electrolyte in all body fluids; 
    3. sodium, Na, natrium (2400 mg) - metal, essential for all animals and some plants;
    4. calcium, Ca (1000 mg) - metal, essential for living organisms, produced in supernova nucleosynthesis;
    5. phosphorus, P (1000 mg) - in the form of the phosphate is required for all known forms of life; 
    6. choline (425 - 550 mg) - essential vitamin-like (vitamin B4) nutrient, synthesized in human body, but not sufficiently;
    7. magnesium, Mg (350 mg) - metal, essential for all known living organisms;

    Trace Minerals

    Trace minerals are needed in very small amounts (recommended daily intake, milligrams (mg) or micrograms (mcg) per day: 

    1. iron, Fe (15 mg) - metal, found in nearly all living organisms;
    2. zinc, Zn (8 - 11 mg) - metal, essential for humans and other organisms;
    3. manganese, Mn (5 mg) - metal, toxic essential trace element;
    4. fluorineF, fluoride ion, F− (3 - 4 mg) - a beneficial poisonous element, essential for bone solidity;
    5. copper, Cu (2 mg) - metal, essential to all living organisms;
    6. iodine, I (150 mcg) - a key component of thyroid hormones;
    7. selenium, Se (35mcg) - toxic in large doses, essential micronutrient for animals;
    8. chromium, Cr (30 mcg) - chromium (III) is questionably essential for humans.

  • Zinc

    Zinc is a nutritionally essential mineral needed for catalytic, structural, and regulatory functions in the body.

    The RDA (recommended daily allowance) for adult women and men is 8 mg a day and 11 mg a day of zinc, respectively.

    Severe zinc deficiency is a rare, genetic or acquired condition. Dietary zinc deficiency, often called marginal zinc deficiency, is quite common in the developing world, affecting an estimated 2 billion people. Zinc deficiency can cause impaired growth and development in children, pregnancy complications, immune dysfunction, and increased susceptibility to infections. Long-term consumption of zinc in excess of the tolerable upper intake level of 40 mg a day for adults can result incopper deficiency.

    Zinc bioavailability is relatively high in meat, eggs, and seafood. Zinc is less bioavailable from whole grains and legumes due to the inhibitory effects of phytic acid on absorption of the mineral.

If people are good only because they fear punishment, then we are a sorry lot indeed. 


Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products, one of the basic food groups.

Sugar is the generalized name for sweet, short-chain, soluble carbohydrates, many of which are used in food. They are composed of carbon, hydrogen, and oxygen. Simple sugars are called monosaccharides and include glucose (or dextrose), fructose, and galactose. The table sugar most customarily used as food is sucrose - hydrolyses into fructose and glucose in the body. Other disaccharides include maltose and lactose. Longer chains of sugars are called oligosaccharides. 

Starch is a polymeric carbohydrate consisting of a large number of glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as an energy store. It is the most common carbohydrate in human diets and is contained in large amounts in staple foods such as potatoes, wheat, maize (corn), rice. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. 

Fiber is consists of non-starch polysaccharides such as arabinoxylans, cellulose, and many other plant components such as resistant starch, resistant dextrins, inulin, lignin, chitins, pectins, beta-glucans, and oligosaccharides, and are derived from plants. Dietary fibers are not digested by gastrointestinal enzymes. Soluble fiber dissolves in water, changes as it goes through the digestive tract, where it is fermented by bacteria, partially into physiologically active byproducts - healthful compounds. Insoluble fiber does not dissolve in water and stays intact as it moves through your digestive system, can be prebiotic and metabolically ferment in the large intestine. Dietary fibers can change absorption of other nutrients and chemicals. Some soluble plant fibers can modulate intestinal inflammation and are contrabiotic. Many types of so-called dietary fiber are not actually fibrous. Apple
