- DIET + FOOD PRODUCTION
- Balanced Diet
- provides all the essential nutrients in the correct proportions
- CARBOHYDRATES
- main energy source
- PROTEINS
- growth+repair of tissues
- FATS
- energy, cell membranes, waterproofing
- VITAMINS
- chemical processes e.g. blood clotting
- water soluble or fat soluble
- chemical processes e.g. blood clotting
- MINERALS
- inorganic elements essential for normal function
- WATER
- transport + main component of body (60%)
- used up in breathing/ urinating/ sweating
- transport + main component of body (60%)
- FIBRE
- movement of food through gut
- undigestible
- movement of food through gut
- CARBOHYDRATES
- provides better health, immune system, stronger, less ill
- an unbalanced diet leads to MALNUTRITION
- ENERGY IN = ENERGY OUT
- otherwise this can lead to OBESITY >20% heavier than recommended weight for their height
- provides all the essential nutrients in the correct proportions
- Obesity
- otherwise this can lead to OBESITY >20% heavier than recommended weight for their height
- caused by:
- underactive thyroid gland
- combination of too much fatty/sugary food+little exercise
- increases risk of diabetes(2), heart disease, arthritis, cancer, hbp, CHD and cancer
- CHD
- extra energy is stored as fat building up as adipose tissue
- this causes build up of atherosclerosis deposit on the coronary artery walls
- this causes a narrowing of the artery lumen restricting blood flow to hear muscle
- leads to O2 starvation
- causes angina during exercise
- leads to O2 starvation
- happens naturally as=body's response to ruptures-its a damage and repair system
- can be sped up by hbp, tobacco smoke +other toxic chems
- this causes a narrowing of the artery lumen restricting blood flow to hear muscle
- this causes build up of atherosclerosis deposit on the coronary artery walls
- RISK INCREASED:
- Salt
- increases water potential in blood so more water is held in blood increasing bp causing hypertension+ damages inner lining of arteries during diastole leading to ather.
- Fats
- saturated (animal) raise blood cholesterol leading to build up of fatty deposits
- Cholesterol
- Untitled
- Salt
- extra energy is stored as fat building up as adipose tissue
- CHD
- growing issue over last 20yrs
- Balanced Diet
