What food groups release energy?
Fats + Carbs
1 of 25
What do fats do?
Release energy, make cell mebranes
2 of 25
Why do we need protien in our diet?
For growth, cell repair + cell replacement
3 of 25
What is the role of fibre in our diets?
To keep everything running smoothly thorugh your digestive system
4 of 25
Why do we need tiny amounts of vitimans + minerals?
For healthy functioning of the body
5 of 25
What is your metabolism?
Chemical reactions that keep you alive
6 of 25
What is your metabolic rate?
The rate at which all the chemical reactions in the cells of the body are carried out
7 of 25
Do people with a higher proportion of fat to mucsle in their bodies have higher or lower metabolic rates + why?
Lower as muscle needs more energy than fatty tissue
8 of 25
Do physically bigger people have higher or lower metabolic rates + why?
Higher as the bigger you are thee more energy your body needs to be supplied with (because you have more cells)
9 of 25
Who has a higher metabolic rate - a man or a woman?
A man - slightly bigger + larger proportion of muscle
10 of 25
What can boost your resting metabolic rate + why?
Exercise - builds muscle
11 of 25
What factors effect your resting metabolic rate?
Proportion of muscle to fat in the body, amount of exercise and other physical activity, age, gender and inherited factors
12 of 25
What happens when you exercise (talk about metabolic rate)?
You need more energy - metabolic rate goes up during excercise + stays high for some time after
13 of 25
How does your activity level effect your diet?
It affects the amount of energy your diet should contain
14 of 25
What does malnourished mean?
People whose diet is badly out of balance are malnourished
15 of 25
What food groups eaten in excess can lead to obesity?
Fats + carbs
16 of 25
What is obesity?
It's defined as being 20% (or more) over max recommened body mass
17 of 25
What causes obesity?
Overeating, lack of exercise, bad diet + hormonal problems
18 of 25
What health problems can arise as a result of obesity?
Arthritis, type 2 diabetes, high blood pressure, heart disease + risk factor for some kinds of cancer
19 of 25
What can too much saturated fat in your diet do?
It can increase your blood cholestrerol level
20 of 25
What can eating to much salt lead to?
It can cause high blood pressure + heart problems
21 of 25
What are some of the effects of malnutrition?
Slow growth (in children), fatigue, poor resistance to infection + irregular periods of women
22 of 25
What does a lack of vitimans + minerals cause?
Deficiency diseases
23 of 25
What is scurvy + what causes it?
Lack of vitiman C - scurvy can cause problems with the skin, joints + gums
24 of 25
How does exercise help keep you healthy?
It increases the amount of energy used by the body + decreases the amount stored as fat, it builds muscle so it helps boost your metabolic rate
