You can keep your mind “sharp” for more years if you put a healthy and tasty juice in your life!
Researchers from Wake Forest University in North Carolina, USA, have discovered that it has a powerful anti-ageing effect and can protect the brain from neurodegenerative diseases such as dementia.
According to the findings published in the Journals of Gerontology: Medical Sciences, beetroot juice slows down the ageing of the brain thanks to the nitrates it contains.
The benefits of the juice, according to the researchers, are strong when combined with mild physical exercise, another well-known anti-aging measure.
In the trial, 26 men and women aged 55 and over (participants were not exercising regularly, had hypertension and were taking antihypertensive drugs) were asked to exercise three times a week for a total of six weeks.
Their workout included a 50-minute walk on an exercise treadmill. Half of the participants took a beetroot juice supplement containing 560 mg of nitrate before their workout, while the other half drank a “placebo juice” with minimal nitrate.
Nitrates are known to improve blood circulation while enhancing athletic performance.
In the beetroot group, increased brain oxygenation was observed but also a stronger presence of nitrates after exercise.
“Nitrates are very powerful molecules” explains to EurekAlert Jack Regeski, one of the researchers who carried out the study, “as they are targeted to the areas of the body that are hypoxic, i.e. need oxygen, such as the brain”.
“Compared to exercise alone, the combination of exercise and beetroot juice supplementation led to increased brain coherence to a degree that resembled that seen in younger people,” adds Regzeski.
The study looked at the combined benefits of exercise and beetroot for the first time and the results look promising!
