The formula to calculate the energy from protein is:
\[ E = P \times 4 \]
Where:
Energy from protein refers to the amount of energy, measured in kilocalories (kcal), that is derived from the protein content in food. Each gram of protein provides approximately 4 kcal of energy. This calculation is important for understanding the nutritional value and energy contribution of protein in a diet.
Let's assume the following value:
Using the formula to calculate the energy from protein:
\[ E = 50 \times 4 = 200 \]
The Energy from Protein (E) is 200 kcal.
