Minerals are non essential nutrients and provide 4 kilocalories per gram true or false

False

Minerals are essential nutrients. In fact, there are 16 essential minerals: (copper, manganese, iodine, and selenium, molybdenum, chromium,  fluoride, calcium, phosphorus, potassium, sulfur, sodium, chloride, magnesium, iron, and zinc).

 Minerals which are also called micronutrients play important roles in the body such as:  maintain blood pressure, bone health and fluid & electrolyte balance, and make new cells; deliver oxygen to cells; and contribute to normal muscle and nerve functioning.  

The above statement is false.
