While working on a treatment for Alzheimer's disease, researchers at the American Academy of Neurology have identified a number of foods that could help prevent the disease. In general, these studies show that some foods are actually very effective allies of our brain. Here are some of them.
Our brain is mostly composed of fat. But unlike those contained in adipose tissue, these fats do not serve as a reserve: they enter into the composition of the biological membranes of neurons.
This fat will help protect neurons and will promote the creation of new connections between cells.
In particular, we owe this fatty structure to omega-3 fatty acids, of which salmon is one of the best sources.
According to a study from the University of Maryland (USA), omega-3 fatty acids reduce the risk of cardiovascular disease, improve memory and cognitive performance, and combat depression.
2. The red fruits
The ageing of the brain is partly attributable to the oxidation of neurons, caused by free radicals.
But blueberries, cranberries, blackberries or raspberries, contained concentrated high doses of antioxidants, which fight free radicals and boost our brain.
The human body does not produce antioxidants, it is imperative to bring them through the diet.
According to a study conducted by Wake Forest University and published on the website of the scientific journal Nitric Oxide: Biology and Chemistry, beet, rich in nitrate, would facilitate blood flow, which also feeds the brain.
A daily intake of beetroot would therefore improve blood flow in certain areas of the brain that over time become depleted of blood and oxygen, resulting in senility.
Beet is also one of the vegetables with the best antioxidant power. Antioxidants are compounds that protect the body's cells from damage caused by free radicals.
4. Olive oil
In 2015, a team of researchers developed an "anti-Alzheimer" diet that could reduce by 53% the risk of developing dementia such as Alzheimer's disease.
This diet called "MIND" (Mediterranean-Dash Intervention of Neurodegenerative Delay) combines the DASH diet and the Mediterranean diet, rich in olive oil (extra virgin).
In addition, polyphenols in olive oil have been shown to increase learning and memory abilities in mice.
Your mom was right to tell you to finish your spinach!
Spinach and kale are among the most powerful anti-ageing vegetables.
They are rich in folic acid (vitamin B9) and vitamin B6, two types of vitamins known to protect the brain and that would prevent Alzheimer's disease according to a study published in 2013.
6. Maple syrup
Do you like to start your Sundays with pancakes covered with maple syrup? Your brain says thank you!
A study published this year demonstrates the beneficial effects of maple syrup on the brain.
It can protect cells from time-related damage.
Indeed, maple syrup contains more than 100 nutrients that can protect the cells of your brain!
