Vitamin A is an essential fat-soluble vitamin that has many important functions in the human body. There are two major forms of vitamin A; Preformed vitamin A, which includes retinol and retinyl esters, and Provitamin A, which includes alpha-carotene & beta-carotene. Preformed vitamin A is found in animal food products, whereas provitamin A carotenoids are found in plant food sources and are converted into retinol within the human body. Vitamin A and its metabolites are essentially required for vision, cellular differentiation, immune function, and epithelial barrier function. So, in this video we are going to look at the richest food sources of vitamin A.

Vitamin A is an essential fat-soluble vitamin that has many important functions in the human body.
There are two major forms of vitamin A.
Preformed vitamin A, which includes retinol and retinol esters,
and provitamin A, which includes alpha-carotene and beta-carotene.
Preformed vitamin A is found in animal food products,
whereas provitamin acarotenoids are found in plant food sources
and are converted into retinol within the human body.
Vitamin A and its metabolites are essentially required for vision,
cellular differentiation, immune function, and epithelial barrier function.
So in this video, we are going to look at the richest food sources of vitamin A.
Animal Liver
Animal liver is probably the most well-known food source of vitamin A.
Liver provides massive amounts of vitamin A.
For example, a 100-gram serving of cooked beef contains more than 8 times the daily requirement of vitamin A.
Saying that, it is best to take animal liver in moderation since regular consumption is not good for your health.
Dairy Products
Dairy products such as milk and cheese are good sources of vitamin A.
They are also rich in quality proteins and other essential minerals such as calcium, phosphorus, and potassium.
Cod Liver Oil
Cod liver oil is another great source of vitamin A.
Just one tablespoon of cod liver oil will provide four times the required daily intake of vitamin A.
It is also a rich source of vitamin D.
Studies indicate that cod liver oil has beneficial effects on blood cholesterol levels,
especially when taken with a statin like rosovastatin.
Fatty Fish
Fatty fish like salmon, tuna, and mackerel are also good sources of vitamin A,
although the amounts may vary depending on the type of the fish.
They also provide good amounts of proteins, healthy fats, and other essential vitamins and minerals.
Fatty fish would be a wise addition to your diet since they improve your overall health in many aspects.
Studies indicate that regular intake of fatty fish is associated with a reduced risk of chronic illnesses such as diabetes and heart disease.
Eggs
If you are looking for a cheaper food source to get almost all the nutrients in one go, eggs would be an excellent option.
Eggs are packed with essential vitamins and minerals, and they are a great source of quality protein.
They also provide healthy fats and choline, an important nutrient for good health.
Carrots
Carrots are probably the well-known plant food source of vitamin A.
Just one cup of carrots contains about 140% of the recommended daily value for vitamin A.
Carrots are also a good source of plant-based antioxidants and fiber.
