Question 1

If vitamin C has been added to cranberry juice, the label must include:

Accepted Answer

Adding vitamin C to cranberry juice is a nutrient modification, therefore, nutrient information must be included on the label. An ingredients list is also required to indicate that vitamin C has been added to the juice. Therefore, options A and B are correct. A health claim is not necessarily required for adding vitamin C to cranberry juice, therefore, option C is not correct.

Question 2

Question 3

Which of the following have the scientists who have been doing research on phytochemicals in foods found to be true?

Accepted Answer

Research on phytochemicals in foods has shown possible health benefits in cell and animal studies. While some phytochemicals have been recognized for their roles in taste and color of foods, their health benefits in people were not recognized until more recent research. There are many different compounds found in foods that can be considered phytochemicals, and consuming them in the form of a whole food is generally more effective than taking them as a supplement.

Question 4

If you were teaching someone with diabetes how to plan a diet to control carbohydrate intakes, which of the following tools would you use?

Accepted Answer

The exchange list system provides a helpful tool for individuals with diabetes to plan their meals, as it groups foods based on their carbohydrate, protein, and fat content. This allows for more precise control over carbohydrate intake, which is important for managing blood sugar levels. The other options may provide helpful guidelines for overall healthy eating, but may not be as specific to the needs of individuals with diabetes.

Question 5

You are planning a meal that includes a hamburger on a bun, coleslaw, and French fries. To have a more nutrient-dense meal, you should eat:

Accepted Answer

Pork tenderloin is a leaner protein source than fried chicken or spare ribs, and green peas offer fiber and vitamins. Brown rice is a healthier carbohydrate option than French fries, and strawberries provide a serving of fruit. Overall, this option offers a more nutrient-dense meal.

Question 6

Which of the following includes the recommended daily amounts of food from each group for a sedentary woman of 32 who requires 1,800 kcal/day, based on the USDA Food Patterns?

Question 7

Tea and certain spices are not included in the USDA Food Patterns. This means that you should consider which of the following when deciding whether to include them in your diet?

Question 8

Blueberries have been leading the way in research on the effectiveness of antioxidants against aging effects on the brain. What would be your comments about eating more blueberries in your diet?

Accepted Answer

Recent studies have primarily been conducted on laboratory animals, and the direct benefits for humans are not yet fully established.

Question 9

Question 10

You are speaking to a group of consumers about ways to use food labels to choose healthy foods in the grocery store. During your presentation, what would you emphasize?

Accepted Answer

It is important to compare similar food products based on nutrient components, such as calories, fat, sugar, and sodium. Understanding the descriptive terms on food labels, such as "low-fat" or "organic," can also help consumers make informed choices. The grams and numbers on the labels can be helpful for calculating percentages, but they may be less important for the average consumer.

Question 11

When determining the amounts of foods from each group to eat using the USDA Food Patterns, you need to remember that:

Accepted Answer

The recommended amounts of foods from each group will vary depending on factors such as age, physical activity, and gender. Therefore, it is important to consider individual needs and make adjustments accordingly.

Question 12

A woman who has begun a new exercise program to keep herself healthy will need to consider that her discretionary calorie allowance:

Accepted Answer

When starting a new exercise program and increasing activity level, the discretionary calorie allowance can increase. Discretionary calories are the remaining calories after accounting for all the essential nutrients an individual needs. As long as the person continues to eat a balanced diet and does not exceed their total calorie needs, they can allocate some of those extra calories towards discretionary items such as sweets, alcohol, or other indulgences. However, it's important to note that the increase in discretionary calories should not be significant and should be balanced with a healthy diet and portion control.

Question 13

A 51-year-old sedentary woman still has some discretionary calories available for her evening meal. Her most nutritious choice for that meal would be to:

Accepted Answer

The most nutritious choice would be to have a serving of cooked carrots with her meal in addition to her salad as this would add valuable nutrients and fiber without adding excessive calories. Options A and B are high in calories, saturated fat, and added sugars, while option C adds unhealthy trans fats.

Question 14

An important role of the exchange system of categorizing foods is to:

Accepted Answer

The exchange system categorizes foods into groups based on their macronutrient content, allowing individuals to make informed choices about their food intake. These groupings are based on similar carbohydrate, fat, protein, and calorie contents, making it easier for individuals to plan their meals based on their nutritional needs. The other options are not accurate descriptions of the purpose of the exchange system.

Question 15

If a food label states that a food contains eight percent of the Daily Value for dietary fiber, the food would contain _____ grams of dietary fiber per serving.

Accepted Answer

To calculate the grams of dietary fiber per serving, we need to know the Daily Value amount for fiber, which is 25 grams. 8% of 25 grams is 2 grams (0.08 x 25 = 2), so the food would contain two grams of dietary fiber per serving. Therefore, the best choice is B.

Question 16

The Nutrition Facts panel on a food label lists the following information for amounts per serving: 111 calories; 23 calories from fat. What percentage of the calories are provided by fat?

Accepted Answer

The answer of The Nutrition Facts panel on a food...

Question 17

When you see that foods have a high nutrient density, you should:

Accepted Answer

Choosing foods with high nutrient density is important for a healthy diet, and they form the foundation of the USDA Food Patterns. They provide essential nutrients while not necessarily being high in calories, making them good choices for weight management. Avoiding them or using them sparingly would not be the best choice.

Question 18

Which of the following lunches best fits into a meal plan suggesting that a person eat 1 cup vegetables, 2 ounces grains, and 2 ounces protein foods at lunch?

Accepted Answer

Stir-fry of 1/2 cup tofu and 1 cup mixed vegetables on 1 cup cooked rice fits the meal plan best as it contains 1 cup of vegetables, 2 ounces of grains (from 1 cup cooked rice), and 2 ounces of protein (from 1/2 cup tofu). The other options do not contain the recommended amounts for each food group. Option A only has 1 cup of vegetables, Option B only has 2 ounces of protein, and Option D only has 2 ounces of grains.

Question 19

Recent research on the health benefits of flavonoids found in dark chocolate has shown all of the following except:

Accepted Answer

While some studies have suggested that chocolate consumption may have a protective effect against heart disease, the evidence is still not definitive and more research is needed to confirm this potential benefit.

Question 20

A food manufacturer has included the following claim on the container label for a product: "Helps maintain normal iron levels." If you were evaluating the claim, you would:

Accepted Answer

Structure-function claims do not require pre-approval from the FDA, making them more susceptible to exaggerated or misleading statements. Therefore, it is important to approach them with skepticism and gather more information before accepting the claim as accurate.
