Carotenoids
Carotenoids are pigments found in plants, responsible for their vibrant colors, and serve as antioxidants in the human body, protecting cells from damage and promoting overall health.
Effectiveness and Risk Overview
Condition | Effectiveness | Details |
|---|---|---|
| Oxidative Stress | Carotenoids are potent antioxidants that neutralize free radicals, thereby reducing oxidative stress. This effect is well-documented in various in vitro, in vivo, and clinical studies. | |
| Antioxidant Activity | Carotenoids are known for their strong antioxidant properties, which help in neutralizing free radicals and reducing oxidative damage. This is supported by a large body of in vitro and in vivo evidence. | |
| Eye Health | Carotenoids, especially lutein and zeaxanthin, are known to protect eye health and reduce the risk of age-related eye diseases. This is supported by clinical studies and meta-analyses. | |
| Skin Aging | Carotenoids have been found to protect the skin from sun damage and improve skin health, reducing signs of aging. Evidence comes from both observational studies and clinical trials. | |
| Cognitive Longevity | Some carotenoids may support cognitive health and potentially reduce the risk of cognitive decline. While the evidence is promising, it is largely based on observational studies and more research is needed. | |
| Increases lung cancer risk. | High doses of beta-carotene, a type of carotenoid, have been linked to an increased risk of lung cancer in smokers, as it may promote the growth of cancer cells in the lungs, although this risk is not associated with a diet rich in carotenoids. |
