When we eat we must consider the brain just like any other muscle that, in order to work well, needs nutrition!

The brain, in fact, absorbs 20% of the food that we eat
What are the "fuel" foods that boost cognitive abilities?

Food for the mind. 

Cauliflowers, broccoli and Brussels sprouts are particularly rich in folic acid and vitamin K, boosting the health of the central nervous system and cognitive functions such as attention, memory and concentration.

Whole grains provide energy to the brain all day, because they release glucose in the blood slower than traditional grains, promoting reflexes and the ability to concentrate.

Dark chocolate is antioxidant and anti-stress, and improves blood flow in the brain. 
Thanks to the rich presence of flavonoids it protects the cognitive functions from aging and preserves long and short term memory. 

Blueberries protect the brain from free radicals and environmental toxins thanks to proanthocyanides, polyphenols with strong antioxidant power. According to research carried out by Tufts University in Boston, eating blueberries slows the loss of short term memory.

Nuts are a precious source of Omega 3, Omega 6 and vitamin E, a cure-all for the nervous system, cerebral function and regulation of serotonin levels in the brain, the good mood hormone.

Fatty fish rich with Omega 3, in particular EPA and DHA, help protect cell membranes by promoting cognitive functions and intellectual, educational, or work performance. Recommended: herring, salmon, sardines, mackerel and trout.

Blackcurrants are filled with vitamin C (three times the amount contained in oranges), an anti-oxidant that increases mental agility, protects from aging and from neuro-cognitive disorders.

Pumpkin seeds are rich in zinc, a precious mineral to improve memory and cognition. In addition, they also contain tryptophan, a serotonin precursor that aids rest and good mood.

Green tea, rich in polyphenols, acts against free radicals and cellular aging, improving brain performance and delays the effects of brain aging, offering a precious contribution against cognitive disorders.
