Beta carotene is a type of natural pigment found in many fruits and vegetables. It gives them their bright orange, red, and yellow colors. The body converts beta carotene into vitamin A, which is essential for good vision, skin health, and a strong immune system.
It is one of the most important antioxidants that help protect the body from harmful free radicals and supports overall health.
What is Beta Carotene?
Beta carotene is a carotenoid, which is a group of plant pigments responsible for bright colors in fruits and vegetables. It acts as a provitamin A, meaning that the body can change it into vitamin A when needed.
Vitamin A plays a vital role in:
- Keeping eyes healthy
- Supporting immune function
- Maintaining healthy skin and mucous membranes
- Helping normal growth and development
Natural Sources of Beta Carotene
Beta carotene is mainly found in colorful fruits and vegetables. Some of the best food sources include:
Vegetables
- Carrots
- Sweet potatoes
- Pumpkin
- Spinach
- Kale
- Broccoli
Fruits
- Mangoes
- Papayas
- Apricots
- Cantaloupe (muskmelon)
- Red and yellow peppers
Cooking some of these vegetables (like carrots or spinach) with a little oil can help your body absorb beta carotene better, since it is fat-soluble.
Functions of Beta Carotene in the Body
Beta carotene has many important roles, such as:
- Converts to Vitamin A – Helps maintain vision, skin, and immune health.
- Antioxidant Function – Protects body cells from damage caused by free radicals.
- Supports Skin Health – Keeps the skin smooth and may help protect against sun damage.
