정신이 흐리멍덩해지는 것을 방지하고 집중력을 유지하려면 어떤 음식을 먹는 게 좋을까. 미국의 건강, 의료 정보 사이트 ‘헬스닷컴’이 건강에도 좋고 집중력도 향상시키는 식품 7가지를 소개했다. 물 하루를 시작할 때 신선한 물 한잔이면 충분할 때가 있다. 미국 뉴욕의 영양학자인 신디 무스타파는 “체내에 수분이 부족하게 되면 피로감을 느끼게 된다”며 “이때 커피나 에너지 드링크를 마시게 되면 수분을 더 빼앗기게 돼 점점 더 피로하게 된다”고 말한다. 무엇보다 먼저 약 300cc정도의 물을 마시는 게 좋다. 바나나 2008년에 나온 한 연구에 따르면 시험 전에 바나나를 먹은 학생들은 먹지 않은 학생들보다 훨씬 좋은 성적을 거둔 것으로 나타났다. 바나나에는 뇌와 심장 기능을 활성화시키는 데 꼭 필요한 미네랄인 칼륨이 풍부하게 들어있다. 시금치 시금치는 ‘두뇌 식품’으로 알려져 있다. 그 이유는 시금치에는 루테인과 엽산, 베타-카로틴이 풍부하게 들어있는데 이 영양소들은 치매를 예방하기 때문이다. 신경학자들은 일주일에 적어도 세 번 시금치를 먹으라고 권장한다. 달걀 달걀에는 오메가-3 지방산 계열의 고도불포화지방산인 DHA가 많이 들어있다. DHA를 적당히 섭취하면 기억력과 기분에 좋은 효과를 준다. 또 달걀에는 콜린이 들어있는 데 이 화합물은 뇌 세포막을 건강하게 유지하는 데 도움을 준다. 연어 연어에는 오메가-3 지방산이 많이 들어있다. 오메가-3 지방산은 뇌세포를 재건하고 인지력 감퇴를 늦추며 기억력과 관련 있는 뇌의 시냅스를 강화시키는 효능이 있다. 또한 연어에 들어있는 단백질에는 뇌의 집중력과 예리함을 유지시키는 데 필수적인 아미노산이 들어있다. 녹차 카페인을 너무 많이 섭취하면 두통이 일어나 집중력을 망칠 수 있다. 녹차는 커피의 대안으로 환영받는다. 녹차 중에는 일반 커피보다 카페인 함량이 적은 것들이 있다. 녹차에는 카페인이 적당히 들어있을 뿐만 아니라 아미노산의 일종인 테아닌이 함유돼 있어 균형을 맞춘다. 테아닌은 정신적인 각성과 집중력을 향상시키는 효능이 있다. 블루베리 맛이 좋을 뿐만 아니라 항산화제가 풍부하게 들어있는 블루베리는 기억력을 향상시키는 효능이 있다. 2010년에 나온 한 연구에 따르면, 2개월 동안 매일 블루베리 주스를 마신 사람들은 기억력 테스트에서 크게 향상된 성적을 보였다. 코메디닷컴 권순일 기자 (kstt77@kormedi.com)

Ready to hit the sheets once the clock strikes 3PM? We’ve all been there.

Sure, that morning brew guarantees a much-needed jolt to kick off any day of the week, but it seems like one giant mug alone can’t fight off drowsiness for hours on end. And if you’re struggling to stay alert, it may be time to start thinking about what you’ve been putting into your body lately.

“What you don’t reach for is as important as what you do,” says New York City-based nutritionist Cindy Moustafa. “Energy drinks are often loaded with sugar and way more caffeine than coffee, which can cause jitters and heart racing. Even if it says sugar-free, it’s loaded with chemicals and it’s in no way beneficial to your health…I would advise staying away from them as much as possible.”

Sadly, there is no quick fix for staying focused during the day, aside from the no-brainer (hint: getting sufficient zzzs at night), but fortunately, there are healthy foods that can optimize your concentration and increase energy levels.

If you’re in dire need of boosting your productivity during the day, check out these 10 foods that will deliver results:

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 studies have also shown 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. Experts recommend eating oatmeal, which is low in calories and will help 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

Need to perk up in the AM? Enjoy some feel-good dark cocoa rather than coffee. “Dark chocolate boosts serotonin and endorphin levels, which are associated with greater concentration,” says Natalie Stephens, clinical dietician at The Ohio State University Wexner Medical Center. “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.”

A 2013 study even concluded that those who drank two cups of cocoa every day for a month had improved blood flow to the brain, performing better on memory tests. But just like with any treat, be mindful of the calorie count and always aim for the highest quality. Experts say one square of dark chocolate during the afternoon slump should be sufficient.

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,” says Moustafa. “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. A 2010 report published by the Journal of Agricultural and Food Chemistry revealed those who drank blueberry juice every day for two months significantly improved their 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,” says professional health coach Lori Shemek. “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.”

Need to jazz up your eggs for breakfast? Shemek recommends pairing them with some salmon for a satisfying meal to start your day.

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. Also, too much consumption of caffeine can cause headaches, which will only hurt your concentration. While green tea has always been hailed as a coffee alternative, no two brands are created equal. Some may have less caffeine than a regular cup of coffee, which can actually be a good thing.

“Green tea does contain a more modest amount of caffeine balanced by the amino acid theanine,” says celebrity nutritionist JJ Virgin. “Studies show theanine improves mental alertness and focus. If you need that afternoon pick-me-up, green tea is your ticket.”

Beets

“This dark red root may be the new kid on the block for promoting better memory, focused concentration and overall cognition,” says Shemek. “Beets contain nitrates that can dilate blood vessels, increase blood flow and oxygen to the brain, thereby improving mental performance. Add beets to salads, roast them or add to juices for optimal brain health.”

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. A 2008 study found that students who ate the golden fruit before an exam actually did better than those who didn’t. 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.

“Spinach is loaded with lutein, folate, and beta-carotene,” Florida-based dietitian Tara Gidus tells Real Simple. “These nutrients have been linked with preventing dementia. I know neurologists who recommend eating spinach at least three times a week.”

Eggs

You may be tempted to ditch the yolk when preparing eggs, but some experts actually insist on keeping it. “Whole eggs, yolk included, are a dense source of the omega-3 fatty acid DHA,” says Shemek. “Research has shown that 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.” To save time, Shemek recommends boiling a batch of eggs for the week ahead to have them on hand.
