Whenever we take nutritious foods or liquids, our body digests and absorbs the simple but essential minerals, vitamins, fats, proteins, carbohydrates, fats and water from these nutritious foods or liquids and converts them into the bloodstream and energy that help our body. to grow and keep it healthy.
Nutritional value is most important to the health of any individual. Food or liquids whenever we ingest them affect both our body and our health. That is why it is very important that we are more aware of the food or liquids we eat in our daily lives. A large number of diseases occur only due to the wrong diet. A certain diet can by itself cause disease or alter the course of a disorder known as diabetes, heart or kidney disease.
Why is nutrition important to us?
As we know, food and water are necessary to strengthen our body and keep it healthy. Every good food and liquid contains important nutrition such as protein, carbohydrates, fat, some vitamins, minerals, and water. All of these play a different role in keeping our body healthy and building new cells in our body.
These are the important nutrients and their role in our body:
Protein:
Protein helps our body build muscle and strengthen the immune system. Proteins are basically made up of long chains of amino acids. There are 22 different types of amino acids, and our body needs all of these amino acids to function properly. Protein is a type of nutrient abundant in our body that builds new tissues and repairs all the damaged cells in our body. It also helps in the formation of hormones and enzymes that perform a variety of functions in our body, such as metabolism and sexual development. There are many types of proteins that perform different types of important functions in our body. For example, collagen is a protein and gives strength, elasticity and composition to our hair and skin. Some of the good sources of protein are lentils, low-fat dairy, tofu, walnuts, seeds, peas, and tempeh. Some common foods like whole wheat bread, potatoes, corn, and pasta also contain protein. Soy protein is the most essential and strongest protein and is equal to any protein of animal origin.
Carbohydrates:
Carbohydrates give us energy. This is an ideal source of energy for the body because carbohydrates are more easily converted to glucose. It helps our body to supply the energy necessary for the formation of the cellular component. Carbohydrates are made up of three compounds of carbon, hydrogen, and oxygen made by plants. There are four types of carbohydrates that are important: sugar, starches, fiber, and gums. If carbohydrates are taken regularly, they do not cause any weight gain, unless it is like another food group. There are two types of carbohydrates: complex and simple. The efficiency of carbohydrates can cause the body to produce ketones and can result in a condition known as ketosis. Good examples of carbohydrates are breads, potatoes, pasta, soda, potato chips, candy / sweets, cookies / biscuits, puddings, cakes, sugar, bananas, etc.
Fats:
Fat gives us extra energy. It is a nutrient and a certain amount of fat is necessary for our body. It doesn’t always make us fat. It plays a role in insulating our bodies by providing protection against sudden changes in temperature and also protects our vital organs. Fats are made up of a large group of compounds that are soluble in organic solvents and insoluble in water. Fat provides 9 calories per gram. When dietary fat is digested, fatty acids are produced. It is also important for healthy skin and the regulation of blood pressure.
There are two types of fat: saturated (solid at room temperature) and unsaturated (liquid at room temperature). To get an adequate amount of linoleic acid, one of the few fatty acids that the body cannot produce on its own. Any adult needs a tablespoon of unsaturated fat a day. Saturated fats are mainly found in dairy products like butter, cream, cheese, and some chocolates. The source of unsaturated fats are soybean, sunflower and corn oils.
Vitamins:
A vitamin is an organic compound, it regulates the processes of our body and plays an important role for our body to function properly. The term vitamin is derived from “vitamin”, a combined word for Vital and Amine. Today, a chemical compound is called a vitamin. Our body needs vitamins as substances to grow and develop normally. There are 13 vitamins necessary for our body. Some of them are A, B, C, D, E, K, vitamin B-6 and vitamin B-12. In our daily lives, we get most of all these vitamins from food, regardless of what we take. Our body can also produce vitamins D and K.
Each vitamin performs specific functions. Any low level of vitamins in particular causes deficiency disease. For example, if we don’t get enough vitamin D, it can cause rickets. Vitamin ‘A’ deficiency can cause night blindness.
If we eat a balanced diet, we automatically get enough essential vitamin from our food or daily liquid. We don’t even need to take any particular vitamin separately. Only in some cases do we need to take a daily multivitamin for optimal health.
Minerals:
Minerals regulate our body processes and also produce body tissues. Minerals make our body work properly like vitamins, but they do not prevent weight loss. Although we get it from our daily foods, we don’t need to take it separately. Minerals stimulate our immune system. Some important minerals are Chloride, Calcium, Copper, Chromium, Fluoride, Iron, and Iodine. These types of minerals can be found in our daily food or in liquid supplements such as salt, soy sauce, milk, vegetable oils, whole grains, cheese, nuts, etc.
Water shapes cells and acts as a medium where bodily processes can occur. It is the known but most important nutrient that our body needs. It is also the most abundant type of liquid found in our body, contributing 70% of our total mass. Helps dissolve and transport essential nutrients to all parts of the body. It is also necessary to help maintain body temperature and helps remove waste products from the body.
Water:
In the human body there is 70% of the total mass that is covered by water. Water shapes cells and acts as a medium where bodily processes can occur. It is a very necessary nutrient for all available nutrients. It is also the most abundant type of fluid found in the human body. Water helps maintain body temperature and helps remove waste products from the body.
We see that nutrition plays a very important role in our lives, each food and liquid contains its own nutritional value which is very necessary in our life. It could help to extend or decrease our life expectancy, as well as to define our degree or means of life. It also helps in our mental and physical development. We must be aware of the foods and liquids that we usually drink. Popper food in our daily life leads to a lifelong habit towards a long healthy life.
