  • 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. fluorine, F, 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.

I'd like everybody to be a vegetarian... In 100 or 200 years time, we may look back on the way we treated animals today as something like we today look back on the way our forefathers treated slaves.

Fruits and Vegetables

Fruit and vegetable consumption is a focus of research and nutrition education, but there is no universal agreement on the meaning of 'fruits and vegetables'. Foods that require specific instruction include rice, dried beans, potatoes, tomatoes and fruits and vegetables in mixtures and condiments. 

Fruit and vegetables are important components of a healthy diet, and their sufficient daily consumption could help prevent major diseases. A recently published WHO/FAO report recommends a minimum of 400g of fruit and vegetables per day (excluding potatoes and other starchy tubers) for the prevention of chronic diseases such as heart disease, cancer, diabetes and obesity, as well as for the prevention and alleviation of several micronutrient deficiencies. 

Fruits and vegetables are universally promoted as healthy. The Dietary Guidelines for Americans 2010 recommend you make one-half of your plate fruits and vegetables.

Fruits and vegetables include a diverse group of plant foods that vary greatly in content of energy and nutrients. Fruits and vegetables supply dietary fiber, vitamins and minerals to the diet and are sources of phytochemicals (phytonutrients) that function as antioxidants, phytoestrogens, and antiinflammatory agents and through other protective mechanisms.
