  • 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.

Food Energy

Food energy is chemical energy that animals derive from their food and molecular oxygen through the process of cellular respiration. Humans and other animals need a minimum intake of food energy to sustain their metabolism and to drive their muscles.

Organisms derive food energy from carbohydrates, fats and proteins as well as from organic acids, polyols, and ethanol present in the diet. Some diet components that provide little or no food energy, such as water, minerals, vitamins, cholesterol, and fiber, may still be necessary to health and survival for other reasons. 

Using the International System of Units, researchers measure energy in joules (J) or in its multiples; the kilojoule (kJ) is most often used for food-related quantities. An older metric system unit of energy, still widely used in food-related contexts, is the "food calorie" or kilocalorie (kcal or Cal), equal to 4.184 kilojoules. 

<>Fats and ethanol have the greatest amount of food energy per mass, 37 and 29 kJ/g (8.8 and 6.9 kcal/g), respectively. Proteins and most carbohydrates have about 17 kJ/g (4.1 kcal/g). 

Conventional food energy is based on heats of combustion in a bomb calorimeter and corrections that take into consideration the efficiency of digestion and absorption and the production of urine.
