Why are diets that contain less than 10% of kcalories as fat not recommended?

  • A. Intake of carbohydrates would not necessarily be too high.
  • B. This would not necessarily require excessive use of fat replacers.
  • C. The diet would not provide adequate essential fatty acids.
  • D. Intake of essential fatty acids would be too low.
Correct Answer: D

Rationale: Diets that contain less than 10% of kcalories as fat are not recommended because they would lead to inadequate intake of essential fatty acids, which are crucial for various bodily functions like hormone production, brain function, and cell membrane structure. Option A is incorrect because reducing fat intake does not necessarily mean increasing carbohydrate intake excessively. Option B is incorrect as it introduces a new concept of using fat replacers, which is not directly related to the issue of essential fatty acid intake. Option C is incorrect as the primary concern with low-fat diets is the insufficiency of essential fatty acids, not the adequacy of them.

Which mineral helps strengthen tooth enamel and prevent dental caries?

  • A. Calcium
  • B. Phosphorus
  • C. Fluoride
  • D. Zinc
Correct Answer: C

Rationale: The correct answer is C, Fluoride. Fluoride is a mineral known for its ability to strengthen tooth enamel and prevent dental caries. While calcium (Choice A) is essential for strong bones and teeth, it is not specifically known for preventing dental caries. Phosphorus (Choice B) is crucial for bone health but is not directly associated with preventing dental caries. Zinc (Choice D) is not typically recognized for strengthening tooth enamel or preventing dental caries.

How many kilocalories (kcal) are provided by 35 g of fat?

  • A. 140
  • B. 245
  • C. 315
  • D. 360
Correct Answer: C

Rationale: Fat provides 9 kcal per gram, so 35 grams of fat provides 315 kcal. Therefore, the correct answer is C. Choice A (140) is incorrect because it doesn't consider the energy content of fat. Choice B (245) is incorrect as it miscalculates the kilocalories provided by 35g of fat. Choice D (360) is incorrect because it overestimates the kilocalories provided by 35g of fat.

During lactation, where is lactose synthesized in the body?

  • A. Liver
  • B. Breast
  • C. Kidney
  • D. Pancreas
Correct Answer: B

Rationale: The correct answer is B: Breast. Lactose is synthesized in the breast during lactation to produce breastmilk. The liver is responsible for various metabolic functions but does not synthesize lactose. The kidney's primary role is in filtering blood and regulating electrolytes, not lactose synthesis. The pancreas is involved in producing digestive enzymes and insulin, not lactose synthesis.

In which health problem is protein catabolism increased?

  • A. severe burns
  • B. severe obesity
  • C. hypothyroidism
  • D. food allergies
Correct Answer: A

Rationale: Protein catabolism increases in conditions like severe burns because the body breaks down muscle protein to provide energy for healing. Severe obesity does not necessarily increase protein catabolism; instead, it is more related to excessive fat accumulation. Hypothyroidism may lead to a decrease in metabolic rate but does not directly increase protein catabolism. Food allergies trigger an immune response to specific foods but do not directly impact protein catabolism.

Where are sugar alcohols most likely to be found?

  • A. Fermented foods.
  • B. Low-calorie foods.
  • C. Fruits and vegetables.
  • D. Fiber supplements.
Correct Answer: B

Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.
