subject: Silicon - A Key Nutrient For Skeletal Development [print this page] Silicon is a micromineral which assists in the development of the connective tissues and skeletal system. It also supports healthy growth and numerous important functions throughout the body. In this article I will be discussing this nutrient in greater detail and providing you with a summary of its main functions, the best food sources, the recommended daily allowances (RDAs) and the potentially adverse effects of consuming too much or too little.
1) DISCOVERY:
Silicon was first discovered by the French chemist Antoine Lavoisier in 1787 when he identified it as part of silicate. However, he was unable to successfuly isolate silicon from silicate. The Swedish chemist Jons Jakob Berzelius managed to successfully isolate silicon in 1823.
2) FUNCTION:
The main role of silicon is to support the development and maintenance of both the connective tissues and skeletal system. It also supports the development of healthy bones, hair, nails and teeth and increases the effectiveness of the nutrients calcium, glucosamine and vitamin D. In addition to this, silicon prevents atherosclerosis (a condition where hard plaques form in the artery walls), alopecia (thinning hair) and skin conditions. Finally, this nutrient keeps your eyes and skin bright, regulates chemical reactions in the cell membranes, supports proper nerve function and helps the body's tissues heal.
3) RDA:
Silicon currently has no official RDA. However, research suggests that a daily intake of between 1 and 2 grams (g) is adequate. Most diets that incorporate natural fruits, herbs and vegetables will supply your body with adequate amounts of silicon.
4) FOOD SOURCES:
Currently there is very little information published on the amounts of silicon in food but natural, plant based foods are the richest source. Some of the top food sources include almonds, apples, cabbage, oats, onions and oranges.
5) OVERDOSE SYMPTOMS:
There are currently no overdose symptoms associated with eating too much silicon. However, excessive inhalation of silicon dust can cause silicosis (a dangerous lung disease).
6) DEFICIENCY SYMPTOMS:
Most plant based foods contain silicon so deficiencies are extremely rare. In most cases silicon deficiencies only develop in individuals with an extremely limited diet. The symptoms of silicon deficiency include ageing of the skin, brittle nails, an increased sensitivity to cold temperatures, poor bone development, thinning hair and wrinkled skin.
7) SUMMARY:
As you can see silicon is important throughout the body in both a preventative and supportive role. So make sure you incorporate some natural, plant based foods into your diet to ensure that your body gets all the silicon it needs.
