Study Notes
Calories
- Calories are necessary for survival, enabling breathing, movement, and blood pumping
- Calories come from food consumed each day
- The amount of calories in food is measured by its potential energy
- A calorie is a unit of energy
- A calorie raises the temperature of 1 gram of water by 1.8 degrees Fahrenheit
- One calorie equals 4.184 joules
- Calories are commonly listed per serving
- Calories are associated with food and other substances like gasoline
- A gallon of gasoline contains approximately 31,000,000 calories
- Food labels list calories as kilocalories (kcal)
- 1 kilocalorie = 1,000 calories
- A can of soda with 200 food calories actually contains 200,000 calories.
- The number of calories needed by an individual varies based on factors like activity level, age, gender, and weight
- Most people need about 2,000 calories per day (based on a 2,000 calorie per day diet)
- A person taking in more calories than needed will gain weight
- A person taking in fewer calories than needed will lose weight
- Exercise increases metabolism, burning calories faster
- Some people have higher metabolisms than others
Types of Nutrients in Food and Calories
- Carbohydrates, proteins, and fats are nutrients found in food
- 1 gram of carbohydrates has 4 calories
- 1 gram of protein has 4 calories
- 1 gram of fat has 9 calories
- Nutritional labels list calories from different nutrients.
Metabolic Processes and Calories
- The body breaks down carbohydrates, fats, and proteins to use as energy
- Carbohydrates break down into glucose
- Fats break down into glycerol and fatty acids
- Proteins are broken down into amino acids
- These molecules are transported by bloodstream to body cells
- The cells use these molecules as energy or store them.
