What foods contain Vitamin A?
Vitamin A comes from animal sources, such as eggs, meat, fortified milk, cheese, cream, liver, kidney, cod, and halibut fish oil. However, all of these sources — except for skim milk that has been fortified with this vitamin — are high in saturated fat and cholesterol.
Other foods with it include beta-carotene and the following:
Bright yellow and orange fruits such as cantaloupe, pink grapefruit, and apricots
Vegetables such as carrots, pumpkin, sweet potatoes, and winter squash
Other sources of beta-carotene include broccoli, spinach, and most dark green, leafy vegetables.
