Sadly, there is no quick fix for staying focused during the day, but fortunately, there are healthy foods that can optimize your concentration and increase energy levels.

- Oatmeal

They say breakfast is the most important meal of the day, and with good reason. Not only does it give you the first boost of energy to start your day, but breakfast eaters are at lower risk for obesity, hypertension and diabetes, in comparison to those who prefer to skip it.

While it might be tempting to savor sugary cereal or a doughnut, it’s crucial to start your day on the right note so you can stay focused, fight hunger, and avoid packing on the pounds easily. Oatmeal is low in calories and helps you feel fuller longer. To jazz up your meal, load up on fresh fruit for a touch of sweetness or cinnamon for some spice.

- Dark Chocolate

Enjoy some feel-good dark cocoa rather than coffee. Dark chocolate boosts serotonin and endorphin levels, which are associated with greater concentration. It’s also a source of antioxidants, vitamins, and minerals, such as potassium, copper, and magnesium, which can work with a healthy diet to control blood pressure. It’s also lower in fat and sugar than milk or white chocolate, which is better for diabetics and really anyone interested in cutting back on sugar intake.

-  Water

Seriously, sometimes all you really need is a glass of refreshing water to kick off the day, especially if you had a rough night. Thirst and dehydration can cause fatigue. If you reach for a cup of coffee or an energy drink, it will actually dehydrate you further, causing you to feel worse later. So before you do anything, drink a tall 10-ounce glass of water. Squeeze some fresh lemon in it for a little extra kick.

- Blueberries

Not only are blueberries wonderfully tasty and rich in antioxidants, but they've also been said to be a memory booster. Drinking blueberry juice every day for two months significantly improves performance on learning and memory tests. Whenever those snack cravings kick in, consider enjoying some fresh, ripe blueberries over sugary sweets any day.

- Salmon

Salmon is a concentrated source of omega-3 fatty acids, which help rebuild brain cells, slow cognitive decline, and also strengthen the synapses in your brain related to memory. The protein in salmon contains amino acids, which are essential for keeping your brain focused and sharp. Look to add salmon where you can to maximize your brain power.

- Green Tea

If you’re feeling drained by mid-day, think twice before grabbing that extra cup of coffee. With those extra sugar additions, it can easily rack up your calorie intake during the day and cause unnecessary jitters.   

Green tea does contain a more modest amount of caffeine balanced by the amino acid theanine. Theanine improves mental alertness and focus. If you need that afternoon pick-me-up, green tea is your ticket.

- Bananas

If you’re in a hurry, make sure to grab a banana to consume while on the go. Not only are they sweet and delish, but they can also help boost your concentration. Bananas highlight potassium, an essential mineral crucial for keeping your brain, nerves, and heart in tip-top shape.

- Spinach

You could have crunchy, nutritious kale as a salad for lunch, but if you’re looking to change things up, consider trying another dark leafy green whenever the mood strikes. Spinach is known as brain food and there’s a reason why.

- Eggs

Whole eggs, yolk included, are a dense source of the omega-3 fatty acid DHA. Adequate omega-3 intake has a favorable effect upon memory and mood.

Eggs also contain choline, a compound that can help maintain healthy brain cell membranes.
