How Vitamin-A Useful to our Body

The Vitamin A that we get in our diet is a fat-soluble, fat-sourced, fat-sensing nutrient. The body uses Vitamin A for growth, cell metabolism, and for the building and maintenance of the immune system. Vitamin A has a myriad of health benefits and is also essential to a healthy skin.

In fact, there are two categories of vitamin A; the one from animal-based foods is referred to as retinol (Vitamin A). This “pre-formed” form can be easily absorbed by the body; however, when it is converted to retinaldehyde, this substance is broken down by enzymes.

As retinaldehyde breaks down, it will produce the “vitamin A” that we refer to as retinal. In most cases, this is absorbed into the blood stream by way of a blood vessel known as the blood thin.

Retinol is not easily eliminated through the kidneys or liver, and it is not metabolized properly to produce the other benefits of vitamin A. In fact, it is not even converted to retinal (that is, it does not enter the bloodstream) until it is broken down and then, only at a very slow rate.

The second category of vitamin A is referred to as beta-carotene (Vitamin A) because of its ability to increase the body’s metabolism. Because beta-carotene cannot enter the bloodstream, it is not broken down in the body to provide the health benefits of vitamin A.

Beta-carotene is also broken down to a very small amount, and when this small amount is absorbed into the bloodstream, it enters the bloodstream at a very rapid rate, providing most of the health benefits of vitamin A.

The best fruit sources of vitamin a is oranges and lemons. These fruits contain the highest concentration of vitamin a because they are rich in beta-carotene. Although citrus fruits can be eaten in moderation, they should be eaten in their natural raw form.

Many fruits also contain vitamin D, another important vitamin, but the concentration of this vitamin in these fruits is very low. It is advisable to consume more than enough vitamin D through the daily diet.

Other than being an important part of a healthy diet, vitamin a also has several other benefits that have been shown to improve health. The best fruits that offer the best benefits of vitamin a include apricots, carrots, figs, grapefruit, papaya, pineapple, and oranges. Because each fruit contains a different amount of beta-carotene, and vitamin D, it is important to eat a wide variety of fruits in order to get all the benefits of vitamin a.

For example, it is better to eat as much sunflower seeds as possible during the summer months, and then have as many bananas as you can between May and December.
