Food and Energy Notes• Food: provides the materials for energy, growth

and repair of tissues.• Calorie: amount of energy needed to raise the

temperature of one gram of water by one degree Celsius.

• Metabolism: represents the sum of all chemical reactions that takes place within an organism.

• Nutrients: substances in food that provide the raw materials and energy the body needs to carry out all vital processes. There are six (6) nutrients: carbohydrates, fats, proteins, vitamins, minerals and water.

• Human Body: ~ 60-70% water

Food and Energy Notes• Carbohydrates: major source of quick

energy; provides the raw materials to make parts of cells

• Fats: stored energy. Fats form part of the cell membrane and fatty tissue protects and supports your internal organs and insulates your body. Brain Development

• Protein: needed for tissue growth and repair/maintenance (ex: muscle). Proteins play a role in chemical reactions within the cell (= enzymes).

Food and Energy Notes• Vitamins and Minerals are needed in

small amounts to carry out chemical reactions.

• Water is important because the chemical reactions take place in water; blood flows due to water; joints lubricated by water; body temperature is regulated by water (perspiration/sweat).

CarbohydratesSimple: candy, fruits, milk

Complex: Breads, Rice, Pasta, Crackers
