Question 2

A client with hypothyroidism asks about dietary goitrogens. Which food group is highest in naturally occurring goitrogens?

Accepted Answer

Cruciferous vegetables like broccoli and kale

Answer

Cruciferous vegetables contain glucosinolates that can interfere with thyroid iodine uptake, though cooking significantly reduces their goitrogenic activity.

Question 3

The glycemic index (GI) of a food is primarily affected by which factor?

Accepted Answer

The speed at which carbohydrates are digested and raise blood glucose

Answer

GI measures how quickly a carbohydrate-containing food raises blood glucose compared to pure glucose, reflecting digestion and absorption speed.

Question 4

Which nutrient deficiency is most commonly associated with increased risk of colorectal cancer according to current evidence?

Accepted Answer

Vitamin D

Answer

Low vitamin D status is associated with increased colorectal cancer risk due to its role in regulating cell proliferation and apoptosis in the colon.

Question 5

In the context of chronic disease, what is 'leaky gut' (intestinal permeability) primarily thought to contribute to?

Accepted Answer

Systemic inflammation via translocation of bacterial endotoxins

Answer

Increased intestinal permeability allows bacterial lipopolysaccharides (LPS) to enter the bloodstream, triggering chronic systemic inflammation linked to metabolic and autoimmune diseases.
