We all know why you are here, so let’s get to the point. Let’s focus on making you more intelligent and focused:

Blueberries

Because “the antioxidants in blueberries stimulate the flow of blood and oxygen to [your] encephalon — and keep the mind fresh,” studies have shown that blueberries improve “memory and concentration” for up to five hours.

In addition, blueberries contain a “cocktail of anti-oxidants, including anthocyanins, proanthocyanidins, resveratrol, and tannins”; I won’t even pretend to know what those are, but they have been shown to improve focus and even protect against cancer, heart disease, and dementia.

Green tea

It contains l’theanine and caffeine.
There is no denying that caffeine improves your focus and alertness.

What exactly is l-theanine? It’s an ingredient that has been demonstrated to “increase alpha-wave activity,” which boosts serenity and weans you off caffeine more gradually rather than all at once, which can send you into a crash.

Together, the two components “produce an improved competency to focus attention, with improvement in both speed and accuracy.” It’s a no-brainer to include green tea in your diet if you can handle the caffeine content.

Avocado

Every organ in the body, especially the heart and brain, depends on blood flow. According to WebMD, avocados “enhance blood flow, offering a simple, tasty way to fire up encephalon cells.”

Additionally, avocados are “loaded with fiber (11 to 17 grams per avocado),” which helps prevent hunger pangs.

Water

You must consume enough dihydrogen monoxide to maintain your focus.

Dihydrogen monoxide has been shown to help you “think more quickly, be more focused, and experience more preponderant pellucidity and creativity” because it “gives the encephalon the electrical energy for all encephalon functions, including thought and recollection processes.”

It is crucially important that you get enough water because every single bodily function depends on it.

Dark Chocolate

It’s not a myth, no. Focus on dark chocolate for a variety of reasons—dark chocolate, not the milky, suggary variety.

It has a trace amount of caffeine, which has been shown to increase phrenic alertness.
contains magnesium, which helps you relax, and it also stimulates the release of serotonin and endorphins, which lift your mood and make you feel good.
This doesn’t imply that you should consume a substantial amount of chocolate every day, like the appetizing-looking brick on the right, but it does indicate that dark chocolate can significantly improve your ability to concentrate in more modest amounts.

That’s it. Hope it’s useful.
