Nutritional Value
• The meal provides ample amount of energy and proteins, however it lacks vitamin C and fibre. It also contains a lot of fats as the chicken is deep fried hence a lot of oil is accumulated in the chicken.
Evaluation
• NPCC will get only get their calories and protein from the meal. Others like vitamin C and fibre are neglected. This are equally important, especially to a teen that is still under going growth.
Suggested Meal
• Rice
• Roasted chicken
• Potato
• Cauliflower
• Orange
• Milk

Suggested Meal
• Estimated Cost: $3 to $4• Roasted is the healthiest among
steam and deep fried etc (taken from hpb.gov.sg), hence we chose roasted chicken.
• The potato and cauliflower are to be boiled as boiling is much healthier den frying because it does not need to use oil.

Comparison
• Proteins now take up 3/4 of the recommended amount in one day
• Carbohydrates now take up ½ of the recommended amount in one day
• Vitamin C now take up 2/3 of the recommended amount in one day
Comparison
• Hence, our meal caters better to the NPCC cadets as they require lots of energy, protein and vitamins. Also, our meal does not neglect other nutritional values like calcium, iron and fibre
