The Nutrient Content of Food

The human body requires food to survive. Food is any material taken from the living planet to provide nutrition to an organisms for its complete growth. Food is generally of vegetable, animal or fungus origin, and comprises all necessary nutrients, including proteins, vitamins, carbohydrates, or minerals, in a particular quantity at a specific time. This food is known as dietary food and is taken to meet nutritional requirements for daily life.


The most important food components are carbohydrates, which are found in various forms such as glucose, glycogen, or simple sugars. Complex carbohydrates are made from starches and can be found in fruit, vegetables, legumes, bread, pasta, rice and other grains. Fruits and vegetables are rich in vitamin and mineral substances, especially carbohydrates. Animal products, like meat, dairy products, eggs, milk, poultry, fish and other seafood also contain fat and protein. Animal fat provides an important source of energy.

The fat that is obtained from some animal sources, particularly beef, pork, butter, cheese, ice cream and others, and is known as palmitic acid, is highly soluble in water and excreted as a liquid. This type of fat is particularly beneficial for maintaining a stable blood sugar level and it has been found to be useful for lowering cholesterol levels as well. However, the benefits of this fat are more beneficial when it is unsaturated fatty acid rather than monounsaturated fatty acids, which have a much greater ability to raise the level of blood cholesterol.
