Fgarlic in memory or difficulty performing basic tasks as age passes can be a normal part of the aging process, but not always.
In some cases it is a sign of a more serious condition, namely dementia.
“Dement is a decline in brain function that leads to confusion, memory loss, mood changes and, in some cases, loss or decline of body functions,” says nutritionist Laura M. Ali to EatingWell.
Although genetics and age play a role in the risk of dementia, there are other factors in lifestyle, such as diet, sleep and physical exercise are also linked to diagnosis.
In this regard, the website highlights the beneficial properties of black chocolate.
Black chocolate helps in cognitive function: How?
Rich in antioxidants
Like other plants, cocoa contains plant compounds called flavonols, which have antioxidant properties.
“ These flavonols have antioxidant and anti-inflammatory properties and are known to promote blood flow and keep the blood vessels healthy,” says nutritionist Ghida Arnaout.
Cocoa flavonols can be beneficial to the brain as they help protect against the loss of neurons and other forms of brain inflammation. “They protect cells against oxidative damage and reduce inflammation throughout the body and brain,” says dietist Anne Danahy.
It can help in the function of blood vessels
“ One of the main benefits of cocoa flavonols is the protection of blood vessels, allowing them to relax and expand more easily as the blood flows,” says Danahy.
“ With healthier blood vessels, blood flow to the brain improves, allowing more oxygen and nutrients to reach the brain cells, as well as facilitating the removal of residues. This is important to reduce the risk of dementia, because restriction of blood and oxygen can damage cells or parts of the brain, triggering cognitive decline or vascular dementia.”.
May reduce the risk of insulin resistance
Some studies have shown a protective effect against insulin resistance with a high flavonol diet. When insulin levels are too high, blood flow may be restricted, which affects brain function.
Although studies have found an association between insulin resistance and cognitive health, the mechanism by which insulin resistance affects cognitive function and dementia is still under study.
