Introduction
• This presentation aims to provide
guidelines on how to eat a balanced diet,
as well as evaluating the healthiness of
the food of the Western Food Store in our
school.
• Although a balanced diet is essential for
people at a growing age, most teenagers
do not actually care about having a
balanced diet.
Target
• Target: Students in Sport CCAs
• Examples include: Track and Field, Cross
Country, Gymnastics, Canoeing, Water Polo,
Basketball
• Aim: Provide them with
enough calories and proteins
• Needs for a meal :
• 220g carbohydrates
• 220g proteins
• 110g fats
Canteen Food Stall
• We have decided to choose the Western
Stall in our canteen for our analysis of
foods.
• The table on the next slide shows the
nutritional value of some foods that are
sold in the canteen stall.

Analysis
• Clearly, this is not enough to meet the
needs of the high energy consumption
sportsmen in our schools, as it is lacking
in protein, fats and carbohydrates. Thus,
we have resolved to create our own meal,
to meet the optimum amount of nutrients
that they need.
Designated Meal
• We have came up with a meal that has
higher nutritional value. It consists of
Murtabak with Sardine, Sweet and Sour
Commercial sauce, and 2 servings of
spring chicken in BBQ.

Designated Meal
• Meal fits the requirement of having
carbohydrates and fats
• Although lacking a little in protein
• Still much more nutritional value than the
foods in the Western stall
Cost of Meal
• Possible Cost of Murtabak with Sardine: $2
Sweet and Sour Commercial sauce: $0.50
• 2 servings of spring chicken in BBQ: $2.50
• The possible cost of the meal that we have
created will cost around 4 to 5 dollars. It may
seem expensive, but weighing the pros and
cons, the meal that we have created is
definitely much more desirable even though
the cost is slightly higher.
Benefits
• Most sportsmen might cite the problem of
high cost, however it is actually more
economical to buy this meal than buying
multiple servings just to meet the optimum
energy intake for sportsmen.
Furthermore, if compared to other places
such as in food courts, the price is
actually rather effective.
Benefits
• Even if the student is not a sportsman, it
can also help the student in more ways
than one. For example, lack of nutrients in
food will cause one to be weaker, and
therefore more prone to sicknesses. It
may also help in concentrating and
focusing during lessons, due to sufficient
intake of nutrients.
Conclusion
• The Western Store’s food does not serve
very nutritious food, and therefore eating
at these store may not be ideal for
sportsmen.
• However, it is still possible for sportsmen
to have their ideal meal but they may
have to fork out a bit more money.
