Food is generally classified into six ( 6) groups and here they are:
Carbohydrates are important because the glucose derived from them are used as fuel by the cells of the body ( ATP).
Examples of Carbohydrates are: Bread, cereal, pasta, flour,ice cream, rice, nuts e.t.c
Proteins are building blocks of the body. They are structural materials. A good example is the keratin which is found in the skin. They can also serve as a source of fuel.
Sources of protein include fish, meat, eggs,milk, beans e.t.c
Lipids/Fats and oils:
Despite all you have heard, fats and oil actually have important roles to play in the body. For example, they serve as cushions for internal organs, they provide us with insulation and heat and can even be a source of fuel for the body.
Examples include cheese, egg yolk, olive oil, fish oil, nuts e.t.c
Vitamins are not needed in large quantities like the other group because they do not serve as fuels like the others. They help in the smooth functioning of the body’s processes. For example, we need vitamin D to be able to absorb calcium from the intestines. Vitamin B acts as a co-enzyme.
Examples include: Fruits like oranges, apples, strawberries. green leafy vegetables, nuts,legumes e.t.c
Like vitamins, minerals do not provide fuel for the body. They are inorganic compounds, and like nutrients, they help the body function smoothly. E.g, calcium is necessary for the bones and teeth, potassium in important for fluid and electrolyte balance. Minerals include calcium, phosphorus, magnesium, sulfur,potassium, e.t.c
Food sources of minerals include Dark green vegetables(calcium and potassium), milk and milk products(calcium), bananas( potassium), salt ( sodium), whole grains ( magnesium) e.t.c
Water is essential for survival. Approximately 60% of your body is made up of water and this is why water must be replaced frequently.
