Last week we had a question from a Mum who wanted to know why there was copper in our baby formula. She thought it was strange until we explained that copper is in fact an essential element, vital to the proper functioning of the body. We started thinking that maybe we should write a review on vitamins and minerals to get the facts straight. This is the first of a two-part series and it focuses on minerals.
Antoine Lavoisier (1743-1794) is probably best known for the fact that he recognised the role of oxygen in combustion and named both oxygen and hydrogen. Not a bad start!
But he also discovered that the building blocks of proteins, fats and carbohydrates consist of the elements carbon, hydrogen and oxygen. His theories paved the way for future discoveries about the building blocks of cells. It was soon revealed that all organisms are built from the same six essential elemental ingredients: carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P) and sulfur (S).
Dietary minerals are the other chemical elements our bodies need, apart from carbon, hydrogen, oxygen and nitrogen. The term “minerals” is misleading, and would be more meaningful if they were referred to as “ions” or “dietary ions”. People who have a well balanced diet will, in most cases, obtain all their minerals from what they eat. Minerals are often artificially added to some foods to make up for potential dietary shortages and subsequent health problems. The best example of this is iodized salt – iodine is added to prevent iodine deficiency, which even today affects about two billion people and causes mental retardation and thyroid gland problems. Iodine deficiency remains a serious public health problem in over half the planet.
Approximately 4% of the human body consists of these “minerals”. An adult of 75kg contains about 3kg of minerals. Because your body cannot make minerals, they must come from your diet. Minerals are therefore essential nutrients. At least 16 of them are considered crucial in our diet. They are all essential to life; without them you wouldn’t be able to function properly, grow or procreate.
The interesting thing is that while they are essential to life in minute quantities, all of these substances are toxic in large doses! This seemingly contradictory fact confuses a lot of people. Some research now suggests that trace amounts of arsenic are essential, too!
Minerals can be divided into two main categories, based on the amount that is needed by the body.
These are present in relatively large amounts in the body and are therefore required in fairly large amounts in the diet —more than 100 milligrams daily. Calcium is the most common and abundant mineral that accounts for approximately 2% of an adult body, so an average adult who weighs 75kg contains about 1.5kg of calcium.
Interestingly, calcium is closely linked to another macro-nutrient we don’t hear a lot about and that’s magnesium. It turns out that these two are almost yin and yang elements:
▪ Calcium exists mainly outside the cells, whereas almost all magnesium is found inside the cells;
▪ Calcium excites nerves; magnesium calms them down;
▪ Calcium with potassium makes muscles contract, but magnesium is necessary for muscles to relax;
▪ Calcium is necessary to the clotting reaction – essential for wound healing – but magnesium keeps the blood flowing freely and prevents abnormal thickening when clotting reactions would be dangerous.
Calcium is mostly found in the bones and gives them much of their hardness, whereas magnesium is found mainly in soft structures.
The balance of calcium and magnesium is very important and with so many women being told to take calcium to prevent osteoporosis, many may not have enough magnesium as a result. If you are taking additional calcium you might want to check with your health professional that your magnesium levels are not suffering.
Other macro-nutrients are sodium, potassium, phosphorus, chlorine (in the form of chloride ions) and sulphur.
Trace minerals are those that are required by the body in amounts of less than 100mg per day. Iodine is one of these. It’s probably because of it’s relative abundance in seawater that iodine came to play a key part in animal life. Interestingly it’s the heaviest element in the human body. (Well, the heaviest that’s supposed to be there, anyway!) But it accounts for a tiny fraction of us – only 0.0225 milligrams in your entire body. To put that another way, more than 40,000 people would only have a kilogram between them! Nevertheless it is absolutely essential because it enables the thyroid gland to produce thyroid hormones, essential to normal healthy growth.
Here is a list of the most critical chemical elements (“minerals”) needed by the body. Some authorities suggest there are more minerals, including vanadium, nickel, boron and arsenic, but that is not a widely held view at this point. The macro-nutrients are highlighted in bold italics.
Mineral & symbol | Function | Found in |
Calcium Ca | Builds teeth and bones. Controls heartbeat & blood pressure, regulates muscle contractions | Dairy products, salmon, green vegetables, soy |
Chlorine Cl(as the chloride ion, Cl– )) | Used to make hydrochloride acid in the stomach. Chloride is found in the fluid around all cells in the body | Table salt |
Chromium Cr | Chromium is important in the metabolism of fats and carbohydrates. Chromium stimulates fatty acid and cholesterol synthesis, which are important for brain function and other body processes. Chromium is also important in the metabolism of insulin. | Meat, liver, mushrooms and egg yolks |
Cobalt Co | An essential component of Vitamin B12 This vitamin helps prevent anaemia, fatigue and depression. | Vitamin B12 can only be manufactured by bacteria and can only be found naturally in animal products, however, synthetic forms are widely available and added to many foods like cereals |
Copper Cu | Required for blood clotting, but also found in many enzymes. Used in the development of bone and connective tissue | Prawns, beans and peas, nuts. Also found in liver. |
Iodine I | The main building block of thyroid hormones T3 & T4 important to growth and development | Found in iodine-enriched table salt because our diets don’t usually contain enough iodine and deficiency can be serious |
Iron Fe | The essential part of haemoglobin in blood. Facilitates the transport of oxygen around the body | Haem iron: Liver, kidneys, meats;Non-haem iron: oysters, the yolks of eggs, nuts and lentils |
Magnesium Mg | Stimulates enzyme activity in cells | Citrus fruits, green vegetables |
Manganese Mn | Activates many important enzymes, including the development of sex hormones and the formation of proteins | Cereals, vegetables, fruit and nuts |
Molybdenum Mo | Important to enzyme building and the metabolism of fatty acids | Brown rice, garlic, spinach |
Phosphorus P | Occurs as phosphates and found in DNA & RNA. Also involved in protein and fat metabolism | Meat fish and poultry, eggs, nuts, seeds and cereals |
Potassium K | Works with sodium, see below | Tomatoes, bananas, green leaf vegetables, nuts, citrus fruits, fish |
Selenium Se | Works with vitamin E to protect cells from damage because it makes antioxidant enzymes. It has been shown to counteract the toxicity of heavy metals (lead mercury, cadmium etc) | Found in all protein foods |
Silicon Si | Important in the formation of tendons and ligaments | Root vegetables and whole grains |
Sodium Na | Works with potassium to regulate pressure within and between cells and to control the body’s water balance | Fish, bacon, crustaceans, table salt |
Zinc Zn | Over 200 enzymes rely on zinc to enable them to catalyse chemical reactions in the body | All meats, fish, wheat germ and vegetables |

If you are able, breastfeeding is best, as it provides the ideal nutrition for babies and has other important health benefits too. Health Professionals are well placed to provide appropriate feeding advice and support. A healthy diet during pregnancy and whilst breastfeeding is important.
Introducing infant formula either partially or exclusively, may reduce the supply of breast milk. Once reduced, it is difficult to re-establish. Social and financial implications, such as preparation requirements and cost of formula until 12 months, should be considered. When using infant formula, always follow the instructions for use carefully, unnecessary or improper use may make your baby unwell.
