Khaberni - A study conducted by researchers from the Medical University of Lodz in Poland showed that foods rich in natural nitrates, especially beetroot juice, may play an important role in supporting physical fitness and promoting healthier aging.
Scientists reached this conclusion after analyzing data from dozens of previous studies, where the results showed that beetroot supplements improve in most cases the body’s endurance and muscle efficiency and contribute to speeding up recovery after exercise, especially for people not accustomed to regular physical activity.
The researchers attributed these benefits to nitric oxide found in beetroot, which works on dilating blood vessels, increasing blood flow to muscles, and reducing tissue oxygen needs during physical activity. As a result, the feeling of fatigue decreases and movement efficiency improves, which is particularly important for adults and the elderly, as physical reserves gradually diminish with age.
As for brain functions, the results were less clear; some studies showed slight improvements in attention, reaction speed, and some memory indices when consuming beetroot juice, but researchers affirmed that conclusive evidence on its sustained cognitive effects is still insufficient. However, they indicated that improving blood flow could potentially support brain functions, especially when combined with healthy eating and physical activity.
The authors of the study pointed out that beetroot supplements could represent a safe and cost-effective option that could be included in healthy aging strategies to enhance physical fitness and support overall health with advancing age.
