5 Negative Effects of Sugar on the Brain

2. Impairs Memory and Learning Skills

According to Forbes, people who consume too much fructose— otherwise known as added sugar—produce less of the chemical brain-derived neurotrophic factor (BDNF). As BDNF assists the brain with learning and the formation of new memories, without a sufficient amount of it the source says “we can’t learn (or remember) much of anything.”

Additionally, research out of UCLA found that a high-fructose diet actually slows the brain down. In the study, it was found that rats that consumed too much fructose “had damaged synaptic activity in the brain, meaning that communication among brain cells was impaired.”
