A dietician recommended that a breakfast should be within the folloing limits for carbohydrates (CHO), fat and energy

Breakfast CHO (g) Fat (g) Energy (kJ)

Minimum 100 20 2400

Maximum 120 25 3000

I must choose one serve of each from each of the four groups of the following menu.

Food Group Serve CHO (100-120g) Fat (20-25g) Energy (2400-3000 kJ)

FRUIT

1 Apple 15g 0g 250kJ

1 Banana 28g 1g 500kJ

JUICE

Apple Juice 26.5g 0g 420kJ

Orange Juice 19g 0g 360kJ

Tomato Juice 9g 0g 195kJ

CEREAL (with milk)

Bonzo Bram 32.5g 1.5g 490kJ

Breaky Bix 26g 1.9g 600kJ

Sporty Crunch 35g 3g 750kJ

Porridge Plus 29g 8g 870kJ

EXTRAS

Eggs & Bacon 2g 26g 1300kJ

Omelette 0g 17g 900kJ

Baked Beans 30g 18g 1600kJ

Toast & Spread 50g 3g 850kJ

Questions

1. Explain why Baked Beans is the ONLY possible choice from the EXTRAS group.

2. Explain why Jake amy not choose Porridge Plus from the CEREALS group.

3. Determine Jake's complete breakfast selecttion and explain why it is the only possible choice.

Good Luck!

Apple, O.J., Bonzo Bran w/ raisins, toast and tofu spread.

porridge is too low in carbs. Too high in energy. not a very good mix cept for goldy lox.

because they are high in fiber very important for ones nutrition. Digestion is another story.

The apple can be substituted with a pear or a banana.

[akaslickster]

The bran can be substituted with a halibut. Yummmm! Extra lemon with that please.

only one person has geused

Where's the yogurt? Yogurt is really good for a healthy breakfast.

Negative 4 stars for another stellar riddle!!! (don't trip on the sarcasm)

[Guest]

banana, OJ, bonzo, and beans

[Guest]

it cant be the egga because already it is too high in fat... it cant be the toast as there is only 3g of fat, and cannot get enough from the others, same with the ommlette and CHO, the max would be 87... therefore it must be the beans

because we are having the baked beans with 18g we cant have anything with over 7g of fat in, so porridge is out

part 3

banana, orange juice, Bonzo bram (whatever that is?) and the beans

[Guest]

Can't be eggs & bacon ... too high in fat (already over 25) and not enough carbs (no way to get to minimum of 100)

Can't be omlette ... not enough carbs (no way to get to minimum of 100)

Can't be toast & spread ... not enough fat (no way to get to minimum of 20)

With needing to have baked beans and porridge, there's only one combination that's under 3000 energy ... having also an apple and tomato juice.

This would give you only 83 carbs, so there is no way to have over 100 carbs and under 3000 energy with porridge.

Also (and I'm writing this last only because I saw it after I wrote the previous answer), beans and porridge together have over the maximum of 25 grams of fat.

With baked beans, you already have 18 grams of fat, meaning you can only have between 2 and 7 more.

This means that sporty crunch is ok with everything, and the other two cereals are only ok with a banana.

Breaky Bix, beans, a banana and a juice doesn't work. Tomato juice doesn't have enough carbs to reach 100, and the other two will give you more than 3000 energy.

Sporty Crunch and beans have LOTS of energy ... 2350 already to be exact. Having a banana or apple juice will push energy over 3000 regardless of the other choice. Sporty Crunch and beans DON'T have a lot of carbs ... only 65 g. The highest remaining items (apple and orange juice) only push carbs to 99.

Bonzo Bran, beans, a banana and a juice only works with orange juice

---CARBS: 32.5+30+28+19 = 109.5

---FATS: 18+1.5+1+0 = 20.5

---ENERGY: 1600+490+360+500=2950
