Carotenoids in carrots, oranges and tomatoes protect against dementia
Red, orange and dark green vegetables and fruits contain substances that can protect the brain from aging processes and help prevent dementia. Epidemiologists at Harvard University conclude this from an epidemiological study in which fifty thousand women participated.
Carotenoids & the brain
Carotenoids are found in red, orange, yellow and dark green vegetables. They have an antioxidant effect and activate mechanisms in cells that normally become active during periods of fasting and physical activity.
Study
Between 1984 and 2006, the researchers measured how many carotenoids the women received through regular foods. In 2012, they surveyed the women using a questionnaire that gerontologists use to try to determine whether the elderly may be suffering from dementia.
Results
Beta carotene is present in carrots, lutein in leafy vegetables such as spinach, while beta cryptoxanthin and lycopene are present in relatively high concentrations in oranges and tomatoes, respectively.
Conclusion
"Because increasing intakes of carotenoids is a promising and relatively simple means of maintaining brain health, further research is warranted to establish the optimal combination and intakes of carotenoids for the prevention of cognitive decline in populations worldwide."
