Water makes up 45-75% of our body and is required for the smooth functioning of our body. Water involves several body processes and helps to manage our temperature. Blood and different body fluids are mainly composed of water, which are required to maintain nutrients in our internal system and around cells. It is advised to drink 8-10 cups of water every day to fulfil our body's water requirements.

Carbohydrates are found in many food ingredients. Carbohydrates are created by atoms, including carbon, oxygen and hydrogen. They are a main source of energy for body cells. When we eat carbohydrate-rich food items, it easily gets digested and easily breaks down to release energy within the different cells of our body.

Carbohydrates break into glucose molecules, which are released into the bloodstream. The excess amounts of glucose molecules get stored in the liver.

Carbohydrates have many varieties of sugar units, including:

Monosaccharides (aldohexose and fructose)
Disaccharides (saccharose and lactose)
Oligosaccharides
Polysaccharides units (starch, glycogen, and cellulose).
Carbohydrate compounds:

Sugars: A simple structure made up of glucose molecules. It easily gets dissolved in water.
Starch: Complex in structure, less sweet compared to sugars.
Fibre: Fibers have a complex structure and take time to break down.

Fats substances are made up of ester of fatty acids. Fats are generally obtained from plant and animal sources. Fats with high energy give more calories and also take more time to digest.

Fats are the source for composing and maintenance of regular cell membranes of the body. They are also needed for maintaining the health of skin and hair. The fatty acid that the body cannot manufacture and have to get from a proper diet are called essential fatty acids. For example, Alpha-linolenic acid (Omega -3 fatty acids).

Proteins are composed of amino acids that are required for the build of our tissues. The proteins in our regular diet help the growth, repair, and also maintenance of body tissues. The body can convert proteins to glucose to regulate blood glucose levels to meet the required energy levels.

Proteins are available in different quantities in different foods, including dairy, poultry, seafood, meat, beans, peas, nuts, seeds, products, and other dairy products.

Proteins are organic compounds that include amino acids joined by amide bonds. The body does not synthesise the essential amino acids. 


Amino acids are organic compounds that consist of nitrogen, carbon, hydrogen, and oxygen atoms. Our body desires twenty different amino acids to grow and perform properly. At the same time, all twenty of those are vital for your health.

Out of 20, there are 9 essential amino acids; each of them performs a variety of vital jobs in your body. These amino acids are as follows:

I) Phenylalanine

Your body turns this aminoalkanoic acid into the neurotransmitters aminoalkanoic acid, dopamine, epinephrine, and noradrenaline. Phenylalanine plays an integral role in the performance of proteins and enzymes and also the production of alternative amino acids.

ii) Valine

Three branched-chain amino acids mean branching far from one aspect of its molecular structure. Valine is a supporting source to stimulate muscle growth and the regeneration process associated with energy production.

iii) Threonine

Threonine is the principal part of structural proteins, like scleroprotein and albuminoid. It conjointly plays a task in metabolism and immune operation.

iv) Tryptophan

Tryptophan essential amino acid could be a precursor to monoamine neurotransmitters. This neurochemical regulates your appetite, sleep, and mood.

V) Methionine

Methionine acid plays a crucial role in metabolism and detoxification. It's conjointly necessary for tissue growth and also for the absorption of metal.

VI) Leucine

Leucine is important for supermolecule synthesis and muscle repair. It conjointly helps regulate blood glucose levels, stimulates wound healing, and produces growth hormones.

VII) Isoleucine

Isoleucine essential amino acid is concerned with muscle metabolism and is heavily targeted in muscle tissue. It's conjointly vital for immune operation, Hb production, and energy regulation

VIII) Lysine

The essential amino acid plays a major role in supermolecule synthesis, metallic element absorption, and also in the production of hormones and enzymes. It's jointly vital for energy production, immune function, and also the production of scleroprotein and albuminoid.

IX) Histidine

The human body uses histidine to give neurochemicals that are very useful to immunologic responses, proper digestion, sexual activity, and maintaining sleep cycles. Histidine is also required for protecting barriers that surround your entire nerve cells.

Micronutrients
Micronutrients support the body's metabolism. Dietary minerals typically are trace parts, salts, or ions like copper and iron. Several minerals are required to regular human metabolism.

Vitamins are composed of organic compounds required for the body. They sometimes act as coenzymes or cofactors for numerous proteins within the body.

Small amounts of vitamins are essential for our body to function smoothly. Every nutrient works as a part of a distinct method in our body and serves to build our metabolism, growth and development.

Vitamins are mainly classified into 2 main categories

Water-soluble vitamins:

B compound vitamins and vitamin C.
Fat-soluble vitamins:

Fat-soluble Vitamins are mainly A, D, E, & K.

Minerals are those elements that are essential for our body. Some minerals are required for metabolic processes, where few minerals are major components of body structures, like the major proportion of calcium in our bone structures and teeth. Like vitamins, different foods contain different minerals.

The seven essential plant nutrients outlined as micronutrients are listed below:

Boron (B)
Zinc (Zn)
Mn (Mn)
iron (Fe)
copper (Cu)
Manganese (Mo)
Chlorine (Cl)
Conclusion
Nutrients themselves give better health and tend to reduce metabolic illness. At the same time, the immunity provided by the nutrients protects the body from microorganisms like a virus, bacteria, fungs, and other protozoans. So, maintaining a good diet is more important for every human being.
