Fat contains Group of answer choices 9 calories or 37 kJ per gram 4 calories or 17 kJ per gram 4 calories or 37 kJ per gram 9 calories or 17 Kj per gram

To determine which option is correct for the caloric content of fat, let's examine the standard nutritional information regarding macronutrients:

1. Caloric Content of Macronutrients: In nutrition, grams of macronutrients provide certain amounts of calories:

   • Fat: Approximately 9 calories per gram
   • Carbohydrates: Approximately 4 calories per gram
   • Protein: Approximately 4 calories per gram

2. Energy Conversion: Additionally, each calorie can be converted to kilojoules (kJ) using the conversion factor: $1 \text{ calorie} \approx 4.184 \text{ kJ}$

Thus, if we look specifically at the energy provided by fat:

• Calories per gram of fat: 9 calories
• To convert to kJ: $9 \text{ calories} \times 4.184 \text{ kJ/calorie} \approx 37.68 \text{ kJ}$ This is usually rounded to 37 kJ per gram.

Final Answer

The correct choice is 9 calories or 37 kJ per gram.
