|Nutritional Elements Of Food
| Nutrition is the supply of materials that are necessary to support life. Nutrition is given in the form of food and many common health problems can be prevented if we have good nutrition.
However, there are important nutritional elements of food that you should take regularly. These are carbohydrates, fats, fiber, mineral, proteins, vitamins and water.
Carbohydrates are classified as monosaccharides, disaccharides and polysaccharides depending on the number of sugar units they contain. Polysaccharides are also referred to as complex carbohydrates because they have long chains of sugar units. Monosaccharides and disaccharides are simple carbohydrates unlike polysaccharides which are complex carbohydrates. Complex carbohydrates take longer to metabolize while simple carbohydrates metabolize rapidly and can raise the blood sugar levels very quickly.
Fats are made up of fatty acids which are bonded to glycerol. Fats are classified as saturated and unsaturated. In saturated fats, the carbon atoms are connected to hydrogen atoms, whereas in unsaturated fats, the carbon atoms are double-bonded in place of a hydrogen atom.
Fiber mainly consists of cellulose that is indigestible as we do not have the required enzymes to break it down. Fiber provides bulk to the intestinal contents and stimulates rhythmic muscular contractions in the digestive tract. We primarily get out fiber content from fruits and vegetables.
Protein is one of the most important nutritional elements of food and is composed of amino acids that are the building blocks of muscles, skin, hair and other body structural materials. Our body constantly requires amino acids to produce new proteins and to replace damaged one that are lost in the urine. You can get proteins through meat, eggs, grains, legumes and diary products.
Having a deficiency or excess of vitamins is harmful for the body and a person can suffer from health conditions like goiter, scurvy, osteoporosis, weak immune system, certain forms of cancer, premature aging, and poor psychological health.
Our body is composed of 70 percent water and in order to function properly, it requires anywhere between one and seven liters of water each day.
