Research says beta carotene can reduce the rate of dementia in men
Release date: 2007-12-03 A recent study suggests that long-term use of beta carotene may help reduce the risk of dementia in men. The research, conducted by Brigham and Women's Hospital and Harvard Medical School, found that men who regularly took beta carotene had better cognitive performance compared to those who took a placebo. According to reports from Singapore's Lianhe Zaobao, beta carotene is an antioxidant commonly found in vegetables like radishes. Once consumed, the liver converts it into vitamin A, which helps protect the body against free radical damage.
The study involved 4,052 male participants who were given either a placebo or 50 mg of beta carotene every other day starting in 1982. Over time, they underwent various cognitive tests, with researchers noting that changes in hearing ability were among the best indicators of potential dementia development. Those who took beta carotene consistently showed better results on these assessments. Based on their findings, the research team concluded that long-term beta carotene use could have meaningful health benefits.
However, the study also highlighted some risks associated with beta carotene. Notably, it was found to increase the risk of lung cancer in smokers. This underscores the importance of considering individual health conditions before starting any supplement regimen. While the results are promising, further research is needed to fully understand the long-term effects of beta carotene on brain health.
