a girl is celebrating her 7th birthday. each guest is served one large slice of choclate cake, a hamburger, french fries, and some oranges.
identify the food groups mentioned above.
if one slice of chocolate cake contains 35g of carbohydrate, 15g of fat and 5g of protein, calculate the kilocalories that each slice of cake contains.
identify all the food groups that form a part of a balanced diet along with their sources.
carbo 4kc/1g 35g = 140 kcal
fat 9kc/1g 15g = 135 kcal
protein 4kc/1g 5g = 20 kcal
cake contains a total of 295 kilcalories
The food groups mentioned in the scenario are:
1. Chocolate cake: This falls under the "Sweets and Desserts" category, which is part of the "Empty-Calorie Foods" group.
2. Hamburger: This falls under the "Meat and Alternatives" category, which includes foods like meat, poultry, fish, eggs, tofu, beans, lentils, and nuts.
3. French fries: These fall under the "Grains and Starchy Vegetables" category, which includes foods like bread, rice, pasta, potatoes, and corn.
4. Oranges: Oranges fall under the "Fruits" category, which includes all types of fruits like oranges, apples, strawberries, bananas, etc.
To calculate the kilocalories (kcal) in each slice of chocolate cake, we need to consider the macronutrient composition. Each gram of carbohydrate and protein contributes 4 calories, while each gram of fat contributes 9 calories.
Carbohydrate: 35g x 4 kcal/g = 140 kcal
Fat: 15g x 9 kcal/g = 135 kcal
Protein: 5g x 4 kcal/g = 20 kcal
To calculate the total kilocalories:
Total kcal = Carbohydrate kcal + Fat kcal + Protein kcal
Total kcal = 140 kcal + 135 kcal + 20 kcal
Total kcal = 295 kcal
So, each slice of chocolate cake contains 295 kilocalories.
For a balanced diet, it is essential to include a variety of food groups in appropriate proportions. The major food groups that form part of a balanced diet are:
