1. It has been generally accepted that the percentage of total daily calories supplied by fats should be no more than:

Correct answer: C

Rationale: The recommended fat intake is between 20% to 35% of total daily calories. This range is considered optimal for maintaining a healthy diet. Choice A (10% to 15%) is too low and might not provide enough essential fats for the body. Choice B (10% to 35%) includes an upper limit that exceeds the generally accepted range. Choice D (40% to 55%) suggests a fat intake that is higher than what is recommended, which could lead to health issues if consumed regularly.

2. Carbohydrates are composed of a combination of carbon, hydrogen, and which other element?

Correct answer: A

Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.

3. A high blood cholesterol level appears to be associated with the development of:

Correct answer: B

Rationale: A high blood cholesterol level is associated with an increased risk of developing coronary heart disease. Elevated cholesterol levels can lead to the buildup of plaque in the arteries, increasing the risk of heart disease. Choices A, C, and D are incorrect as high blood cholesterol is not primarily linked to chronic kidney disease, Alzheimer’s disease, or Addison’s disease.

4. Where are sugar alcohols most likely to be found?

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.

5. What group makes each amino acid unique?

Correct answer: A

Rationale: The correct answer is the radical group (R-group) because it is the unique side chain that differentiates each amino acid. The amino group (choice B) and carboxyl group (choice C) are functional groups common to all amino acids but do not make them unique. The peptide bond (choice D) is the bond formed between amino acids in a protein chain, not the group that makes each amino acid unique.
