In addi­tion to studying and get­ting plenty of sleep, eating a well-​​balanced diet is cru­cial to per­forming well on final exams, which begin Friday. Chris­tine Clark, a dietitian with North­eastern Dining Ser­vices and Uni­ver­sity Health and Coun­seling Ser­vices, says the fol­lowing five types of foods will fuel your brain in order to help you succeed.

1. Whole grains, such as barley, oats, brown rice, millet, quinoa, and corn, are nat­u­rally low in fat, con­tain some pro­tein, and offer lots of fiber as well as a variety of min­erals, vit­a­mins, antiox­i­dants, and phy­to­chem­i­cals. Grains pro­vide a great source of car­bo­hy­drates, and the glu­cose from car­bo­hy­drates is the fuel your brain prefers.

2. Fish is a great source of pro­tein and is linked to boosting memory and reducing stress hor­mones. If you don’t like fish, choose other foods that con­tain omega-​​3 fatty acids such as wal­nuts, flaxseeds, and canola oil.

3. Citrus fruits such as grape­fruit, lemons, limes, and oranges have been known to improve mood. They are loaded with plenty of vit­amin C and phy­to­chem­i­cals, which are thought to have an anti-​​inflammatory effect.

4. Berries con­tain an incred­ible amount of nutri­tional good­ness in a small package. They pro­vide lots of antiox­i­dants and phy­to­chem­i­cals, which help pro­tect the brain and have also been linked to pro­moting mental acuity.

5. Dark choco­late will pro­vide antiox­i­dants and nat­ural stim­u­lants that can help to improve focus. Stick to about an ounce a day.

And do not skip break­fast. Eating a break­fast that includes a com­bi­na­tion of whole grains, dairy, and fruit may improve your short-​​term memory and attention.

The best way to boost con­cen­tra­tion is to eat a well-​​balanced diet. If you eat too much of any food it may leave you feeling full and slug­gish, making it hard for you to focus on your studies. If you do not con­sume enough food each day, it will likely leave you feeling hungry and distracted.
