According to a study cited by the National Institutes of Health, a higher percentage of ultra-processed food consumption is associated with a higher rate of cognitive decline in adults over an eight-year period. This alarming statistic sets the stage for understanding the significant impact fast food can have on your brain and overall well-being, a topic frequently discussed on educational platforms like Brainly.

According to research published in the journal *Perceptual and Motor Skills*, taking a vitamin B6 supplement significantly increases dream recall. This discovery has led many to wonder exactly what supplement helps you remember your dreams and how it might work.

Statistics indicate that approximately 92% of college students regularly consume coffee to boost focus, but what about other supplements?

According to the National Institutes of Health, the brain, despite making up only 2% of our body weight, consumes approximately 20% of the body's total energy supply, making it highly sensitive to drops in nutrient availability. This critical dependency is the primary reason why is it hard to think when you're hungry, as a lack of fuel directly impacts cognitive function.

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.

The brain consumes roughly 20% of the body's total energy, making it highly dependent on a consistent supply of fuel from food. For this reason, neglecting your nutritional needs and not eating enough can significantly affect focus, mental clarity, and overall cognitive performance.
