Food is not a source of nutrients in its original form and is not absorbed into the cells and blood unless first broken down into small blocks. This process-digestion-takes place in the digestive tract, where it is then absorbed by the intestines, transported in the blood stream to each organ, and then taken up into cells.

Nutrition Module: 2. Nutrients and their Sources

In the previous session you learned about nutrition, nutrients, food and food choices. In this session, you will learn about each nutrient in more detail. You will learn about the major categories of nutrients, the main sources of these, their function, and how our body uses each of these nutrients for healthy growth and development. There are seven main classes of nutrients that the body needs. These are carbohydrates, proteins, fats, vitamins, minerals, fibre and water. It is important that everyone consumes these seven nutrients on a daily basis to help them build their bodies and maintain their health. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases.

Nutrient Classifications

There are six essential nutrients that people need to consume through dietary sources to maintain optimal health. The WHO divide these essential nutrients into two categories: micronutrients and macronutrients. Micronutrients are nutrients that a person needs in small doses. Micronutrients consist of vitamins and minerals. Although the body only needs small amounts of them, a deficiency can cause ill health. Macronutrients are nutrients that a person needs in larger amounts.

6 Essential Nutrients and Why Your Body Needs Them

There are 6 essential nutrients that the body needs to function properly. Nutrients are compounds in foods essential to life and health, providing us with energy, the building blocks for repair and growth and substances necessary to regulate chemical processes. Looking at the AGHE, what food groups are the primary sources of each of the following? Proteins: meat, dairy, legumes, nuts, seafood and eggs Carbohydrates: pasta, rice, cereals, breads, potatoes, milk, fruit, sugar Lipids most commonly called fats : oils, butter, margarine, nuts, seeds, avocados and olives, meat and seafood Vitamins: common vitamins include the water soluble B group vitamins and vitamin C and the fat soluble vitamins A, D, E and K Fruits and vegetables are generally good sources of Vitamin C and A and folic acid a B group vitamin Grains and cereals are generally good sources of the B group vitamins and fibre Full-fat dairy and egg yolks are generally sources of the fat soluble vitamins A, D and E Milk and vegetable or soya bean oil are generally good sources of vitamin K, which can also be synthesised by gut bacteria Minerals: sodium, calcium, iron, iodine, magnesium, etc.

While there are many essential nutrients, they can be broken into two categories: macronutrients and micronutrients. Macronutrients are eaten in large amounts and include the primary building blocks of your diet — protein, carbohydrates, and fat — which provide your body with energy. Vitamins and minerals are micronutrients, and small doses go a long way. There are six main groups of essential micronutrients and macronutrients. Protein is having its moment, and not just in the workout community.

What are the 6 essential nutrients?

A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals , plants , fungi , and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair , scales , feathers , or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates , lipids , proteins , and fermentation products ethanol or vinegar , leading to end-products of water and carbon dioxide. All organisms require water.

A classify nutrients, their functions, and food sources and compare the nutritive value of various foods; B assess the effects of nutritional intake on health, appearance, effective job performance, and personal life; C analyze and apply various dietary guidelines throughout the life cycle, including pregnancy, infancy, childhood, and late adulthood; and D compare personal food intake to recommended dietary guidelines. Nutrients are the chemical substances in the foods we eat. Our bodies use these nutrients for energy and to support growth, maintenance, and repair of tissues.

Это аварийное электропитание в шифровалке было устроено таким образом, чтобы системы охлаждения ТРАНСТЕКСТА имели приоритет перед всеми другими системами, в том числе освещением и электронными дверными замками. При этом внезапное отключение электроснабжения не прерывало работу ТРАНСТЕКСТА и его фреоновой системы охлаждения.
