Nutrients: You Just Can’t Live Without ‘Em
Pages 20-23
1. What are nutrients and what are they used for? Nutrients fuel the
body to keep you going. Used for growth and repair and to fight
disease.
2. What are the 6 types of nutrients? Carbs, proteins, fats, vitamins,
minerals and water.
3. What are two types of carbs? Sugar, starch
4. What is the difference between a simple carb and a complex carb?
The body uses simple sugar called glucose. Complex carbs are called
starches. The body has to break complex carbs into simple carbs to
be able to use them.
5. What does our body do with extra glucose? It is turned into glycogen
and saved in the muscles and liver or turned to fat.
6. Why does our body store fat? To make sure it has fuel for future use.
7. What is fiber and what does it do for our bodies? Fiber is another
type of carb but it can’t be digested. It provides bulk that helps
move food through the digestive tract.
8. What foods provide fiber? Fruits, vegetables, whole grain breads and
cereals
9. What does our body do with proteins? Builds tissue, repairs damage,
makes hemoglobin, which carries O2 through your body.
10. What does our body break protein into? Amino acids
11. What are essential amino acids? Nine amino acids that our bodies can
only from the food we eat.
12. What are complete proteins and where do we get them? A complete
protein contains all nine of the essential amino acids. We get them
from food from animals (meat, eggs, milk)
13. What are incomplete proteins and where are they found? Foods that
do not have all nine essential amino acids are called incomplete
proteins. Foods from plants contain incomplete proteins (vegetables,
fruits, wheat, rice)
14. Is fat bad for you? Fat has more energy than proteins or carbs. Thin
layers of fat protect organs and insulate the body.
15. What are two types of fats and where do they come from? Saturated
and unsaturated. Most fats from animals are saturated (meat,
cheese, cookies, cakes). Most fats from plants are unsat. (fish,
avocados, liquid cooking oils)
16. What is the danger of eating too much fat? High cholesterol, which
accumulates within blood vessels, straining the heart.
17. What are vitamins and how do our bodies use them? Chemicals that
have been made by living organisms. Vitamins help build blood cells
and chemicals that control the nervous system.
18. Where are vitamins found? Fresh fruits and veggies
19. What are minerals and how do our bodies use them? Minerals are
chemicals that occur naturally in the environment. They help our
bodies build bones, teeth and blood cells. Also regulate chemical and
electrical signals that control the way our body works.
20. Where do minerals come from? The earth~ they are absorbed by
plant roots as they grow and are then passed onto us when we eat
plants/animals.
21. What are some examples of minerals? Copper, iodine, iron, zinc,
calcium, potassium, sodium
22. Why is calcium very important? Our bodies use it to build hard,
strong bones and teeth and keep bones strong.
23. Why is water so important? Every cell is packed with water to
transport nutrients and wastes, control your temp and carry chemical
reactions.
