You must pack food that has high concentrations of fat and protein. Food like granola bars and canned meat are a good source of energy and heat. This is because the body breaks this food down easily converting it into usable energy.

Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. But she is not worried too much sin

marysya [2.9K]

Explanation:

%DV label= 27%

1 cup of cooked collared greens= aprx 266.60 mg of Calcium

Assuming Clara is...

a teen, her required adequate intake (RAI)= 1300 mg/ day
an adult, her RAI= 1000 mg/day

For teenaged Clara

∵27 % DV= 270mg

% daily Calcium= $\frac{270}{1300} * 100=$ = 20.8 ≈ 21%

=0.21

<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>

Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
