Question

Explain the two Classes of Nutrients and their examples ?

Answer 1

Nutrients are grouped in to macronutrients & micronutrients.Carbohydrates,proteins,fats and water are macronutrients and vitamins & minerals are micronutrients.Although most of the foods are mixtures of nutrients.Many of them contain alot of one nutrient and a little of the other nutrients.

MACRONUTRIENTS;

Carbohydrates ;- are a type of macronutrient used for quick energy in cells.The basic unit of carbohydratesis a monosaccharide.An example of monosaccharide is glucose or sugar.Glucose can be by itself,or assembled in to long chains to make things like starch,which can be found in potatoes.Foods that contain carbohydrates include grains,cereal,bread,pasta,potatoes,fruits & sweets such as soda & candy.

Proteins ;- are a macronutrient that the cells in your body use for structure.Protein is very important for building tissues such as muscles.Muscle is mainly made up of proteins.

Fats ;- are called lipids & are a macronutrient in your body that stores energy.Fats have long chains of carbon & hydrogen,which store lots of energy in the chemical bonds.Fats are important in our body to cushion organs,protect our cells and send signals in the form of hormones around our body.Foods that are rich in fats are butter & oil.

MICRONUTRIENTS;

They are also called trace elements & are present in plant bodies in very small amounts.Examples include cobalt,manganese,zinc etc.

Beneficial nutrients ; They are plant nutrients that may not be essential,but are beneficial to plants.
