Which nutrient aids in the absorption of fat-soluble vitamins?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Minerals

Answer: (C)

Fat is the medium that allows fat-soluble vitamins to be absorbed. When you consume fat, bile salts emulsify it and pancreatic enzymes break it down into fatty acids and monoglycerides. The fat-soluble vitamins dissolve into these fat-containing micelles, which ferry them to the enterocytes of the small intestine. Inside the cells, fats and vitamins are reassembled into triglycerides and packaged into chylomicrons that enter the lymphatic system and eventually reach the bloodstream. Without adequate dietary fat, absorption of vitamins A, D, E, and K is reduced, increasing the risk of deficiencies. Carbohydrates, proteins, and minerals don’t play this specific role in enabling fat-soluble vitamin absorption.
