As both a palatable treat and necessary nutrient in moderation, sugar is a highly prized substance present in the majority of foods and drinks. However, consumed in excess, sugar is known to have adverse health effects which can infringe on an individual’s quality of life. This article aims to address and analyze the effect of sugar, specifically high fructose corn syrup, on the brain. Through the gut-brain-axis, nutrients from digested food can directly reach the brain. In other words, an individual’s diet may impact his or her mental health. This concept of brain function and health in relation to what is consumed prompts many to wonder about the short and long-term effects sugar consumption has on the brain. Thus, studies have found evidence to support a correlation between excess sugar consumption and an increased risk for the development of neurodegenerative, psychological, and metabolic disorders including Alzheimer’s and Type 2 diabetes.
