Question 1

Which dietary pattern is associated with reduced risk of cardiovascular disease and emphasizes olive oil, fish, legumes, and vegetables?

Accepted Answer

Mediterranean diet

Answer

The Mediterranean diet is extensively studied and linked to lower cardiovascular mortality due to its emphasis on monounsaturated fats, fiber, and anti-inflammatory foods.

Question 2

What is the function of bile in fat digestion?

Accepted Answer

It emulsifies fat into small droplets to increase surface area for lipase

Answer

Bile salts emulsify dietary fats into micelles, dramatically increasing the surface area available for pancreatic lipase to digest triglycerides.

Question 3

Advanced glycation end products (AGEs) are formed when:

Accepted Answer

Sugars react with proteins or fats during high-heat cooking

Answer

AGEs form through the Maillard reaction when reducing sugars bond non-enzymatically to proteins or fats under high heat, contributing to oxidative stress and inflammation.

Question 4

Which amino acid is considered conditionally essential and is the most abundant amino acid in muscle tissue?

Accepted Answer

Glutamine

Answer

Glutamine is conditionally essential during stress, illness, or intense exercise, and serves as primary fuel for enterocytes and immune cells.

Question 5

According to IIN's 'crowding out' principle, the best strategy to improve diet quality is to:
