this is for boy scouts but i dont understand the questions.
Your body is a machine. A very complicated one. Like all machines in needs fuel to operate. Different parts of the body need varying types and amounts of fuels. Nutrients are these fuels. To be physically fit all these parts must work properly or the machine breaks down and can’t operate. Another part of personal fitness is hygiene. You gotta clean the machine. Think of the body as an automobile. It needs regular maintanance an it’s your job to see that it gets it.
I was a boy scout myself. nutrition is what fuels your body for activity. you need it to stay healthy and to use as energy.
if you want any more help send me a message
