What is the most significant dietary influence on the development of dental caries?

  • A. Carbohydrates
  • B. Vitamins
  • C. Minerals
  • D. Fats
Correct Answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

Does the hypothalamus control the feeling of hunger and satiety, and are fats the best nutrient in creating the feeling of satiety?

  • A. TRUE
  • B. FALSE
Correct Answer: A

Rationale: Yes, the hypothalamus plays a crucial role in regulating hunger and satiety. Fats are indeed known to be highly satiating nutrients, helping to create a feeling of fullness and satisfaction after a meal. Therefore, both statements are true. Choice B is incorrect because fats are indeed effective in promoting satiety.

Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

  • A. The DRIs replace the older recommended daily allowances
  • B. Current DRIs attempt to estimate required nutrients to improve long-term health
  • C. DRIs specifically address individuals whose requirements are affected by a disease state
  • D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients
Correct Answer: C

Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

Match amylase with its digestive action:

  • A. breaks down carbs
  • B. breaks down proteins
  • C. breaks down lipids
  • D. helps fat digestion
Correct Answer: A

Rationale: The correct answer is A: 'breaks down carbs.' Amylase is an enzyme that specifically targets carbohydrates, breaking them down into simpler sugars like maltose. This process aids in the digestion of carbohydrates in the human body. Choices B, C, and D are incorrect because amylase does not break down proteins, lipids, or directly aid fat digestion. Proteins are broken down by proteases, lipids are broken down by lipases, and fat digestion is primarily assisted by bile salts and lipases in the small intestine.

Almost all (99%) of the calcium in the body is used for?

  • A. regulating the transmission of nerve impulses
  • B. providing energy for cells
  • C. providing rigidity for the bones
  • D. regulating muscle contraction
Correct Answer: C

Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.
