When preparing for my CFA exams years ago, I often wondered if there are brain foods for studying that improved my concentration.
This resulted in some experiments and changes in my food intake.
And my, what a difference it makes – it’s as if the heavy cloud clogging my brain lifted instantly! My concentration improved threefold, and concepts just magically became easier to grasp. That’s not pure coincidence.
Let’s find out how they work and what are these super food for studying that you should try!
The magic triangle to boost work and study productivity is no secret: getting a good night’s sleep, exercise and dietary intake.
Yet, food items are not created equal. The superfoods that help you focus obtained their status by being nutritionally dense in one or more of the following good-for-you stuff for your brain:
The brain’s source of fuel, keeping us going throughout the day. The key here is how quickly glucose is released into our bloodstream.
What you need are ones that release slow and sustainable energy, simply because it provides better focus and higher attention levels (no sugar high and crashes).
Glycemic index (GI) indicates how quickly foods break down into sugar in your bloodstream. A food with a high GI raises blood sugar more than a food with a medium to low GI. However, GI is a measure of carbohydrate quality but not quantity (standardised at per 50g carbohydrates).
Glycemic load (GL) is a more accurate tool to use as it measures the blood-sugar-raising power per serving of food. In summary, GL helps you select appropriate portion sizes, while GI helps you differentiate between good and bad carbohydrate choices. The lower each number, the less it affects blood sugar levels.
A great example to illustrate the difference is watermelon – it has a high GI of 72, yet a low GL of 7. Why? The high GI is based on 5 cups of watermelon (for 50g carbohydrates), not an actual serving size of 1 cup. The low GL means one serving of watermelon doesn’t contain much carbohydrate, as it is mostly water, which means a serving of watermelon won’t have much impact on your blood sugar.
Fat has been (and still is) wrongly demonized.
A diet rich in the right amount of unsaturated fats is essential to clear thinking, good memory, and a balanced mood. Our brains are made of fat, after all.
Unsaturated fats are the good guys here. These are liquid fats at room temperature and mostly plant-based. There are 2 types: mono and polysaturated fatty acids. The former helps better blood circulation, the latter strengthens the synapses in your brain related to memory.
Synapses in the brain connect neurons and provide critical functions for learning and memory. Excess calories – especially from fast or junk food – reduces the flexibility of synapses and increase the vulnerability of cells to damage by causing the formation of free radicals.
Eat less saturated fats, which are solid at room temperature and tend to be animal-based. Excessive saturated fats causes increase in cholesterol.
A worse culprit is trans fat, which is a hydrogenated fat processed to have higher shelf life, prevalent in processed food, cookies and pastries. Your best bet is to read the nutrition labels to dissect the fat content.
Amino acids are the building blocks of your brain’s network.
They help connect the neurotransmitters which are essential for keeping your brain sharp, improving memory, concentration and fight stress exhaustion.
This nutrient is abundant in protein-rich food such as fish, meat, eggs, cheese, lentils and yoghurt.
Antioxidants are the saviour that help reduce daily ‘wear and tear’ damage to brain cells.
They support vascular health and likely help repair your neurons and damage associated with ageing and boosts immunity – great for keeping yourself in tip-top condition prior to your exams.
Fuelling our brain for optimum performance depends on the quality, quantity and type of food.
We have identified the top 15 brain food for studying for best results. Try implementing these super brain food ideas daily and notice the difference.
Rich in both monounsaturated fat and antioxidant for improved blood circulation and cell-repair.
Especially great with salads, eggs and wraps.
The brain works best with 25g glucose circulating in the blood stream – about the amount found in a banana.
It also contains a third of your daily required intake of vitamin B6, a nutrient directly linked to memory, cognition and long term brain health (yay).
Remember to bring some during exam day!
Beans are a great source of slow release of glucose and amino acids, keeps you focused and productive without the sugar crash.
Beware of excessive amounts though, we all know the uncomfortable side effects…
High in fibre and antioxidants, yet low on the glycemic index, how can any superfood beat blueberries?
A low GI complex carbohydrate, it’s perfect for those who are gluten intolerant too.
Its higher fibre content with nuttier taste keeps you fuller (and focused) for longer.
Coffee is rich in antioxidants, while also providing an energy boost to work more effectively in dire times like this.
However, do limit coffee consumption to 2-3 cups max a day. Oh, and no sugar or cream please. Yes, that’s the catch!
Loaded with antioxidants, brain-boosting compounds and a touch of caffeine, it’s a great pick-me-up during your study break.
Watch the portions though.
Sugary milk and white chocolates don’t count.
Eggs contain protein and fat to provide energy to your brain for hours, and selenium in eggs is proven to help your mood.
The cholesterol fears of eggs are overblown – so feel free to have more of this versatile, nutritional powerhouse!
Raw, unroasted hazelnuts, cashews, almond and walnuts are great choices.
Filled with health-healthy unsaturated fats, vitamins and fibre, they are a great snack to keep you going.
Do watch your portions as they are pretty calorific!
The darker the better.
Great examples are spinach, kale, chard, romaine and arugula – choose what you like and eat it daily.
They are high in iron which prevents fatigue, poor mood, foggy thinking, and other cognition issues.
A great start to your day (instead of sugary cereals), oatmeals are packed with fibre, some protein and Omega-3′s.
It has low GI and a small amount will sustain you throughout the morning so you aren’t prone to irritability or an energy crash.
Perfect with blueberries and bananas to make you feel epic.
Full of Omega-3 fatty acids, salmon is a hero in improving cognition, alertness, memory, mood, as well as reducing depression.
Have them with the skin for maximum nutritional benefits.
They are easy to cook, a simple pan-fry with salt and pepper works wonders.
Sunflower, sesame and pumpkin seeds contain a protein, beneficial unsaturated fats, vitamin E, as well as stress-fighting antioxidants and important brain-boosting minerals like magnesium.
Legendary.
Preferably brew the tea fresh or you won’t get the benefits of all those awesome antioxidants.
Just like coffee, try not to have more than 2-3 cups daily due to the caffeine content.
Rich in lycopene, an antioxidant that is particularly good for your brain and in preventing diseases.
Cook tomatoes to get the lycopene though.
Ketchup doesn’t count due to it’s high sugar content, but fresh tomato sauce do. Pasta or ratatouille anyone?
