What are the 5 Main Nutrients and Their Functions?

List of Essential Main Nutrients

Classes of Nutrients and their Functions: It is one of life’s pleasures to enjoy food. When there is enough food available, eating is something additional than just surviving. Together eating is a significant aspect of social gatherings, festivals, and everyday family life.

Food sources are obviously necessary for living additionally for the enjoyment it offers. The quantity and variety of food that is available locally determines how the body will obtain the many classes of nutrients that it needs. Additionally, people have diverse food preferences and eating patterns, therefore this differs greatly around the globe. Various populations have varied nutritional requirements.

A nutritious diet can include any item as a component of it. An individual food item is neither nutritionally “excellent” nor “bad” on its own. What counts is how well a specific food complements or interacts with other foods to satisfy an individual’s or a person’s nutrient and energy demands. The best recommendation is to spread consumption out throughout the day and attempt to eat a variety of things.

This is crucial for kids since they can’t get the nourishment they need from just one or two meals. Breakfast is crucial since it supplies energy for both physical and mental activity. This course offers fundamental advice on a healthy diet, eating behaviours, lifestyle decisions, and food ethics to help you make the most of the food that is readily available. The supplied knowledge may help people avoid poor diet-related illnesses and poor health.

6 Essential Nutrients | List of Nutrients

Important Classes of Nutrients: Food gives us the energy we need for physical activity, growth, and basic bodily processes like breathing, thinking, controlling body temperature, blood circulation, and digestion, among other things. Additionally, food provides us with the building blocks needed to keep our bodies healthy and to strengthen our immune systems. Therefore, the nutrients found in food enable these many functions. The many classes of nutrients food are listed below.

1. Carbohydrates

2. Proteins  

3. Fats

4. Vitamins

5. Minerals

6. Water

One or more of these nutrients can be found in different amounts in all foods. Each nutrient type has a specific purpose:

Carbohydrates (Food Sources)

Sugars, starches, and dietary fibre are all types of carbohydrates. For the majority of people on earth, they are the main source of food and energy. The simple sugars (fructose, glucose, and galactose) are either monosaccharides or disaccharides (lactose, sucrose, and maltose). As complex carbohydrates or polysaccharides, starch, glycogen, and dietary fibre (including hemicellulose, cellulose, and pectin) are referred to. Some complex carbohydrates are not major sources of dietary energy because they cannot be digested by humans. These are commonly found in plant cell walls and are referred to as dietary fibre. Fiber is nevertheless a vital component of the diet despite being a minor provider of energy. It is crucial for maintaining the digestive system’s health and functionality.

Food Sources of Carbohydrates | sources of food nutrients

  • Rice
  • Maize
  • Wheat
  • Other Grains
  • Potatoes
  • Yams
  • Cassava

Important Carbohydrates

The most significant carbohydrate is glucose. It is necessary for proper brain operation. Additionally, it is the type of carbohydrate that gives people their energy. It is frequently referred to as blood sugar in mammals. Many fruit and vegetable juices naturally include glucose; however, this monosaccharide frequently joins forces with another to produce a disaccharide. For instance, sucrose, sometimes known as table sugar, is a disaccharide made up of one molecule of glucose and one molecule of fructose, the main sugar found in the majority of fruits. Only milk, including human milk, contains lactose, which is a mixture of glucose and galactose.

Maltose is a compound made up of two glucose units that is produced when starch is broken down. After being broken down and absorbed, simple carbohydrates are transformed into glucose, which can then be stored as glycogen (a type of glucose found in animals’ muscles and liver) or fat, or immediately consumed for energy. The lengthy chains of glucose molecules that make up complex carbohydrates can number in the hundreds. The starches are converted during digestion into simple sugars, which are subsequently absorbed and used in the same way as other sugars. Glycogen is also converted back to glucose when blood sugar levels drop, acting as a quick source of energy. For those who engage in physical activity, this process is particularly crucial.

Proteins (Food Sources)

Proteins are necessary for the synthesis and upkeep of muscle, blood, skin, bones, and other human tissues and organs. Energy can also be obtained from proteins. Amino acids, which are the body’s main building components, are used to make proteins. The amino acids that are formed when proteins are consumed and digested are then absorbed and utilized to create new tissues.

Protein is crucial for youngsters who are growing. The optimal balance of amino acids for growth is found in breast milk, hence women should be encouraged to breastfeed for as long as possible. It’s crucial to add enough protein-rich foods to children’s main diets when they wean themselves from the breast.

Food Sources of Proteins

  • Meat
  • Poultry
  • Fish
  • Beans Peas
  • Soya Beans
  • Groundnuts
  • Milk
  • Cheese
  • Yoghurt
  • Eggs

These frequently cost more than other foods. The body’s energy needs must be satisfied by other foods for the optimal results from these foods. If not, the protein’s amino acids will be converted to glucose for energy instead of being used to create new proteins and tissues. Eating more protein than necessary can be inefficient since extra protein will either be stored as fat in the body or broken down into glucose and used as energy.

Proteins Types

The human body uses roughly 20 distinct types of amino acids. To create various proteins, these can be combined in a wide range of ways. The body can produce the majority of these amino acids from carbohydrates and other amino acids. Nine amino acids, however, are unable to be produced by the body and must instead be found in the food we consume. These nine amino acids are referred to as “essential.” If the diet lacks an adequate supply of each of these essential amino acids, the body won’t be able to produce all the protein it requires or utilize all the protein that has been consumed.

The quantities of the amino acids needed by the human body vary among the many types of protein found in the foods we eat. The majority of the required amino acids are found in animal proteins, which include those found in meat, milk, fish, and eggs. Proteins in foods made from plants typically have fewer of one or more of these amino acids. However, it is feasible to consume all the necessary amino acids by combining various food kinds. This is crucial for the vegetarian community in particular. A balanced combination of amino acids can be obtained, for instance, by combining pulses or legumes (peas, beans, and lentils) with grains (maize, wheat, sorghum, and rice). 

Fat (Food Sources)

Dietary fat is a natural component of meats, milk, eggs, nuts, and other vegetable foods. It also includes butter, oils, cooking fats, and ghee. A nutrient-dense diet must contain fats. They are a concentrated form of energy that makes up the majority of an animal’s and some seeds’ energy reserves. Fats, commonly referred to as lipids, are vital elements of cell membranes and a source of energy. They are also required for the absorption and utilisation of various vitamins. Additionally, fat adds flavour and satisfaction to meals. Adults should get between 15% and 35% of their calories from fat, depending on their activity levels and dietary habits.

In order to lower their risk of heart disease, people are typically recommended to consume saturated fats in moderation (less than 10% of their total caloric consumption). More than twice as much food energy comes from fats and oils as it does from carbohydrates and proteins. A particularly effective technique to improve young children’s energy intake is to add fat in the form of oil to their food. This is crucial since kids frequently are unable to consume enough “bulky” foods to meet their energy requirements. Between 30 and 40 percent of a young child’s calories should come from fat.

  • Oils
  • Some Meat
  • Meat Products
  • Lard
  • Butter
  • Ghee
  • Margarine
  • Fish
  • Nuts
  • Soya Beans

Some Facts about Functions of Nutrients Including Fats and Oils

1. Triglycerides are the most popular type of dietary fat and oil. These are the lipid-like substances that are most prevalent. Other lipid kinds include phospholipids and steroids, but triglycerides make up around 95% of what we consume.

2. Triglycerides are a component of dietary fats and oils. You can see the fat in ghee, buffer milk, lard, and processed oils, as well as the fat found in milk, seeds, almonds, and other vegetable sources that cannot be seen (olives, palm fruit, avocadoes,). Oils are often liquid and fats are solid or semi-solid when cool (room temperature).

3. Triglycerides are made up chemically of three fatty acids bound to a molecule of glycerol. Fatty acids are composed of chains of carbon atoms joined by hydrogen atoms and ending in an acid group (COIH). The carbon chain can range in length from two to more than twenty. The fatty acid is referred described as “saturated” if there are two hydrogen atoms connected to each carbon atom (three on the terminal carbon atom). The fatty acid is considered “unsaturated” if part of the carbon atoms only has one hydrogen bonded. The term “monounsaturated” or “polyunsaturated” refers to the amount of unsaturated carbon atoms in the fatty acid.

4. In general, a triglyceride is more solid at room temperature the more saturated fatty acids there are in it. Chicken fat is less saturated than beef fat, and plant-based oils (such peanut oil, olive oil, and sunflower oil) have a higher percentage of unsaturated fatty acids.

5. Cholesterol is a necessary component of every cell in the body and performs several crucial tasks. The liver produces the majority of the cholesterol in the body, while other cells and diet also contribute to its production. Different types of cholesterol are transported in the blood, and high levels of some of these types can increase the risk of high blood pressure, heart disease, and stroke. Diet has an impact on the quantity and type of cholesterol produced and transported throughout the body. It is typically advised that no more than 10% of daily energy intake should come from saturated fats because high intakes of saturated fats can cause specific issues.

Vitamins and Minerals

Micronutrients are substances like vitamins and minerals. They are necessary for proper nutrition but in considerably smaller amounts than carbohydrate, protein, and fat. They support the body’s optimal functioning and maintenance. Numerous biological tissues also contain certain minerals; for instance, calcium and fluoride are found in bones and teeth, while iron is present in the blood.

Iron nutrition

Red blood cells (RBCs) are largely composed of iron, which is required for all of the body’s cells to function normally. The most common nutritional issue in the world is iron deficiency anaemia. It affects men and elderly women as well as children and women who are of childbearing age, especially during pregnancy. Lethargy (low work capacity), learning challenges, poor growth, and higher morbidity (disease) and maternal mortality, particularly during birth, are the results.

Meat, fowl, fish, liver, and other organ meats are the richest sources of iron. Legumes, dried fruits and dark-green vegetables also contain iron, although this iron is not as well absorbed by the body as that found in animal products. More iron can be absorbed and used when vitamin C consumption is increased in addition to iron from vegetables. 

Vitamin A | vitamin a fruits and vegetables

The body need vitamin A for the synthesis and maintenance of healthy tissues. especially the tissues of the respiratory and digestive systems, skin, eyes, and bones. It is crucial for the immune system to work properly as well. A lack of vitamin A can cause poor night vision, night blindness, serious eye lesions, and in some cases, lifelong blindness. This mostly happens to malnourished kids, especially ones who have measles and other diseases. A lack of vitamin A can also increase disease and infection-related mortality. Only foods of animal origin, including breast milk, eggs, liver, and many dairy products, naturally contain vitamin A. However, a pigment called carotenes that the body can transform into vitamin A is present in a lot of dark-colored fruits and vegetables. Vitamins in leafy greens vegetables, mangoes, vivid yellow, carrots, orange sweet potatoes, and papaya are a few examples of foods high in carotene.

Thiamin, Niacin, B. Folate, Pantothenic Acid, Riboflavin, B₁2 and Biotin  

These are a part of the vitamin B complex, as it is frequently referred as. The B-vitamins are essential for utilising fat, protein, and carbs to build and repair bodily tissues as well as for converting them into energy. Serious consequences from vitamin deficiency might include heart failure, paralysis, severe anaemia, mental confusion, muscular weakness digestive issues, nervous system abnormalities, cracked and scaly skin. 

Folate | best source of folate

Folate (folic acid, folacin) deficiency is a common cause of anaemia in women and young children. Folate is required to build healthy blood cells. Birth problems may result from a folate deficit during pregnancy. It’s crucial to have enough B vitamins each day. Dark green vegetables, groundnuts, beans, peas, grains, meat, fish, and eggs are foods high in B vitamins.

Most Vitamin C Rich Foods

Vitamin C is required for the production of collagen, the connective tissue that holds the body’s cells together, to boost dietary iron absorption, and to act as an antioxidant. Scurvy can result from a protracted vitamin C deficit. Scurvy can be fatal and has symptoms including bleeding gums and painful, swollen joints. Most vegetables, including potatoes, and most fruits, particularly citrus and guava, are good sources of vitamin C. Fresh fruit and vegetables should be consumed by both adults and children. Here below mentioned are the most vitamin c rich food Sources:

  • Citrus
  • Lemon
  • Kiwi
  • Grapefruit
  • Oranges
  • Strawberries
  • Tomatoes
  • Brussels Sprouts
  • Cabbage
  • Broccoli
  • Bell Peppers
  • White Potatoes
  • Cauliflower

Vitamin D (Food Sources)

Particularly crucial to the body’s utilisation of calcium is vitamin D. Fish oils, eggs, and milk all contain vitamin D, and the body also produces it when the skin is exposed to sunshine. Rickets, a disease that produces fragile and malformed bones in young children, can be caused by a lack of vitamin D.

Calcium and phosphorus (Deficiency Diseases and Food Sources)

For the upkeep of the body as well as for having strong, healthy bones and teeth, calcium and phosphorus are crucial. Calcium and phosphorus are both abundant in milk and dairy products.

Iodine (Deficiency Diseases and Food Sources)

Iodine is necessary for healthy development and growth. Mental retardation and goitre, which is an enlarged thyroid gland, can result from a diet low in iodine. Foods grown in iodine-rich soils and seafood both contain iodine. Steps should be taken to add iodine to the diet in places with low levels of iodine in the soil, typically by iodized salt.

Fortified Foods (Deficiency Diseases and Food Sources)

Some foods can also have vitamins and minerals added to them to boost their nutritional value overall or to replenish nutrients lost during preparation. Fortified foods are those that have extra vitamins and minerals added. To make iodized salt, for instance, iodine is routinely added to salt. B vitamins and iron are frequently added to bread, flour, and other cereal products in many nations, and vitamins A and D are frequently added to processed milk, dairy products, and various vegetable oil products.

Water | nutrient water

Water is essential for the body’s many processes, including the creation of cells and bodily fluids, chemical reactions, and the production of urine, which removes waste from the body. A sufficient intake of pure water must be maintained in order to replenish the water the body loses, especially during hot weather and physical exercise. When a person has vomiting, diarrhoea, or a fever, they may also get dehydrated (have an excessive loss of water).

Importance of Nutrients in Our Body

Nutrients are essential components of food that are necessary for the growth, development, and maintenance of our body. The importance of nutrients in our body can be broadly classified into the following categories:

  1. Energy Production: Carbohydrates, fats, and proteins are macronutrients that provide energy to our body. Carbohydrates are the primary source of energy, while fats provide long-term energy storage. Proteins are essential for muscle development and repair.
  2. Maintenance and Growth: Nutrients like vitamins, minerals, and proteins are necessary for the maintenance and growth of various body tissues. For example, calcium and vitamin D are essential for bone health, while iron is necessary for the formation of red blood cells.
  3. Immune System: Nutrients like vitamin C, vitamin E, and zinc are necessary for the proper functioning of the immune system. They help fight infections and diseases.
  4. Brain Function: Nutrients like omega-3 fatty acids, vitamin B12, and iron are essential for brain function. They help improve memory, focus, and concentration.
  5. Metabolism: Nutrients like vitamin B-complex and magnesium play a crucial role in metabolism, which is the process by which our body converts food into energy.

Overall, nutrients are essential for the proper functioning of our body. A balanced diet that includes a variety of nutrient-rich foods is necessary for maintaining good health and preventing nutrient deficiencies.

How are nutrients used by your body?

Nutrients are essential substances that your body needs to function properly. The way nutrients are used by your body depends on the specific type of nutrient. Here are some examples:

  1. Carbohydrates: Carbohydrates are the main source of energy for your body. When you eat carbohydrates, your body breaks them down into glucose, which is used as fuel for your cells. Any excess glucose is stored in the liver and muscles as glycogen, which can be used for energy when needed.
  2. Proteins: Proteins are used by your body to build and repair tissues. They are also important for the production of enzymes, hormones, and other molecules. When you eat protein, your body breaks it down into amino acids, which are used to build new proteins in your body.
  3. Fats: Fats are used by your body as a source of energy and for insulation and protection of your organs. They also help absorb fat-soluble vitamins. When you eat fat, your body breaks it down into fatty acids, which can be used for energy or stored in your adipose tissue.
  4. Vitamins and minerals: Vitamins and minerals are used by your body for a variety of functions. For example, vitamin C is used to produce collagen, a protein that is important for healthy skin, while iron is used to produce hemoglobin, a protein that carries oxygen in your blood.

In summary, nutrients are used by your body for energy, building and repairing tissues, producing hormones and enzymes, and for various other functions. A balanced diet that includes a variety of nutrient-rich foods is essential for ensuring that your body gets all the nutrients it needs to function properly.

How does your body use carbohydrates?

Carbohydrates are a macronutrient that provides energy for your body. When you consume carbohydrates, they are broken down into glucose, which is the primary source of fuel for your cells. Here’s how your body uses carbohydrates:

  1. Immediate Energy: Glucose is readily available to your body for immediate energy. Your body uses glucose to power many of its functions, including breathing, pumping blood, and moving your muscles.
  2. Stored Energy: If you consume more carbohydrates than your body needs for immediate energy, the excess glucose is stored in your liver and muscles as glycogen. Glycogen can be quickly broken down into glucose to provide energy when needed.
  3. Brain Function: Your brain relies on glucose as its primary source of energy. It cannot use other sources of fuel, such as fat or protein, to function properly. When glucose levels drop too low, you may experience difficulty concentrating, dizziness, or fatigue.
  4. Reducing Protein Breakdown: When your body doesn’t have enough glucose for energy, it can break down protein in your muscles and other tissues to create glucose. However, if you consume enough carbohydrates, your body won’t need to break down protein for energy.

Overall, carbohydrates are an essential source of energy for your body. It is recommended that carbohydrates make up about 45-65% of your daily caloric intake. It’s important to choose complex carbohydrates, such as whole grains, fruits, and vegetables, as they provide additional nutrients and are digested more slowly than simple carbohydrates, such as sugar and refined grains.

How does your body use Protein?

Protein is a macronutrient that is essential for building and repairing tissues in your body. Here’s how your body uses protein:

  1. Tissue Repair and Growth: Protein is necessary for repairing and building tissues in your body. Your body uses protein to build and repair muscles, bones, skin, hair, and other tissues.
  2. Enzyme and Hormone Production: Proteins are used to make enzymes, which are catalysts that help to speed up chemical reactions in your body. They are also used to produce hormones, which regulate various bodily functions.
  3. Immune System Function: Many proteins play a vital role in your immune system. They help to fight off infections and diseases by recognizing and destroying foreign invaders like bacteria and viruses.
  4. Energy Production: In the absence of carbohydrates and fats, protein can be used by your body as an energy source. However, this is not the preferred use of protein and can lead to the breakdown of muscle tissue.
  5. Transport of Molecules: Some proteins act as carriers, transporting molecules such as oxygen and nutrients throughout your body.

Overall, protein is essential for the proper functioning of your body. It is important to consume enough protein in your diet to support tissue repair and growth, as well as other bodily functions. Good sources of protein include meat, fish, eggs, dairy, legumes, and nuts.

How can we sustain nutrients in our body?

Maintaining a balanced and healthy diet is the key to sustaining nutrients in your body. Here are some tips for sustaining nutrients:

  1. Eat a variety of foods: Eating a variety of foods ensures that you are getting a wide range of nutrients. Include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats in your diet.
  2. Avoid processed foods: Processed foods are often high in calories, sugar, and unhealthy fats and are often low in essential nutrients. Instead, focus on whole, nutrient-dense foods.
  3. Don’t skip meals: Skipping meals can lead to nutrient deficiencies. Make sure to eat regularly throughout the day, with a focus on balanced meals and snacks.
  4. Cook foods properly: Overcooking can lead to a loss of nutrients in your food. Cook your food using methods that preserve nutrients, such as steaming, roasting, or grilling.
  5. Consider taking supplements: While it’s best to get your nutrients from food, taking supplements can be helpful in ensuring you are meeting your nutrient needs. Talk to your doctor or a registered dietitian before starting any supplements.
  6. Stay hydrated: Drinking enough water is important for the absorption and transportation of nutrients in your body.
