Vitamin A is the name given to a group of fat-soluble antioxidant compounds.  Two different types of vitamin A are found in the diet; “preformed vitamin A” (also referred to as retinol or retinal) is found in animal products and “pro-vitamin A” is found in plant based foods - the most common type being beta-carotene.  It was the first fat soluble vitamin to be recognised and is sometimes referred to as the “anti-infective” vitamin due to its enhancement of the body’s immunity against infections by increasing the lymphatic responses against disease forming antigens.  It keeps the mucous membranes moist that line the mouth, respiratory passage and urinary tract and enhances the activity of white blood cells. 

Known as retinol because it produces the pigments in the retina in the eye, it enables your eyes to adjust to light changes, keeps the eyes moist and improves night vision.  It can also significantly reduce the risk of cataracts and macular degeneration.  Vitamin A helps to keep your body free from free radicals and toxins which might cause damage to your skin, helping to keep it soft and supple by ensuring moisture retention.  Vitamin A deficiency can impair iron metabolism which can lead to anaemia despite adequate iron intake.  Playing an important role in cells’ ability to adapt to perform specific functions in larger organs, the richest sources of preformed vitamin A are found in liver, kidney, butter and whole milk, whereas good sources of pro-vitamin A are dark green leafy vegetables and yellow-orange vegetables such as sweet potatoes and carrots.

Vitamin A contributes to:

·         normal iron metabolism

·         the maintenance of normal mucous membranes

·         the maintenance of normal skin

·         the maintenance of normal vision

·         the normal function of the immune system

·         Vitamin A has a role in the process of cell specialisation

Vitamin C, a water soluble vitamin also known as ascorbic acid, is one of the safest and most effective vitamins whose benefits are many.  It is absolutely vital in collagen production – collagen is a simple protein and an essential part of our connective tissue – the very framework of our body.  All of the components that hold our bodies together such as skin, bones, blood vessels, teeth and gums, tendons and cartilage rely upon collagen.  Vitamin C is directly responsible for influencing collagen synthesis and helps to shield us from the symptoms of collagen deletion – most famously scurvy! 

A powerful antioxidant, vitamin C can protect cells from the damaging effects of free radicals which are harmful by-products of digestion or foreign substances in the atmosphere.  Inside the body it changes form to a negatively charged compound called ascorbate which helps to protect nerve cells and improves psychological function.  It has been known as the antioxidant’s antioxidant because it functions to protect vitamin E from oxidation too, another vitamin that interacts with free radicals to prevent cell damage.  Vitamin C strongly enhances the absorption of iron - when they are consumed and digested together, vitamin C combines with the iron to form a compound that is more easily absorbed.  Crucial to the overall health of the body in its efforts to fight off infections – both bacterial and viral – white blood cells contain 20 times the amount of vitamin C than other cells and require constant replenishment to keep the immune system working to its optimum capacity, especially during and after intense physical exercise.    Whilst highly concentrated in citrus fruits, other rich sources of vitamin C are acerola cherries, leafy green vegetables, red peppers and potatoes.

Vitamin C contributes to:

·         normal collagen formation for the normal function of blood vessels

·         normal collagen formation for the normal function of bones

·         normal collagen formation for the normal function of cartilage

·         normal collagen formation for the normal function of gums

·         normal collagen formation for the normal function of skin

·         the reduction of tiredness and fatigue

·         the regeneration of the reduced form of vitamin E

·         Vitamin C increases iron absorption

Also known as thiamin, vitamin B1 is one of the eight water soluble vitamins in the vitamin B family.  It is a vital human nutrient playing an important role in how we convert our food into energy – when we consume our food it is broken down into simpler units such as carbohydrates, fats and amino acids, vitamin B1 plays a crucial role in utilising these units to produce energy.  This is especially true for cells in the brain where the energy demand is really high which is why it is also referred to as a “morale vitamin” for its positive effect on the nervous system and a healthy mental attitude! 

Promoting the health of the nervous system, vitamin B1 helps in the proper development of the myelin sheaths around nerves, improving the body’s ability to withstand stress, it is often called the “anti-stress” vitamin and is also reported to improve the memory and powers of concentration.  Thiamin is essential to the body’s cardiac heath, involved in blood formation and helping in the production of the neurotransmitter acetylcholine which is used to relay messages between the nerves and muscles to ensure proper cardiac function.  Brewer’s yeast and liver are the richest sources of vitamin B1, however, spirulina, linseeds, rye, wheat germ and kidney beans are also important sources of this vitamin.

Vitamin B1 contributes to:

·         normal energy-yielding metabolism

·         the normal functioning of the nervous system

·         normal psychological function

·         the normal function of the heart

Vitamin B2, also known as riboflavin, is a water soluble vitamin.  It is one of the eight B vitamins that are essential for human health and is found in a variety of foods, both plant based and animal based, and is not lost in cooking like many of the other vitamins.  Vitamin B2 is critical to the breakdown of dietary carbohydrates, fats and proteins into energy that you can use.  Without adequate riboflavin in the diet the enzymes involved in energy production do not function optimally which can lead to tiredness and stress. 

Working in tandem with other B vitamins, vitamin B2 helps to protect the nervous system and plays an important role in saving your body from oxidative stress caused by free radicals, serving as a component of the enzyme glutathione reductase which helps to neutralize free radicals.  Essential for the formation of fresh red blood cells, vitamin B2 also interacts with iron which is used to synthesize haemoglobin, allowing your body to get the oxygen rich blood needed to perform the daily functions of life.   Along with vitamin A, riboflavin also helps to maintain the mucous membranes in the digestive system.  Playing a major role in ensuring healthy corneas, perfect vision and radiant skin, vitamin B2 is best consumed as nature intended!  Dietary sources rich in this important vitamin include; dark leafy green vegetables, barleygrass, mushrooms, avocados, dairy products and wild rice.

Vitamin B2 contributes to:

·         normal energy yielding metabolism

·         the normal functioning of the nervous system

·         the maintenance of normal mucous membranes

·         the maintenance of normal red blood cells

·         the maintenance of normal skin

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

Forming 2% of total body weight in adults, calcium’s best known role is in bone and tooth health.  It forms a part of hydroxyapatite, the mineral complex that makes your bones and teeth hard and maintains bone density.  It is especially important that children consume an adequate amount of calcium to maximise their bone mass prior to adult years.  Also an important part of the blood clotting process, calcium works together with vitamin K and a protein called fibrinogen in the clotting cascade, without adequate levels of calcium and vitamin K the blood will take longer to clot.  Calcium helps your muscles contract in response to nerve stimulation, it activates a protein called calmodulin that your muscle cells need to provide the fuel they need to function.  Assisting in the transmission of neural impulses, the calcium in your body also aids other types of cell communication – it acts as a “second messenger” in your cells which means it responds to chemical signals from outside your cells and then triggers a response inside your cell. 

Calcium helps to activate several digestive enzymes and there is considerable evidence that calcium and vitamin D intake are influential in modulating energy metabolism in humans.  Like all minerals, calcium doesn’t work alone but in tandem with other nutrients such as magnesium and vitamin D, for this reason, obtaining our calcium from whole foods – foods whose nutrient profiles have been optimised by nature for superior absorption – is the best way to remain healthy!  Excellent natural calcium sources include; chia seeds, sesame seeds, seaweed (such as kelp and Kombu), dark leafy greens and dairy products (such as yoghurt, cheese and kefir).

Calcium contributes to:

·         normal blood clotting

·         normal energy-yielding metabolism

·         normal muscle function

·         normal neurotransmission

·         the normal function of digestive enzymes

·         Calcium has a role in the process of cell division and specialisation

·         Calcium is needed for the maintenance of normal bones

·         Calcium is needed for the maintenance of normal teeth

·         Calcium is needed for normal growth and development of bone in children

Next to calcium, phosphorus is the most abundant mineral in the body.  In order to be properly utilised it must be in proper balance with calcium and magnesium in the blood, these are the two minerals it works in tandem with to create strong bones and teeth, also helping to lay the foundation of a strong skeletal structure.  It is an essential part of our diet - especially as children when the most bone growth and development occurs.  Both DNA and RNA contain phosphorus which make it important for cellular reproduction. 

Phosphorus also contributes to the repair process and maintenance of various body cells which suffer from daily wear and tear, it makes up part of the phospholipids that surround cells - phospholipids help to protect and regulate what goes in and out of each cell.  Phosphorus plays an essential role in how the body stores and uses energy, it aids in the process of energy extraction by stimulating the process of metabolism of different nutrients including niacin(B3) and riboflavin(B2), helping to maximise the uptake of these two vitamins in particular.  The best sources for this mineral are chlorella, dairy, whole grains, legumes and nuts.

Phosphorus contributes to:

·         the maintenance of normal bones

·         the maintenance of normal teeth

·         the normal growth and development of bone in children

·         the normal function of cell membranes

·         normal energy-yielding metabolism

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

An essential trace mineral in the body, copper has long been known to play a role in human health – its use dates back to 400 BC when Hippocrates is said to have employed it as a treatment for a variety of disorders.  Playing a beneficial role in immune function, you need copper for healthy white blood cells – the cell type tasked with seeking out, identifying and destroying pathogens.  Low copper levels lower your white blood count leaving you vulnerable to infection. 

Copper is a vital element of the dark pigment melanin which imparts colouration to the hair and skin, intake of copper is said to protect greying hair.  Copper helps in the absorption of iron from the intestinal tract and releases it from its primary storage sites like the liver.  Also playing a significant role in the synthesis of haemoglobin, myelin and collagen, copper helps to protect the myelin sheath surrounding the nerves and is actively involved in the production of an element of connective tissue, elastin.  Functioning as a coenzyme for energy metabolism from the macronutrients in food we consume, copper enables a normal metabolic process in association with amino acids and vitamins.  Oxidative stress is a characteristic of copper deficiency, when obtained from dietary sources it acts as an antioxidant, getting rid of free radicals which can damage your cells and DNA.  For your body to use copper you need to have a balance of zinc and manganese which is why it is best to obtain your copper from dietary sources where it is already in bioavailable form.  Topping the chart as the best source of copper are oysters!  Closely followed by kale, shitake mushrooms, seeds, nuts and nut butters.

Copper Contributes to:

·         the maintenance of normal connective tissues

·         normal energy-yielding metabolism

·         the normal functioning of the nervous system

·         normal hair pigmentation

·         normal iron transport in the body

·         normal skin pigmentation

·         the normal function of the immune system

·         the protection of cells from oxidative stress

Selenium is an essential trace element that plays an important role in a number of physiological processes in humans.  It is a key element in spermatogenesis (the production or development of mature spermatozoa) and male fertility.  Selenium has also been shown to support the immune system by promoting the production of killer T-cells (a type of white blood cell), which engulf and destroy harmful foreign substances that enter the body and could otherwise cause disease and infection.  Selenium works in close conjunction with vitamin E as an antioxidant to prevent the formation of free radicals which can weaken and damage cells in every organ system. 

In addition, research has shown that selenium is an essential component of the thyroid gland’s functions, helping to regulate the amount of the thyroid hormone T3 that is produced within the body – without selenium the T3 hormone cannot be produced which can be catastrophic to a wide variety of your body’s systems.  It is believed that good selenium intake can help to prevent hair loss and promote shiny hair and healthy nail growth.  Brazil nuts are the richest source of selenium discovered so far, also found in mushrooms, shellfish, garlic, pumpkin and sunflower seeds, selenium is destroyed when foods are refined or processed so eating a variety of whole, unprocessed foods is the best way to get selenium into your diet.

Selenium contributes to:

·         normal spermatogenesis

·         the maintenance of normal hair

·         the maintenance of normal nails

·         the normal function of the immune system

·         normal thyroid function

·         the protection of cells from oxidative stress

Proteins are a group of biological compounds which are present in every live cell, organ and tissue of the body.  Meaning “first” or “of prime importance” in Greek, proteins participate in every cellular process occurring in the body.  Proteins are made up of structures called amino acids, there are a total of 21 amino acids, 9 are essential, the rest are nonessential – you must consume the essential amino acids in your diet because your body cannot make them. 

Dietary protein supports bone health in three main ways: by supplying the raw material required to construct soft bone matrix, by increasing plasma IGF1 and by promoting muscle growth and retention.  IGF1 is a growth hormone that stimulates and increases the activity of osteoblasts (cells which secrete the substance of bone).  It is especially important to ensure that children get enough protein since they are still developing and it is necessary to ensure their growth is unimpaired.  Proteins play an important role in muscle contraction and coordination, they are present in the muscle tissues in the form of many microfilaments and provide muscle structure.  Muscle growth depends on the adequacy of proteins in the body.  Proteins function as building blocks for muscles, bones and cartilage, opt for a variety of whole foods to meet your protein needs including; grass fed meat and poultry, eggs, dairy, seeds, beans and nuts.

Protein contributes to:

·         the maintenance of normal bones

·         a growth in muscle mass

·         the maintenance of muscle mass

·         Protein is needed for normal growth and development of bone in children.

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
