Q.55
For adequate absorption of Vitamin A, E, D and K we must include adequate amount of
which of the following nutrient in our
diet?
- Dietary Lipid Requirement for Fat-Soluble Vitamin Absorption:
- Fat-Soluble Vitamins (A, D, E, K):
- Non-polar, lipophilic micronutrients that cannot dissolve directly in aqueous gastrointestinal fluids.
- Absorption Physiology:
- Dietary fats (triglycerides) stimulate gallbladder contraction, releasing bile salts into the duodenum.
- Bile salts, monoglycerides, and fatty acids spontaneously aggregate into mixed micelles, encapsulating vitamins A, D, E, and K to transport them across the intestinal unstirred water layer into enterocytes for packaging into chylomicrons.
- Conclusion: Fats (Option 3).
Correct option: (3) Fats
