Answer
The evidence that demonstrates a fair comparison is that both food A and food B have the same mass or grams, specifically 80 g of each. This ensures that the nutritional values are being compared on an equal basis.
Step 2
Which food, A or B, would be a better choice as part of a healthy diet? Use two pieces of evidence from the table to support your answer.

Answer
Food B is a better choice as part of a healthy diet. Two pieces of evidence from the table are:
Food B has less sugar compared to food A, which contributes to better overall health and less risk of diabetes.
Additionally, food B contains more protein, which is essential for muscle growth and repair.
Step 3

Answer
To calculate the percentage of protein in food A, we can use the formula:
extPercentageProtein=(total gramsgrams of protein)×100
Assuming food A contains 15 grams of protein in a total of 100 grams, the calculation would be:
(10015)×100=15%
Thus, the percentage protein in food A is 15%.
