Did you know there are foods that can improve memory and concentration?

So, if you’ve ever found yourself wiped out because you just cannot concentrate after lunch? Maybe it’s time to take a look at what you’re eating.

If you find yourself:

  • continuously switching between several half-finished projects
  • jumping from one task to another
  • having trouble focusing.

The culprit is most likely something you ate. If you want to improve your focus and concentration it could be as simple as making some better food choices when you head out for your lunch break.

Top foods that improve memory and concentration

As a busy executive, you should be aware of these key foods that improve memory and concentration.


avocado one of the best foods for the brain

Dr. Axe, certified doctor of natural medicine and clinical nutritionist, ranks avocado as No. 1 on his list of the 15 Best Foods for the Brain. Often, the avocado gets a bad rap for being high in fat, but it is monounsaturated fat, that’s the good kind. It helps keep your sugar levels steady, which is a critical part of maintaining your mental edge throughout the day.


water with a slice of lemon or with some lemon juice will give you a brain boost

Drink water with lemon. Mix the lemon juice with water to make it more palatable. A tablespoon or two in an eight-ounce glass of water is quite effective.

Drink this a few times a day and you should soon see a marked difference in a lot of areas.

A glass of water with a slice of lemon or with some lemon juice will give you a brain boost.

Sugary drinks spike your glucose levels with a burst of energy, only to crash later when you burn it up. While lemon does have fructose (fruit sugar), the amount is so low it has a negligible effect.

Lemon also contains potassium which is critical for energy levels. People who take diuretics often have to monitor their potassium levels to make sure it does not drop too low.


salmon lunch

The old saying, “fish is brain food” has a basis in reality.

About two-thirds of your brain is a “fatty acid” called docosahexaenoic acid (DHA). The problem is the human body can’t make DHA this essential fatty acid. We have to get from the food we eat. And as it turns out, salmon is loaded with DHA.

But why do we need DHA? ScienceLine calls DHA “neuronal insulation.” You can think of DHA like the insulation on the electrical and power cords that run things in your office.

The insulation makes sure the copper lines stay intact and keeps them from shorting out. DHA does the exact same thing for the neurons of your brain. Better insulation means better functioning lines. Better neuronal insulation, better functioning brain!

Leafy greens

leafy green lunch

Kale is often considered the new superfood, but it has close cousins that are just as effective at boosting brain power and keeping you running strong throughout the day.

Spinach, collards and mustard greens (which are not the same thing as the mustard you put on your burger) deliver a vitamin K boost to your brain.

Science Daily took a look at the science behind vitamin K and delivered this cerebral punch, “People who ate one to two servings per day (of these greens) had the cognitive ability of a person 11 years younger than those who consumed none.”

What would you give to have a brain 11 years younger?

Green tea

foods that improve memory

Like tea? Need a caffeine boost? Green tea is what you need to be drinking. Green tea is not “fermented” like black tea and so keeps more of the stuff that gives you a brain boost.

Mercola reported on a small study that showed “… those who received a beverage containing 27.5 grams of green tea extract showed increased connectivity between the parietal and frontal cortex of the brain compared to those who drank a non-green tea beverage.”

We say just add some lemon to that tea!

Chewing gum

You read that correctly. Recent research is showing chewing gum provides a brain boost. The Daily Mail in Great Britain hits these three high points:

  • Gum chewers have a faster reaction time.
  • Chewing gum pumps more blood to the brain.
  • Champion chewer in Great Britain, Sir Alex Ferguson, will be very happy with the news.

While No. 3 won’t help you keep your mental edge keen, the first two points certainly will.

7. Dark Chocolate

We’ve saved the best for last! Dark chocolate is in the University of Michigan’s “healing foods pyramid.”

More importantly, it increases blood flow to the brain and other parts of the body, says Be Brain Fit.

When it comes to chocolate, dark chocolate is the best kind because it does not have added milk and sugars, both of which can slow your brain down.

8. Extra Tip: Avoid Problem Foods

Avoid problem foods during the workday. High-carbohydrate, high-bad-fat and high-sugar stuff like doughnuts, cake and pie and other foods that are similarly packed are to blame for slowing you down. And at lunch, pass on dessert.

In addition to having little nutritional value, the high levels of the good-tasting stuff actually tell your body to slow down. The parasympathetic nervous system in your small intestine senses that stuff and tells your body it’s time to digest the meal, says a report at The Huffington Post.

That’s also why you shouldn’t serve junk food at meetings. People will eat and when the overload hits their stomachs, they slow down. In fact, food at business meetings may actually make you less productive.
