- B1: Diet and Exercise
- Blood pressure
- Systolic - maximum pressure the heart produces
- measured in mmHg
- Diastolic - pressure between the heart beats
- measured in mmHg
- high pressure
- can cause a stroke, and damage to kidneys
- stressful lifestyle
- increase of heart disese
- smoking
- high pressure
- can cause a stroke, and damage to kidneys
- stressful lifestyle
- increase of heart disese
- smoking
- Carbon monoxide decrease haemoglobin ability to carry oxygen
- saturated fat
- build up of cholesterol in arteries (plaque)
- the narrowing of arteries is caused by the plaque in the coronary arteries.
- blood clots or thrombosis more likely to occur
- the narrowing of arteries is caused by the plaque in the coronary arteries.
- build up of cholesterol in arteries (plaque)
- salt

- salt
- smoking
- increase of heart disese
- low pressure
- can cause dizziness, fainting and poor circulation
- serious medical illness
- everyday factors - eaten recently, time of day etc..
- injury
- genetics
- Systolic - maximum pressure the heart produces
- Health
- being free from disease
- Fitness
- the ability to do exercise
- cardio
- strength
- flexibility
- stamina
- agility
- speed

- flexibility
- strength
- Body mass index
- Used to indicate if you're over or underweight.
- 30 + obese
- 20 - 25 normal
- >20 underweight
- BMI = mass(kg) / (height (M) ) squared
- Used to indicate if you're over or underweight.
- EAR
- depends on age, pregnancy, lactation
- Daily requirement of protein
- EAR = 0.6 X body mass(kg)
- lack of protein can lead to defiency called KWASHIORKOR
- Daily requirement of protein
- depends on age, pregnancy, lactation
- Diet
- Main componats of healthy diet
- carbohydrate
- made up of simple sugars such as glucose
- stored in the liver as glycogen or converted into fats
- starch is complex carbohydrate
- made up of simple sugars such as glucose
- protein
- made up of Amino Acids
- cannot be stored in the body
- FIRST CLASS
- sourced from animals - meat and fish
- contain all essential amino acids that cannot be made by human body
- sourced from animals - meat and fish
- SECOND CLASS
- made by plants - pulses and lentils
- do not contain essential amino acids
- made by plants - pulses and lentils
- however body can convert between amino acids
- FIRST CLASS
- cannot be stored in the body
- EAR
- depends on age, pregnancy, lactation
- Daily requirement of protein
- EAR = 0.6 X body mass(kg)
- lack of protein can lead to defiency called KWASHIORKOR
- Daily requirement of protein
- depends on age, pregnancy, lactation
- made up of Amino Acids
- fat
- made up of fatty acid and glycerol
- stored under skin and around organs
- stored as ADIPOSE TISSUE
- stored under skin and around organs
- made up of fatty acid and glycerol
- carbohydrate
- Main componats of healthy diet
- Blood pressure
