Why do you need Nutrients?

The human body requires nutrients in order to function well. If you aren’t getting the nutrients your body needs, you can easily slip into depression. The nutrients known to be essential for human beings are proteins, carbohydrates, fats and oils, minerals, vitamins, and water.

Proteins are made of amino acids which are necessary for growth and tissue repair.. Animal foods such as meat, fish, poultry, milk, and eggs are rich in protein. Good plant sources of protein are beans, peas, nuts, bread, and cereals.

Starches and sugars are carbohydrates, the main source of the body’s energy. Carbohydrates account for about half of the calorie intake Carbohydrate-rich foods are also the main sources of protein for most of the world. Rice, wheat, corn, and potatoes are common rich sources of carbohydrates.Sugars are not essential foods. It is an empty calorie food.

Fats and oils are a source of energy. Fats in the diet are necessary for good health. They make certain vitamins available for use in the body, they cushion vital organs, they make up part of all body cells, and they help to maintain body temperature.

Minerals are equally important. Almost all foods consist of some essential minerals. Most minerals are easy to obtain in quantities required by the body. A major exception is iron for children under age 4 and adolescent girls and women in the childbearing years. These groups need more iron than a normal diet may provide. Iron helps to build red blood cells. It also helps the blood carry oxygen from the lungs to each body cell. Rich sources of iron are meat, especially liver; egg yolks; and dark green vegetables. Calcium builds bones and teeth, and it is necessary for blood clotting. The best sources are milk and hard cheese, leafy greens, nuts, and small fishes.  Phosphorus works with calcium to make strong bones and teeth.  Other important minerals are sodium, potassium, iodine, magnesium, zinc, and copper.

Eating a wide variety of foods ensures getting enough vitamins whether or not they are identified. All living things need vitamins for growth and health. The body either cannot manufacture them at all or cannot normally manufacture them in sufficient amounts, and so must absorb them from food. Each vitamin has specific roles to play. Almost all foods contribute to a varied intake of essential minerals.
Fat-soluble vitamins. Four vitamins–A, D, E, and K–are known as the fat-soluble vitamins. They are digested and absorbed with the help of fats that are in the diet.
Vitamin A which is needed for strong bones, good vision, and healthy skin. They are found dark green and yellow fruits and vegetables.
Vitamin D is essential for children because it helps calcium and phosphorus to form straight, strong bones and teeth. The body can manufacture its own vitamin D in the presence of sunlight
Vitamin E helps to protect vitamin A and red blood cells. It is found in a wide variety of foods
Vitamin K is one vitamin that is made within the human body–by bacteria that live in the intestinal tract.  Green leaves of spinach, kale, cabbage, and cauliflower and also in pork liver have small amounts of it.
Fat-soluble vitamins can be stored in the body for long periods. They are stored mostly in the fatty tissue and in the liver.
Water-soluble vitamins. The vitamin B group of several vitamins helps to maintain healthy skin and a well-functioning nervous system. B vitamins also help to convert carbohydrates into energy. Vitamin C is needed for building the connective tissue that holds body cells together, healthy teeth, gums, and blood vessels, it helps the body to absorb iron. As they are not stored in the body it is essential to consume food containing the same.

Water makes up about 60 percent of an adult’s body weight. Most fruits and vegetables  contain more than 90 percent water. It is essential to drink water (8 to 10 glasses but it can increase based on your activity and body weight).Water rids your body of toxins; provides the conduit through which nutrients are carried to your cells; and gives moisture to your ears, nose and throat. Water also prevents dehydration, which can make your organs malfunction and can be deadly. Some of the symptoms of nutrition deficiency  are, bleeding gums, slow wound healing, loss of sense of taste, muscle cramps, burning sensation on feet, anaemic, brittle bones, leg cramps, gum disease, dry skin to name a few. Medication is also known to cause nutrient  depletion, they might be stealing nutrients from your system or preventing their absorption’. As a result, you could end up feeling worse. Vitamins, minerals, and other nutrients can give your skin the youthful glow of good health.
