The RDAs for most nutrients are
63 units
Dietary recommendations to prevent disease include all of the following except
?
Which of the following is characteristic of an essential nutrient
nutrients a person must obtain from food because the body cannot make them for itself in insufficient quantity to meet physiological needs; also called indispensable nutrients
Nutrient dense refers to foods that
rich in nutrients compared to their calorie content
During digestion
protein is broken down to Amino Acids, carbohydrate to Glucose, and fat to fatty acids and monoglycerides
The form of sugar important to the body as blood sugar is:
Glucose
Dietary Guidelines recommend that carbohydrate intake continue approximately what percent of the total caloric intake
?
All of the following are benefits of fiber except
Makes things easier to pass, prevents disease, and keeps weight under control
What is the function of bile?
Is produced by the liver, stored in the gall bladder, and acts as an emulsifier to suspend fat
you have once again just finished a light breakfast of toast and jelly. Which of the following series of events proceeds upon digestion/absorption of the meal until it is near time for lunch?
1. Blood Glucose rises
2. High blood glucose stimulates the pancreas to release insulin
3. Insulin stimulates glucose into cells & storage as glycogen in the liver and muscles
4. The body’s cells use glucose; blood levels decline
5.Low blood glucose levels stimulates pancreas to release glucagon into bloodstream
6. Glucagon stimulates liver cells to break down glycogen & release glucose into the bloodstream
7. Blood glucose begins to rise.

What compound is composed of 3 fatty acids and glycerol?
Triglycerides
In which form are most dietary lipids found?
Triglycerides
Lipids differ in their degree of saturation or unsaturation due to their number of
Double bonds
What type of fatty acid is found in high amounts in olive oil?
Monounsaturated fatty acid
An omega-3 fatty acid has its first double bond on the
3rd carbon away from methyl (CH3)
Which of the following is a feature of polyunsaturated fats?
Has two or more carbon-to-carbon double bonds. Lacks 4 or more hydrogen atoms. Composed of triglycerides. Ex (Linoleic acid)
All of the following are rich sources of polyunsaturated fatty acids
"on exam it says (except)"
Vegetable oils are rich ex. Safflower, flaxseed, walnut, sunflower, and corn oils.
Oil that is partially hydrogenated sometimes changes one or more of its double bond configurations
From
cis fatty acids to trans-fatty acids
Which of the following is an important chemical feature of phospholipids?
Phosphate & Fatty acids
What is the major sterol in the diet?
Cholesterol
Which of the following foods contains cholesterol?
From animals, Meats, eggs, Fish, and dairy products
What lipoprotein is largest in size?
chylomicrons
In comparison to a low-density lipoprotein, a high-density lipoprotein contains
primarily of protein
Each of the following is known to be linked to excessive intake of fats except
Cancer Obesity & Heart Disease
Your father has just come back from the doctor where he was subjected to a blood lipid profile analysis. The doctor provided him with dietary changes because the cholesterol results put him at increased risk for cardiovascular disease. Which of the following results is consistent with the diagnosis?
Excess cholesterol, restricting blood flow, and rising of blood pressure
According to the Dietary Guidelines, what should be the range of fat intake as a percentage of energy intake?
20-35%
In comparison to the composition of carbohydrates and fats, which element found in proteins makes
them unique?
Nitrogen
How many different kinds of amino acids make up proteins?
20
All of the following are contained in an amino acid except:
amino acids contain an amino group, an acid group
Which of the following is a feature of an essential amino acid?
Sometimes become non essential, & must be supplied by diet
What is meant by the amino acid sequence of a protein?
They vary
A non-essential amino acid is
one that the body can synthesize (or make)
Which of the following proteins inactivates foreign bacteria and viruses
Antibodies
Which of the following may be used to determine protein utilization?
Nitrogen Balance
Which of the following defines protein turnover?
The degradation & synthesis of proteins
What is the amino acid pool?
The supply of amino acids that are available
What is the fate of excess dietary protein?
Stored as fat
What is the usual state of nitrogen balance for healthy infants, children, and pregnant women?
Nitrogen is positive. This means the body synthesizes more than it degrades
Protein sparing in the body is best achieved when a person ingests
Carbohydrates
Which of the following is a consequence of excess protein intake?
It is degraded and stored as fat
A person who is starving is
low in nitrogen.
What is the percent digestibility of most animal proteins?
90-99%
Which of the following food proteins has the best assortment of essential amino acids for the human body?
Eggs
What primary factor that governs the quality of a food protein?
Amino acid contents & digestibility
What is a “limiting” amino acid in a dietary protein?
The one that is missing the amino acid
If the diet is lacking an essential amino acid, what will be the course of action?
Protein synthesis will be limited

What is complementary protein nutrition?
Combining Plant proteins to contain essential amino acids
What would be the primary principle of wise diet planning as related to protein nutrition?
Variety of different foods
Which of the following is a feature of the protein RDA?
0.8 g/kg/day
Which of the following is an assumption made in the formulation of the RDA for protein?
