Question

The Okinawan diet can be described as a low-energy, nutrient-rich, high-carbohydrate diet that may be beneficial for reducing the risk of many chronic diseases. The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrate is 45% to 65% of kcal. What percent of calories in this 1-day Okinawan diet menu come from carbohydrate? The amount of total carbs is 342.6 and the amount of total calories is 1790.5. (I wasn't provided with the amount of calories per gram of carbohydrate.)

Answer 1

The Percentage of calories of the Carbohydrate can be calculated by:

Step 1

To convert the carbohydrate from grams in to kilocalories, multiply the given gram in to 4 (Each gram of carbohydrate is equal to 4 kcal of energy)

The amount of carbohydrate in grams = 342.6

To convert to Kcal = 342.6 ×4

                               = 1370.4 Kcal of carbohydrate                              

Step 2

To calculate the percentage of kilocalories by:

Divide the kilocalorie obtained as result from the Step 1by the total amount of calorie given in the information

                        = 1370.4 Kcal ÷ 1790.5 Kcal

                        = 0.76

Step 3

Multiply the result of Step 2 × 100

                       = 0.76 × 100

                       =76 %

Hence, 76% of carbohydrate kilocalories are included in this diet menu.
