The food name of vitamin A

#Preformed Vitamin A#

Vitamin A is an essential fat-soluble vitamin. It is important for good vision, immune function and proper cell growth. Vitamin A is found in many forms, including preformed vitamin (retinol), and provitamin-A carotenoids. Vitamin A and its food sources play a significant role in the health of humans.

**1. Liver:**
Liver, especially in the form retinol, is a rich source of vitamin A preformed. Beef and chicken livers are particularly potent. One serving of beef liver, for example, can contain several times the daily recommended allowance (RDA). The high concentration of Vitamin A in liver makes it a great food for anyone who needs to increase their intake.
**2. Dairy products:
Dairy products like milk, yogurt, cheese and cheese are good sources of vitamin A preformed. Full-fat and whole milk dairy products contain higher levels of Vitamin A than their low-fat counterparts. Plant-based alternatives to milk can provide additional vitamin A for those who follow a plant-based diet.
**3. Eggs:**
The yolks of eggs, in particular, are a good source for preformed vitamin A. Although the vitamin A in eggs is not as high as that found in liver or dairy products, it contributes to your overall intake.


#Provitamin A Carotenoids#
                                                                               

Plant pigments called provitamin A carotenoids can be converted by the body into retinol. They include beta-carotene and alpha-carotene. Carotenoids in foods can increase vitamin A levels by converting them into active forms.

**1. Carrots:**
Carrots contain beta-carotene which is a provitamin A carotenoid. It is widely known that carrots promote good vision and regular consumption can help to maintain adequate vitamin levels.
**2. Sweet Potatoes:**
One serving of sweet potatoes can supply a large portion of your daily vitamin A requirement. The versatile vegetables can be used in many different dishes from soups to casseroles.
**3. Dark Leafy Greens**
Leafy greens like spinach, Swiss chard, and kale are high in beta-carotene. These vegetables not only provide vitamin A but also additional nutrients such as iron and fiber.
**4. **Red and orange Fruits
Mangoes, cantaloupes, and apricots are rich in provitamin A. These fruits are delicious and contribute to a varied diet that is rich in vitamin A.
**5. Pumpkins:**
Beta-carotene is abundant in pumpkins and other orange vegetables, such as butternut squash. Pumpkins are used in soups and pies as well as a wide variety of other dishes.
Fortification is a common way to add vitamin A to foods, in addition to the natural sources. It is common to find this in cereals and margarine. Fortified foods are a good source of vitamin A for people who have limited access to other nutrients-rich foods.


#Vitamin A: Its importance#

Vitamin A has many important roles to play in the body.

**1. Vision:**
Vitamin A is essential for good vision. Vitamin A is an essential component of the pigment rhodopsin in the retina, which allows low-light vision and color vision. Vitamin A deficiency can cause night blindness, as well as other visual impairments.
**2. Immune Function:**
Vitamin A helps to support the immune system, by maintaining the integrity and function of skin and mucous tissues that act as barriers against pathogens. Vitamin A is also essential in the production of white blood cell, which is vital for fighting infection.
**3. Cellular Growth and Differentiation :
Vitamin A plays a role in cell growth and differentiation. It is important for embryonic development, and it helps maintain healthy skin and epithelial tissue.


#Conclusion#

Vitamin A plays a vital role in the health of cells, vision and immune function. Both animal and plant-based sources are available. Liver, dairy products and eggs provide preformed vitamin A while vegetables and fruits contain provitamin A. You can ensure that you are getting enough vitamin A by including a variety in your diet.
