Macrominerals are needed in large amounts.
- magnisum
Trace minerals are needed in very small amounts.
- iron

Identify and know the difference between water soluble and fat soluble vitamins
Water-soluble vitamins (mainly B and C) are dissolved in the water in your body. They are easily lost (ie through urine) and need to be replenished often.
Fat-soluble vitamins (vitamins D, A, E, and K) are absorbed along with the fats you eat
8 B VITAMINS
Water Soluble
Converts food to energy
Make red blood cells
Nerve function
New cell creation
Makes DNA
Diarrhea
Inflamed intestines
Nervous system problems
Dairy
Meat
Eggs
Bananas
Fish
C
Water Soluble
Acts an an antioxidant
Helps make new cells
Supports the immune system
Scurvy (bleeding gums, loss of teeth)
Oranges
Peppers
Broccoli
Spinach
A
Fat Soluble
Supports healthy vision
Supports cell reconstruction and reproduction
Night blindness
Carrots
Pumpkin
Sweet potatoes
Oranges
D
Fat Soluble
The “sunshine vitamin”
Supports bone density
Helps form bones and teeth
Rickets; soft or brittle bones
Egg yolk
Fish
Liver
Sunlight
E
Fat Soluble
Acts as an antioxidant to fight disease in the body
Helps stabilize cell membrane
Nerve and muscle damage
Nuts
Avocado
Kiwi
Eggs
K
Fat Soluble
Helps clot blood
Susceptibility to bleeding; inability for wounds to clot
Leafy greens
Pumpkins
Broccoli
Brussel sprouts
How many vitamins does the body need
Know that there are 13 vitamins total the body needs
Fats
9 calories per gram of fat
Know that fat is the most concentrated source of food energy
2 forms of fat – Liquid and solid
No more than 30% of total daily calories should come from fat
Know and explain the functions of fat
Supplies Energy
Carries Vitamins A, D, E and K through the body
Provides a reserve store of energy
Promotes healthy skin
Promotes normal cell growth
Acts like a “cushion”and heat regulator to protect your heart, liver and other vital organs
It helps you feel full longer
Adds flavor to food
Protein
4 calories per gram of protein
Amino acids → molecules that combine to form proteins
20 total amino acids that the body needs
Main Functions of Protein
Energy: protein is metabolized into glucose by the body, which we use as energy.
Protein manufactures enzymes used in the carry out of cell processes
Building material: without this nutrient, your muscles and body wouldn’t be repaired properly, especially after a workout.
Antibodies: these are made up of proteins in the first place. So by eating more protein, you will be protected when unwanted substances enter your body.
Regulates fluid, electrolyte, acid and base balance
Explain one example of complete and incomplete protein
complete
contains all the essential amino acids in the amount required
Food Sources:
meat, fish, poultry, cheese, eggs and milk
soybeans, quinoa, spinach
incomplete
plant proteins are of lower quality (ie. lack enough of one or more essential amino acids)
Protein Combining
grains + legumes = complete protein
important for vegetarians
What is a carbohydrate?
sugar molicules
Identify and explain the two types of carbohydrates → simple and complex
Simple carbohydrates are made up of one f two sugars
found in fruits,milk and candy
complex carbohydrates are made up of muliple sugar molecules and are found in foods such as grains,potatoes and beans.
