Nutrition is the process through which an organism obtains sustenance, or the supply of nutrients needed by its body and cells to survive. Nutrition is classified into two types: autotrophic nutrition and heterotrophic nutrition. Autotrophic nourishment is used by plants.

There are many types of nutrition

About 40 different types of nutrients may be found in food, and they can be generally grouped into the seven main classes mentioned below.

  • Carbohydrates
  • Proteins
  • Fats
  • Vitamins
  • Minerals
  • Dietary fiber
  • Water

1) Carbohydrates

Carbohydrates, sometimes known as carbohydrates, are sugar molecules. One of the three fundamental nutrients found in foods and beverages, together with proteins and lipids, are carbohydrates. Your body transforms carbohydrates into glucose. The majority of the energy used by your body’s cells, tissues, and organs comes from glucose, sometimes referred to as blood sugar..


Types of Carbohydrates

Starches (sometimes referred to as complex carbs)



Starch is a polysaccharide (C6H10O5)n composed of several glucose monomers linked together by glycosidic linkages. It is most common in seeds, bulbs, and tubers. It is a carbohydrate, which is an organic substance composed of carbon.


A natural polymer, also known as a polysaccharide, or long chain of just one type of molecule, is starch.. Starch is made up of glucose molecules. There are two types of it: amylose and amylopectin.

example of sugar

Brown sugar, corn sweetener, corn syrup, dextrose, fructose, glucose, high-fructose corn syrup, honey, invert sugar, lactose, malt syrup, maltose, molasses, raw sugar, sucrose, trehalas, turbinado sugar, anhydrous dextrose, and confectioner’s powdered are some examples of added sugars that may be listed as an ingredient.


Roughage or bulk, another name for dietary fibre, refers to the components of plant meals that your body cannot digest or absorb. Fibre isn’t processed by your body like other meal ingredients like lipids, proteins, or carbs that it breaks down and absorbs.

What does fiber do for the body?

encourages a healthy, diversified gut microbiota.
encourages typical bowel motions.
prolongs the period during which you feel full.
aids in lowering high blood pressure.
keeps cholesterol levels in check.
minimizes blood sugar increases.
connected to a reduced risk of various illnesses.

2) Proteins

Living things include chemical molecules called proteins. They carry out a variety of functions, including administration, transportation, and defence. A protein is made up of chains of amino acids and can have up to four distinct structural levels.The tissues of animals and some plants contain fatty substances.On the basis of their chemical compositions, scientists classify minerals.



collagen, insulin, and manticores.

3) Fats


Animal and certain plant tissues contain oily compounds called fats. These fats are present in many of the foods we eat. Animal products like milk, eggs, and meat all have fats in them.

Functions of Fat in Food

Transfer of Heat.
breaking point.

4) Vitamins


Vitamins are a class of nutrients required for healthy cell growth, development, and function.

There are thirteen necessary vitamins. This indicates that the body needs certain vitamins to function effectively. As follows:

vitamins A and C.
Nutrition D
vitamins E and K.
Thiamine, a vitamin B1,
B2 (riboflavin) vitamin
Niacin, vitamin B3,
B6 (pyridoxine) vitamin
The B12 vitamin, cyanocobalamin
B5 pantothenic acid
B7 biotin
(B9 or folic acid) Folate

5) Minerals


The fundamental components of our world are minerals. Find out what they can tell us about Earth’s past and the history of our solar system, as well as why they are so vital to our existence.

Scientists categories minerals based on their chemical makeup.. Native Elements, Sulphides, Sulphides, Halides, Oxides, Carbonates, Phosphates, Silicates, and Organic Minerals were the first nine mineral classes classified in the Dana Classification System.

6) Dietary fiber

Dietary fibre is the portion of plant material in the diet that is resistant to digestion, and it is made up of cellulose, noncellulosic polysaccharides including hemicellulose, pectic compounds, gums, mucilage, and the non-carbohydrate lignin. Among its many advantages are its ability to control weight, avoid constipation, improve gut health, lower the risk of heart disease, and type 2 diabetes. enzymatic digestion.

Why do we need dietary fiber?

For several reasons, the body need dietary fiber. Its capacity to manage weight, prevent constipation, enhance gut health, lessen the risk of heart disease and type 2 diabetes are just a few of its numerous benefits.

7) water


Two hydrogen atoms and one oxygen atom make up the substance known as water (H2O), which can exist in one of three states: as ice-like and as gaseous as water vapor, and liquid as water. The physical and chemical characteristics of water are essential for ecosystem survival.

Characteristics of water

Water is polar and an excellent solvent..
Water can withstand a lot of heat.
Water vaporizes at a high temperature.
The cohesive and adhesive qualities of water.
As a solid, water is less dense than as a liquid.

Why it’s important

Most individuals are aware that a healthy diet and regular exercise can help them maintain their weight.. However, the advantages of healthy eating go beyond weight loss. Nutritional health can:

Reduce the likelihood of developing certain diseases, such as osteoporosis, heart disease, diabetes, stroke, and certain malignancies
Lower your blood pressure

decreasing high cholesterol
Enhance your health Enhance your resistance to disease Enhance your capacity to recover from sickness or injury Increase your level of energy.

What is nutrition, and why does it matter?


Calcium is required by the body to build bones and teeth. It also promotes a healthy neurological system, heart, and other systems.

Too little might weaken teeth and bones. Tingling in the fingers and potentially fatal alterations in cardiac rhythm are signs of a severe deficit.

Constipation, kidney stones, and poor mineral absorption might all result from consuming too much.

According to current recommendations, individuals should take 1,000 mg daily, and women over the age of 51 should take 1,200 mg.

Dairy foods, tofu, lentils, and green, leafy vegetables are all excellent sources.


All body cells contain phosphorus, which also helps to maintain the strength of the bones and teeth.

Bone problems, changes in appetite, weakened muscles, and poor coordination can all result from a phosphorus deficiency. Additionally, it may cause anemia, an increased risk of infection, scorching or prickling skin, and disorientation.

Though toxicity from supplements, drugs, and issues with phosphorus metabolism is conceivable, eating too much is unlikely to result in health issues.

Adults should try to get 700 mg of phosphorus daily from a dependable source. Dairy products, salmon, lentils, and cashews are all excellent suppliers.


Magnesium supports healthy muscle and neuron function. It assists the body to make proteins, bone, and DNA, and it aids in controlling blood pressure and blood sugar levels.

Magnesium deficiency can eventually cause symptoms such as fatigue, restlessness, weakness, nausea, and sleep disorders.

Too much can cause issues with the digestive system and, eventually, the heart.

Among the best sources of magnesium include nuts, spinach, and beans. Adult males require 420 mg of magnesium daily, whereas adult females require 320 mg.


The immune system, the development of proteins, wound healing, and the health of bodily cells are all impacted by zinc.

Too little can cause diarrhoea, taste or smell changes, skin sores, hair loss, and other unusual side effects.

Too much might cause headaches and stomach issues. To find out more, click here.

Adult males require 11 mg of zinc daily, whereas adult females require 8 mg. Oysters, meat, fortified breakfast cereals, and baked beans are dietary sources.


Iron is essential for the synthesized blood cells, which transport oxygen to every area of the body, come from a reliable source. In addition, it contributes to the production of hormones and connective tissue.

Anemia, which can cause problems with digestion, weakness, and difficulties thinking, can be brought on by too little. Find out more about iron deficiency here.

Having too much can cause stomach issues, and having too much might be deadly.

Fortified cereals, cow liver, lentils, spinach, and tofu are other excellent sources. Adults require 8 mg of iron daily, whereas females throughout their reproductive years require 18 mg.


Manganese is used by the body to make energy. It helps the immune system and aids in blood coagulation, according to a reliable source.

A lack of it can lead to mood swings in women, skin rashes in males, and weak bones in young infants.

Only at extremely high doses may too much cause tremors, muscular spasms, and other symptoms.

Manganese may be found in mussels, hazelnuts, brown rice, chickpeas, and spinach. Adult males require 2.3 mg of manganese daily, whereas adult females require 1.8 mg.


Body benefits from copperTrusted Source creates connective tissues, blood arteries, and energy.

Fatigue, pale skin patches, elevated cholesterol, and connective tissue diseases can all result from a copper deficiency. This is unusual.

A copper overload can harm the liver and cause diarrheic, nausea, and stomach discomfort. Copper overload also hinders zinc absorption.

Beef liver, oysters, potatoes, mushrooms, sesame seeds, and sunflower seeds are among the excellent sources. Adults need 900 micrograms (mcg) of copper each day.


It is an electrolyte, potassium. It makes it possible for the kidneys, heart, muscles, and nerves to function properly. According to the 2015-2020 Dietary Guidelines for Americans, people should have 4,700 milligrams (mg) of potassium daily.

Kidney stones, high blood pressure, and stroke can all result from eating too little.

For those with renal illness, too much might be dangerous.

Avocados, coconut water, bananas, dried fruit, squash, beans, and lentils are all excellent sources.


As an electrolyte, sodium aids:

sustain muscle and nerve activity
control the body’s fluid levels
A low amount might cause hyponatremia. Lethargy, disorientation, and exhaustion are among the symptoms. Discover more here.

When consumed in excess, it can raise blood pressure, which raises the risk of heart attack and stroke.

Sodium and chloride are the two ingredients that make up table salt, a common condiment. Despite this, the majority of individuals ingest too much salt since it comes naturally in most meals.

Experts advise against consuming additional table salt. Currently, it is advised to limit your daily salt intake to 2,300 mg, or around one teaspoon.

This advice covers salt that is obtained naturally as well as salt that is added to meals.


What are the 6 essential nutrients?

Essential nutrients are necessary for a person’s development, health, and capacity for reproduction. This list of essential nutrients includes both macronutrients and micronutrients.

A human need micronutrients in modest amounts. Minerals and vitamins make up micronutrients. Even though the body only requires trace amounts of these, a shortage might have negative health effects.

A person need more of the nutrients known as macronutrients. Water, protein, carbs, and lipids are examples of macronutrients.
