Foods High in Vitamin A: Key Sources and Dietary Patterns
Plant-Based Foods Rich in Vitamin A (Provitamin A Carotenoids)
Many vegetables and fruits are excellent sources of provitamin A carotenoids, which the body converts into active vitamin A. Notably, spinach, carrots, pumpkin, sweet potatoes, kale, cabbage, squash, broccoli, and other dark green or yellow-orange vegetables are high in these nutrients. Studies show that spinach and carrots can provide significant amounts of vitamin A, although the bioavailability and conversion efficiency can vary depending on the food matrix and preparation methods15. Pumpkin, in particular, is highlighted as a potent source, with less than 50 grams of cooked pumpkin per day meeting the full recommended intake for young children. Orange-fleshed sweet potatoes are also rich in beta-carotene and can supply more than half of the vitamin A needs for infants when included in complementary foods.
Animal-Based Foods High in Preformed Vitamin A (Retinol)
Animal-derived foods provide preformed vitamin A, which is more readily absorbed by the body. Key sources include liver, egg yolk, whole milk, butter, and fish oil58. Liver is especially rich in vitamin A, and even small amounts can significantly boost vitamin A status. Eggs and dairy products also contribute to daily intake, though in smaller amounts compared to liver258.
Contribution of Different Food Types to Vitamin A Intake
Vegetables are the largest contributors to vitamin A intake in many diets, accounting for over half of the daily intake in some populations, followed by eggs, milk, aquatic products, meat, fruit, legumes, and cereals. Dietary patterns that include a variety of vitamin A-rich foods—especially dark leafy greens, yellow/orange fruits, and animal sources like liver—are associated with improved vitamin A status, as measured by biomarkers such as retinol binding protein.
Fortified Foods and Food-Based Strategies
In regions where vitamin A deficiency is common, fortification of staple foods (such as oils, flours, and dairy products) with vitamin A is used to help meet dietary needs. While the impact of fortification alone on vitamin A status can be variable, combining vitamin A with other micronutrients in fortified foods may help reduce the risk of deficiency. Food-based strategies, including dietary diversification and nutrition education, are considered sustainable and effective approaches to combat vitamin A deficiency.
Conclusion
Foods high in vitamin A include both plant-based sources rich in provitamin A carotenoids (such as spinach, carrots, pumpkin, sweet potatoes, and dark leafy greens) and animal-based sources of preformed vitamin A (such as liver, egg yolk, whole milk, and fish oil). Including a variety of these foods in the diet, along with fortified staples where needed, is key to meeting daily vitamin A requirements and supporting overall health1234+4 MORE.
