Carotenoids are important for human health because they act as powerful antioxidants, protect against certain cancers and heart disease, and support vision and immune function. Some, like beta-carotene, are converted to vitamin A, which is crucial for vision, cell growth, and immune response. Others, like lutein and zeaxanthin, protect eye health, particularly against age-related macular degeneration and cataracts.
Key benefits of carotenoids
Antioxidant properties: Carotenoids neutralize harmful free radicals, which helps protect cells from damage and lowers the risk of chronic diseases.
Eye health:
Lutein and zeaxanthin: These carotenoids are concentrated in the retina and help protect against blue light damage and slow the progression of age-related macular degeneration and cataracts.
Beta-carotene: Serves as a precursor to vitamin A, which is essential for good vision.
Cancer prevention:
Studies suggest a link between high carotenoid intake and a reduced risk of certain cancers, particularly prostate cancer (lycopene).
They may also offer protection against other cancers like lung, breast, and gastrointestinal cancers.
Cardiovascular health:
Carotenoids like lycopene have been shown to reduce cholesterol levels and protect LDL ("bad") cholesterol from oxidation, which is a risk factor for heart disease.
They may also help with blood sugar stability and reduce inflammation.
Immune support:
Beta-carotene conversion to vitamin A is vital for a healthy immune system.
Some carotenoids can enhance immune function and reduce inflammation throughout the body.
