Many are familiar with the saying “You are what you eat”. Are we, really? Students who are studying for exams usually binge on food that can ‘increase brain power.’ Aside from that, there are plenty of supplements in the market which claim to boost memory. Which ones are true and which ones are not? Let us explore the science behind the food, brain, and the in-betweens.
What we know
As living, breathing beings, we primarily eat to survive. It’s a basic necessity. However, we do not always eat out of need, sometimes we eat out of want. Giving in to our ice cream craving on a hot day can improve our mood, sometimes dramatically. Aside from providing our body fuel, food can affect how we feel and think.
Although it is a relatively new area of research, scientists have found out that just seeing, smelling or thinking about food can alter the chemicals in the brain. Chemicals such as insulin, ghrelin, leptin, dopamine, and many more influence the activity of the brain. Hence, what we eat can affect specific receptors and have the capacity to influence cognitive function and even emotions. What we know at present is that certain food components influence brain function. The familiar ones we know from science class: glucose acts as fuel for the brain, fat helps strengthen the synapses, and proteins can act as neurotransmitters. Recent research suggests that some food can influence alertness, memory, and function. But the question that remains unanswered is: which food do we have to eat to help us do well in school?
Our brain consumes A LOT of energy. Scientists hypothesize that it uses up to 20% of the total energy generated by our body and majority of that energy is used to fuel electrical impulses in the brain cells. Hence, a well-fed brain functions better than a starving one. Furthermore, proper diet and exercise can positively affect brain performance. That said, some food groups have already been found to influence learning, cognition, and memory. Here are some common brain food myths and the science behind them.
- Eggs - We have been told to avoid eggs (especially yolks) because they are high in cholesterol. However, recent studies have shown that eating eggs do NOT increase the risk for heart disease. In addition, the choline found in egg yolks actually improves memory. So next semester, include boiled eggs in your lunch bag.
- Candies - It has been said that eating candies can boost your brain function while reviewing. While candies can be a quick source of glucose, too much sugar, as we know, is bad for the health. So ditch the candy and try munching on the next food item instead.
- Peanuts (or nuts) - This has been a two-edged sword for students because it is said to boost both memory and pimple production. The truth is that nuts can help improve the cognitive ability of the brain and possibly be able to slow down memory decline. And fear not, there is no relationship between nut intake and pimple breakout.
- Fish - It is said that eating fish can make y
