  • All Known Essential Minerals

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

    Macrominerals

    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.

  • Fruitarian Food Sources of Zinc

    I composed two lists with a few examples of the fruitarian food sources of zinc: fruits, seeds, seaweeds and mushrooms. You can compare the amounts of zinc in them with the recommended daily allowance of the mineral. RDA is usually around 20% higher than the amount needed for half of the healthy people. 

  • 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.

  • Zinc for the Common Cold

    The common cold is often caused by the rhinovirus. It is one of the most widespread illnesses and is a leading cause of visits to the doctor and absence from school and work. Complications of the common cold include ear infection, sinusitis and exacerbations of reactive airway diseases. There is no proven treatment for the common cold.  Zinc appears to interfere with the replication of rhinoviruses.

    Zinc inhibits replication of the virus and has been tested in trials for treatment of the common cold. In 18 randomised controlled trials with 1781 participants of all age groups, zinc was compared with placebo (no zinc). Zinc (lozenges or syrup) reduces the average duration of the common cold in healthy people, when taken within 24 hours of onset of symptoms.

Undernutrition

Undernutrition is a form of malnutrition. (Malnutrition also includes overnutrition).

Undernutrition can result from:

  • inadequate ingestion of nutrients,
  • malabsorption,
  • impaired metabolism,
  • loss of nutrients due to diarrhea,
  • increased nutritional requirements.

Undernutrition progresses in stages: it may develop slowly when it is due to anorexia or very rapidly. First, nutrient levels in blood and tissues change, followed by intracellular changes in biochemical functions and structure. Ultimately, symptoms and signs appear. Diagnosis is by history, physical examination, body composition analysis, and sometimes laboratory tests. 

Undernutrition from micronutrient deficiencies, or "hidden hunger", affects over 2 billion people globally and can lead to reduced growth and cognitive development, birth defects, blindness, and overall poor health. Vitamin A deficiencyiron deficiency anaemia and iodine deficiency disorders are among the most common forms of micronutrient malnutrition.
