4.3. Calculate Protein per Ingredient

• Multiply Protein Content: Multiply the protein content per serving by the number of servings used in the recipe for each ingredient.
  • For example, if 100 grams of chicken breast contains 30 grams of protein and you use 200 grams (2 servings), the total protein from chicken breast is 30 grams/serving * 2 servings = 60 grams.

4.4. Sum the Protein Content

• Add All Values: Add up the protein content from all ingredients to find the total protein in the entire dish.
  • For example, if your dish contains 60 grams of protein from chicken breast, 10 grams from vegetables, and 5 grams from rice, the total protein is 60 + 10 + 5 = 75 grams.

4.5. Determine Protein per Serving

• Divide by Number of Servings: If you want to know the protein content per serving, divide the total protein by the number of servings the dish yields.
  • For example, if the entire dish contains 75 grams of protein and makes 3 servings, each serving contains 75 grams / 3 servings = 25 grams of protein.

4.6. Example Calculation

Let’s calculate the protein content of a simple chicken salad:

• Ingredients:
  • 200 grams of cooked chicken breast
  • 50 grams of mayonnaise
  • 100 grams of celery
  • 2 slices of whole wheat bread
• Protein Content per Serving:
  • Chicken breast: 30 grams of protein per 100 grams
  • Mayonnaise: 1 gram of protein per 100 grams
  • Celery: 1 gram of protein per 100 grams
  • Whole wheat bread: 4 grams of protein per slice
• Calculation:
  • Chicken breast: (30 grams / 100 grams) * 200 grams = 60 grams
  • Mayonnaise: (1 gram / 100 grams) * 50 grams = 0.5 grams
  • Celery: (1 gram / 100 grams) * 100 grams = 1 gram
  • Whole wheat bread: 4 grams/slice * 2 slices = 8 grams
• Total Protein: 60 + 0.5 + 1 + 8 = 69.5 grams

Therefore, the chicken salad contains approximately 69.5 grams of protein.

4.7. Tips for Accuracy

• Use Precise Measurements: Accurate measurements are essential. Invest in a good kitchen scale and measuring cups.
