CLASSIFICATION OF FOODS

• Classification by origin:• Foods of animal origin• Foods of vegetable origin

• Classification by chemical composition:• Proteins• Fats• Carbohydrates• Vitamins• Minerals

Proteins•Used for replacement and repair of body cells and

for growth•Made up of amino acids• Found in eggs, milk, cheese, and meat• Essential amino acids must be supplied by food.

Carbohydrates• The main source of energy for our body•Made up of carbon, hydrogen, and oxygen atoms;

energy holds these atoms together• Sugars are simple carbohydrates; starch and fiber are

complex carbohydrates.• Sugars are found in fruits, honey, and milk.• Starches are found in potatoes and pasta.• Fiber is found in whole-grain breads, beans, and peas.

Fats• Also called lipids•Classified as unsaturated or saturated based on their

chemical structure• Provide energy and help your body absorb vitamins•Because fat is a good storage unit for energy, any excess

energy is converted to fat.• Saturated fats are associated with high cholesterol.• Maintain healthy skin• Maintain body temperature• Promote healthy cell function

Vitamins• Needed for growth, regulating

body functions, and preventing disease.• A well-balanced diet usually

gives your body all the vitamins it needs.• Two groups: • Water-soluble -B-complex

and C• Fat-soluble-A, D, E, and K

Minerals• Are inorganic nutrients• Regulate many chemical reactions

in your body• Macro minerals are needed in

large amounts• Sodium, calcium, phosphorus,

magnesium, potassium, sulfur, chloride

• Trace minerals are needed in small amounts• Iron, zinc, manganese, copper, iodine• Excesses or deficiencies of trace

minerals can cause serious problems

Water• Required for survival.• Cells need water to carry out their work.• Most nutrients your body needs must be dissolved in water.• The human body is about 60 percent water.• You lose water each day when you perspire, exhale, and get

rid of wastes.

Rich in calcium Important for teeth and bones

Milk, yogurt, cheese High in Fat Good sources if vitamins A and

D

Primary source of protein in the diet

Protein provides body with dietary energy needed for growth and repair

FOOD PYRAMID

•“You are what you eat” that is what our elders would normally remind the young ones since

that is really true. It is more than a phrase but it is a reminder for us to eat right. It is

important for us to recognize the healthful properties of certain food. It is because eating

healthy food can help us prevent disease. Nutrients provide the body with everything it needs to grow and maintain healthy function.
