Nutrition

Nutrition (also called nourishment or aliment) is the provision, to cells and organisms, of the materials necessary (in the form of food) to support life. Many common health problems can be prevented or alleviated with a healthy and nutritious diet.

There are six major classes of nutrients: carbohydrates, dietary fiber, fats, minerals, protein, vitamins, and water

Carbohydrates include sugars, starches and fiber. They constitute a large part of foods such as rice, noodles, bread, and other grain-based products.

Dietary fibre, whole grains, fruits (especially plums, prunes, and figs), and vegetables are good sources of dietary fibre.

Fat, Saturated fats basically comes from animal sources. Unsaturated fats (e.g., vegetable oil) are considered healthier. While trans fats are to be avoided. Saturated and some trans fats are typically solid at room temperature (such as butter or lard), while unsaturated fats are typically liquids (such as olive oil or flaxseed oil).

Proteins are the basis of many animal body structures e.g. muscles, skin, and hair. Sources of protein include meats, tofu and other soy-products, eggs, legumes, and dairy products such as milk and cheese.

Vitamins are recognized as essential nutrients, necessary in the diet for good health. Vitamin deficiencies may result in disease conditions, including goitre, scurvy, osteoporosis, impaired immune system, disorders of cell metabolism, certain forms of cancer, symptoms of premature aging, and poor psychological health.

Water about 20 percent of water intake comes in food, while the rest comes from drinking water and assorted beverages (caffeinated included) Water is excreted from the body in multiple forms; including urine and feces, sweating, and by water vapor in the exhaled breath.

As Pakistan is an agricultural country, therefore the growth of fresh fruits and vegetables are enormous in number. Similarly Pakistan is rich in minerals and vitamins and has the favorable weather conditions. In short Pakistan is naturally rich country as far as natural resources are concerned.

Though we can easily benefit from our country's natural resources but due to lack of education required for the utilization of these resources keep us deprived of its advantages.
