Vitamin A is
A is very important for maintaining good vision. In fact,
the first sign of a vitamin A deficiency is often night
blindness. Vitamin A also contributes to the maintenance of
healthy skin and mucous membranes that line the nose,
sinuses, and mouth. Research has shown that this nutrient is
necessary for proper immune system function, growth, bone
formation, reproduction, and wound healing.
Vitamin A, in the form of retinyl palmitate, is found in
beef, calf, chicken liver; eggs, and fish liver oils as well
as dairy products including whole milk, whole milk yogurt,
whole milk cottage cheese, butter, and cheese.
Vitamin A can also be produced in the body from
beta-carotene and other carotenoids (fat-soluble nutrients
found in fruits and vegetables).
Most dark-green leafy vegetables and deep yellow/orange
vegetables and fruits (sweet potatoes, carrots, pumpkin and
other winter squashes, cantaloupe, apricots, peaches, and
mangoes) contain substantial amounts of beta-carotene. By
eating these beta-carotene rich foods, a person can increase
their supply of vitamin A.
