Questions: Determine total grams of protein and the percentage of kcalories from protein.

To determine the total grams of protein and the percentage of kcalories from protein in a meal consisting of beans and rice, we need to know the specific quantities of beans and rice being consumed and their respective nutritional information. For the sake of this example, let's assume the following:

• 1 cup of cooked beans (e.g., black beans) contains approximately 15 grams of protein and 227 kcal.
• 1 cup of cooked rice (e.g., white rice) contains approximately 4 grams of protein and 205 kcal.

Let's assume the meal consists of 1 cup of beans and 1 cup of rice.

1. Total Grams of Protein:

   • Protein from beans: 15 grams
   • Protein from rice: 4 grams
   • Total protein: 15 grams + 4 grams = 19 grams

2. Total Kcalories:

   • Kcalories from beans: 227 kcal
   • Kcalories from rice: 205 kcal
   • Total kcalories: 227 kcal + 205 kcal = 432 kcal

3. Percentage of Kcalories from Protein:

   • Each gram of protein provides 4 kcal.
   • Total kcalories from protein: 19 grams * 4 kcal/gram = 76 kcal
   • Percentage of kcalories from protein: (76 kcal / 432 kcal) * 100 = 17.59%

• Total grams of protein: 19 grams
• Percentage of kcalories from protein: 17.59%

This calculation shows that a meal consisting of 1 cup of cooked beans and 1 cup of cooked rice provides 19 grams of protein, and approximately 17.59% of the total kcalories in the meal come from protein.
