Can't focus? Having a rough start to your workday? Are you staring out the window or fidgeting with desk accessories more than actually doing work? Well it’s time to refocus! Eating a healthy breakfast is obviously your first line of defense, however certain foods have been suggested to improve mental focus throughout the day.1. BlueberriesBlueberries aren’t just delicious. Just one handful has been found to improve concentration and memory for up to five hours after consumption. They are packed with purple antioxidants known as “anthocyanins” that researchers think stimulate the brain by increasing blood flow and bringing more oxygen to all parts of the body.2. Egg yolksEgg yolks are the richest source of choline, a vitamin that helps brain cells communicate. The protein and heart-healthy fats found in eggs are also excellent for keeping you focused. Don’t fear the cholesterol in eggs – the 2015 Dietary Guidelines for Americans reaffirmed that eating eggs does not increase your risk of heart disease.3. TeaSeveral studies suggest that consumption of tea enhances cognitive ability and academic performance in teenagers. This might be due in part to the high amounts of healthy antioxidants known as “catechins” present in tea. The caffeine in tea has also been proven to increase alertness and concentration.4. SalmonA large portion of the human brain is made up of omega-3 fats. So it’s no surprise that consumption of salmon (which is rich in the omega-3 fat DHA) keeps your brain functioning normally. Levels of DHA in your brain decline with age, making salmon a true brain food!5. BeetsBeets and beat juice have been suggested to be a natural way to fight age-related memory loss. Beets are a source of nitrates which help stimulate dilation of our vascular system and thus increase blood flow to the brain making you more alert and healthy.6. Dark chocolateDark chocolate not only boasts a ton of antioxidants but studies have shown that consuming this delicious treat in moderation causes your body to release endorphins that may result in better concentration. Just two ounces per day can help boost your memory and prevent heart disease by lowering your blood pressure.
