Worked Example: Calculating Energy Content of Cereals Pulses Fibers

Understanding how to calculate the energy content of food sources is essential for both academic study and practical applications. The Atwater system provides a standardized method for estimating energy content based on macronutrient composition. Let’s examine a practical example using brown rice, a common cereal source.

Consider 100 grams of brown rice with the following composition:

Component	Amount (g)	Atwater Factor (kcal/g)	Energy Contribution (kcal)
Carbohydrates	70	4	280
Protein	5	4	20
Fat	2	9	18

The total energy content is calculated by summing the contributions from each macronutrient:

Total Energy = (Carbohydrates × 4) + (Protein × 4) + (Fat × 9)

Substituting the values:

Total Energy = (70 × 4) + (5 × 4) + (2 × 9) = 280 + 20 + 18 = 318 kcal

Therefore, 100 grams of brown rice provides approximately 318 kilocalories of energy. This calculation method applies universally to all cereals pulses fibers sources, enabling accurate nutritional assessments.

Mastering such calculations is crucial for HPSC Assistant Professor examinations, where questions often test practical application of theoretical knowledge.
