● Nutrient: Provides NOURISHMENT
● Non-essential Nutrient: A nutrient
found in food but it doesn't have to be;
our BODIES CAN MAKE IT (ex:
cholesterol; made in liver)
Distinguish ● Essential Nutrient: A nutrient of which
between/among a food is the only or primary source; the
nutrient, an essential BODY CAN'T MAKE IT OR MAKE
nutrient, a ENOUGH OF IT (ex: vitamin c; scurvy
phytonutrient and a caused by deficiency)
nutraceutical and give ● Phytonutrient: Compounds found in
an example of each: food that aren't NECESSARY FOR
LIFE/GROWTH BUT MAY PROTECT
AGAINST CERTAIN DISEASES; found in
FRUITS
AND VEGETABLES (ex: lutein, lycopene,
clorophyl)
● Nutraceutical: Compounds
