Nutrition is the study of mineral fibers and the connection between diet, health, and disease. To understand how fibers affect the human body, nutritionists use information from microscopic fields of natural science, biochemistry, and a person’s family tree. Nutrition also focuses on how the public can use digestive choices to reduce the risk of disease, what happens if one has too much or too little fiber, and how allergies work. Nutrient supply for Proteins, carbohydrates, fat, vitamins, minerals, texture, and water are all vitamins. If people do not have the right balance of foods in their diets, their risk of cultivating strong environments increases. This article will analyze the various foods and importance of nutrition according to the person need. It will likewise examine the roles of the dietitian and the nutritionist.

Your body relies on the energy exchanged from the food and drinks you consume. The main nutrients that the body uses for energy are carbohydrates, fats and proteins. Good carbohydrates are found in foods such as whole grain bread and starchy vegetables such as potatoes. These foods are digested slowly and thus provide longer lasting energy. Water is also necessary to carry nutrients throughout the body. Dehydration can lead to lack of energy.

3.What you eat affects your mood

Types of nutrition

types of nutrition

Two types of nutrients



Macronutrients are nutrients that humans require in relatively large amounts.


Sugar, starch, and fiber are types of carbohydrates. Sugar is a simple carbohydrate. Sugars and modified starches are quickly broken down and absorbed by the body. They can provide instant energy but won’t leave you feeling full. It can also cause an increase in blood sugar levels. Frequent sugar spikes increase the risk of type 2 diabetes and its complications. Dietary fiber is also a carbohydrate. The body breaks down certain fibers and uses them for energy. Other types pass through the body, while others are metabolized by intestinal bacteria. Carbohydrate have a great importance in the balanced nutrition.

Fiber and raw starch are complex carbohydrates. It takes time for your body to break down and absorb complex carbohydrates. People feel fuller longer after eating fiber. Dietary fiber may also reduce the risk of diabetes, cardiovascular disease and colon cancer. Complex carbs are a healthier choice than sugar and refined carbs.


Proteins are made up of naturally occurring organic compounds, amino acids. 20 kinds of amino acids. Some of these are essential and people must get them from food. Some amino acids have great importance in the balanced nutrition that are formed by the human body. There are some foods that provide complete protein. That means it contains all the essential amino acids your body needs. Different foods contain different combinations of amino acids. Since most plant-based foods do not contain complete protein, those on a vegan diet need to consume a variety of foods throughout the day that provide essential amino acids.


Fat is important for:

  • lubricate the joints
  • help organs produce hormones
  • so that the body can absorb certain vitamins
  • reduce inflammation
  • maintain brain health
  • Too much fat can lead to obesity, high cholesterol, liver disease, and other health problems.

However, the type of fat a person eats makes a difference. Unsaturated fats, like olive oil, are generally healthier than animal-derived saturated fats.


An adult human body is 60% of him water and needs water for many processes. Water contains no calories and does not provide energy. Many people recommend drinking 2 liters or 8 glasses of water a day, but you can also get it from food sources such as fruits and vegetables. If you drink enough fluids, your urine will turn pale yellow. Requirements also vary depending on a person’s height and age, environmental factors, activity level, health status, etc. The importance of water in the nutrition or diet is compulsory to get a fit and healthy body.



Micronutrients are essential in small amounts. They contain vitamins and minerals. Manufacturers sometimes add these to foods. Examples are fortified grains and rice.


The body needs carbon, hydrogen, oxygen and nitrogen. You also need minerals such as iron and potassium. In most cases, a varied and balanced diet will provide the minerals a person needs. If a deficiency occurs, your doctor may recommend supplements.


Potassium is an electrolyte. It keeps your kidneys, heart, muscles and nerves working properly. The 2015-2020 Dietary Guidelines for Americans recommend that adults consume 4,700 milligrams of potassium (mg) daily. Too little can lead to high blood pressure, stroke and kidney stones. Too much can be harmful for people with kidney disease. Avocados, coconut water, bananas, dried fruits, pumpkins, beans and lentils are goods sources of potassium. The importance of potassium in the balanced nutrition is that it help in the regulations of our nervous system and muscle contraction.


Sodium is an electrolyte that helps:

  • Maintaining nerve and muscle function
  • Regulates water balance in the body
  • Too little can cause hyponatremia.
  • Symptoms include lethargy, confusion, and fatigue.

The importance of sodium in the diet or nutrition food is compulsory because too much can lead to high blood pressure, which increases the risk of cardiovascular disease and stroke. Table salt, which consists of sodium and chloride, is a popular seasoning. However, most people consume too much sodium because sodium is already naturally present in most foods. Experts urge people to avoid adding table salt to their diet. Current guidelines recommend a daily sodium intake of no more than 2,300 mg, or about one teaspoon. This recommendation includes both naturally occurring sources and the salt people add to their diets. People with high blood pressure or kidney disease should eat less.


The body needs calcium to form bones and teeth. It also supports the nervous system, cardiovascular health, and other functions. Too little will weaken your bones and teeth. Symptoms of severe deficiency include tingling fingers and irregular heartbeats and can be life threatening. Too much can lead to constipation, kidney stones, and poor absorption of other minerals. Current guidelines for adults recommend an intake of 1,000 mg per day, and a woman over the age of 51 her 1,200 mg. Good sources include dairy products, tofu, legumes, and leafy greens.


Phosphorus is present in every cell of the body and contributes to bone and tooth health. Too little phosphorus can lead to bone disease and affect appetite, strength and coordination. It can also lead to anemia, an increased risk of infection, sore or burning skin, and confusion. Although there are toxicities from supplements, drugs, and problems with phosphorus metabolism, eating too much of it is unlikely to cause health problems. Adults should aim to consume about 700 mg of phosphorus daily. Good sources include dairy, salmon, lentils, and cashews.


Magnesium contributes to muscle and nerve function. It regulates blood pressure and blood sugar levels and enables the body to produce protein, bone and DNA. A lack of magnesium can eventually lead to weakness, nausea, fatigue, restless legs, trouble sleeping, and other symptoms. Too much can lead to digestive problems and ultimately heart problems. Nuts, spinach, and legumes are good sources of magnesium. An adult woman needs 320 mg of magnesium daily and an adult man she needs 420 mg.


Zinc plays a role in body cell health, the immune system, wound healing, and protein formation. Small amount can cause hair loss, skin irritation, taste and smell changes, and diarrhea, but this is rare. Too much can lead to digestive problems and headaches. Click here for more information. An adult woman she needs 8 mg of zinc per day and an adult man she needs 11 mg. Food sources include oysters, beef, fortified breakfast cereals, and baked beans. Click here for more information on dietary zinc sources.


Iron is essential for the formation of red blood cells, which carry oxygen to all parts of the body. It is also involved in the formation of connective tissue and the formation of hormones. Very little can lead to anemia, including digestive problems, weakness, and difficulty thinking. Read more about iron deficiency here. Too much can cause digestive problems, and very high levels can be fatal. Good sources include fortified cereals, beef liver, lentils, spinach, and tofu. Adults need 8 mg of iron per day, while women of reproductive age need 18 mg.


The body uses manganese for energy, plays a role in blood clotting, and supports the immune system. Too little can cause weak bones in children, skin rashes in men, and mood swings in women. Very much can cause tremors, muscle spasms, and other symptoms, but only in very high amounts. Mussels, hazelnuts, brown rice, chickpeas, and spinach provide manganese. Adult men need 2.3 mg and women 1.8 mg of manganese daily.


Copper helps the body gain energy and produce connective tissue and blood vessels. Very little amount of copper can lead to fatigue, pale skin, high cholesterol, and connective tissue disorders. Too much copper can cause liver damage, abdominal pain, nausea, and diarrhea. Too much copper also reduces zinc absorption. Good sources include beef liver, oysters, potatoes, mushrooms, sesame seeds, and sunflower seeds. Adults need 900 micrograms (mcg) of copper daily.


Selenium is made up of over 24 melanoproteins that play important roles in reproductive and thyroid health. As an antioxidant, it can also prevent cell damage. Too much selenium can cause symptoms such as garlic odor, diarrhea, irritability, skin rashes, and brittle hair and nails. Too little can lead to heart disease, male infertility, and arthritis. An adult he needs 55 mcg of selenium per day. Brazil nuts are an excellent source of selenium. Other plant-based sources include spinach, oatmeal, and baked beans. Tuna, ham, and fortified macaroni are excellent sources.


vitamin and mineral importance in body

Eating a variety of healthy foods can supply your body with different vitamins. Humans need small amounts of various vitamins. Some of these, like vitamin C, are also antioxidants. The importance of vitamin in the balanced nutrition means that they protect cells from damage by removing toxic molecules called free radicals from the body.

Vitamins are two types

Water soluble: 8 B vitamins and vitamin C

Fat soluble: Vitamins A, D, E, K

Water soluble vitamins

Humans need a regular intake of water-soluble vitamins. This is because the body breaks down water-soluble vitamins faster and simply cannot store them.

Fat-soluble vitamins

The body absorbs fat-soluble vitamins through the intestines with the help of fats (lipids). The body can store them and does not remove them quickly. People who follow a low-fat diet may not be able to absorb enough of these vitamins. If too many build up, problems can arise.

Some nutrients also act as antioxidants. These are vitamins, minerals, proteins, or other types of molecules. They help the body eliminate toxic substances known as free radicals or reactive oxygen species. Too much of these substances in the body can lead to cell damage and diseases.


Nutrition is the study of food and its effects on the body. People have to eat different diets to get different nutrients. Some people choose to follow a specific diet that focuses on certain foods and avoids others. Those who do this ensure that they get all the vitamins they need to stay healthy. You may need to plan carefully so that you can.

Diets high in plant foods and limiting animal fats, processed foods, added sugar and salt are most likely to benefit human health.
