Although many of these studies are observational — meaning they can’t prove cause and effect — they strongly suggest that coffee is good for your brain. However, moderation is key. When consumed in excess, caffeine can cause anxiety, jitters, heart palpitations and sleep problems ( 29 ).

Does caffeine destroy brain cells?

Within the central nervous system (CNS), caffeine has a high affinity for A1 and A2a adenosine receptors. Serving as an antagonist, caffeine affects the ability for adenosine to bind to these receptors. Caffeine has been shown to alter neuronal functioning through increasing spontaneous firing.

Can coffee make you fat?

Consequently, drinking coffee can interfere with losing weight when our dependence leads us to make poor lifestyle choices and eat unhealthy foods.

Can caffeine permanently alter brain?

The authors say that effects of caffeine can build up over time and lead to measurable changes in the brain: If you’re blocking adenosine receptors with caffeine over the long term, this can result in “adaptive changes and lead to chronic alterations of receptor expression and availability,” the authors write.

Does alcohol kill brain cells?

Reality: Even in heavy drinkers, alcohol consumption doesn’t kill brain cells. It does, however, damage the ends of neurons, called dendrites, which makes it difficult for neurons to relay messages to one another.
