Dr Dabour Hub Science Diagram and Course Material
Eat more fruit and vegetables and fewer fatty, sugary foods
Eat more protein foods, as he has too little protein
Cut out all starchy foods, since they cause weight gain
Eat more dairy and fatty foods so they match each other

Lina recorded the energy in everything she ate on a typical school day (bar chart). Her daily energy need is 10 000 kJ. Which conclusion is correct?
Dr Dabour Hub Science Diagram and Course Material
She took in 1500 kJ less than she needs, so should eat more snacks
She took in 1500 kJ more than she needs; cutting snacks would help
She took in exactly 10 000 kJ, so her energy intake is balanced
Her dinner alone gives more energy than she needs in a whole day
8.

Dr Dabour Hub Science Diagram and Course Material
Keep the rice and chicken, add steamed vegetables, swap cola for water
Double the fried chicken and keep the cola, for extra protein and energy
Remove the rice and chicken and eat only a bowl of fruit instead
Swap the rice for chips and add a second glass of cola for more energy
9.
Using the table, which is the best evaluation of the two lunchboxes?

Both are equally balanced because each contains some carbohydrate
B is worse because it has less fat, and fat is the most needed nutrient
B is better balanced: more protein, fibre and vitamin C, less sugar
10.

Brand X: it has 1.0 g less fat in every pot than Y
Both pots contain the same mass of fat, 4.0 g each
14.
Ruby wants to compare how many portions of fruit and vegetables Grade 7 and Grade 9 students eat. Which plan would give the most reliable results?

Ask 30 students in each grade to keep a food diary for a week
15.
Why is it fairer to compare two cereals using the "per 100 g" column of their labels rather than the amount in each packet?
Per 100 g values always show more energy than packet values
Packets differ in mass; per 100 g compares equal amounts
The packet amount is only for the fibre, not the other nutrients
Labels are only accurate for exactly 100 g of any food
