AMDR The Acceptable Macronutrient Distribution Ranges indicate ranges of carbohydrate, fat, and protein intakes that provide adequate amounts of vitamins and minerals and may reduce the risk of diet-related chronic diseases. For a person who is following a 2,500- kilocalorie per day diet, determine the number of grams of each macronutrient to be consumed using the AMDR as a guideline, and match it with its macronutrient category: Carbohydrate: Protein: Fat: 280-400 grams 56-97 grams 63-218 grams
The Correct Answer and Explanation is:
The Acceptable Macronutrient Distribution Ranges (AMDR) provide guidelines for carbohydrate, protein, and fat intakes to ensure that individuals are consuming a balanced diet. The ranges are given in grams and percentages of total daily energy intake. The following steps can be used to determine the number of grams of each macronutrient for a 2,500 kilocalorie per day diet:
1. Carbohydrate
- The AMDR recommends that carbohydrates contribute between 45% to 65% of total daily calories.
- For a 2,500-calorie diet:
- 45% of 2,500 calories = 1,125 calories
- 65% of 2,500 calories = 1,625 calories
- Since each gram of carbohydrate provides 4 calories, divide the calorie range by 4:
- 1,125 ÷ 4 = 281.25 grams
- 1,625 ÷ 4 = 406.25 grams
- So, the recommended range for carbohydrates is 280–400 grams, which aligns with the AMDR for carbohydrates.
2. Protein
- The AMDR recommends that protein contribute between 10% to 35% of total daily calories.
- For a 2,500-calorie diet:
- 10% of 2,500 calories = 250 calories
- 35% of 2,500 calories = 875 calories
- Since each gram of protein provides 4 calories, divide the calorie range by 4:
- 250 ÷ 4 = 62.5 grams
- 875 ÷ 4 = 218.75 grams
- So, the recommended range for protein is 56–97 grams, which aligns with the AMDR for protein.
3. Fat
- The AMDR recommends that fat contribute between 20% to 35% of total daily calories.
- For a 2,500-calorie diet:
- 20% of 2,500 calories = 500 calories
- 35% of 2,500 calories = 875 calories
- Since each gram of fat provides 9 calories, divide the calorie range by 9:
- 500 ÷ 9 = 55.56 grams
- 875 ÷ 9 = 97.22 grams
- So, the recommended range for fat is 63–218 grams, which aligns with the AMDR for fat.
In conclusion, the given macronutrient ranges match their respective categories:
- Carbohydrates: 280–400 grams
- Protein: 56–97 grams
- Fat: 63–218 grams
