Distinguish between/among a nutrient, an essential nutrient, a phytonutrient
and a nutraceutical and give an example of each:
Ans
✓ ● 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)
✓ ● Essential Nutrient: A nutrient of which food is the only or primary source; the BODY
CAN'T MAKE IT OR MAKE ENOUGH OF IT (ex: vitamin c; scurvy caused by deficiency)
✓ ● Phytonutrient: Compounds found in 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 NATURALLY FOUND IN FOOD OR PUT INTO FOOD that
may PREVENT OR TREAT diseases; probiotic aka BACTERIA
Identify the 2 major categories of essential nutrients, explains the basis for
their classification, and list their members:

✓ ● Approximately 45 NUTRIENTS
✓ ● Macronutrients: Present in the body in LARGE AMOUNTS, daily requirements that are
relatively large, present in food in relatively large amounts
✓ ● Large? Measured in grams; 28 G PER OUNCE
✓ ● Members? Protein, carbohydrates, lipids (fats), water
✓ ● Water CAN'T PROVIDE ENERGY (exception)
✓ ● Micronutrients: Present in the body in SMALL AMOUNTS, daily requirements that are
relatively small, present in food in relatively small amounts
✓ ● Small? MILLIGRAM (mg)= 1/1000thg MICROGRAM (mcg)= 1/1000000thg
✓ ● Members? Vitamins, minerals
Explain what a calorie represents, list the number of calories provided by a
gram of carbohydrate, fat, protein and alcohol, and calculate the total calories
of a food knowing its macronutrient content:

✓ ● Represents the ENERGY CONTENT of a food
✓ ● Calorie/kilocalorie
✓ ● Unit of heat equal to amount OF ENERGY NECESSARY TO RAISE 1,000G OF WATER
BY 1 DEGREE C
✓ ● Calorie content of a food? Measures POTENTIAL ENERGY within its components
macronutrients; energy RELEASED FROM MACRONUTRIENTS TO FUEL METABOLIC
PROCESSES
✓ ● Carbohydrates: 1g= 4 cal
✓ ● Protein: 1g= 4 cal
✓ ● Fat: 1g= 9 cal
✓ ● Ethanol (alcohol): 1g= 7 cal
✓ ● Total calorie content? MULTIPLE # of grams by amount of calorie per gram (above values)
and ADD for total
Define deficient, marginal, over-consumption and excess; identify the type of
effect that results from each level of intake; the effect itself; the time for
development; the nutrients of greatest concern at each level; and the levels of
intake most likely to occur in the US:
