Question 1 of 5
Low levels of high-density lipoproteins (HDL) are?
Correct Answer: C
Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.
Question 2 of 5
In the following ingredient list, which is the most abundant by weight? Ingredients: enriched flour, sugars, eggs, soy lecithin, artificial colors, natural flavors, milk.
Correct Answer: D
Rationale: The correct answer is 'enriched flour.' In ingredient lists, items are typically listed by weight in descending order. Therefore, the first ingredient, in this case, 'enriched flour,' is the most abundant by weight. Choice A, 'milk,' is not the most abundant as it appears last in the list. Choice B, 'eggs,' and choice C, 'sugar,' also rank lower in the list compared to 'enriched flour,' making them less abundant by weight.
Question 3 of 5
A dietitian tells you that you are not consuming enough calories. Which of the following nutrients could you add to your diet to increase your energy intake?
Correct Answer: C
Rationale: Corrected Rationale: Protein provides 4 kcal per gram, making it a good source of energy to increase caloric intake. While fiber and water are important for other aspects of health, they do not provide energy like protein does. Vitamins are essential for various bodily functions but do not contribute directly to caloric intake.
Question 4 of 5
Which of the following suggestions is the healthiest for Miguel, who is always hungry and never seems to feel full despite eating enough calories?
Correct Answer: C
Rationale: The correct answer is A and B. Switching to more nutrient-dense foods can help Miguel feel full despite eating enough calories. Nutrient-dense foods provide essential nutrients and are more satisfying. Drinking adequate water is also crucial for overall health and can help with feelings of fullness. Choice D is incorrect because while fat can contribute to satiety, it should be consumed in balance with other nutrients. Consuming foods with high fat content excessively may lead to other health issues and does not address the underlying problem of feeling constantly hungry despite eating.
