How many calories are in a food that contains
.100 grams of CHO
. 20 grams of protein
. 20 grams of fat
To determine the number of calories in a food item, we need to know the caloric content of each macronutrient (carbohydrates, protein, and fat). Here's how we can calculate the calories:
1. Carbohydrates (CHO): Each gram of carbohydrates provides 4 calories. We have 0.100 grams of CHO, so we multiply this by 4 to get the calorie content from carbohydrates.
0.100 grams CHO × 4 calories/gram = 0.4 calories from carbohydrates
2. Protein: Each gram of protein also provides 4 calories. We have 20 grams of protein, so we multiply this by 4 to get the calorie content from protein.
20 grams protein × 4 calories/gram = 80 calories from protein
3. Fat: Each gram of fat provides 9 calories. We have 20 grams of fat, so we multiply this by 9 to get the calorie content from fat.
20 grams fat × 9 calories/gram = 180 calories from fat
Now, to find the total number of calories in the food item, we add the calories from carbohydrates, protein, and fat together:
Calories from CHO + Calories from protein + Calories from fat = Total Calories
0.4 calories + 80 calories + 180 calories = 260 calories
Therefore, a food item that contains 0.100 grams of CHO, 20 grams of protein, and 20 grams of fat would have approximately 260 calories.
