A 2018 study from National University highlighted that the brain, despite being only 2% of body weight, consumes about 20% of daily energy. This immense energy demand means that what you eat directly impacts your cognitive function, so the question isn't just *if* you learn better after eating, but *what* and *when* you should eat.

Research has shown that while the brain relies on glucose as its primary fuel, excessive intake of added sugar can impair cognitive function. This can have a significant impact on students and others who engage in intensive learning, challenging the common misconception that a sugary snack will provide a lasting mental boost.

Studies show that students who are chronically hungry or have poor nutrition tend to have poorer grades and test scores. This compelling research supports a vital link between healthy food and academic performance, influencing everything from memory to overall cognitive function.

According to the CDC, students who skip breakfast are less likely to report earning high grades, highlighting a strong connection between diet and academic outcomes. This powerful insight underscores the critical question: **How does nutrition affect school performance?**

According to the World Health Organization, micronutrient deficiencies like iron, iodine, and zinc impact millions of children worldwide, directly impeding cognitive development. This is one of many ways poor nutrition can significantly affect learning and overall academic performance from an early age through adolescence.

Though only about 2% of our body weight, the brain consumes a remarkable 20% of our daily energy intake. This significant energy expenditure means that the fuel you provide your body directly affects your brain's performance. So, how does food affect your ability to learn, and what can you eat to optimize your cognitive power?
