Correct Answer: B

Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.

Correct Answer: B

Rationale: Excessive intake of dietary protein can lead to impaired kidney function over time. Excessive protein consumption can put a strain on the kidneys as they work to eliminate the byproducts of protein metabolism. This can potentially lead to kidney damage. Choices A, C, and D are incorrect. Excessive protein intake is not directly linked to causing vitamin deficiencies, increasing weight loss, or decreasing the production of indispensable amino acids.

Correct Answer: A

Rationale: The correct answer is A: act as buffers. Amino acids can act as buffers by helping to maintain the pH balance in the body. Choice B is incorrect because amino acids do not primarily facilitate glucose storage. Choice C is incorrect as amino acids do not regulate the heartbeat. Choice D is also incorrect because amino acids do not control the level of blood cholesterol.

Correct Answer: C

Rationale: Sucrose is the correct answer as it is the most common disaccharide found in the diet, commonly known as table sugar. Lactose is a disaccharide found in dairy products, not as prevalent in the overall diet as sucrose. Fructose is a monosaccharide commonly found in fruits and honey, not a disaccharide. Galactose is a monosaccharide commonly found in dairy products and is not the most prevalent dietary disaccharide.

Correct Answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.
