For young adulthood ages nineteen to thirty, what is the AMDR for carbohydrates as a percentage of daily calories?
None of the above
10 to 35 percent
45 to 65 percent
20 to 35 percent
The Correct Answer is C
A. “None of the above” is incorrect because the correct range for carbohydrate intake is listed among the options.
B. The range of 10 to 35 percent corresponds to protein intake, not carbohydrates.
C. The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates for young adults (ages 19 to 30) is 45 to 65 percent of total daily calories. This range ensures adequate energy for daily activities, supports proper brain function, and provides dietary fiber for digestive health. Carbohydrates are the body’s primary energy source, and maintaining intake within this range helps prevent both nutrient deficiencies and excessive weight gain.
D. The range of 20 to 35 percent corresponds to fat intake, not carbohydrates.

Correct Answer is B
Explanation
A. Magnesium is essential for bone development, muscle function, and enzyme activity, but deficiency in young children is relatively uncommon in comparison to iron deficiency.
B. Iron deficiency is the most common nutrient deficiency in young children worldwide. Iron is crucial for the formation of hemoglobin, which carries oxygen in the blood, and for proper cognitive and physical development. Inadequate iron intake can lead to iron-deficiency anemia, causing fatigue, pallor, delayed growth, and impaired learning. Young children are especially at risk due to rapid growth and high iron requirements, combined with diets low in iron-rich foods such as meat, beans, and fortified cereals.
C. Folate (vitamin B9) deficiency can occur, especially in pregnant women, and may lead to anemia and neural tube defects in the fetus, but it is less common in young children than iron deficiency.
D. Vitamin C deficiency, which can cause scurvy, is rare in young children today because most diets include sufficient fruits and vegetables. While important for collagen synthesis and immune function, vitamin C deficiency is not the most common nutrient deficiency in this age group.
Correct Answer is A
Explanation
A. A normal BMI is defined as 18.5 to 24.9 kg/m². BMI is a screening tool used to assess body weight relative to height and estimate body fat. Values within this range are associated with a lower risk of weight-related health problems, including cardiovascular disease, diabetes, and certain metabolic disorders.
B. A BMI of 40 kg/m² is classified as class III obesity (severe or morbid obesity). Individuals in this range are at high risk for multiple health complications, including heart disease, hypertension, and type 2 diabetes.
C. A BMI of 25 to 29 kg/m² falls into the overweight category. While not as severe as obesity, being overweight still increases the risk of metabolic and cardiovascular conditions.
D. A BMI of less than 18.5 kg/m² is considered underweight. Being underweight can indicate malnutrition, eating disorders, or underlying medical conditions and is associated with increased risk for anemia, osteoporosis, and impaired immune function.
