Micronutrients are nutrients required by the body in lesser amounts, but are still essential for carrying out bodily functions. Micronutrients include all the essential minerals and vitamins. There are sixteen essential minerals and thirteen vitamins.
In contrast to carbohydrates, lipids, and proteins, micro-nutrients are not directly used for making energy, but they assist in the process as being part of enzymes (i.e., co-enzymes). Enzymes are proteins that catalyze chemical reactions in the body and are involved in all aspects of body functions from producing energy, to digesting nutrients, to building macro-molecules. Micro nutrients play many roles in the body. It classified into two parts as figure shown below:
The 13 vitamins are categorized as either water soluble or fat soluble. Water soluble vitamins are carried to the body’s tissues but are not stored in the body. The water soluble vitamins are vitamin C and all the B vitamins, which include thiamine, riboﬂavin, niacin, biotin and folate. The fat soluble vitamins are A, D, E, and K dissolve in fat and are stored in fat throughout the body. Vitamins are required to perform many functions in the body such as making red blood cells, synthesizing bone tissue, and playing a role in normal vision, nervous system function, and immune system function. Vitamin deﬁciencies can cause severe health problems.
Following below the table indicates the list of all the Vitamins with their role played in the human body along with dosage per day required & its food sources as:
Minerals are solid inorganic substances that form crystals and are classiﬁed depending on how much of them we need. Trace minerals, such as
• Iodine etc.
are only required in a few milligrams or less Macro minerals, such as
are required in hundreds of milligrams. Many minerals are critical for enzyme function, others are used to maintain ﬂuid balance, build bone tissue, synthesize hormones, transmit nerve impulses, contract and relax muscles, and protect against harmful free radicals.
