- Biology: Diet and Exercise
- Nutrients
- Three main food groups are: Carbohydrates, proteins and fats
- Carbohydrates
- e.g. bread, pasta and rice
- A source of energy for life processes
- Proteins
- e.g. meat, fish and eggs
- For growth, repair and building cells
- Fats
- e.g. cheese, butter and oils
- A source of energy for life processes and to make cell membranes and insulation
- Carbohydrates
- The seven nutrients a human needs are: protein, fibre, water, carbohydrates, minerals, vitamins and fats
- Three main food groups are: Carbohydrates, proteins and fats
- Imbalanced diets
- Too little food cuases a person to be underweight. Too much food causes a person to be overweight
- Malnourished is not having the right amount of nutrients in a diet
- A poor diet
- Overweight, obesity, deficiency diseases
- E.g. scurvy, rickets and night blindness
- Overweight, obesity, deficiency diseases
- Metabolic rate
- The rate of chemical reaction in your cells.
- Varies due to genetic traits, proportion of muscle to fat, gender and the amount of exercise
- Exercise
- Increases good cholesterol
- Builds muscle tissue, increasing metabolic rate
- Reduces risk of: arthritis, type 2 diabetes, high blood pressure and heart disease
- Less likely to be overweight
- Cholesterol
- Good cholesterol
- needed for hormones and cell membranes
- High-density liproprotein
- Bad cholesterol
- Heart disease
- Low-density lipoprotein
- Good cholesterol
- Nutrients
