TRANSCRIPT
OBJECTIVES Analyse the dietary needs of these students in the
aspect of Age group (13 years to 16 years) Level of activity Specific nutrition needed
Assessing the Yong Tau Foo Stall in our school for Nutritional value If it is adequate for discus throwers
Design a meal for these people in these aspects: Realistic More balanced nutrition compared to the Yong Tau
Foo Stall Costs
Compare the designed meal to the Yong Tau Foo Stall and state its benefits
BACKGROUND RESEARCH - CARBOHYDRATES
Best fuel sources for athletes Provides energy; initial fuel source
In short-burst, high intensity events such as sprinting, jumping as well as discus throwing, carbohydrates provide 100% of the energy
The body stores limited amounts of carbohydrates as glycogen
BACKGROUND RESEARCH - CARBOHYDRATES
Physical training and a diet rich in complex carbohydrates help athletes to store more glycogen and to use its limited supply sparinglyComplex carbohydrates come from food
such as: Spagahetti Potatoes Lasagna Cereals And other grain products
When glycogen supply runs low, athletes become fatigue and performance suffers
BACKGROUND RESEARCH - PROTEINS
Building blocks of the body Consists of amino acids that form muscles,
bones, tendons, skin, hair and other tissues Athletes need protein primarily to repair and
rebuild muscle that is broken down during exercise
Also help to optimize carbohydrate storage in the form of glycogen
Not an ideal source of fuel for exercise
BACKGROUND RESEARCH - FATS
Essential nutrient for optimal health Store fat provides cushion and insulation to
internal organs Moves Vitamins throughout the body Largest reserve of store energy available for
activity
BACKGROUND RESEARCH - FATS
Types of dietary fatsSaturated fats (Too much of these may
cause health problems) Meat Egg yolks Yoghurt Cheese Butter Milk
Unsaturated fats Usually found in plant food sources Brings health benefits Athletes should aim to eat more food containing more
unsaturated fats
BACKGROUND RESEARCH - MINERALS & VITAMINS
Minerals Inorganic elements that aid in the formation of
strong bones Cannot be made by the body; they are provided
by the food we eat Vitamins
Organic compounds that help regulate fat, carbohydrate and protein metabolism in the body
Cannot be made by the body; they are provided by the food we eat
Not an energy source, but play a vital role in releasing energy stored
DIETARY NEEDS
High carbohydrate intake to cope with training load About 1.4-2.0 grams of carbohydrates per kg of
body weight Normal intake of proteins
About 1.4-1.8 grams of proteins per kg of body weight
Normal intake of fats as well High intake of vitamins and minerals
Athletes should take in as much vitamins and minerals as possible

PROPOSED MEAL
Yong Tau Foo allows individuals to order the ingredients he wants Added in other kinds of food such as drinks to
complement the needs of the discus thrower Emphasis on carbohydrates and vitamins
Carbohydrates – main source of energy Vitamins – aid in releasing of energy
PROPOSED MEAL Orange/ Watermelon Juice (Optional)
Source of vitamins Bee Hoon
Main source of carbohydrates Laksa Soup
May be unhealthy, but provides both carbohydrates and vitamins
Dry Shrimp Dumpling Source of carbohydrates
Chinese Sausage Source of carbohydrates
Chocolates (Optional) High source of carbohydrates
PROPOSED MEAL
Total costs $1.50 + $0.50= $2.00(Without Orange Juice and
Chocolates)4 ingredients: $1.50Bee Hoon: $0.50Orange Juice: $1.00-$1.50
