Q

how can you make up not eating enough HBV PROTIENS

A

By eating two LBV proteins in the same meal, you can make up for the lacking amino acids in each, therefore giving yourself a meal with a high biological value (HBV).

17
Q

what are the 2 types of carbohydrates

A

simple and complex carbohydrates

18
Q

what is another way of saying simple and complex carboyhrates

A

sugars and starches

19
Q

what effect does sugars have on your body

A

Sugars (simple) – these raise the body’s blood sugar level very quickly, as they enter the blood stream rapidly after they are eaten.

20
Q

what effect does starches have on your body

A

Starches (complex) – these keep blood sugar levels constant, because they enter the blood stream very slowly.

21
Q

what are sources of carbohydrates (complex)

A

bread – including bagels and wraps
rice
pasta
cereal
potatoes

22
Q

what are functions of carboydrates

A

for energy
fibre
growth and repair

23
Q

what are sources of carbohydrates (simple)

A

sweets
biscuits
shakes
honey
table sugar

24
Q

what are the 2 types of fats

A

There are two types of fat – saturated fat and unsaturated fat.

25
Q

unsaturated fats can be either _______________ or _____________

A

monounsaturated fat or polyunsaturated fat.

26
Q

what is an unsatured fat

A

Unsaturated fat is liquid at room temperature, for example rape seed oil or olive oil.

Unsaturated fats come from plant sources and therefore are better for us than saturated fats.

27
Q

what is a saturated fat

A

Saturated fat is usually solid at room temperature, for example butter.

Saturated fats come from animal sources and therefore tend to be very unhealthy.

28
Q

what is a monosaturated fat

A

Monounsaturated fats have one double bond (‘mono’ meaning one

29
Q

what is a polysaturated fat

A

Polyunsaturated fats have more than one double bond (‘poly’ meaning many)

30
Q

where can we get saturated fats from

A

red meat
dairy products

31
Q

where can we get unsaturated fats from

A

polyunsaturated fat is in margarine, vegetable oil and oily fish (e.g., mackerel)

monounsaturated fat is in nuts, nut oil, avocado, olives and olive oil
