Potassium, the third most abundant mineral in the human body, is an essential mineral whose ions are vital for the functioning of all living cells!  Potassium plays a role at both the cellular and electrical level – considered and electrolyte because it carries a tiny electrical charge – it is found in red blood cells, muscles and bones.  Our bodies use potassium ions to conduct electrical impulses along muscle and nerve cells, it helps to boost the efficiency of nerve reflexes that transmit messages from one body part to another, this in turn helps in muscle contraction to perform various activities without tiring quickly. 

Potassium also has vasodilating properties that work to relieve the tension of blood vessels which is one of the main causes of high blood pressure.  It is helpful in reversing the role of sodium in unbalancing normal blood pressure thus acting as a vital component that maintains the normality of blood pressure in the human body.  The importance of potassium should not be underestimated in your dietary plan, most famously found in bananas other rich sources of potassium include spinach, avocados and coconut water.

Potassium contributes to:

·         normal functioning of the nervous system

·         normal muscle function

·         the maintenance of normal blood pressure

Iron is needed for a number of highly complex processes that continuously take place in the body on a molecular level and that are indispensable to human life.  Formation of haemoglobin is the chief function of this mineral – this is the primary protein found in red blood cells and represents about two thirds of the body’s iron.  Haemoglobin binds to the oxygen molecules that you breathe in from the air and releases them into your tissues.  The brain receives around 20% of the blood oxygen and a proper flow of blood to the brain can stimulate cognitive activity and help to create new neural pathways, it is especially important that children consume enough iron in their diet – iron deficiency in the first two years of a child’s life is associated with delayed cognitive and psychomotor development.  

Ribonucleic reductase is an iron dependant enzyme that is required for DNA synthesis (cell division), thus iron is required for a number of functions including healing and immune function - red blood cells are necessary for providing oxygen to damaged tissues, organs and cells.  Iron is also involved in food metabolism and is a cofactor and activator for some enzymes which play key roles in energy production and metabolism.  If iron stores are low symptoms can include tiredness, fatigue and dizziness.  Dietary iron has two forms, heme (animal based) and non-heme (plant based), important sources are; grass fed beef, oysters, spinach, lentils and beans.

Iron contributes to:

·         normal cognitive function

·         normal energy-yielding metabolism

·         normal formation of red blood cells and haemoglobin

·         normal oxygen transport in the body

·         normal function of the immune system

·         the reduction of tiredness and fatigue

·         normal cognitive development of children

·         Iron has a role in the process of cell division

Zinc is a metal that functions as an essential nutrient in the body, it is found in every cell and has been used since ancient times, with Ayurvedic texts dating as far back as the 14^th century recommending its application in various forms.  Although only required in limited amounts, zinc supports important bodily processes like strengthening the immune system – your body needs zinc to make T-cells, a type of white blood cell that fights off foreign invaders in your bloodstream.  With antioxidant properties, zinc helps to protect the cells in the body from damage by free radicals and supports the catalytic activity of various enzymes essential in DNA synthesis and cell division.  In males, zinc assists in spermatogenesis (the production of mature spermatozoa) and is a critical mineral for robust testosterone levels, in females it aids in all the reproductive phases including the birth and lactation stages. 

Zinc is an essential component of over 300 enzymes participating in the metabolism of carbohydrates, fatty acids, proteins and other macronutrients and has a regulatory role in vitamin A transport mediated through protein synthesis.  The intake of zinc has a positive influence on bone mass, it is an important cofactor in the stimulation of bone building osteoblasts (cells that synthesize bone), it accelerates the renewal of skin cells and it is essential for healthy nails and shiny hair.  Zinc is vital for vision with high concentrations found in the retina and may also protect from night blindness and prevent the development of cataracts.  This super nutrient also plays a crucial role in memory formation and cognitive stability, ensuring a proper intake of zinc is an important step towards optimal brain function.  Topping the list of zinc rich foods are oysters, however seeds such as chia, sunflower, hemp and pumpkin are also rich sources of this important mineral.

Zinc contributes to:

·         normal DNA synthesis

·         normal acid-base metabolism

·         normal carbohydrate metabolism

·         normal cognitive function

·         normal fertility and reproduction

·         normal macronutrient metabolism

·         normal metabolism of fatty acids

·         normal metabolism of Vitamin A

·         normal protein synthesis

·         the maintenance of normal bones

·         the maintenance of normal hair

·         the maintenance of normal nails
