Magnesium
Which foods contain magnesium?Magnesium is a macro mineral, which means that it is needed by the body in large amounts so eating magnesium rich foods is important. Calcium, Sodium and Potassium are also macro minerals. The average human body contains approximately 25 g of magnesium, and it is one of the most important minerals that must be supplied in the diet.
What is magnesium?
Magnesium is one of the essential minerals that we need in order to stay healthy. It is an inorganic element that comes from the earth. In nature it is found in many different forms, including as magnesium chloride (one of the salts in seawater) and Magnesite, an insoluble rock salt also known as magnesium carbonate. In plants, it is the central element in the green pigment chlorophyll, and therefore is found in all plants to varying degrees. However this does not necessarily mean that green plants are the best source of magnesium.
Magnesium is needed for more than 300 biochemical reactions in the body. It helps regulate blood glucose levels, supports a healthy immune system and helps to maintain normal nerve and muscle function. It also helps in the production of energy and proteins. While it is important to ensure you eat sufficient magnesium rich foods, the body removes any excess magnesium so it is unlikely you will take in too much of this mineral.
