Question 2

Generally speaking, saturated fatty acids are contributed primarily by plant foods, whereas polyunsaturated fatty acids come primarily from animal foods

Accepted Answer

This statement is incorrect. Saturated fatty acids are primarily found in animal foods such as meat, butter, and cheese, whereas polyunsaturated fatty acids are found in plant foods such as nuts, seeds, and vegetable oils.

Question 3

Question 4

All fatty acids contain a methyl end, a carboxylic acid end, and a backbone composed of a carbon chain

Accepted Answer

This is true. Fatty acids are composed of a hydrocarbon chain with a methyl (CH3) end and a carboxylic acid group (COOH) at the other end. The carbon chain backbone can vary in length and degree of saturation.

Question 5

Given that the Daily Value for fat is 65 g.what percentage of the DV for total fat is provided by the following meal: 1 serving of Sunny Start cereal with 1 cup of milk, 1 bagel with 1 Tbsp cream cheese, and 1 cup of milk?
A)14
B)16
C)19
D)24

Accepted Answer

The answer of Given that the Daily Value for fat...

Question 6

Most naturally-occurring unsaturated fatty acids are trans fatty acids

Accepted Answer

Most naturally-occurring unsaturated fatty acids are cis fatty acids. Trans fatty acids are primarily created through industrial processes such as hydrogenation.

Question 7

Cholesterol is a fatty acid found in animal foods and made by the body

Accepted Answer

Cholesterol is not a fatty acid; it is a type of lipid or sterol that is indeed found in animal foods and synthesized by the body, but it is structurally different from fatty acids.

Question 8

If Gayla's energy requirement is 2100 kcal/day, and she eats an Oscar's bagel with 2 tablespoons cream cheese, how many more grams of saturated fat can she consume that day without exceeding the Dietary Guidelines recommendation?
A)5
B)19
C)36
D)174

Accepted Answer

The Dietary Guidelines recommend limiting saturated fat to less than 10% of total daily calories. For Gayla, whose energy requirement is 2100 kcal/day, this means she should consume less than 210 kcal from saturated fat (10% of 2100 kcal). Since fats provide about 9 kcal per gram, this translates to less than 23 grams of saturated fat per day (210 kcal ÷ 9 kcal/g). If an Oscar's bagel with 2 tablespoons of cream cheese contains approximately 4 grams of saturated fat, Gayla can consume 19 more grams of saturated fat (23 grams - 4 grams) without exceeding the recommendation.

Question 9

What percentage of the total kcalories is provided by fat in the following meal: 1 serving of Sunny Start cereal with 1 cup of milk, 1 bagel with 1 Tbsp cream cheese, and 1 cup of milk?
A)19
B)22
C)23
D)24

Accepted Answer

The answer of What percentage of the total kcalories is...

Question 10

Humans cannot eat synthesized fatty acids

Accepted Answer

Humans can eat synthesized fatty acids, and they are commonly used in the food industry as ingredients in processed foods.

Question 11

How many kcalories from fat are provided in 2 servings of Sunny Start cereal?
A)1
B)2
C)9
D)18

Accepted Answer

Each serving of Sunny Start cereal provides 9 kcalories from fat, so 2 servings provide 18 kcalories from fat.

Question 12

The typical American diet does not include foods rich in the essential fatty acids; therefore, a supplement is needed

Accepted Answer

The typical American diet often includes adequate amounts of essential fatty acids, particularly omega-6 fatty acids, due to the consumption of vegetable oils and animal products. However, it may lack in omega-3 fatty acids, which are also essential but can be obtained through specific dietary choices like fish, flaxseeds, and walnuts, rather than necessarily requiring a supplement.

Question 13

The Dietary Guidelines recommend that we consume less than _____ of cholesterol daily
A)100 mg
B)100 grams
C)300 mg
D)30 grams

Accepted Answer

The Dietary Guidelines recommend that we consume less than 300 mg of cholesterol daily. This helps to reduce the risk of heart disease, which can be caused by high levels of cholesterol in the blood. Consuming foods that are low in cholesterol and saturated fats, such as fruits, vegetables, whole grains, and lean proteins, can help us meet this guideline.

Question 14

Lipid is the most concentrated source of energy among the energy-yielding nutrients

Accepted Answer

Lipids, also known as fats, provide 9 calories per gram, which is more than double the amount provided by carbohydrates and protein (which both provide 4 calories per gram). Therefore, lipid is the most concentrated source of energy among the energy-yielding nutrients.

Question 15

The alpha end of a fatty acid is a methyl group

Accepted Answer

The alpha end of a fatty acid is the carboxyl group (-COOH), while the methyl group (-CH3) is found at the omega end.

Question 16

What percentage of the DV from trans fatty acids would you consume in the following meal: 1 serving of Sunny Start Cereal with 1 cup of milk, 1 bagel with 1 Tbsp cream cheese and 1 cup of milk?
A)Negligible, 0
B)Less than 1%
C)Closer to 2%
D)Unable to calculate; the FDA has not set a DV for trans fat

Accepted Answer

The FDA has not established a Daily Value (DV) for trans fats, making it impossible to calculate the percentage of DV from trans fatty acids in any meal based on the information provided.

Question 17

Given that the Daily Value for fat is 65 g, what percentage of the DV for total fat is obtained if 1 serving of Sunny cereal is consumed with 1 serving of milk?
A)2
B)5
C)7
D)9

Accepted Answer

The answer of Given that the Daily Value for fat...

Question 18

Food Labels for Milk, Sunny Start Cereal, Oscar's Bagels, and Auntie Em's Cream Cheese (left to right)
 
-How many total kcalories from fat are provided in the following meal: 1 serving of Sunny Start cereal with 1 cup of milk, 1 bagel with 1 Tbsp cream cheese, and 1 cup of milk?
A)90
B)135
C)144
D)162

Accepted Answer

Total kcalories from fat in the meal= (2g fat per serving of cereal x 1 serving) + (5g fat per bagel x 1 bagel) + (5g fat per Tbsp of cream cheese x 1 Tbsp) + (5g fat per cup of milk x 2 cups) 
= 2 + 5 + 5 + 10 = 22
Therefore, total kcalories from fat in the meal = 22 x 9 = 198
Now, kcalories from fat in 1 g of fat = 9
Therefore, kcalories from fat in 22 g of fat = 198 kcal
The best choice(s) are those that provide the most nutrients with the least amount of kcalories from fat. 
1. Choose whole grain bagels over plain bagels. Whole grain bagels are higher in fiber and nutrients than plain bagels. 
2. Choose low-fat or fat-free milk over whole milk. Low-fat or fat-free milk still provide the same amount of calcium, vitamin D, and other nutrients as whole milk, but with less kcalories from fat. 
3. Choose low-fat or fat-free cream cheese over regular cream cheese. Similar to milk, choosing low-fat or fat-free options for cream cheese will provide the same nutrients with fewer kcalories from fat.

Question 19

Cell membranes are composed of a phospholipid bilayer

Accepted Answer

The phospholipid bilayer is the main component of cell membranes, consisting of two layers of phospholipid molecules arranged tail to tail.

Question 20

-How many total grams of fat are provided in the following meal: 1 serving of Sunny Start cereal with 1 cup of milk, 1 bagel with 1 Tbsp cream cheese, and 1 cup of milk?
A)10
B)15
C)16
D)18

Accepted Answer

The total grams of fat in the meal can be calculated by adding the fat content of each component. Typically, a serving of cereal with milk might contain around 3 grams of fat, a bagel with 1 tablespoon of cream cheese could have approximately 9 grams of fat, and an additional cup of milk could add about 4 grams of fat, totaling 16 grams of fat.
