People with high levels of antioxidants in their blood are less likely to develop dementia later in life, according to a new US study.
The researchers, led by epidemiologist Dr. May Beidoun of the US National Institute on Aging in Baltimore, published in the journal Neurology of the American Academy of Neurology and analyzed data on 7.283 people over the age of 45 at a depth of 16 years. The participants had blood tests to analyze their antioxidant levels, while they were monitored to determine who developed dementia in the course of the research.
Where are the first two substances
Those with the highest levels of the antioxidants lutein (carotenoid), zeaxanthin (flavonoid) and beta-cryptoxanthin were found to be less likely to develop dementia after years or decades than people with the lowest levels of these antioxidants. in their body. The first two substances are present in large quantities in green vegetables (spinach, broccoli, peas, etc.), while the third in fruits (oranges, papaya, etc.).
"Antioxidants can help protect the brain from oxidative stress, which can cause cell damage. "Further studies, however, are needed to test whether these antioxidants can actually protect the brain from dementia."
