Question 1
Which best illustrates the chronological order of the digestion of fat?
Correct Answer:
Pancreatic lipase, emulsification, micelles, blood, lymph
Explanation:
Fat digestion follows a clear sequence in the small intestine. First, bile salts emulsify fats into smaller droplets, increasing surface area. Then pancreatic lipase acts on these emulsified fats to release fatty acids and monoglycerides. The products associate with bile salts to form micelles, which deliver them to the intestinal lining for absorption. Inside the enterocytes, they are reassembled into triglycerides and packed into chylomicrons that enter the lymphatic system before reaching the bloodstream. So the best order is emulsification, pancreatic lipase action, micelle formation, lymphatic transport, then blood. This sequence matters because lipase needs emulsified fat to work, micelles form after lipase action, and transport to blood occurs after lymphatic drainage.
Question 2
Trans fats are associated with which cardiovascular effect and foods containing them?
Correct Answer:
Raise LDL and lower HDL
Explanation:
Trans fats disrupt cholesterol in a way that harms heart health: they raise LDL, the “bad” cholesterol, and lower HDL, the “good” cholesterol. This combination worsens the lipid profile and increases the risk of plaque buildup in arteries, which is a key driver of cardiovascular disease. That makes the described effect—raising LDL and lowering HDL—the best match for how trans fats influence heart health. Trans fats are commonly found in foods made with partially hydrogenated oils, such as some commercially baked goods, fried foods, and certain margarine products. Because of their impact on LDL and HDL, avoiding trans fats is strongly recommended for cardiovascular health.
Question 3
What effect do foods with a high glycemic index have on the body?
Correct Answer:
Increase insulin
Explanation:
Foods with a high glycemic index cause a rapid rise in blood glucose after you eat them. That quick spike signals the pancreas to release more insulin, the hormone that helps glucose move from the bloodstream into cells for energy or storage. So the body responds with an increase in insulin after a high‑GI meal. This contrast with lower‑GI foods, which cause slower, smaller glucose and insulin changes. The rapid insulin rise is why high‑GI foods can lead to sharper fluctuations in blood sugar and insulin levels.
Question 4
Which statement about AI (Adequate Intake) is true?
Correct Answer:
It is used when RDI cannot be determined.
Explanation:
Adequate Intake is a value used when there isn’t enough evidence to establish a precise requirement or to set an RDI/RDA. It represents a level of daily intake that appears to sustain health for a group, based on observed intakes or experimental data, and it serves as a guide when the data are insufficient to determine an EAR/RDA. That’s why this statement—useful when the usual RDI cannot be determined—is the best fit. The other descriptions fit other reference values: the idea of an average daily intake to meet needs is more aligned with how RDAs are defined, planning for athletes uses general dietary guidelines rather than AI, and the notion of a maximum daily intake corresponds to the Upper Intake Level (UL).
Question 5
Which substance has been found to have a great effect on hormones and can affect the functioning of the body?
Correct Answer:
alcohol consumption
Explanation:
Alcohol consumption can strongly affect the hormonal system and how the body functions. When alcohol is processed, it taxes the liver and changes how hormones are metabolized and cleared, which can shift levels of several hormones. It can raise cortisol, alter sex hormones like estrogen and testosterone, and influence thyroid function and insulin signaling. These hormonal shifts can ripple through many body processes, affecting metabolism, mood, sleep, and reproductive health. Other options may influence metabolism or temporary stress responses, but alcohol has the most widespread and pronounced impact on hormones.
