BYU HEALTH EDUCATION UNIT 2 NUTRITION AND PHYSICAL
ACTIVITY EXAM QUESTIONS AND ANSWERS #6
What do skin and hair need? - correct answer need fat to stay healthy
Thyroid gland - correct answer uses iodine to make hormones that govern metabolic
rate (affects things like body weight, energy levels, body temp.)
Iodine - correct answer needed to keep the thyroid gland healthy and functioning; body
also uses iodine to get energy from food (a lot of salt is "iodized"), but this mineral is
naturally in seafood and dairy
Muscles need... - correct answer need protein to build themselves up and calcium to
contract
Calcium - correct answer gives bones and teeth strength; required by muscles and
blood vessels to contract; found in dairy products, leafy vegetables, and certain fish
Potassium - correct answer helps regulate your heartbeat; aids nerve and muscle
function; found in leafy green veggies, vine growing fruit, carrots, potatoes, and citrus
fruits
Zinc - correct answer enables the sense of smell and taste; aids immune system,
wound healing, and cellular function; found in protein sources and sometimes in
medicines like nasal sprays
Phosphorus - correct answer required for formation and strengthening of teeth and
bones (like calcium); involved in nerve signaling and kidney function; found in meat,
milk, and whole grains
B vitamins - correct answer help metabolism; found in protein sources such as eggs,
beans, and poultry, leafy green vegetables; help create red blood cells
Vitamin c - correct answer helps your body absorb iron during digestion; needed for
wound healing (helps tissue repair); found in citrus fruits and red and green vegetables
Vitamin a - correct answer helps your vision; found in colorful plants (carrots) and in
whole milk and liver; aids cellular and immune functions
Vitamin d - correct answer helps bones become strong and stay strong; found in eggs
and other animal proteins, but is also made by the skin when hit with sunlight
Vitamin k - correct answer helps create proteins needed for blood clotting; found in
green veggies and dark berries
, Iron - correct answer carries oxygen throughout the body via blood vessels; found in
dark leafy greens, meat, and dried fruits
Water - correct answer makes up a lot of the blood; necessary to maintain adequate
blood pressure; regulates temperature of body and helps in the removal of waste
Effects of dehydration - correct answer lower blood pressure because there's not as
much fluid flowing through your vessels
Vitamins and minerals - correct answer help body grow, develop normally, and maintain
proper function; can be found in fruits and colorful vegetables, protein sources; many
foods are fortified with minerals and vitamins and one can also take supplements
(taking too many can result in harmful consequences)
Calorie definition - correct answer unit of energy that is stored in food; when one has
consumed more calories than one uses, their energy is stored for later use in one form
or another (such as fat); different types of food (carbs, proteins) have different caloric
values per gram
Carbohydrates - correct answer molecules used for energy; broken down into a simple
sugar molecule called glucose; found in fruit, veggies, pasta, rice, cereal, bread, and
sometimes dairy
Simple carbohydrates vs. Complex carbohydrates - correct answer simple
carbohydrates provide energy quicker than complex carbohydrates
Insulin - correct answer the "secret password" glucose needs to get into the cells of
certain tissues to be used for fuel; people with metabolic disorders (diabetes or insulin
related) must be conscious of the amount of sugar/carbs they eat for this reason
What happens when you eat too many carbohydrates? - correct answer excess energy
provided by carbohydrates is turned into fat within the liver and muscles; carbs break
down quickly into glucose; high glucose levels require high insulin levels; having high
insulin makes your body more resistant to it; can cause insulin resistance
Fats (lipids) functions - correct answer providing body with sustained energy, protecting
major organs, aiding in the absorption of vitamins and minerals, insuring proper brain
development, controlling immune responses, helping blood to clot, and providing
insulation
Where can one find fats? - correct answer nuts, fish, peanut butter, meat, milk, oils, and
butter
Proteins (where they can be found inside and outside the body) - correct answer
involved in almost every process/structure of the body; found in eggs, beans, legumes,
meat, dairy, tofu, nuts
