Answer 1

1) i

1 scoop (1 serving) = 18 grams of protein (mentioned in the label)

3 scoops will include, 3 * 18 = 54 grams of protein.

2)

1 cup of of low fat milk contains 8.2 grams of protein

to get 54 grams of protein from the milk

So we have to divide 54/8.2 =6.56 times

we need to drink 6.56 cups of low fat milk.

3)

3.5 ounces of chicken breasts have 27 gram of protein

we need 54 grams

27 *2 =54

we need 3.5 * 2 = 7 ounces of chicken breast for 54 grams of protein

4)

the jar has 30 scoops

30 scoops cost 20 dollars,

so one scoop cost 30/ 20 = 0.66 dollar

3 scoops cost 2 dollars.

16 ounces of chicken breast cost 3 dollars,

we need 7 ounces which is 1.5 dollars.

So the milk and chicken are cheaper sources.

5) the supplements volume is much less compared to 7 ounces of chicken and 6.5 cups of milk compared to 3 scoops of the powder. Volume wise the supplement is much more convenient.

6) No there is no extra health risk for consuming 157 grams of protein. The recommended intake is 0.8 gram protein for a pound of body weight.

7) i would recommend paolo to consume the supplement to meet his protein needs.
