7. Food Sources
LS (Unit 2) Health, safety and training 2.2: Diet

8. Task 3: Carbohydrates Why are there important?
Provides quick energy. 60% of our diet should comprise 'carbs'.
Useful source of energy in...
Running - Athletes in training will eat more 'carbs'. Marathon runners will 'load' before the event.
Example foods: Pasta, Cereals, Potatoes
LS (Unit 2) Health, safety and training 2.2: Diet

9. Task 4: Protein Why are they important?
Builds and repairs muscle. We only need 15% of our diet to be protein.
Useful source of energy...
When training hard and recovering from injury. ‘Power’ athletes (weight lifters) will eat more protein.
Example foods: Meat, Pulses, Fish
LS (Unit 2) Health, safety and training 2.2: Diet

10. Task 5: Fats Why are they important?
Provides slow energy. 25% of our diet should be fat.
Useful source of energy in...
Walking and low impact exercise - it produces energy too slowly to be used when working hard.
Example foods: Oils, Dairy products (milk, butter, yogurt, cheese, etc) Nuts, Fish
LS (Unit 2) Health, safety and training 2.2: Diet

11. There are two types: Water-Soluble
Task 6: Vitamins
Why are they important?
Helps the body work. Helps concentration.
Useful source for...
Staying calm, making quick decisions.
Example foods: Fresh fruit and vegetables.
There are two types: Water-Soluble
and
Fat-Soluble
List of vitamins, reasoning & sources.
A - for vision (sweet potato with peel, carrots, spinach)
B - for energy production and stress reduction (whole unprocessed foods)
C - to keep skin healthy (citrus fruits)
D - to help bones and teeth (Fish liver oils, fatty fish, fortified milk products, sunlight exposure)
LS (Unit 2) Health, safety and training 2.2: Diet

12. Task 7: Minerals Why are they important?
Helps release energy from food. They are needed for healthy bones and teeth.
Useful for...When training hard and competing
Example sources: Fruit, vegetables and fish
LS (Unit 2) Health, safety and training 2.2: Diet

13. Task 8: Water (liquids)
Why are they important? Maintains fluid levels, whenever you sweat, lost liquid needs to be replaced.
Useful for...Preventing dehydration!
Example sources: The tap! Lettuce, Water Melon, Cucumber
It's all you need most of the time. Coca-Cola/Fanta/Aquarius BUT THESE ARE MORE THAN A LIQUID!
Drink before, during and after an event
LS (Unit 2) Health, safety and training 2.2: Diet

14. Task 9: Fibre
Why are they important? Can't be digested. Fills you up and keeps you 'regular‘.
Useful for...Healthy digestion, (no constipation) helps in sport. Also helps with weight control.
Example sources: Fresh fruit, vegetables and wholegrain cereals

15. Learning Objectives Diet Lesson 2:
Understand the different energy needs of: teenagers compared with young children, male manual workers and females, athletes and non-athletes, people with active lifestyles compared with people with sedentary lifestyles.

16. Energy
Requirements
LS (Unit 2) Health, safety and training 2.2: Diet

17. BMR + PAL = daily energy requirement
Task 10: Daily intake
Daily intake can vary from person to person based on two factors:
BMR (Basal Metabolic Rate)
The amount of energy it takes for your body to remain alive (even whilst sleeping/sitting).
PAL (Physical Activity Level)
The amount of energy the body needs to fuel activity.
The bigger the person, the bigger the BMR (child vs adults / male vs female)
The more active the person, the bigger the PAL (athlete vs non-athlete).
BMR + PAL = daily energy requirement
By consuming the same amount of energy as expelling for a day, the energy requirements are BALANCED.
LS (Unit 2) Health, safety and training 2.2: Diet

18. Anorexic BMR vs Normal BMR
LS (Unit 2) Health, safety and training 2.2: Diet ?

19. Task 11: Daily intake BASIC INFO:
1 calorie can heat 1g of water by 1ºC.
1kcal = 1000 calories (easier form of reporting)
If a person consumes more or less energy than the body requires, the energy requirements are UNBALANCED.
An adult male needs approximately 2500kcal / day.
An adult female needs approximately 2000kcal / day.
Consuming less kcal vs energy usage = weight loss.
Consuming more kcal vs energy usage = weight gain.
Being overweight may not be a problem! May be due to having a lot of muscle (rugby players for example), so it's not always harmful.
However, people who are overfat or obese will not be effective sportspeople.

20. Group Task: is the lady obese, overfat or overweight?
Overweight for a female, why?
LS (Unit 2) Health, safety and training 2.2: Diet

21. So how do you maintain a healthy, balanced diet?
LS (Unit 2) Health, safety and training 2.2: Diet

22. Task 12: Modern Methods of Reporting
In the UK, alongside the complicated nutritional information on the back of the packaging, it's now a requirement to show colour coded information on the front
THINK OF SOME REASONS WHY THIS FORMAT IS NOW A FAVOURED FORM ON REPORTING NUTRITIONAL INFORMATION

29. Task 14 - Diets for Different Sportspeople
Fill in the blanks, using the appropriate word
A person’s diet depends on the sport in which they participate.
Carbohydrates – Important for performers requiring energy for long periods e.g. ________________. Carbohydrate loading is a method used to increase your body’s carbohydrate stores before a competition so that you have plenty of energy.
Method:
4 or 5 days before an event, athletes will eat large amounts of _____________ and reduce the intensity of their _________.
This builds up the body’s __________ stores.
This method therefore reduces levels of fatigue during the event
