Fat soluble Vitamins Flashcards
Q: What are the fat-soluble vitamins?
The fat-soluble vitamins are vitamins A, D, E, and K.
Why are fat-soluble vitamins called ‘fat-soluble’?
They dissolve in fats and oils, not in water, and are stored in the body’s fatty tissues and liver.
What are the main food sources of Vitamin A?
Liver, fish oils, dairy products, leafy green vegetables, and orange/yellow fruits like carrots and sweet potatoes.
What is the main function of Vitamin A in the body?
Vitamin A is essential for good vision, immune function, reproduction, and cell growth.
What deficiency disease is associated with Vitamin A deficiency?
Night blindness and, in severe cases, xerophthalmia, which can lead to blindness.
What are the main food sources of Vitamin D?
Oily fish, egg yolks, fortified dairy products, and exposure to sunlight.
What is the primary function of Vitamin D?
Vitamin D helps with calcium and phosphorus absorption, essential for healthy bones and teeth.
What disease is caused by Vitamin D deficiency in children and adults?
Rickets in children and osteomalacia in adults, both causing soft, weak bones.
What are some good dietary sources of Vitamin E?
Nuts, seeds, vegetable oils, and green leafy vegetables.
What is the main function of Vitamin E?
Vitamin E acts as an antioxidant, protecting cells from damage, and supports immune health.
What deficiency symptoms might occur due to low Vitamin E?
Muscle weakness, nerve damage, and, in severe cases, vision and immune issues.
What are the main dietary sources of Vitamin K?
Green leafy vegetables, fish, meat, and eggs.
What is the primary role of Vitamin K in the body?
Vitamin K is essential for blood clotting and bone health.
What deficiency condition is linked to Vitamin K deficiency?
Increased bleeding and bruising due to poor blood clotting.
Can the body store fat-soluble vitamins, and why is this important?
Yes, they can be stored in the liver and fatty tissues, which helps prevent immediate deficiency but can lead to toxicity if overconsumed.
