If an adult consumes a very low-fat diet that supplies only 5% of energy as fat, which of the following is the most likely immediate nutritional consequence related to fat-soluble vitamins?

• A. Improved absorption of fat-soluble vitamins because lower fat intake upregulates micelle formation enhancing uptake of these vitamins.
• B. Reduced efficiency of absorption of vitamins A, D, E, and K in the gut, increasing risk of deficiencies over time if fat intake remains very low.
• C. No effect on fat-soluble vitamin status because these vitamins are water-soluble and independent of dietary fat for absorption.
• D. Immediate loss of stored fat-soluble vitamins once dietary fat drops below 10% since the body cannot mobilize adipose stores to maintain vitamin status.

Answer: (B)
