How much energy is produced if a person eats 50 g of digestible carbohydrate (not fiber) in a day? In this case, what percent of a 2200 Calorie diet would be digestible carbohydrate? Recall that carbohydrates provide four Calories of energy per gram consumed.

검증된 단계별 안내

Identify the amount of digestible carbohydrate consumed, which is 50 g.

Recall that carbohydrates provide 4 Calories of energy per gram.

Calculate the total energy produced by multiplying the grams of carbohydrate by the energy provided per gram: 50 g * 4 Cal/g.

Determine the total energy produced in Calories from the carbohydrates.

Calculate the percentage of a 2200 Calorie diet that the energy from carbohydrates represents by dividing the energy from carbohydrates by 2200 Calories and multiplying by 100.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Energy from Carbohydrates

Carbohydrates are a primary source of energy for the body, providing approximately four Calories per gram. When consumed, they are broken down into glucose, which is utilized by cells for energy. Understanding this conversion is essential for calculating the total energy produced from a given amount of carbohydrates.

Caloric Intake and Diet Composition

A typical diet is often measured in Calories, which represent the energy content of food. In this context, a 2200 Calorie diet serves as a reference point for evaluating the contribution of carbohydrates to overall energy intake. Knowing the percentage of calories from carbohydrates helps assess dietary balance and nutritional adequacy.

Calculating Percentages

Calculating percentages is a fundamental mathematical skill used to express a part of a whole. In this scenario, determining what percent of a 2200 Calorie diet is made up of the energy from 50 g of carbohydrates involves dividing the energy derived from carbohydrates by the total caloric intake and multiplying by 100. This calculation is crucial for understanding the role of carbohydrates in the diet.
