Best Foods to Boost Your Brain and Memory

2. Coffee and tea

Nowadays almost everybody on earth consumes some sort of a brain stimulating beverage daily, mostly either coffee or tea. The day can’t start properly without them, which  is good news for those addicted to coffee as it was found that it provides us with the short highly desirable effects of mood elevation and increased alertness and improved concentration through its action of inhibiting the binding of adenosine, a compound that accumulates in the brain throughout the day to signal to the brain tiredness and fatigue, to its receptors. and by increasing the levels of dopamine and serotonin that activate the brain reward centers which is responsible for the good feeling that we get after drinking coffee and what could be the cause of the tolerance we develop to coffee and the increased dependence on it.

It has been shown in recent research that people who consume 3 to 4 cups of coffee daily have reduced risk of getting neurodegenerative diseases such as Parkinson’s disease, Alzheimer’s and strokes through their extensive content of flavonoids, trigonelline that transforms to vitamin B3 (niacin) when coffee beans are  roasted and the powerful polyphenols like chlorogenic acids which have many neuroprotective properties against injury while supporting memory and learning abilities.

Despite all those great benefits, everything in moderation is the key to getting the benefit without harming ourselves. People who consume excessive amounts of coffee and tea can suffer greatly from disrupted sleeping patterns,, which makes them more anxious and restless and increases their heart beats. Tea has high concentrations of tannin, a compound known to prevent the absorption of iron from the stomach and stains teeth enamels yellow. The FDA recommends consuming not more than 400 milligrams of caffeine for adults per day, which is roughly the equivalent to 4 four cups of brewed coffee.
