Protein

One of the three nutrients used as energy sources (calories) by the body. Proteins are essential components of the muscle, skin, and bones. Proteins and carbohydrates each provide 4 calories of energy pergram, whereas fats provide 9 calories per gram.




carbohydrates






Mainly sugars and starches, together constituting one of the three principal types of nutrients used as energy sources (calories) by the body. Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen.

Fat



The body uses fat as a fuel source, and fat is the major storage form of energy in the body. Fat also has many other important functions in the body, and a moderate amount is needed in the diet for good health. Fats in food come in several forms, including saturated, monounsaturated, and polyunsaturated. Too much fat or too much of the wrong type of fat can be unhealthy.




Fibers



The parts of fruits and vegetables that cannot be digested. Fiber is of vital importance to digestion; it helps the body move food through the digestive tract, reduces serum cholesterol, and contributes to disease protection. Also known as bulk and roughage.

vitamins



Vitamins are organic components in food that are needed in very small amounts for growth and for maintaining good health. The vitaminsinclude vitamin D, vitamin E, vitamin A, and vitamin K, or the fat-soluble vitamins, and folate (folic acid), vitamin B12, biotin, vitamin B6,niacin, thiamin, riboflavin, pantothenic acid,and vitamin C (ascorbic acid), or the water soluble vitamins. Vitamins are required in the dietin only tiny amounts, in contrast to the energy components of the diet. The energy components of the diet are sugars, starches, fats, andoils, and these occur in relatively large amounts in the diet.

minerals



Minerals are inorganic elements that originate in the earth and cannot be made in the body. They play important roles in various bodily functions and are necessary to sustain life and maintain optimal health, and thus are essential nutrients. Most of the minerals in the human diet come directly from plants andwater, or indirectly from animal foods. However, the mineral content of water and plant foods varies geographically because of variations in the mineral content of soil from region to region.




water



A tasteless odorless colorless liquid with the chemical formula H2O. The liquid which forms rain, rivers, and the sea and makes up a large part of the bodies of most organisms, including humans.The amniotic fluid, as in the bag of waters.The cerebrospinal fluid, especially under increased pressure, as in water on the brain.
