Essential Nutrients That Supply Energy Essential Nutrients That Supply Energy Photo Credit: Yulia_Davidovich/iStock/Getty Images The body requires energy to sustain itself and perform all the functions of daily life. The process of converting nutrients from food into energy is called cellular respiration. The energy from this biochemical process is captured in a chemical called adenosine triphosphate (ATP). Subsequent breakdown of ATP releases the energy needed to drive cellular functions. Carbohydrate, fat and protein provide the fuel needed for energy production from food. Additionally, thiamin, niacin, riboflavin and other B vitamins help with the conversion of nutrients into energy. Video of the Day

Six Basic Nutrients Required for Sustaining a Healthy Body Protein is essential as part of the Six basic Nutrients because the body is made of proteins. Proteins consist of amino acids. The body needs about 22 amino acids to make all its proteins, but can only manufacture 14 of these in its cells. The rest of the amino acids are derived from food intake.

- 608 Unit 5: Human Biology Protein is another essential nutrient; it is the material that the bodyuses for growth and repair. Cells in your body—such as those com-posing muscles, bones, and skin—are built of proteins. Carbohydratesare nutrients that provide cells with energy.

- There are, however, some 45 or so nutrients that the human body is incapable of manufacturing. These nutritional elements are called essential because it is essential for humans to incorporate them into their diets. The essential nutrients can be divided into six general categories: water, proteins, carbohydrates, fats, vitamins, and minerals. Strictly speaking, fiber is not an essential nutrient, but it is also extremely important in prevention of certain diseases.

6 Essential Nutrients and Why Your Body Needs Them 6 Essential Nutrients and Why Your Body Needs Them. Essential nutrients. Essential nutrients are compounds that the body can’t make or can’t make in sufficient quantity. According to the World Health Organization, these nutrients must come from food, and they are vital for disease prevention, growth, and good health. While there are many essential nutrients, they can be broken up into two categories: macronutrients and micronutrients. Macronutrients are eaten in large amounts and include the building blocks of your diet by providing the body with energy: protein, carbohydrates, and fat.

- Food has six types of nutrients-carbohydrates, proteins, fats, vitamins, minerals and water. These are essential to perform all daily and metabolic activities. Carbohydrates are compounds of carbon, hydrogen and oxygen, always in the ratio of 2:1:1.

- Stockbyte/Stockbyte/Getty Images. Proteins. Protein is the third primary source of energy that our bodies need. Protein is extremely important to the growth of our cells and all of the metabolic and biological processes that go on inside our bodies.ave. Our bodies are finely tuned machines and like most machines our bodies need fuel. All the energy that our bodies need comes from the foods that we eat. So, if you deprive your body of any of the three sources of energy (proteins, fats and carbohydrates), it won't run efficiently.

- Your body gets energy, which is measured in calories, from the foods you eat. The nutrients that provide calories and yield food energy are carbohydrates, fats and proteins. These nutrients are called macronutrients.

Health & Nutrition - BIO 103 Chapter 1 - 6 Classes of Nutrients The body can synthesize (make) many nutrients, such as the lipids cholesterol and fat, but about 50 nutrients are dietary essentials. An essential nutrient must be supplied by food, because the body does not synthesize the nutrient or make enough to meet its needs. Water is the most essential nutrient.

The Bodyâs Fuel Sources The Body’s Fuel Sources Our ability to run, bicycle, ski, swim, and row hinges on the capacity of the body to extract energy from ingested food. As potential fuel sources, the carbohydrate, fat, and protein in the foods that you eat follow different metabolic paths in the body, but they all ultimately yield water, carbon dioxide, and a chemical energy called adenosine triphosphate (ATP).

- Nutrients are drawn from a wide variety of foods and the more varied your diet, the more likely you are to obtain all the nutrients you need. Energy is not a nutrient but, kilojoules (food energy) are important for providing energy for your daily activities. Protein, fats and carbohydrates are converted into energy in different quantities. Vitamins and minerals are also essential nutrients for the body, but they are not converted into energy.

THE DEFINITION OF NUTRIENTS Nuts and seeds are also a great source of protein. 3. FAT - Fats are essential for fuel and storing energy so they are an important part of the definition of nutrients. Yet be aware that there are good fats and bad fats. Here's a break down of the different types of fats.

- Glucose is the primary energy source for the body's cells and the only energy source for the brain and nervous system. A steady supply must be available for use, and a relatively constant level of glucose must be maintained in the blood. A few different protocols may be used to evaluate the glucose level in the blood.

Why Nutrition is Important and Basic Rules Everyone should Follow Breakdown of Foods. The nutrients derived from foods can be broken down into three main categories: 1. Carbohydrates 2. Lipids (fats) 3. P roteins. These, along with vitamins, minerals and water are metabolized (broken down) by the body in order to satisfy all of its energy needs.

Five Main Nutrients the Body Needs Water-soluble vitamins, which include the B-complex vitamins and vitamin C, are not stored by your body and must be supplied daily. Vitamin A, for example, is essential for proper vision; B vitamins help convert food to into energy; and vitamin D aids calcium and phosphorus in strengthening bones and teeth.

Nutrients 101: Essential and Non-Essential Nutrients Explained Some non-essential nutrients are also found in the diet, although many are also made by the body. You need a variety of proteins, fats and carbohydrates every day because these are the precursors of energy, amino acids and essential fatty acids, as well as containers of essential vitamins, minerals, and phytonutrients.

- Energy is not a nutrient but, kilojoules (food energy) are important for providing energy for your daily activities. Protein, fats and carbohydrates are converted into energy in different quantities. Vitamins and minerals are also essential nutrients for the body, but they are not converted into energy. Energy is required to fuel body processes (metabolism) and physical activity. If we consume more energy than we use for metabolism and physical activity, the excess is stored as body fat. You need to be sure to balance the energy you consume through foods with the energy you expend during the day.
