Whenever we take any food or nourishing liquids, our body digests and absorbs the simple but essential minerals, vitamins, fats, proteins, carbohydrates, fats and water from these food or nourishing liquids and converts it into the bloodstream and energy that help our body to grow and keep it healthy.
The nutrition value is more important for any individual's health. The food or liquids whenever we take it affect our body and health as well both. So it is very important that we should be more aware of the foods or liquids whatever we take in our daily life. A large number of diseases occur only due to wrong diet. Some certain diet may itself cause some disease or alter the course of a known disorder such as diabetes, heart or kidney disease.
Why Nutrition is important for us?
As we know that food and water is necessary to build up our body and keep it healthy. Every good food and liquid contains some important nutrition like proteins, carbohydrate, fats, some vitamins, minerals and water. These all play different role to keep our body healthy and build new cells in our body.
These are the important nutrition and their role in our body:
Protein helps our body to build muscles and strong immune system. Basically proteins are made up of long chains of amino acids. There are 22 different types of amino acid and our body needs all these amino acid to function properly. Protein is abundant type of nutrient in our body that builds new tissues and repairs all damaged cells in our body. It also helps in formation of hormones and enzymes which play variety of roles in our body such as metabolism and sexual development. There are many types of protein that play different types of important role in our body. For example collagen is a protein and it gives the strength, elasticity and composition of our hair and skin. Some of the good protein sources are lentils, low-fat dairy products, tofu, nuts, seeds, peas, tempeh. Some common foods such as whole grain bread, potatoes, corn and pasta also have protein. Soya protein is the most essential and strong protein and it is equal to any animal origin protein.
Carbohydrates give us energy. This is an ideal source of energy for the body because carbohydrates converted more readily into glucose. It helps our body to supply the energy for the formation of cellular constituent. Carbohydrates are made up of three compounds Carbon, Hydrogen and Oxygen formed by plants. There are four types of carbohydrates are important - Sugar, Starches, Fiber and Gums. If carbohydrates taken regularly it doesn't cause any weight gain, unless like other food group. There are two types of carbohydrates - Complex and Simple. Efficiency of carbohydrates can cause the production of ketones in the body, it can results into a condition known as ketosis. The good examples of carbohydrates are breads, potatoes, pasta, soda, chips, candies/sweets, cookies/biscuits, puddings, cakes, sugar, bananas etc.
Fat provides us extra energy. It is a nutrient and a particular amount of fat is necessary for our body. It doesn't always make us fat. It play role to insulate our bodies by giving us protection from sudden changes in temperature and also protects our vital organs. Fats consists of a wide group of compounds are soluble in organic solvents and insoluble in water. Fats provide 9 calories per gram. When dietary fat is digested, fatty acids are produced. It is also important for healthy skin and blood pressure regulation.
There are two types of fats Saturated (solid at room temperature) and Unsaturated (liquid at room temperature). To obtain an adequate amount of linoleic acid, one of the few fatty acids the body cannot produce on itself. Any adult needs one tablespoon of unsaturated fat daily. Saturated fats mainly occur in dairy products like butter, cream, cheese and some chocolates. The source of unsaturated fats are soybean, sunflower and corn oils.
A vitamin is an organic compound, it regulate our body processes and plays an important role to make our body function properly. The term vitamin was derived from 'vitamine', a combination word from 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 life we get all most all these vitamins form foods whatever we take. Our body can also produce vitamins D and K.
Each vitamin plays specific jobs. Any particular low levels of vitamins cause deficiency disease. For example, if we don't get enough vitamin D it can cause rickets. Deficiency of vitamin 'A' can cause Night Blindness.
If we eat a balanced diet we get enough essential vitamin automatically form our daily food or liquid. We don't even need to take any particular vitamin separately. Only in some cases we need to take a daily multivitamin for optimal health.
Minerals regulate our body processes and also make body tissues. Minerals make our body work properly same as vitamin play the role but it doesn't prevent weight loss. Although we get it form our daily foods, so we don't need to take it separately. Minerals boost our immune system. Some important minerals are Chloride, Calcium, Copper, Chromium, Fluoride, Iron and Iodine. These types of minerals can be found from our daily food or liquid supplement like salt, soy sauce, milk, vegetable oils, whole grains, cheese, nuts etc
Water gives cells shape and acts as a medium where body processes can occur. It is the well known yet most important nutrient our body needs. It is also the most abundant type of liquid found in our body contributing 70% of our total mass. It helps to dissolve and carry the essential nutrients to all parts of the body. It is also needed to help maintain the body temperature and aids to carry away the body's waste products.
