Both vitamins and minerals are essential in the diet in small quantities. Learn about the two main vitamin groups and the major mineral elements. This free course, Nutrition: vitamins and minerals, looks at the two main groups of vitamins: the fat-soluble vitamins, A, D, E and K; and the water-soluble vitamins, the B group and vitamin C. It also examines the major mineral elements, and the importance of fluid balance in the body.
After studying this course you should know:
- that certain minerals are required in the body and that some minerals form essential structural components of tissues;
- that sodium, potassium, calcium and chloride ions are important in maintaining the correct composition of cells and of the tissue fluids around them (homeostasis);
- that some minerals are essential components of important molecules such as hormones and enzymes;
- that the correct fluid balance is essential for normal functioning of the body;
- that tapwater, and not just mineral water, contains minerals.

Nutrition: vitamins and minerals
Both vitamins and minerals are essential in the diet in small quantities.The term ‘vitamin’ was not coined until early in the 20th century, to describe those chemicals in food without which a pattern of deficiency symptoms (often called a deficiency syndrome) occurs. Minerals, also called mineral elements, are those elements other than carbon, hydrogen, oxygen and nitrogen that are found in the body.
This free course, Nutrition: Vitamins and minerals, looks at the two main groups of vitamins: the fat-soluble vitamins A, D, E and K, and the water-soluble vitamins, those of the B group (numbered B1, B2, etc.) and vitamin C. It also examines the major mineral elements, and the importance of fluid balance in the body.
