Before we look at the blood itself let us look at a simplified description of a cell.

Before we look at the blood itself let us look at a simplified description of a cell. It contains a wall, plasma and a nucleus; It is the nucleus that gives the cell its life or its activity. Remove the nucleus and the cell becomes inactive or dies. Our bodies are made up of trillions of individual cells of varying types that come together to form the organs, systems and tissues. Each cell contains a nucleus that determines how effectively it will function. For the nucleus to function effectively it requires two substances: air and food. How then does the nucleus obtain these two essential ingredients? Through the blood which circulates and reaches every single cell in our bodies. This service is essential - so much so that a body region deprived of circulation dies in a matter of minutes.

Now that we have established that the health of the cell, and in particular the nucleus within the heart of that cell is the center or foundation to the health of our entire body, how do we make sure that this vital aspect of who we are is kept functioning at its optimum level? It is the blood which nourishes and cleanses the cell to keep it alive and well. When the blood passes through the lungs, the red blood cells become loaded with oxygen (air) and that same blood passes by the small intestines where nutrients pass by osmosis into the blood stream.  The blood, loaded with oxygen and nutrients, circulates and feeds every single cell in our bodies. It should then go without saying that it is important to make sure that the air and the nutrients provided for circulation to our cells be of the best possible quality.

Most of the time we do not have much control over the air we breath, but even here there are areas in which we can make choices. The obvious one being; is smoking good for my health? Many who smoke, do so to calm their nerves not being aware that the very act of smoking decreases the vitality of the very nerves they intend to calm making them even more stressed, which demands more smoke in an endless spiral.

A healthy diet should include as extensive a variety of foods as possible. There are various elements in food that are essential to good health; fats, vitamins, minerals, enzymes, proteins (essential amino acids) and water.


Saturated fats should be kept to a minimum, however a good diet will be high in essential fatty acids, or monounsaturated and polyunsaturated fats. EFAs are essential to the absorption of vitamins A, D, E and K which are all fat-soluble vitamins. Monounsaturated fats are found in nuts, olive oil and avocados. Polyunsaturated fats are found in fish (as omega 3) nuts and seeds.


The function of vitamins are as regulators of body chemistry or metabolism. They are necessary for normal synthesis and breakdown of body carbohydrates, fats, and proteins. Many play a role as coenzymes.  Vitamins are found in fruit, vegetables and meat.


Because they are an important part of bones, some elements (calcium and phosphorus) contribute to body structure. Iron is a part of haemoglobin, the red pigment in blood that transports oxygen from the lungs to the cells. Minerals in body fluids help in maintaining our acid-alkaline balance and water balance. Some of the minerals are essential for normal responses of nerves and muscles to stimuli. Certain minerals are important regulators of body chemistry and are essential for normal enzyme action. Water accounts for 80% of our body weight and water is a constituent of every cell in the body. Blood, a water solution, carries nutrients to cells and waste products from them.  Minerals are found mostly in vegetables, especially dark green leafy vegetables.  Sea vegetables being the most complete in minerals and contain high quality protein as well.


Enzymes are the spark of life! They are responsible for thousands of metabolic processes that sustain life. Enzymes are highly selective catalysis, they accelerate both the rate and specific way the body metabolizes, from the digestion of food to the synthesis of DNA. Without enzymes metabolism would be impossible. Enzymes are found in a great variety of foods but the greatest concentration is found in fruit. Examples of enzymes are papain, found in papaya and bromelain in pineapple.


The primary function of protein is growth and maintenance of muscles or lean body tissues. Proteins are made up of smaller components, amino acids, nine of which are essential; that is, they must come from food sources because the body cannot synthesis them.

In the choice of foods available to us there is a wide range of possibilities. There are as many choices that are detrimental to our health as those that are good for it. However, the quantity of food we ingest is equally important to consider. Eating a small amount of good quality red meat for instance is packed with proteins, vitamins, minerals and enzymes but taken in excess this super food becomes toxic, it is up to us to choose how much we will consume.

Choose wisely.
